RGB Lamp bulb replacement

Wanting to make some unique and interesting gifts for his nieces as well as improve his PCB skills and expand beyond Arduino, [Jay] has made these color changing Ikea lamps. He’s using an ATTiny2313 for the brains, a handful of RGB LEDs plus 3 warm white LEDs to keep the wife happy. you can download the schematic and PCB files if you want to reproduce this one yourself. You can see his PCB making skills have improved since the nursery room temperature monitor. We think his nieces will be pleased with their gifts.

Why is every post with a microchip tagged as an “arduino hack”? This has as much to do with arduino as it does with Lego Mindstorms. I don’t understand HAD’s fetishism with arduino.
This is a WONDERFUL microcontroller project! I especially appreciate the nice, large schematic image. I’m curious – why is the ATTiny2313 is utilizing the external 20MHz crystal? Even with PWM, I wouldn’t imagine this board requires time-critical processing. Using the on-chip RC oscillator might have saved a few components. Maybe I’m missing something though. Love the SMT board. Great work!
