Tom’s RGB mood lamp


[Tom] has been refining a board that drives a high power RGB LED for applications like this moodlight. It’s based around an ATmega8 microcontroller. The goal was to make an RGB LED easy to work with: It can cycle between colors in standalone mode. You can control it via a serial interface. It also has a pin header to hooking up three potentiometers for manual color mixing. Boards aren’t available yet, but he’s already posted a build tutorial. The board looks straightforward enough that it shouldn’t be too hard to layout if you really want to.

RGB etched box


[Dine909] brings us this simple glowing box made out of five etched PCBs. The PCBs control RGB LEDs inside the box, which is also filled with clear glass beads. The four walls are connected to a base controller board that has a Cypress PSoC chip for color mixing. There’s no writeup, and even though it looks a lot like the Lament Configuration, it should be a lot easier to build; any transportation to other dimensions it provides will be strictly figurative.
