I like to improve myself and things I find :) Learning new things every day is next to impossible but I still try - only a working brain can work. I have no special sector to cover, electronics, electrical stuff, 3D printing, restoring old clocks and furniture. Whatever sounds interesting I try it. In my spare time I love to fly big kites, go fishing or simply go bush in 4WD to find a good fishing spot. Active spam fighter!

  • Downunder35m commented on ManosZ1's forum topic Arduino/ESP8266/servo noise when idle11 hours ago

    You're welcome!

    Well that explains some things...The Wifi stuff needs accurate timing, so it will be prefered over other things.In return the servo controls might get distorted or badly timed signals.Check the Arduino playground for options on how to control servo motors without the library you use and see if it improves on the problem.Better than buying new stuff if you ask me ;)

    You can try the "wire" used to hand down ceilings.Quite thick and really stiff but still possible to form hooks and loops if required.Another option are the "lines" of these cheap metal clothes dryers, you know the fold up ones...I salvage them sometimes to make fishing rod holders.

  • For the first I have no objections, second only seems to use a link to some software used for the PCB, not perfect but people do it.The last however is blatent money making as the author also used link encrypters that provide ads for money.

    It would be nice if someone from the dev team or support could look into this.Promoting something yu create is fine with me, but using money making link services to send people to their own online shop is just wrong!Same when something is posted by people related to the company to simply advertise a new product.Have to agree with the thread starter here.Instructables is about making but not about promoting your products to make money.Especially not if these companies enter contests with it, get featured!!! or otherwise promoted by Instructables.I would like see a clear statement here on the topic of company driven Instructables for monetary purposes.

    Can't agree.Hidden ads like this or Instructables posted just to promote your companies product/store it wrong!This website makes enough money by using their own ad system, we really should not tolerate Instructables with one purpose only and here it is money.But instead they get featured and more.... :(Flagged my comment above in the hope someone from the team wil speak up here and offer some explanations....

  • Driving a servo only requires the PWM pulse and the right amount of them.First I would check if you can use the servos with that library in some other code.Maybe something simple like flashing some random LED'S and after each run to make the servo go bit in defined steps.If that works it could mean the interupts used for the servos hav timing problem in your original code.Could be due to the rest being too CPU hungry.If that causes similar noise problems I would try a simple servo code from the Arduino playground just to see if the servos work fine with that.In case they do abandon the sparkfun library and try a different one.Last resort would be trying a different servo, but can't recommend any as I don't use them much.Writing your own routing to generate PWM pulses to drive the servo...

    I was only able to spin the wheel myself once on a casino grade roulette but from that I know they are really heavy.Would say about 20kg at least for the spinning part.If you use a tapered bearing like used in the hub of you cars wheels then it should work fine.On a smaller scale I wuld take a bicycle wheel with axle as a base for me work.Has a suitable diameter and the right type of bearings for a long spin.Plus ou have a stable mounting base for the rest of the wheel.Rest is math and angles.

    Even coolhouses use just styrofoarm sheets - simple polystyrene.An added layer of aluminium foil reflects the warm stuff on one side and the cold stuff keeps cold.PU foam does work too if you prefer to spray.A household freezer has about 4-6cm insulation in the tick parts and often only 2-3cm in the thinner parts while a coolhouse has at least 15cm.All you need is in a good warware store.

Heavy duty works.Here I use aluminium brazing or welding rods from the hardware store.Principle is same as above just that I use the rod directly for the scratching action and only assist with needle and brush.Tricky bit is that these rods are just a few degrees under the melting point of aluminium, so it takes care not to overheat the material.Whatever you do: never use a solder with a flux in it.

  • Not quite sure on your skill sets...You can get IR remotes for these cheap LED strips, good for 2A per channel and 12V.Some are basic, some with 3 user buttons for personal light settings.You could get or make a 3V power supply for the remote and use a fibre optics wire to get the light to your power supply with the controller.The face cover you would need to custom make to hold the remote and only leave the power and user buttons accessible.Other option would be to use some relays and fixed resistors to do the trick.Plus of course multiple wires running from the switches to the relays.A little Arduino and wifi modules could do the same and depending on your skills fully adjustable.

  • Downunder35m commented on nitrojon's forum topic Charging SLAs from DC3 weeks ago

    6.6 to 7.2V is a good value.But using just unregulated DC is not the best option to keep your battery fit.IMHO the best option would be to wast the 5 bucks and order a 6V solr battery charge controller from Fleabuy or similar.Connect the battery and the load plus you DC for charging, in this case it can be anything from aorund 8V to over 20V - so you might have a suitable supply collecting dust somewhere already.By using the controller you avoid the troubles of creating your own protection circuit, charge regulator and so on, will cost more if you buy the required parts than getting it as a whole from china ;)

  • It is sadly quite normal for (electronic) transformers in lighting systems to require a minimum load.Often as high as 40% of the max power rating.Anything that was designed for halogen lights for example.IMHO it is easier to get a laptop power supply, the old ones for 12V or one from an old monitor.They don't require a minimum load and provide 4A with ease if they have to.But by now every good hardware store should stock dedicated LED transformers in ther lights section.

  • You can use a RGB strip driver module.They are dirt cheap and come with a IR remote on Ebay.These provide a max output of 12V as they are meant for this voltage.Most can handle up to 2A per channel, so more than what you need.All YOU need as to add a suitable resistor to each color of your LED.The datasheet should tell you the pricese values for each color and you can use an online LED calculator (or your own) to get the right resistor value for 12V.Can't go much cheaper and easier....

    In case you struggle with the math:Assuming all colors have the same max then a 36 Ohm resistor with 5W should keep you safe.

  • Downunder35m commented on ambientvoid's forum topic sidecar wheel position1 month ago

    A sidecar construction usuallyonly has three wheels with one for steering.How do you want to keep it stable with two turning wheels?You change the center of the circle and the fulcrum point depending on the steering position...I don' see it working...On a normal sidecar the wheel is positioned to give maximum support while turning to the side the sidecar is mounted. Too far in the front and the backwheel lifts, too far in the back and the same happens, both mean a lot of damage to the bike and people involved.Also helps to know the weight distribution between front and rear wheel.

Load swing...If the board ever started shaking due to too high speeds, worn rubbers or whatever then the attached board often caused fatal instabilities.You want to create your pivot mechanism so it allows for a certain amount of freedom for your board.3. Vibrations...This was our actual problem back in the day.With really good connections everywhere and allnice and solid the laminated sections of the board were under too much stress.Sp only way out would have been to use a mounting plate right over the back axle but that would have made the board useless for any fun use.On a long board you certainly have more options an with modern glues it would even be possible to avoid drilling holes into the board.If you can tolerate it than I still think the back axle is the best connection point.And nothing against a sidecar but I think you find in the end that a longer connection between board and load and the load behind you makes life easier.
