Hello, i had a similar idea to use a magnification glass of 80 or better 100mm, but istead of the sun i thought would suggest a hologen lamp of 500-1000W this way you are independend from the sun and its easier.
Hello batcrave, i like the look but not the price :) i read your answer and want to share my ideas.the tubes:to reproduce the exact same glowing effect you could use a hollow plexi-glass tube and coat it inside with glue+ "fluorescent Luminous Glow in the Dark powder"(1 bag is 10 grams for 1$ enough for several tubes on ebay)then attach a UV-Led(400nm cheap around 10-20pcs ~1-2$) to fit inside the tube.(1 led per tube so 8 are needed)The build can be done with several types of leds depending on your desired size5mm , / 3mm or a 1206/805-smd Led If you select the plexiglas tube (pmma/acrylic) to fit the led size its practical.Last step is the electronics, which can be as easy as a 1 resistor only :Dor a PWM circuit with smd components (555timer for example). The last part is th...

The last part is the powersource, which can be stored in the middle (that little cube in the center).For small builds a possible power source would be 2 silver oxide batteries in stacked parallelhttps://en.wikipedia.org/wiki/Silver-oxide_batterythey can last very long if you take only 1 milliampere per Led With a pwm circuit this current could be reduced by the factor of 10-20If you make the Build slightly bigger other batterytypes cloud be used too like 2 small lithium polymere batters from (~1nche sqaure size)Another idea is you could store AAA(micro batteries) inside the outer frame tubesso there is a huge powersource of 8-12 AAA-Batteries xDor even better i found https://en.wikipedia.org/wiki/AAAA_batterythey aren't much more expensive on ebay. but thinner in diameterthen the light tubes can also be bigger in diameter so its design looks harmonic.let me know what you think of my suggestions. :
this looks interesting but for what kind of research is this? biohazard? chemicals? ccancerous dust-producing work?
haha reminded me instantly of a hybrid between the SAW-Movie-doll and Avatar-Aliens :D
yes i agree it does not seem a good idea for long term use. i suggest a better idea: you can try the skull to "hear" (behind the ear for example) vibrations.
hello, can you make it faster like 10000 or 20000 rpm ?if not , why only 1440 rpm?
well i use it as a tool and not for food related tasks since there is a controversy that it is a potential health risk. https://en.wikipedia.org/wiki/Aluminium#Health_con...I mean why to risk your health with no reward to win ;),the same is with teflon, good for tools but not for food. Some people trust authorities to the point they would eat aluminium foil just to "proove" the "conspiracy folks" wrong ;) . But the trackrecord of the authorities dont suggest them as a trustworthy party (corruption..). The difficulty is that aluminium might be a long term and not a short term poison , so we will scientific see results in the next 50 years.
interesting but not special enough, do something apps cant do for example use a second module to build a wifi triangulation radar, add add magnetometer or/and gyro module to have a radial refernce point in the code. greetings
cool project , just use 2 big (rear) Motorcross wheel istead
can you explain the software part please, how does the know gets installed in windows?
i dont understand it, i know you need to etch copper and a stencil mask. But why is your copper coloered blue? so you use 3 masks?

1000x usb microscope costs 12,48$ http://www.ebay.com/itm/2MP-1000X-8LED-USB-Portabl...
great question i am curios too
its a common ebay.com microscope, cost is a bout 30$ directly from china, maybe some local sellers have a similar price. Beware that nearly all china microscopes arent HD but interpolated VGA. But it does not mean they arent useful. Just dont pay too much for it.
at Step9 you are using a brass adapter to couple the bigger Banheater to a smaller pipe? can you describe the dimensions please
I use a cheap 3$ Webcam with manual fixfocus objectives. The can changed to an extreme near focus ( approx 1cm) so you have a fullsreen view of electronices
build a 3D Printer first :D , its way cheaper than buying if you have a bit of practice skills. Tutorials are tons on youtube. On the Otherhand PVC + Paint + a Dremel could produce a similar outcome :).
you can start a new business like the Bangbus guys did :D
The machine looks like from a dystopian sci-fi movie :D .
you can add a 3D-Printerhead(extruder) to your cnc , download the model from thingyverse or similar sites and build the shoes for yourself with ninjaflex ;)
Yes i know. But it was too funny, so i had to write it. :)
Haha , remember how milk smells after some days? and then use this package as air conditioner xD
maybe You could use an Heatairgun with temperature control . They can Reach 450-700 Degrees Celsius depending on the Model.
this is great and i have an idea to cut the cost even more with the same funtionality by 60% ! .You can use a Drawer slider (~3,65$) and glue a small plastic or metal Ruler on its side (cost some 0,50 - 1,00$ idk)
too dangerous, add more warnings to your text. Some people got hurt with similar devices, and i read a lot of 13 olds build this thing.
