Often I need to test a electrical component such as an LED and its always helpful to have a power supply with various voltages available. Some companies sell variable power supplies but for around $100 you only get 3 amps where using this computer power supply, I get 18 amps on the 12v rail and it only cost $20.

Being a fan of pong, I purchased one of Velleman’s solder it yourself project kits that lets you put together your own pong game. Once finished, it was fun to play but you don't get the same gameplay without a joystick controller. I ended up buying 3 project boxes, one for the main-board and two more for the controllers. I wired buttons and a power switch for the main-board and I made the controllers connect using rj45 cable/connectors. Overall the game is a lot more playable and much easier to transport.
