LIGHTcube by Attestor Forensics is a modular light system with individually combinable and scalable modules. Each module features one particular wavelength and can be controlled (on/off and dimming) via a membrane panel. A plurality of light pipes (32) are disposed to extend through the body into the interior of the cavity, so that the light pipes (32) carry light from inside to outside the cavity. The cube is made up of four layers, each containing 16 LEDs arranged in a 4x4 grid. expansion board(needs 20 I/Os to control). For increased versatility and budget economy LIGHTcube s can be scaled. ICSTATION 4x4x4 Light Cube kit uses 64 cuboid LED, and controlled by Arduino. You cannot make a perfect tower without these.
