This is my first attempt to create a persistence of vision (POV) display using the Arduino. The ultimate goal is to mount it on my bike wheel and have it display nice things while I ride. But, for now, it consist of an array of 6 LEDs mounted on a turning rig I made From scrap material.
Materials for the rig:
- 2 old cell phone batteries (found in the garbage) that serve as a counterweight
- A piece of metal (from an old photocopier) that constitutes the turning blade
- A fan motor from some sort of broken power supply I found in the UdeM garbage
- A piece of plastic that makes the base (also from the photocopier)
- A plastic poster edge (the things used to hold paper posters) that I found in the garbage (it is used to cover the sharp edges of the blade).
- A heavy metal block that stabilizes the contraption (since it tends to oscillate a bit when it’s turning)
- A cable with a switch from an IKEA lamp I found in the garbage
- Lots of cable ties
Materials for the POV circuit:
- A small breadboard (it came with an electronics magazine)
- 6 red high power LEDs
- 6 1 k Ohms resistors
- A 9V battery w/ battery older
I think the pictures are pretty self explanatory.
So far I have done some simple patterns for the display and I’ll upload the code soon (it still needs some polish)
