This LED lamp, which uses a soda cup as a lampshade, is Internet enabled thanks to a Linux board (translated). To say the system is overpowered would be a gross understatement. But at least there’s plenty of room for growth.
The lamp is really just a hardware extension for the Linux board. A half-dozen colored LEDs are driven by an ATmega8 and a few transistors. A Fox LX832 board pushes color instructions to the microcontroller via the i2c protocol. [Gibus] chose this board because it has a built-in Ethernet port which makes it perfect for communicating via a smart phone browser. This is where the majority of the work on the project happened. He coded a Flash application that lets you select color, hue, and saturation data from any device that doesn’t run iOS. These commands are processed by a C application running on the Linux board. See a demo of the web app, and the resulting color changes in the clip after the break.
