The ZephIR (pronounced zeffer) is a device which connects to a computer through a USB port. It enables the computer to generate infrared(IR) signals which will control almost any piece of equipment designed for infrared remote control. It can control DVD players, receivers, VCRs, satellite boxes, cableboxes, children's toys, televisions, and a host of other equipment. It comes with its own software and looks like a tiny black box with little LEDs on the front of it and a USB cable hooked to it. It is completely USB powered and requires no batteries or wall warts.
