The standard model TV-B-Gone consists of an infra-red LED, two CR2032 cells and an integrated circuit containing the television power code database, all in a plastic case.
It is considerably more powerful than the standard model, using eight infra-red LEDs to allow TVs to be turned off from distances of up to 100 meters (300 feet).
Instead of disguising it as an iPhone, Mitch Altman has made the new and improved TV-B-Gone look like an iPod Nano and go ten more yards than the old one.
At several hacker conventions Mitch Altman has run workshops that allow participants to build their own TV-B-Gones using Adafruit Industries' micro controller–based mini-POV kit.
