Take power from a PC with this handy USB lead. The lead is 1m long and has pre tinned red and black wires which connect to the 5V pins on the USB plug. The USB standard allows peripherals to draw 100mA each, which is plenty enough to power an LED or most simple circuits.

Build a computer desk lamp or ornament using this simple board. Available with either a white or colour changing LED the board takes power from a USB port. The kit includes a switch and the USB cable (described above).
