Open hardware Moodlamp with ATmega

[Daniel Andrade] has built a pretty cool mood lamp circuit. He was initially inspired by [Toon Beerton's] Ikea lamp, but found he just didn’t have the knowledge to proceed with the PIC processor. He rushed out and bought an arduino to begin learning. Once he figured out how to properly make a mood lamp function, he created a custom circuit to utilize an ATmega chip instead of his whole arduino.  He’s now on his second revision of the circuit and is sharing all the files with whoever would like to download them.

His circuit utilizes a 3wRGB LED and any ATmega 8/168/328. He has left some space for expansion on the board as well just in case you’d like to add sensors of some kind (he mentions a temp sensor).

 

DIY mood lamp looks store-bought

[NeZoomie] built an RGB mood lamp as his first electronics project. He certainly hit it out of the park with this one, ending up with a design so clean it could be a commercial product. The controller is an Arduino board (further proof that this is a fantastic entry-level platform) that interfaces with 8 RGB LEDs. He’s built an enclosure out of thick polypropylene that does a great job of diffusing the light and adding a stylish look. The control system features a rotary potentiometer from SparkFun and what he calls a tilt-potentiometer of his own design after drawing inspiration from Hack a Day.

Blinky things are fun and that’s why we see a lot of mood lamps around here. Take a look at the video after the break and if you’ve got the parts, give this one a try!
