Luminch One is an interactive lamp controlled by the movements of your hand. Wave your hand over it to turn it on or off, or move your hand up or down above it to change its brightness. Inside the lamp, an Arduino hooked to an infrared distance sensor tracks your hand and sets the state and the brightness of the LED lamp.
Francisco walks you through the process of building your own, complete with the source code and great diagrams and photos. Finished off with a paper craft shade, the Luminch One has a contemporary style that would perfectly complement a modern home.
