Formerly known as ARTS: Auto stereoscopic Rainbow glowing TechInc logo Steering wheel
Code
PCB layout and code for the LEDs
Things to make and do
This project has several parts: backlit the wheel, mount the wheel to the wall or on some stand, and make the wheel control something. It would be nice to be able to unmount the wheel and take it somewhere else, e.g. to display it at events like OHM.
Painting
Who: Narya
- NO color painting!
- I will fix the scratched parts with varnish
Backlit
Who: Narya, Brainsmoke and Mariejel
Hardware components
- 12V RGB LED strip (needs extra stuff to make it addressable)
- about 60 regular common anode RGB LEDs
- 60 WS2811 chips
- 5V RGB LED strip (addressable, needs more powerful adapter)
- Arduino (diecisomething and a nano)
- 12V and 5V adapter
- RGB LED arduino shield
Lesson 1: the 12V LEDs are not addressable
And now what?
- Cut current strip to even smaller pieces and buy WS2801's or WS2811's for every pixel you want to address. Or, use the current set-up in another project (space lighting or something like that, where you just have one colour for the entire thing, e.g. in combination with this color sensor, in house)
- There are also RGB LEDs (the regular type, not smd or part of a strip). Build one small board for every pixel. Takes a long time, but might be fun. (needs: WS2811/WS2801 chips, resistors, board)
- Use *addressable* RGB LEDs (WS2801 or WS2811). This is the easiest way to make it work. I currently have 30 LEDs of the WS2811 type at home. Maybe use these.
Next: learn how to make a PCB design
Software
- FastSPI library for driving led controllers on arduino based systems
- Take a look at: Neopixel library https://github.com/adafruit/Adafruit_NeoPixel
- Take a look at: ShiftPWM http://www.elcojacobs.com/using-shiftpwm-to-control-led-strips-with-arduino/

Design a few patterns for the wheel
- Info about colors on Wikipedia
- Make a plan for controlling the lights, ideas:
- No rotation: colors of logo
Rotation: full color SpokePOV (PimpMyBike blog)- based on comments: maybe not such a good idea, since wheel has to spin fast- From center to outside and vice versa
- Rotating colors
- ...
Mount
Who: justa, narya, control-k
- Location: on the wall - done
Control
Who: you?
Random ideas, feel free to add your ideas below and add your name if you like to work on it
Make something that registers when the wheel is turnedLet it control X when the wheel is turned (don't know what "X" should be, ideas are welcome)No function, just let it rotate- For now: no rotation
