How detect the speed changes of fan using a controller ic?

I have a ceiling fan manual regulator, the voltage output that i got when different speed is 80v,120v,180v,200v respectively in my project i want to detect the fan speed changes. that means if fan is running in 1st speed then user turn into second speed it should be detect(by using in Arduino) .how can detect this?I tried to use a current sensor(ACS712) at output of a regulator then detect the current for different speed..but the variation still small cannot be detectable.

Creating copper nano particles

Be it conductive ink, decorations or just a special pigment for your paint project, Copper is nice.Only problem is grinding this soft metal fine enough to be of any good use.A not so well documented feature of food additives is that they often have "unwanted" side effects.In our case E300, Ascorbic Acid or just Vitamin C.So how to make copper nano particles with it you might wonder?Prepare a well saturated solution of Copper Sulphate, you find the blue crystals in the gardening section together with fertilisers.It is best to use destilled water and not plain tap water, if in doubt go at least with the demineralised stuff for batteries.Adding E300 either dissolved in water or directly as crystals will start a nice reaction.The copper solphate is reduced back to metallic copper.There are a few problems though...For best results you need a saturation copper sulphate solution, low temperatures and a magnetic stirrer.This produced the finest particles for me at around 5°C.But even warm or at room temp the constant sirring is beneficial for even particle sizes.The ascorbic acid is used up in the process as well.You can start with a little and see how much you end up with in terms of a layer of copper particles at the bottom.Adding more E300 will cause a "rain" of fine copper particles - once this no longer happens you know the copper sulphate is used up as well.A dark greenish color of the solution will indicate this as well.Getting the copper out of the glass...Keep in mind the copper is extreme fine!As long as it stays in the solution it won't oxidize or otherwise react.Once out and in contact with just water and air oxidation happens quickly, after all it is pure copper...I found removing the watery solution and then adding destilled water to repeat the process is a good start.The waste from the first round can still be usefull though...In the final round I try to remove as much water as I can and then add methyled spirit to prevent the reactions.You can use oil as well or do a quick vacuum drying and store it in a sealed and oxygen free container.What to do with it?As a condictive paint with the right binder it only needs some rubbing with a smooth tool to create a conductive cover with a low resistance.In a clear paint or resin it provides some stunning color effects.You can even dust the dry powder onto a freshly painted surface to get a copper look.Leave without a top coat and you quickly get an old copper or even green look.If you ever wanted extreme fine metal particles you will come up with more ideas...Like shielding or sintering....

An open letter to the support and those running this website

For a few years now good people using this website tried to make suggestions, make requests or just attempted to provide helpful feedback and bug reports.Severe bugs are usually dealt with promptly and I like this very much.For everything else though at least I start to develop a feeling that tells me your end either does not listen or does not care.Users are what keeps this section and website alive.Users provide the content that allows you to place ads to make a bit of revenue.Users fill your servers with their ideas.Users are those you should help to have it easy and enjoy being an active part of the community.I won't repeat the things users stated or requested thausands of times already.But I do state that at least got enough excuses and promises over the past few years to think I am being taken for a ride.You state the users are highly valued - valued as what exactly?You suck in user's creations like a vacuum cleaner and promote it all through endless numbers of sponsored contests.You create volume and website hits only.Quality was reduced to forcing restrictions and often totally useless standards on the user.There are articles explaining what a successful Ible needs and how to write one so it fits into the greater picture here.But where is the information how to embed pictures with the text? Oh right, that would be too nice for someone doing it or reading it, so we just plaster a block of images in a meaningless location on top of the text...I was a forum admin for a few years and if there is one thing I learned from it than : Don't mess with the users by "improving" things....Sadly Instructables never got that experience and we saw a lot of "improvements" that really absolutely no one using the website wanted or needed.The storm from that again showed how badly the user is neglected here as even reverting back to something close to what worked before took many months.The request to have some sticky postings informing the user about progress and what features might come soon was rejected again and again.Although I realised the offical suggestion to rework my last Ible so it can be published was a mistake:It highlighted the expectations you have when it comes to how you want users to create their Ibles.Creativity is not just the project in question but also how the creator wants to present it here!!I call it censorship if a person is forced to comply with standards that no one needs nor wants.We get excuses, we get promises but we simply never get anything that actually helps the user to be more creative and have it easy to create posts and Ibles.How long was it until we at least got a half working sorting option in the community section? About a year or so?You want more and better Ibles, a functioning community section again, even more revenue?Well, then give the user what they want or at least what they need to be creative again.Talk to the boss and tell him or her that we need more coders or preferably a new platform for all that actually works and is not just patchwork.Take a look at forums, blogs or other community websites that offer postings and content.See what is possible and what users create, how they create it.Search through the endless numbers of complaints here to find what you missed again, again and again.Instructables won't lose the ongoing supply of new Ibles thanks to contests but as said, volume and quantity is not quality of content ;)A user who is left struggling year after year will give up one day.Users who realise that it is not worth it won't come back after their first and only posting in the community section.And well, someone who created a really outstanding Ible for a contest and does not even make it to the final rounds might never bother again.Why is there no "open system" for contests?Anyone deciding what Ibles make it through should be open about it, post it and allow users to suggest entries he or she might have missed.Even more so for the winner selections.How many votes? What exactly made it a winner? Was it promoted by featuring it or listing it elsewhere?I don't know about you guys but even in a schools science contest the winners will be announced with some meaningful words why they actually won....Sadly, right now, I only see taking, restrictions and ignorance for the user here.The few posts from the support are highly appreciated but only a drop of water onto a red hotplate.Just for imagination:I took tons of pictures detailing my project right from the start.I took a lot of notes while creating it.I am ready to create a great Ible with it all so everyone can build or create it, I want to world to know about it.Then I click on the button to make my Ible and am greeted right away with an image uploader....Dumb enough I upload all my pics in one go.I start writing, I want to include a picture with the text so the user knows exactly why for example that screw needs to be done exactly like the picture shows.But wait...I can't drag the image down from that studip bar.Instead I am forced to create a new step for each picture that has a pecial meaning or purpose.Making a list of parts?Well, lets do it manually and by wasting precious time because there is not usable listing option anywhere to allow the creation with bullets or similar.Oh well, several hours later than expected it is time to take a preview of my creation.The images are clustered up and in no way usable to floow the text, so I start again, add more steps, drag it out even more.In the end I have about 50 steps for something that was fine in MS Word on a few pages.....To finnish I just need to somehow figure out how to get my cover images to fit into this tiny box.Cropping, resizing, again and again only to realise I might have as well used the thumb image IrfanView created in my folder...Then I do the final check.I try to make sense of the unplanned order of things and that no images makes enough sense because I need to click back and forth between steps all the time to undestand it.Then I take another look at my MS Word printout and the Ibles lands in my draft folder.When a suitable contest comes along I might try to check if the editing options have improved enough to post it.Well, I now have more drafts than published Ibles...Now imagine I would not be the only one....

L293d and extrnal powersupply issue !!

My main problem here that i have a doubt that tinkercad can go somehow wrong ! In this connection that i think is right , the l293d burns beacuse enable pin has higher voltage than powersupply pin or vc2 . But in conncection the 9v battery is with vc2 not the enable and the multimeter shows that , is there any thing can be wrong ?? (Enable is connected to arduino directly to send pwm values )

Not Able to Get to Drafts - Help!

Hey all, I haven't been able to access my draft 'Ibles for a few weeks. Whenever I click on the "Drafts" link it takes me to the Instructables home page. I can see all of the ones I have published, but as soon as I try to flip to drafts it redirects me away.I was able to finish up and publish my last project by finding the Editor page in my browser history, but I can't do that for other ones that I haven't opened since I got a new computer.Is this a bug that's been going around or is there a different way I should be accessing the drafts?I appreciate the help!

Design criteria for Ibles....

I just noticed that we have now standards that need to be followed if you want to publish an Instructable.Standards are good but not so much if the editing options for an Ible are at a standard from the year 2000.If I had fun designing something as simple as whistle that shall be created in a 3D printer: Then why would I need images showing how I designed it?Or why would I need images for the print settings or idea behind it?A community goes both ways!The editing tools are still sub standard and the images handling is a bad joke.If I need to explain something complex with the aid of images then of course I want the images in the right spot with the text - ever thought about this or visited website that offer similar after the year 2000?Usability is not just a means to provide the same look on all browsers and devices or to be able to use the most basic way to convert a website into a PDF.Usability is also for those who create it but that part seems to be lost for years now no matter how many times people ask, suggest or comment on the problem.I have no problem making my creations available elsewhere if that is the only way out here.If you want people to create proper Instructables then for crying out loud give them the means to do so!And fix the damn category selection bogus when posting in the community section.Has no use for years but why bother to fix it....Before you guys force people doing things your way only you should consider in what times we are and how proper usability would benefit this site....

Front door unlock with face recognition

I have a "Danalock" attached to my front door ( works with Bluetooth ) and compatible with Apples Home kit. As all standard front doors there is a small "spyhole". All works perfectly I use Home kit to lock and unlock the front door. This idea just poped in my mind that, what if i use one of the "raspberry pi " cam or any other small cams put it in the spy hole, then some how program it to connect to Pi so it can use face recognition.lets say I avoid using any app at all as soon lets say I or any user arrives at front door the face recognition allows the user and just for the fun of it plays a greeting "hello & welcome user1". So there is Pi cam + pi and Danalock. I would appriciate if there are any ideas or sloutions or comments etc.

Challenge: A key defroster for opening bike locks in winter.

Hello all.So I live in Montreal, winter is long here. Every morning opening our bike locks is problematic. We fixed it partially with lube, but this post is not about these solutions.I have been looking for a device that could heat the frozen core of the lock. You can see an image attached of a product not available anymore to get the idea. I guess it was not working very well...I have zero knowledge in electronics/electricity. I thought this question could be interesting/challenging for some of you. So ideally the gadget would be:Small enough to be carried on the key chain or in a commute bag.Able to be inserted in any type of locksBuilt with a safe way to prevent unwanted switch on (to avoid burning bags/pockets/houses...Lol)Able to produce enough heat to defrost the lock Rechargeable would be best (USB best best), capacity of 5mn maybe to operate twice a day...Reasonably quick to unfreeze the lock, so you don t freeze yourself (That s why I abandon using hot pouches around the lock, pouring hot water will fix it quickly but then it will freeze again)As I said, I don t have the skills to even begin to find a solution, but I saw a lot of smart stuff here and I am curious to see what you guys would answer to that. My guess is that it must be very difficult, if not I can t see why a similar product is not widely commercialized. I think a lot of people would buy it.Thanks for the reading, I hope I picked your interest. Have a good day.

Can't delete collections / Can't change order of collections

As the title reads, I am not able to delete my (even empty) collections.I would also like to see an option to change the order they are shown in the dropdownlist while browsing i'bles. I think there MUST be a way to delete unused/empty Collections or even move their order.And as a programmer, I don't think it is that complicated to create a "delete" button (or a "change order" button maybe).Would love to read that this will be made soon..Cheers!

The Moon - What do we really know and what is possible?

If we look up then seeing the moon is the most normal thing to us there is in the sky.But did you ever wonder how it actually got there? ;)Theories are out there by the lot, including those from real scientists.One of the most common is that it all started by catching the thing and that all was perfect at the time.Over time the orbit then stabilized.Other theories include that formed when our planet formed..What they all lack is what is common and true for all other moond out there: These rotate.According to science an object the size of our moon would need to rotate to maintain a stable orbit.No one told this to our moon, so it just stays in a stable orbit anyway.The only other accepted theory, that funny enough never mentioned OUR moon, is that the center of mass must be facing the orbiting planet.Now theories can run and wild if you let schientifically people loose on a subject.Official NASA data obtained by monitoring equippment on the moon supports the theory of the center of gravity.You see, sesmometers recorded "moon quakes" but also the impact of burnt rocket stages - the later were dropped on purpose.At first everyone agreed the equippment must be faulty but going through it again and again confirmed all works fine.So what got them so exited that was never officially made public?You see, every thing with suffient mass will create a sesmic shock on impact.On earth we can located the source of an earthquake or even explosion quite accurately.Same happened on the moon only with one difference to earth.Every impact caused a ringing effect.Like a bell, the soundwaves and shockwaves traveled through the moon for very long times.An early explanation was that the moon is made from really hard rock or that it might even have a metal core.This was rendered useless once the actual mass was calculated and it turned out the moon would rip us apart while spinning around us.The term "hollow moon" was born.Another interesting thing happens when you try to track down what equippment was left on the moon during which specific mission.Everything up there must have been installed at some stage.For some things though it seems there is no record when or where exactly something was left up there.Then there is the thing with the interviews...If you check the fuzz about the first moon landing then back then you couldn't help yourself but got exited as well.None of the three astronauts however appeared to be at least a little bit exited about going where no man has gone before.Somehow like visiting Iceland for the first time only to realise someone was there before you already.But it was the moon, not some easy to reach island...And while up there we did not see any exitement either, like fully staged and planned ahead.Like a not so 100% school rehersal.Claims that it was a fake and actually filmed in some studio have been verified to be false - they really were up there.After they came back two went silent and refused any interviews about the moon.All three though never spoke about anything we did not see on "live TV"...All the missing segments, the drop outs, the silence during communications...The money...Apart from the Pentagon making a disappearing act of 6Billion US, the already planned and staged moon missions were cancelled with no valid reason at all.One mission already ready to go to the launch pad, crew fully trained and briefed.Two more ready for final assembly.Official reason back then was "We have been there, it is time to explore new things."Almost the same statement was made by Obama a few weeks after he claimed "We will go up there again!".If you take away the costs for the abandoned missions then the money blown up to the moon has a huge difference to what can be tracked back.The lost sum equals out to about 8 more moon missions plus tons of state of the art equippment (back at the time it was state of the art).If you add what the Pentagon lost we are close to 15 more missions.The now...A few years back a lot of previously declared top secret documents have been released to the public.What was a good idea however turned out to be a bit too much.Quite a few documents were included that provide missing links to "incidents, missions, money spent"...Within these piles were documents indicating that space missions of the same extend as the much later moon missions were made.Same rockets, similar crafts, same requirements for water, food and oxygen, some though with just payloads of oxygen and water.Mind you though the documents speak from proposed options and not planned missions.And none of them had any exploration within it, just deliveries if you don't mind the comparison.Those documents about the ringing of the moon and how this would impact on the things we assumed to know about the moon were in there as well.What is really interesting though is what came back from the moon.None of it actually indicate that there is suffient ressources up there to justify mining.Funny enough exactly is planned on a military style.Seems fair enough considering the military can provide the best people for such a hard job.Some normal miner might have no problems getting under ground every day but knowing he is on the moon and might never make it back is another.With all the probing done that we know of you would assume the planned mining operations would be in an area rich in minerals, metals or at least something to generate fuel or oxygen.But no, it is planned to happen "on the dark side" and in an area that appearently was never explored in other ways then taking a few blurry pics while flying around the moon.However, both Russia and China claim to have been very close to this area long before details about the mining became public.And that brings us back to the past and what astromauts stated or to be precise refused to confirm or deny.In some videos we can see movements in the background.In several adio stream we hear the comments to what happens in the videos.If there is light moving around then it does not matter that is blue.You just wonder what it is and where it might have come from.Imagine the surprise if then in other videos you hear things like that the lights are back or that steam comes out of the moon like a gysir.There were official explanations for the first sightings made by the normal people when watching those videos on the NASA websites.Soon after the videos disappeared from the servers.Copies were made by the curious and quite a few videos were identified later to have contained "sightings" as well.Some even show what appears to flying machines with great manouverbilities.And if you take the high point of the happenings then it is also the same time when it was decided that we actually have no real interest in the moon.Astromauts later denied to have ever made any comments like that they are being followed or "escorted" by another craft.And the same Astromauts many years later still refuse to deny or confirm that what we could see and hear during their mission videos actually happened.Don't get me wrong but if the deny it then it just means we all saw some refections or such things.If the confirm it then we know something was out there with them.Doing neither usually means what we saw is ture enough to deny any knowledge about more details.Why then the sudden interest?Trump wants to get up there, military mining, private companies not to forget China.If there is nothing at all up there then why would they all spent money that could provide a much better living for those with low incomes?Even if it would be just for new schools and hospitals the money would be better spent if we trust the official claims about what is up there.The not so official claims....We already know NASA does not want to come with an official explanation why the moon sounds and reacts as if it would be hollow.Same for any video, audio or picture evidence indication there is sturctures on the moon or activities.Here is some of things that other people of great knowledge and with nice degrees under the belt say could, might or even is true about the moon.1. We have no evidence that the moon was always there, only what we have in record throughout history.Some claim the moon would be an artificially created structure.Indications of techonlogically highly advanced civilisations before us are there.And mining out a tiny planet and placing it in earths orbit is not far fetched if you consider higher technology levels than what we currently (officially) have.2. The satellite claim.Like the Death Star our moon could be an artifical satellite placed there for a purpose.What speaks for that theory is the impact craters on the moon.If it was never spinning or better rotating around all axis then a lot them would have been impossible.A crater always shows to some extend the direction of the impact.And on the moon they all apear to be direct and straight hits only.And even at some proper angle that against physics did not create a corresponding crater: Our plant would have been in the way.Officially it is claimed though that there would not be much of a directional crater because of the missing atmosphere and all debris settling evenly.Debris however does not explain the deformation from an impact at an angle.The satellite claim would also explain the missing depth in the craters.By the size of the bigger ones the crater should be much deeper and as said show some direction.If however the rocky surface landed there over time or is just the remaining natural hull then the craters could no go deeper.No advanced civilisation would design a stationary satellite that get a hole as soon as some big space rock hits it...3. Undocumented missions.If claims are true then we have been up there a lot more times than what our history lessons tell us.Tiny probes to analyse things, send data and so on are a thing not the the USA did.If you explain the reason for collecting seismic data by wanting to document an impact of an astroid then it is a joke.Sure it would be possible but what could we learn from the data?Nothing unless you consider that in some unoffial missions drilling was attempted on the moon.Sample collection to evaluate what is in the ground of use for future missions.Some documents now claim that all these attempts ended prematurely.Drills failed or broke, drill heads failed to go deeper and upon inspection were totally worn out.And all seemed to have happend at around the same depth.Although there is no atmosphere on the moon - if you stand on it you would be able to feel vibrations of the surface.Something astronauts would have felt during the drilling.And you can feel the difference between a vibration ending by stoping the drill and one that keeps going for a long time after...The dark side is visible in quite a few school books.Looks like the front with the brightness corrected just with different craters.Ever bothered to scan these pictures in and use some software to find matches to craters on the front of the moon ? ;)Anyways, those images show us the moon as near perfect sphere.What they don't show is how the images were actually made.They certainly did not use massive search lights from orbit to provide light for cameras.Means other sources were used, like IR, Radar, Microwaves and so on.Like we found the ruins of old civilisations by using satellites that can "see" through the forest and soil.And with that it would certainly be impossible to create such a nice and detailed image like we get from the front side.If some is edited, then why not all of it...And if all those missions we don't really know about also landed on the dark side it would explain a lot of things.All sightings seem to have disappeared to the dark side.And all leaked informations about previous missions before our first landing idicate the interest in the dark side was actually huge.They all ended though with one mission report claiming to have spotted lights on the dark side.Moving and stationary and when trying to get a better look by adjusting the orbit for the next round those lights were all gone.But audio recording indicate that from that moment on the astronauts were no longer alone and followed until turning back to earth.Several attempts seem to have been made to land near sightings on the dark side.Those where the astronauts returned home the never were the same again.Documents claim long treatment in mental facilites or suicide.The official missions appearntly started with the backstory of exploring.Some now claim it was attempt for a peaceful presence that still was not tolerated.4. Stories from involved companies.Even if NASA builds a craft themself they still need the corresponding supplies.And for a lot of things they are made outside by independent companies and contractors.Trying to track down early space mission again seems to confirm all claims about previous missions.The amount of materials provided would otherwise mean NASA actually crashed the majority of things right after take off without anyone noticing.5. Launches...So far all claims about previous moon missions or just secret ones were denied.I call this "plausible deniability".In all statements it is refered to the official launch sites.Things like being in public view and so on.What is not that commonly known is that there were a lot of capable launch sites available.After all big rockets have been tested in secrecy since we had the first.The claimed landing of the chinese started a big conundrum.At first the US claimed it never happened because there was no rocket that went up.Images prived by the chinese however clearly indicated the opposite.Not much later it was noticed that a few launches might have been misinterpreted as missle tests....What does that really mean?Quite simple: The surveillance is not perfect if the other side insists that it happened.The plausible deniablity is gone.If the US was "forced" to confrim they actually noticed the launches then it also means the chinese claims about the US doing the same could be true as well.And wasn't it a very important thing during the cold war to know when, where and why the other side launched anything?The silent agreement not to go up there again was broken many times...And although most if not all of these mission ended in orbit only it makes you wonder.What would be big deal even if all claims and conspiracies would be true?A hollow moon would defy what we know about how the universe works.With that it would also contradict some of solid laws of physics.So we need(ed) proof.Assuming we had that for a long time already then it leaves the big question of why it is hollow.Natural or artificial.Nothing natural would make sense so we investigate further.And if people still claim that they can use their little equippment to every now and then hear transmissions from the moon...Sure some things up there transmit data all the time but they do so on common frequencies and not in a range that is and never was used for long distance communications.The interest in the mon came back with our modern technology.We have watches with more computer power than what was used for the old moon missions.Materials and manufacturing methods that provide much safe crafts and space suits with a fraction of the weight of old designs.And we have new means of taking more or less limited energy up with us...We are prepared so to say.No matter what really is up there, no matter if it natural or artificial, just the fact that the moon is hollow changes our views on a lot of things....What do you think would be the best explanation for the data showing the moon rings like a bell?

Linear magnetmotor - the basics for a beginner

Designing what is said to be impossible can be tricky, so I will try to give you some tips to reach your goal a bit quicker.A lot of people these days try to start with a wheel.Makes sense in one way as the final goal obviously is something that would rotate.However, considering angles in a rotating system is far easier with a usable baseline!We developed the liear motor well after any rotating electric motor.But only because someone already invented it for us.Making it flat was then more or less about finding a need for it first, like the modern highspeed trains on a maglev principle.If you want to make something move then it makes no big difference if you do it in flat or round.Flat however leaves you more options and much easier adjustments.And you will need a lot of the later...IMHO the best size and option for linear is the N0 model railway system.Tracks are only 3CM wide and second hand carriages to salvage the wheels is cheap.Either way, how would you start?We have multiple choices, like single row of magnets or double, maybe even tripple.Same for the actual magnet orientation.Flat, angled, attracting or repulsing...They all work if you understand how they actually work.Not the principle, the magnets ;)You see, a magnet always has two poles and without trickery both poles will be of even strenght, size, angle to each other and so on.Playing on a small and flat track with little resistance allows to use tiny magnets, like 5mm disc ones.If you follow the common concept of two magnet rows either side at a slight angle then you are half way there.People spent a lot of time trying not only to let the cart being attracted by the first magnets but also to let them pass out at the other end.In case you wonder why:Being able to be "sucked" in means you will have some force pulling on your cart from the next stage.Being able to fully pass through and preferably gain speed, means the cart would go from one set of magnets to the next - motion is accomplished.Let me give you my personal favourites for 5mm disc magnets:1. The rows are at an angle of 4-5° like a slim V-shape.2. Same as above by with the orientation changed by 90°The first basically means you have the magnets facing up while in the second you would have them mounted vertically.Both have good and bad sides and I think it is easiest to start with the first option.Here you would have a row of magnets at a slight angle either side of the track.Lets say it is all pointing away from you, then the north row would be left, south row on the right of the track.If you start narrow or wide depends if you want attraction or repulsion forces to work with.Again, it makes no big difference really, just a different way of operation, most seem to prefer repulsion though thinking the forces are greater - this is not true though ;)A very often copied way of mounting the working magnet (s) on the cart is by placing a magnet with south facing down on the left and one with north facing down on the right of the cart.Here you have the big problem of manipulating fields.The forces are quite strong and it seems the obvious choice but should be left for the advanced classes.Let me try to explain:No matter the site of your work magnet it has a very narrow acting field.Means you have a lot of attraction forces going only downwards and not providing any energy to move your system ;)If you orientate a magnet (stack) so north faces to the right and south to the left on either side of the cart you have more options.If the stack or single magnet has the correct length to match the angle of the magnet rows then a funny thing happens.Assume the outer most magnet is at about the same distance from center as the first magnet in the row.Means the inner most and opposing one is further away and the attraction forces gain the upper hand.While moving along though it moves away from the magnet row and whie still gaining force the last magnet in the row stops the cart dead center.This is the common scenario you see on the web when people try and fail.Now if you change the length of your working magnet and position in relation to the magnets in the row you can use the changes to your advantage.You can add slim disc magnets either side of your stack and observe the change in behaviour and where the cart starts to be repelled or gets stuck.In a bad case it starts fast but then stops with a big wobble back and forth.The perfect balance and size means the cart is attracted once it comes close to the magnet rows.There should only be a tiny sopt of very little repulsion right before the cart takes off.Like a hair trigger on a good gun if you know what I mean.It should then see some accelleration till about magnet 5-7 in a row of 14.From there it should level out and roll trough and keep rolling.I assume your first attempts now get you to the point where you cart start really nice, slows down a bit and seems just to miss a tiny extra push to make it out.It it shoots to the last magnet in the rows and then settles back to one or two before the end you are close!We have now two basic ways of manipulating the magnetic fields in our favour, or to "cheat" phsyics.Closing the gap.You will have realised by now that you need at least two stages for your system to be tested properly.Preferably 3 to get a 120° angle in a rotary conversion, but 5 would make sure there is hickups.This also means distance is now something to play with.Remember the pull before get at the same level with the first magnet in the rows?This is the first force we utilise by bringing the second stage at a distance CLOSE to take over the pull.Close because we don't want it to pull the cart out just like that.It would create a big "bump" and in a rotary system massive and unwanted vibrations.Instead we weaken the last magnet in either row.We still want to keep its pull but not so much the holding force that makes our cart go stuck here.Placing a magnet orientated in the same direction as your rows at the end of the row will change how and where the field of the last magnet in the row goes ;)Just to be precise: If the magnet in the row is north up and south down then the added magnet should have the poles 90° to that and in the same direction as the row.Depending how high, how close and with wich pole you place it the fields will change.You want to lower the locking force by at least 50% here - that will be suffient to overcome the holding force and gives the next stage a good chance to take over.It can also help to provide a sacrificial pole below the last magnet in the row.Again if north would be facing up then the lower magnet would also face north up but with a small distance to the upper manget.Ok, what happens here exactly?If I would want to be precise here you would need to read an awful lot, so make it simple...The lower magnet provides a way for the upper magnets south pole to get somewhere else instead of back to its original north pole.It also means there is another north pole "pushing" the north of the upper magnet more flat at the bottom half.This weakens the field strenght.Distance is key.The added magnet at the end does a similar thing.It provides attraction or repulsion forces that affect the field shape of the last magnet in the row.Imagine you have north facing towards the last magnet:You would push the last bit of the field up while also providing a very sharp end instead of a big round shape.The south pole of the last magnet also gets attracted by this added magnet, even more with one magnet below it.With those two added magnets you should be able to fully overcome the binding effect stopping your cart.It won't start and keep going when you let go of it half way down the track though, you need to start with the first magnet or give it a push to overcome the first binding effect.After that momentum takes over.If it really is that simple then where are all the successful videos about it?They are out there, you just need to look quite long for them.Most people still literally think only linear.A magnet has north and south and we can't change it - but we can...With field manipulations as above and shielding we get so much more than what physics currently dictates.Keep in mind that adding shielding under your rows of magnets will also affect how all works together ;)Some people forget this when using ferromagnetic things way too close to their testing area.Distance is also vital to keep in mind when experimenting.The closer two magnets are greater their forces to each other.You can utilise this for example by lowering magnets that seem to be far too strong in your configuration and cause a binding effect ;)And as said, shielding is nice thing for triack too - imagine what would happen with sielding on the sides of your magnet rows... ;)Make a negative into a positive!Extremly strong binding forces at a certain point in your track design can mean you might be able to utilise it instead of trying to waste it.Added magnets can divert the field to quite some extend.Shielding however can also direct them somewhere else - like in the core of a transformer where it all goes in a great circle.Even strips of shielding connecting magnets from one row to the one on the other side of the track can be utilised.Like that you turn two small magnets into one long one with twisted poles at the end.Provides more field strenght too and makes it good for areas with little to no attracting force to the cart.Then there is bigger design...Some people add a center magnet.With one on the cart and one in the center of the track you can create a cancellation field.The rows bind while the center magnet wants to push.If place where there is still enough forward momentum or even acceleration but close enough to the binding magnets it is possible to greatly lower the binding effect.But keep in mind you need to consider the added repulsion or compensated the field so it is most active towards the moving direction and less strong to where the cart is coming from.Advanced manipulations.You can machine magnets, sandpaper, file, grinder, CNC....Imagine you cut a square dice magnet from one corner to the other.Depending on how you have the field orientation you can end up several variations.But if north faced up in your dice then it will still face up in the cut pieces!Cut a pyramid and you end with a big flat south pole and a pointy north pole - and with extreme field strenth in this pointy bit.Similar story with half moon shapes.Imagine you machine a flat block magnet so you have a half moon with its pointy bits facing down and big round bit up.If north was up in the block and you shape the moon correctly then you end with two strong south pole points and a north pole that is strongest right between those points.Why is this so interesting you might wonder?Imagine you already know a magnets pole does not care if gos back to its own opposite or that of a different magnet.Then you also know you can machine and shape magnets to your will.Now imagine that for a change:Precisely machined pyramids that have the top chopped off.All tops in this example facing being the north poles and big bottom south.If you then machine a precise iron core block you make a nice cube.With magnets we need really good glue and a good press to make it happen.But if the center core is of proper size then we end with a block magnet that has a south pole on all sides.Of course to be 100% perfect we would need a zero tolerance gap but good glue and high forces can come quite close.Works as a sphere too but would even have clue where to start to machine the magnets LOL

Repulsine - the great mystery...

Even before the repulsine saw some attention during WW2 there were sightings of what we know call the classic UFO shape.Be it in Austria, Poland or other places in Europe, people reported weird disk like thing with a dome flying around.What leaked in images and documents after the war shoed that the repulsine looked basically identical to what people saw as a UFO in the sky over big parts of Europe.Then again, the repulsine appearently never made it a usable stage, same for most jet fighters at the time and still they flew around...If we now just take it for granted that actual test flights really happened back then you might wonder why we did not see any after the war anymore.For most critics it is a simple sign of facts and "confirms" that the replusine might have been a nice idea but never anything that really left the ground.As said, I often like to dig deeper and in this case the digging took far more years than what I planned on.I can not provide any solid proof for the following but I am sure even a sceptic will come to similar conclusions after reading it.Try to find some "eye witness" reports from people who saw the so called "Roswell UFO".Yes the one that made Area51 so secret and famous...Reports can be boiled down to some essential features of the hull, for those who saw it proof that it is alien.Three distinct round shpes on the underside, like you add the bottom of an egg to a round disk.Said disc of the bottom was also shaped like a wing, or the flying disk toys our kids like to play with.On the other side the shape grew up like a half shphere with an added cone or round top on it.On these area they claimed to have see engine outlets or similar and appearently the top cone was spinning in another direction than the rest of the UFO.Now I am no expert for Roswell but if I leave area and time out then I could have been fooled to think these people discribed exactly the same thing people saw a few year eariel flying over Europe.The Roswell UFO was not from another world, just stolen from the looser of a really bad war.What was seen was a working Repulsine, be it an original or something the US created from the 5 prototypes that disappeared after the war.Ha, ha, good one, then why don't we saw them flying after this anymore?Well, for starters it was a testflight gone wrong.Presumable it was planned to be limited to Area51 but the pilot lost control.Considering the Nazies appearently did their best to kill everyone involved in the project before the aliies arrived it is no big surprise.What that test flight would have shown is the impossible manouvers people already witnessed over Europe.90° or more turns at full speed instead of making a turn like a plane, sudden changes in alitude as well as accelleration on a level that makes even modern rockets blush.And if it really was the first bigger testflight they did it explains the big secrecy about the Roswell incident and what followed and created Area51 as we knew it.A "weapon" capable of these things would mean total dominance and options to impove planes and more.So why did they not even do that - or did they?The repulsine was created based on what we call today fringe- or pseudo- sience.If there is only one peroson, or a few that can even understand the claimed working principles that it can't be science as we know it.So, lets take a look what things were already heavily used in the repulsine that "we" claim to have developed or discovered decades later.Coanda effect.When air travels over a surface then it will follow the surface.You can try this with paper strips and blowing on them as well as a stream of water and some shaped objects.Long known but never found any real use until the military picked it up.For example air inlets were then developed to utilise the coanda effect.Remember how a lot of them these days look like a ducted fan housing?The round and slightly conical shape of the inlet will actually act like an airfoil and provide lift - of pulls forward in the direction of the air flow direction of the engine.I supercars we use it to create more downforce and better aerodynamics.Venturi effect.Again a very old one but funny enough also a major factor to make a jet engine work.Tesla turbine.In the Repulsine the rotating copper disks acted like a huge Tesla turbine by using a similar effect.The space between the disks got smaller and smaller towards the outer perimiter.Due to the fast rotation the molecules were accelerated and this created a partial vacuum.We use these principles today for specail vacuum pumps but also in military applications.Harmonics.Without harmonics and resonance the Repulsine would have been impossible.And at a first glance it seems we never made any use from that bit of the machine.Then why do we design exhaust systems in such a way than already the extractors ensure a pump like action and controlled backflow?The sound a good exhaust makes is also based on using the harmonics created by the explosions in the cylinders and expanding gasses.We learned that it is far more efficient to use harmonics and resonance in an exhaust system from somehwere ;)Plasma.The repulsine was said to have emitted a bright glow during certain movements or speeds.To create plasma we need a lot of energy, not so much however if the plasma is a by-product anyways.We learned that a high enough voltage differencial in a vacuum can create a nice plasma arc.From there things like analog TV monitors were created.But we never made anything that creates plasma for any use in an atmosphere.Well, unless you start to check supersonic rocket engines and other things.The working principle is very, very close here in some applications like the ramjet.Vortex energy.Today we see all vortex energy stuff as a free energy scam or at best a waste of time.But from the inlet to the outlet the entire Repulsine utilised what we now know as vortex energy, vortex math and so on.The air is twisted and spun around so many times that it is hard to keep track - but it always happened in a harmonic and resonant fashion.In some way this is implepemented in very expensive cars to keep the ventilation system almost silent even at full power.If you ever take an expensive car apart you might wonder why the air system is not as smooth and straight as you would have expected to get this silence ;)There is more but the list would become too long ;)So, if the repulsine was really that great then why was it taken apart to only utilise fractions of it in other things?If you have something really great that combines a lot of things then no one would suspect if you "developed or discovered" some of it in other projects.And to give you a very bad comparison for the other way around:If you know how to combine a petrol engine with some long blades then you could fly!I know, we did that already but you get the point.I can give you a motor and blades but that would not mean you could build a plane or even helicopter!At that time and still today something like a Repulsine would upset the "balance of power".If claims are correct then the engines of the repulsine were only required to provide the enrgy for directional changes or speed but it flew on "free energy" as the main engine system.In lame words like a jumbo jet that only needs a small engine for the hydraulics and electricity...Another big problem is the replication even if you would have a complete and working model to disect.You see most parts were brazed or welded as screw or rivets would have been problematic in certain areas.Other parts like the Kudo horn like intake systems would even today pose a challenge if you want to replicate them 100% correct.And if your understanding of science and physics greatly differs from those who originally created the thing...If your understanding tells you a dice has 6 sides (we all know that) but in my understanding it would have 16 then you would never understand how my dice rolls ;)Bringing true free energy of any form into this world is only allowed if someone can still make good money from it.Just check solar cells and wind generators - we all can have them but our providers make sure they have enough of them as well ;)Will we ever see a fully working Repulsine again?Of course !Some people like old cars, some collect old planes or old machines and tools.A great project for people in the right trades is always to build thier own little steam engine.So to say as a reminder of how it all started.Same will happen with the Repulsine as the first really utilised free energy machine the world had.The war and killings were not what really scared the world.This happened and will happen over and over again to various extends.Really scary was once certain people realised what might happen if over there the war would end with a victory and people would have time to develop for peaceful things instead.Without the war or this idiot Hitler a peaceful war would have taken over the world by storm.Those making sure we know nothing else but paying for our fuel and energy would have lost their monoply.Times change though...We destroyed our world with our needs for fossil fuels and electricity.What is left we destroy by chopping it down, digging it out or just by building new estates on prime farm land.People are now more desperate then ever to find ways to reduce their energy bills or enviromental impact.Otherwise Google wouldn't make billions on all the fake free energy videos out there.But what would it take to recreate the Repulsine?The person able to come up with the understanding of at least attempting to build one again would need to have certain qualifications and titles.He or she would hold a Nodel price for completing some of our known laws of physics or for finding some of the still missing ones.It would be a quite hard to understand and like person too, maybe even highly autistic.The person would also have an addiction like need to complete things, add the missing bits.And of course a totallydifferent understanding on how nature and the universe work.David T. from England is such a person, or at least the closest mankind can offer so far.He can see math in his head as shapes and images.Complex math problems appear to him like developing landscapes in high detail.He even learned to speak icelandic fluently within 7 days!!Imagine such a person would develop an interest in the old pioneers like Schuberger, Newman, Tesla and so on?Where we normal people fail to see any relevance or connection a guy like David would be able to literally see how all these inventions and ideas connect.He would be able to SEE the math behind it!Knowing how something was supposed to work and combining what is known through patents, drawing, videos or reports would enable such a person to make conclusions.For example where we might just see a nice pattern when we throw a stone into an undsturbed lake such a person would also already know and see the corresponding math the created the waves and why they were created exactly like this.Assuming David has no real interest in such things, then is it possible others already try?Sadly yes and even worse they do it with kids.Learning methods that are different can bring great results.For example while we use a calculator for big numbers some kids attend really strict and performance based classes to do this with an ancient abacus!After years of hard and often painful training they are able to it with a small abacus that only has a single row of discs.Shortly after they graduate to a virtual abacus - they only twitch their fingers in the same motions they would use on the real thing, but the disks and rods are all just visualised in their heads.That however is all meant as an improvement and the kids do it because they want to and not because they are forced to.Like learning to be a chess champion before even being old enough to work...In china however we have a very selective education program.Kids are not just trained slightly different to our kids but also closely monitored on their progress.As soon as one stands out for some skill it is subject to examination.Being well above average here means it is an opportunity for the kid and the parents - on paper at least.We in the western world would see it as a viscious circle though.Over the years china developed not only a better understanding of how these special kids brains actuall do their things but also how to create tests for this purpose.What looks like impossible or nonsense to most kids will trigger a scecific response and understand in those that are special.We would create something that allows parents to know early on where the kid has really good skills and what activities should be promoted.In china though the parents receive a nicer flat or some additional income while kids are send to a far away school.Again we would refer to such a school more as a boot camp.Discipline is at least on military levels, same is the punishment system.In most cases families are not reunited for many years, phone or even video calls only happen in the rare times when western TV crews are allowed a sneak peak.I just say: If a kid would see the parents often enough then it would not only know what to talk about but also be happy to talk to them - this however you won't see.It is like they talk to some distant uncle or such.What is really scary though is how these kids are trained to see their purpose and how important it is to be the best in what they do.Imagine you lost your kid at an early age and the only thing you got over the year was letters from the government saying how well it is doing and that you can be proud of it.Then it graduates and you are not even allowed to be there on that day...After that the kid is gone for good, you get a new flat and your proud kid supports you with some nice extra income.You don't get to know where it is working, what it is doing or if it might just be attending some university.By any standards these graduated kids can be seen as a great number of genius young people.Math, music, languages, science, you name it and they will have the experts aged below 20 for it.But what do they do once school is finnished and life starts?So far no reporter or family was able to figure it out.Means they don't appear in some high profile company, they don't start a successful business or teach at any public or private school.I leave it up to your imagination where thausands of kids find secret employment once they graduated....If, at least in theory we could be able to understand all these old technologies then why don't we at least try?Everyone has a goal, some desire a happy family and nice house, other need fame or just money to be happy.With that comes greed.You might have a really nice car but that does not mean you would give to some neighbour for a trip.Even if it just a nice rose garden, you might not want to share the views with anyone.This is true on all levels and we created a term for it "Need to know basis".If you just operate a press in a factory then you don't need to know when or what the next job is that comes for your press.You will know when it arrives and can check the documents attached.You don't need to know that your council is expanding and it is only seen as a courtesy to let you know on some notice board or in the local newspaper.And even our government does the same.What we do from the first days of our new baby we do on all other levels in the same way.What the baby does not need to know we won't tell or show.But we provide all the littly anklebiter needs to develop and be happy.Changing nappies, feeding, proving comfort when sick or having a nightmare.Later we teach language and other skills like walking.It goes on as you know...Humanity as a whole is like a little kid as well.If we would know all the little, dirty secrets then we would riot and go mad.Things that are of no concern are nothing we need to worry about, so we don't get to know them either.Knowing how build the latest fighter jets is seen as a thing that would give a possible enemy an advantage.Makes a lot of sense to everyone as these things might have to protect us one day.The questions that remain are:If humainty is a child, then how old are we now or when do we graduate?If there is a collection of secret and old knowledge then who owns and controls it?What would it take to force the release of all the things people actually created for a better world and not to be locked away?As funny as it might sound but one answer to all these questions would be to do nice orund trip in your Repulsine.Fly over ever single country in this world.Let their guided missle and what not chase you and once enough show then how quickly you can make a 180° turn to get behind them.So called unimportant countries might ignore you and the people only enjoy a nice show.Those powerful enough will fear you and think it was "the other side" showing their superiority.Once done with your round they all will have to realise there is a new power that is at the helm now: Knowledge and understanding.No more secrets, a repulsine for everyone who wants the plans to build one.A new world would start.Ever thought about that when wondering why all these "Aliens" we see in their ships in our skies never land to say hello ? ;)Even if they would be Aliens and not just some human pilot in some experimental craft:Shouldn't this demonstration of absolute power and control without any violence tell us something?The Repulsine need to come back to life to end all this UFO nonsense and Alien theories out there.You hear the sounds, see the ligh show and impossible abilities.And suddenly most if not all UFO sightings would have a common factor again.Just because the Repulsine is claimed to be lost and that it never actually worked despite film evidence showing the opposite does not mean there is no one using the technology.A working Repulsine available to everyone would also kill the doubt on so many other old inventors and "fringe" scientists.Science and physics would need to be redifined as would be able to find a lot of missing links.I know there is not only a lot of people out there trying to get what they can about the Repulsine but also that there are others who try to prevent this.You have a really easy time getting permission examine some old and histrically important artefact from a museum than getting just a hands on approch for what remains of the Repulsine in various places.Not even decent 3D scans will be allowed.Anything like just getting a tiny pipe cam inside is rejected with the excuse it could cause damage.If the thing is a hoax and never worked then why would it be so important to never touch or move it? ;)I recently got word that two of the remaining Repulsine "artefacts" were examined by the same group of "scientists".This happened in the late 80's and said scientists were claimed to have had acces to a collection of spare parts for the original Repulsine that was lost after the war.A private collector was also mentioned who denied all access but what he had in a secure storage facility appearently disappeared shortly after his refusal.Putting all the dots and hints together it would mean that someone in the late 80's was able to get literally everything that is left of the project in his hands.Those who claimed to have seen these scientists working on the Repulsine leftovers claim they used top notch technology to do so, including 3D scanners - and those were basically imossible to get back then for any uni out there...The laptops used were said to use touchscreens and were connected to all sorts of equippment.And they did it in almost total silence, like a group who studied a performance many times and knew exactly what do when and where without the need of many words.Professional in examining something unknown all all possible levels.I was unable to get any information on these scientist or who they worked for.But if you are one of them and readin this then I would love to hear from you!

Very old shielding materials and techniques for permanent magnets and resulting possibilities

Forromagnetic meterials are not just called that for no reason.It comes from ferrous - iron.Iron has the highest permeability at normal temperatures.That means a magnet is attracted to it very strongly.We utilise this for transformer cores, the stuff inside a relay and the moving latch of the relay itself.Like current from an electrical system magnetic fields like to take the easiest route possible.Air is a very bad medium, so any iron close by will be prefered even if it is at a slight distance.You can check with a magnet, a steel bar and some iron shavings - please cover the are with plate first ;)Slightly less known is the option to also guide and extend the magnetic field this way.If you check how far the magnetic field of a magnet reaches and note that distance,then you can add some steel bars or rods at the poles - the field will extend through the metal.The most powerful example of this are the shielded magnets used for hooks or speakers.Except for a tiny area the entire magnetic flux goes through the metal.So in this lefover area the magnetic flux density will my many times greater than what the magnet alone would be able to.What most people don't know is that magnets also interact with other magnets in terms of their fields changing and distorting.The Halbach Array is a good example of this.Seen as a single magnet the array would have one weak and one strong side instead of even strenght for both.Wherever magnetic fields change a conductor can produce electricity or current.This in return causes an electromagnetic field that opposes the one from the magnets.Just drop a magnet through a copper or aluminium pipe ;)Since these distortions are widely unknow to the hobby tinkerer mistakes can happen ;)In the early days of exploring science some people already knew about shielding.And they also knew that certain metals have certain properties.Where it is quite hard to create a good coil from steel wire, copper works fine as it is not magnetic.What would then a copper shielding do?If you have two moving magnets with only a tiny gap then the resulting field distortions are quite huge.A copper shield around the magnet like a pipe would then react to these changes and also create a megnetic field that works in relation to the enclosed magnet.In simple terms it means the shield would let the magnet appear weaker or stronger depending on the field change.A quite old document I found gave some hints on how people thought in different directions back then.It was in regards to the design of a magnet motor by the way.Here various magnets were shielded in tube made of a copper-bismuth-alumium alloy.These tubes were then electrically connected so it created a single loop conductor.The claim was that the resulting electromagnetic field of this ring would drive the fields of the enclosed magnets sideways out of alignment.Like bending straight pastic tubes sideways.This "pulsating" would always happen when the magnetic binding forces reach max and so basically drastically weaken this binding effect.Another document talks about a "magnetised brass rod".A holes of the rod diameter is drilled through a block magnet.Not from north to south but through the middle where the flux is greatest.The claim here was that if that rod rotates fast enough a very low voltage with a very high current will be generated.Sounds easy and interesting enough that I might have to test one myself one day.The best one however is what I consider a hoax or being as good as Starlite.Someone back in 1908 claimed to have created a material the reflects magnetic fields.In lame man's terms it would be like an insulator around some electrical wire.The claim and some pics showed it, was that no magnetic field can pass the material.Or to be correct only a tiny fraction of what would be possible through air.A small magnet inside a longer tube of this material would create almost the same attraction to steel at the tubes ends as on the magnet itself.Measurements showed the field strength would be almost equal to a long mangnet of the same field strength.Imagine guiding the field of a big and powerful magnet through a tube around some corners or other magnets and then end in just a tiny hole for the entire flux...Too bad he never shared his secret formula to anyone knows to mankind.Isolation...Imagine you have an array of changing magnetic fields and quite strong magnets.Then you might face the problem that your focus on the "working" end neglected the other end of the magnet (stack).Providing some iron core material will keep thes field lines contained and away from interfering with your setup ;)But it also allows to use te otherwise unused end of your magnets more directly.For example by guiding to another magnet to affect its field strenght ;)Placing a sheet or steel between two magnets in a setup provides a "shared pole" so to say.If you have a north and south pole on a rotor at a distance of 5mm then a sheet of steel between will drastically weaken the strenght and reach of this combined field.It is like pulling the arch between the magnets down to make it more flat.And at and an angle the resulting field will also be slightly angled ;)Capping...When I first encounter this many years ago I couldn't really make sense of it.Quite complex..If you check the magnetic field lines with iron filings or similar then you notice how they go in a rounded manner from pole to pole.This is because the single field lines are of equal polarity and will dirve apart like opposing magnets.By capping the ends of a magnet you provide a short.Instead of diverting out like mad they will follow the cap and create very intersting magnetic field in return.If both poles are capped it is like pressing the magnet flat but without having a field on top of the oles - only aorund the center part.For this the thickness much must match what is required for the flux density.As a rule of thumb: if the end is still very magnetic then it is not enough material tickness ;)Interacting fields in a tube...This one is quite old too and seemed to have found no usable inventions apart from simple magnetic spring replacement systems.But it gave me some clues about Tesla "earthquake machine" ;)If you place a magnet in a tube and at it's ends magnets with opposing fields to the one inside then you can fix this magnet in place.Push one magnet deeper and the distance from the inner magnet to the other end will shrink the same amount.In this old paper two coils were around the pipe with the inner magnet between them.In this gap and at about the same width as the magnets length another coil was placed.Violent shaking would then create electrical energy at much higher level then modern shaker torches.In return an AC current on the outer coils would cause the inner magnet to move back and forth to create electricity in the center coil.According to the paper possible uses include: core less transformer, measuring minute changes in AC voltages, providing free power from a running motor...The last one had me stumbled for a very long time.Until I considered a different configuration.The whole thing is basically a linear DC motor - with correct timing of course.And in some motors we use permanent magnets.I am starting to wonder what would happen if we would design a rotor magnet like this?The running motor would be subject to constant field changes that affect the rotor.And a normal motor is always "even".By using four magnets instead of one we can push the field really flat.This means the area where the coil would operate (about 1/5 of the magnets area) will have a much stronger field.The resulting torque should be higher by about 25% !!Even a simple two coil model setup should show a significant increase in performance here.Timing is critical here but I tried some calculations based on 8 poles and the required "on times" for the coils.In a standard motor configuration with a single rotor magnet the coil is active for about 12° of the rotation.With a 4 magnet configuration this "on time" can be reduced to under 8° of the rotation to get the same amount of torque.An energy reduction of about 4% if you neglect losses and only think in time.If you think in terms like impulse energy then we are talking of about 15% !Shorter on time but still much higher flux density overall than for the long standard timings.Going the long run now:If you check how most DC motors work then you realise soon that for most one rule seems to followed.Only use one coild pair at a time.This is quite contradictive if you consider the geometry and options.A dual commutator would allow to use a second coil pair with a field OPPOSING the magnets instead of being attracted to it.After all: on you bike you pedal with both legs and not just one...And if you do it professionally then yu do the same as I suggested for the motor - you use the up pull of your legs as well.Doing it brushless only requires amodified h-bridge desing to drive the second coil pair at the right timing.Some will now say that it requires twice the energy, I say that for the same motor size your get twice the torque!Just imagine what that means in possible weight reduction for a motor - or its size to deliver the same torque at the same power levels when a normal motor is used ;)The more poles the more complicate the precise timing but no big deal really with modern electronics.Can it be improved even further?I though long and hard about that one until I considered EMF.A DC motor produces a lot of it when the elecromagnetic field collapses in the the coils.We do not utilise this energy...There is a tiny delay until the released energy levels are at max.My theory is that it should be possible to divert this energy into another coil set.If that coil is not the next active but still within a strong enough field area then the EMF would actually add to the drive of the motor.Only downside is that according to my calculations at least 16 poles would be required to get an optimum result.Way above of what I can create in my little garage :(In theory it should then be possible to reach about 98% efficiency for the motor....

"Sonic" drilling or cutting

If we look up sonic drills today we usually get some fancy machines driving pipes in the ground, preferably softer ground.But the term includes all types of machines that use sonic vibrations to advance through a media.With the ancient and claimed to have never existed technologies in mind I did some digging...In the food industry vibrating knifes are quite common, same for "air knifes" on softer food.Even in the meat industry they find more and more uses now.Ultrasonic cutting or welding is the same thing and included in "sonic".Same for some experimental sub sonic drilling methods currently being tested.The general idea might be as old as using vibrating equippment to compact stuff, like concrete, bricks and so on.What you can compact by vibration you can also make "fluid" by vibration.Industrial feeder systems utilise this to the extreme by even making light and fine particles like flour move like water without causing any dusting.What all the techniques have in common that a suitable tool or tool head is used and that it is attempted to use the most suitable vibration frequency for the job.Anyone operating an ultrasonic welder knows the pain of finetuning for a new electrode or just new part to be welded.What does that tell us now that makes the understanding easier?Take a bottle of ketchup, preferably one that is still quite full.Turn it upside down and noothing comes out.Shake it a bit and you are either lucky or drowned in red.But hold it at an angle and start tapping it and the red sauce flows out easily.What it true for most newtonian fluids is in some way also true for non-newtonian fluids.Ever mixed corn starch and water to make these funny experiments with it?Hit it hard and it reacts really hard and is not sticky at all.Leave your hand resting on it and in sinks in and sticks to it.Stirring it very slowly is easy, go faster and you get stuck.You can do similar things with by using an external source for vibrations.For example a vibration speaker mounted to a smal cup of the goo.If you place sand on a sloped piece of plastic or sheet metal then at a low angle it will pile up easy and stay.Start vibrating the plate and the sand will start to flow off.Works fine with a vibration source mounted to a piece of steel bar or rod and a bucket of sand too.Trying to press it into the sand requires a lot of force, especially once you are a bit deeper.Let it vibrate properly and it slides rights down.If we can do the simple stuff as well as really complicated stuff in the industry then what about other materials?So far we use vibrations to make things move out of the way, compact things, transport them or to heat them up for welding plus some cutting applications.Considering the variety one might wonder why no one tries it for "difficult" materials.Machined surface can be found throughout ancient history.Finding "machined things" were vibrations was clearly used is a bit harder.The great walls are not a perfect example here as the views differ quite a bit on how they could have been created.But if we leave things melting them or a secret concret like recipe for creating for example granite then vibrations start to make some sense.You find some interesting videos on youtube where people use speakers, wires and rocks to confirm you can actually "machine" them by vibrations.Especially granite has some quite musical properties, big boulders as well as smaller ones produce destinct sounds when you hit them hard.Tests and measurements were made on granite and other hard rocks to check how fast sound travels in them , how it is refeclted and where the sound comes out or affects the surface the most.Lets just say every sample gave different results.Shape, density and dimensions affect not just the resonant frequency but also where and how the sound travels in the rock.What if??We can use a simple speaker, a plate and some rice to see how patterns form under various frequencies.Works with sand or other granules as well.The interesting patterns are the so called harmoncis.Here we see clear and destinct patters, sometimes with extremely fine lines and areas of softly vibrating granules.Some people say these harmonic frequencies have all special meanings and uses.We mainly used them to avoid problems.Imagine your new TV would not have a housing tested to be stable with all frequencies the speakers can produce.All of a sudden your back of the TV might start to rattle ;)Same for car engines.Harmonic vibrations are eliminated wherever possible.Otherwise they could multiply and affect other things in the engine or around it.Simply put it means we have various options to detect and measure vibrations on a surface or in a system.Back in the day every half decent backup generator had a mechanical indicator for the frequency of the supplied electricity.A set of tiny forks with the desired on painted red and several on either side of it.These forks were designed to get into harmonic and therfor quite intense vibrations at their set frequency.If the one for 50Hz looked blurry then all was good ;)The same principle god be applied on a big boulder of granite.Place the "vibration meter" at the desired spot and start moving around the vibration source on the surface until you find a spot that causes maximum response on the meter.Best thing here is that if you then place that surface area onto another peice of fixed in place granite both pieces will start to loose substance if vibrations are applied.The fine sediment forming is then usable as an indicator where to move the vibration source to continue once the effect literally wears off.Is it feasable?Well, if we trust mainstream science then the answer is no.A huge amount of vibration energy would be required for such a hard material, despite ancient proof that says otherwise.Semi industrial test also seemed to confirm the theory as only with very high amplitudes (loudness) and while automatically adjusting for the resonant frequency changes a measurable amount of material was removed.I struggle a bit with that as for the testing tool heads made from hardened steel or carbide were used.And that with little or no regards on how the head and tool itself affects the output.I mean in terms of having the max possible movement happening right t the tool contact surface!There is a huge difference between applying a vibration to a tool and using a system, tool and tool head DESIGNED to work at the desired frequency!Otherwise we wouldn't need a computer to design and test a horn for welding purposes or shade a knife spefically so that the vibration go along the right axis and in the right direction.You not break a hard thing with a very soft thing unless it travels fast enough to become harder as the target!This complicated explanation basically just confirms that if you hit water at a too high speed then it will just break you into pieces instead of offering a soft splashPlease do not jump of bridges or such to confirm this yourself!!If that is really true and science says it is, then how about the other way around?Works fine too, or we wouldn't have pressure washers or water cutters.Now for the part where I hope some really smart people leave helpful comments:If we can cut steel with just a stream of water, then I ask:Isn't for example copper much harder than water?Steel is much harder than copper but water cuts through it.The answer here it simple or complicated, depending on how you want to expain how it works.Comes down to speed and pressure plus the right nozzle shape to prevent a beam expansion.But then water is indeed "harder than steel".Questions:Lets say we would use a copper pipe that in lenght, thickness, hardness and diameter is optimised to transmit a frequency so the pipe end sees the max vibration like a feed horn for ultrasonic welding.Not to hard to calculate these days :)Now imagine said "main frequency" would be optimised for the pipe but also be a harmonic frequency of the rock to be worked on.The pipe end would deform quickly, abrasion does the rest and it fails before even making a decent sratch that is not copper metal on granite.No matter how hard we press nothing good enough will ever happen.BUT: If we would add more hormainc frequencies to feed our pipe we can multiply the amplitude quite easy!Just try with a sound generator from your app store, needs 2 or more channels to be usable.Pick for example 400hZ on one and 800Hz on another, then finetune around these number to hear how the tone changes ;)My theory goes like this:If all "working frequencies" would just harmonics of the resonant frequency of the granite, then they can be tuned so the effect on the pipe end is minimised.The overlaying frequencies however should result in the same effect a water cutter has: The pipe becomes ultra hard.The better the match and the more you have to get it right the harder the pipe will be.Adding now a "drilling frequency" or multiple could be used to drive these harmonics slightly out of phase.Like with the sound generator on your phone we end up with a pulsating sound, or vibration.While the pipe still vibrates at the same "hardening" mix the drilling frequency creates a peak like a jackhammer.Try it by using the heaphone output on a small speaker and placing some light and tiny things into the cone.The will violently jump around during these pulsing tones.For a drilling system the output can be mechanically maximised by utilising a pitchfork design.A head holds the vibration speakers and the tynes are tuned good enough to the frequency of the speakers.Always two would have to operate in sync though as otherwise the pitchfork movement that transfers the sound down the center bar won't work.This head could then be desgined to act as a holder for a quick change of work out pipes that are no longer long enough for tuning.I guesstimate that a well tuned design would result in a copper pipe being able to drill at least 10 to 15cm into solid granite before it wears off too much.And we are talking here about just a few mm to get the thing out of tune!But would dare to desing such a thing just to confirm a theory that no one ever really dared to test? ;)And if friction welding works as good as ultrasonic welding, then what would happen if we try this with the right frequencies and vibrations instead of wasting tons of energy?

A little magnet experiment for everyone!

Some people just love to play with magnets and have a lot of them.If you are just like that and like to tinker a bit then I might have something for you.What magnets you use for the following experiment does not really matter but you should have 20 or 30 of identical properties.Can be disk magnets, block magnets or cubes, just not spheres ;)If you have a 3D printer you use it to make it fancy but a peice of wood, acrylic or such and a drill will do for round magnets.For cubes or flat packs you can make retaining walls on a flat surface.The experiment goes like this:I assume you already tried ways to combine your magnets to make them stronger, like stacking them up.But there is another way to really increase how strong they are combined.Start with one magnet at the center.Then like a ring add more magnets around it but with the oppisite side up.The created mounting solution is to prevent them flipping up and together, you want them as close as possible though.Add another ring and change the direction of the field again.Try this magnet, once all magnets are secured and compare the holding strenght to any other combo you tried so far.It will be much higher for the same amount of magnets.If you want to prevent the use of glue then try to create your mounting system with a really flat but strong enough bottom - this will then be the contact surface.Slightly reduced strength but you can re-use magnet with ease.But if you want to get a really strong one you need cube magnets.Like before you want to create some sort of grid, this time we go for a square.Start with cube in the center, facing north up.Leave enough space in your construction to add 8 more cubes around it - like on the face of a rubik's cube.Leave them empty for now !Add nother row, this time 16 to keep the square.Of course these one go with the south side facing up!Again one empty of 48 and then one last one with north side up with 196 magnets.Ok, to be fair, you wouldn't be able to pull it off a metal surface unless you used really tiny cubes, so if in doubt then go for just to 48 and leave the enter one out for now.Should be quite intense but similar to what any other shaped magnet would have done.Time to fill the voids!Add the cubes in the spce between the magnets so the north and south side face the magnets next to it!So basically sideways but in the correct orientation.You can then also add the center piece - try either orientation for that one ;)What happened now is that you forced the magnetic field lines to go up instead od for trying to go the easiest and shortest way to the next magnet.And "up" is where our magnetic surface would be, which provides the now overdue shortcut for the magnetic fields.Be amased how much stronger this version is and how much even 3x3x3 cubes would accomplish.With 10x10x10mm N52 magnets you might be able to use them support our wieght if you pull straight dwon from a horizontal surface...Ok, kidding, not just might, unless you are really big...One 10x10x10 might hold about 6kg.Stacked up a bit more but having 20 or stcked up would not be much stronger than 10.Even just 25 magnets with one in the center, one row of sideways orientated and one row with opposing field to the center one would be hard to remove from a steel surface.If we go with the imagined 6kg per magnet we could assume to get 25 x 6 = 150kg of holding power.Check you single magnet first then compare to the square of 25 ;)Consider using some plastic between magnet and surface so you can at least slide or pry it off if you have to.You can also combine magnets or a new one that has one side appear much stronger than the other.Meaning that for example on the north side it could hold 20kg while on the south side only 5.

The Newman Motor Challenge !

I was recently approached by someone claiming the old Newman Motor wouldn't be good for anything.Well, I was a little bit offended by this as I already had my little toy version of it as kid.At that time though it really was just a toy for me.Critics still say the Newman Motor is nothing more than some interesting machine.And even the biggest followers will admit it is not a free energy machine, just a very efficient one.I experimented with, what some call fringe science, now for about 30 years.And it all started with math and my interest in unusual ways of dealing with problems.So what's behind the challenge?The original design was suprisingly simple as you can see in the above Wiki link.Just a spinning magnet in a (split) coil.What you don't find anywhere though is real details on the how to.Sure, you need to have some sort of contact linked to the rotation and timing is critical but what does it all do?You can build a drt simple model in a few hours with stuff you might have around already.Quite a few Youtubers are happy to share their creations.The actual challenge is to come up with what Newman really did inside his drum.And also why I think it is not the full potential his machine had.Build a simple Newman motor and check for how long you can let it run on a charge super capacitor.Then sit back and read some of the other magnet stuff I wrote.After that come up with a better design ;)I started to create some 3D models that need testing once I find more free time - should take some leave one day..But for those with little patience and an interest in the Newman Motor I decided to share my current idea:For some it might be really confusing although they know motors and magnetic fields.Those just playing with magnets might have it easier for once as they can pretend they followed my thoughts ;)The original design used two coils and a rotating magnet.If you consider how the magnet creates an electromagntic field in the coils then you have to wonder right away how it can spin.And most designs will indeed need a push start to get going!You can't have electricity produced without the magnet spinning and you can't make it spin without electricity!The current from the battery or capacitor can only flow at the short moment of contact on the axle.This moment needs to be timed "mechanical" as we don't want to waste any power on not required electronics.If you ever bothered to check the timing of a Newman Motor then you realised the collapsing electromagnetic field at the moment of contact actually is in reverse to what the manget has in that position.Unlike any normal motor it means the magnet produces most of the power the coil needs to make the rotor spin!So far for the well known facts, now for my fiction:I would like to call my version the Aussie Newman Motor as all things downunder are just different ;)Here are my current desing mods, that I freely share so everyone can benefit form many years of experimenting to save a lot of time.1. Instead of two coils a not-really-bifilar coil is centered on the axle.The coil is created like two stacked relay coild that have no bobbin and a "dint" to allow the axle to pass through.Without the big gap of the original less of the magnetic field strenght is lost and the coil is far closer to a homogenous magnet.2. The timing done by salvaging a simple DC motor's contacts and brushes.This allows for far higher currents and if the salvaged motor had enough poles also for a very short "burst".3. The axle contact is made with a cleaned steel bearing.After cleaning very conductive copper based lubricant is used in tiny amounts to prevent corrosion and provide a lower resistance.The clear benefit is that with the new timing system a lot more current can flow.Initial tests with a mock up model showed an increase in run time from the capacitor of about 15% already.With proper bearings and a salvaged DC motor I hope to reach 18 to 20% more than the original design.Now why the DC motor if a reed contact or hall effect sensor would be even faster and with less resistence?Neither can handle really high currents without additional electronics ;)Plus of course I wanted to leave the door open for the Aussie Newman Motor 2020.You might now say "Why bother if the above improvements are already so great?".If you followed my elsewhere for a while then you know the Newman Motor is only 2D but I prefer 3D or more harmony if you like.Right now the imagination of people re-inventing Newman's machine is limited.They try to get on the horse from behind - literally.Fancy electronics, machined parts and so on.But they never go 3D ;)You got it? :)There is only two coils!!The magnet rotates, same as the contact on the axle.One set of coils for each contact the salvaged DC motor has.Each set aligend to the corresponding contact.And now you will ask "How do you plan to connect that to a single DC power source?Well, that is why it will be the 2020 model - my time for tinkering is sadly limited because I still need to work to support myself.But if you consider that the original as a good model can run for over 10 minutes on a supercapcitor then ask yourself how long it could run on 4 or even 8 coil sets.And although there is no such thing as "free energy": There will be still space for more coils.Or other coils to just provide electricity that does not power the motor.Critics will now see their chance and state that if we add a load to these additional coils then this will cause a strain on the system.Of course they are correct here.If, however, the load is mechanical then the motor needs to supply basically the same additional energy.Plus all mechanical losses.The question is: How much mechanical load can we add before the motor is down to the same efficiency of a very efficient DC motor? ;)And what if our Aussie Newman 2020 would actually violate the laws of physics?We can calculate how much electrical energy would be required so a given motor produces a fixed amount of torque.Or we can just measure it, the beauty of science...We can do the same in reverse of course.Let's say a mechanical pump would require 500RPM and 100Nm of torque to pump 100 liters per minute.Then we could calculate what sized motor we need to drive the thing and how much power the motor would need.So again: What if the Aussie Newman 2020 would require far less than what science makes us think and still does this job on a simple 12V lead acid batty of 4Ah?Just saying... ;)I hope to have a presentable and working 2 coil system by May, so stay tuned!In case you are faster or even beter then of course feel free to show off your results or to post a link to your Instructable so everyone can verify it.

Cannot post comments or reply to questions

When I tried yesterday to post a comment, it displayed a message: " Oops, something went wrong! " Today, I tried to reply to someone's question, but it wouldn't work: " Oops, something went wrong! " He was able to post the question, but that was eight days ago. That means this glitch happened between now and then.
