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.
