  • As I've uploaded the PCB layout files to batchpcb (sparkfun), I could send you a PM with the link. Making your own from scratch will be much more rewarding though (in the end, after a few setbacks maybe).

  • The LEDs are directly powered by the microcontroller (ATmega168-20AU) using current limiting resistors in the range of 90-110Ω, but the exact values depend on the kind of LED of course. I use the "moderndevice" BUB for programming. When I need them in stand alone mode, I use a step-up converter to get 5V from 2x AA cells. It uses the MAX756 chip and just a few other components. The circuit comes 1:1 from the datasheet. Adafruit used these in "MintyBoost" REV1 I think. Works OK.

  • See my last comment. It's all on my blog ;-)

  • kool :) i want one XD

  • Make one !

  • @zupnikal I dont have that board or chip XD or LEDs XD

    i got some common anode rgb LEDs tho :(

  • I have 2 unpopulated boards left. BatchPCB sent me a few more than I had ordered.

    If you want them:

    6€ per board + shipping ;-)

    Board + all parts: 14€ + shipping.

  • so board and parts would be about $20 ish (i dont work in €'s XD its either £ $ or Nok :P mainly $ tho cos of thats wat i get in my paypal..)

  • Yup.
