This rather bulky looking wall wart is actually a computer mouse. Sure, it may cause your hand to cramp horribly if used for any length of time. But some would say it’s worth that for the hipster value of the thing.
The rather odd shape is somewhat explained by the fact that this was sourced from Ikea. After gutting the transformer found inside the plastic case he had plenty of room to work with. He drilled a hole so that the sensor from a Logitech USB optical mouse can pick up the movement of the mouse. He also got pretty creative when it came to the buttons. The two prongs of the wall plug pivot horizontally to affect the momentary press switches inside.
After the break you can see a quick demo of the project. [Alec] doesn’t consider it to be complete. He wants to make a couple of improvements which include adding weight to make it feel more like the original wall wart, and finding a way to hide the hole he drilled for the sensor.
