An ATTiny2313 powers this night light, driving multicolor LEDs diffused by ping-pong balls. nuumio writes:
Geir’s RGB night light was such an inspiration I just had to make my own. Instead of Picaxes I decided to use ATTiny 2313. At first I tried to program it with C but I ran to some “differences of opinions” with gcc when I tried to assign dedicated registers to variables holding duty cycle values (for speed optimizations). After some struggling I gave up and coded the whole thing in AVR assembly. I was quite surprised how easy it was after all. It took me about one weekend and I got first versions running nicely.
Great job, nuumio!
