Based on a Trust PS/2 Mouse I build this computer mouse for one of my Steampunk computers.
Building a mouse is a bit tricky but see the results and the steps hoe I build it.
Step 1: The mouse
I disassembled the mouse and covered the PCB with a piece of leather.
Then I covered the wheel with a gear and a piece of a copper tube.
I used glue to fasten it.
The cables where covered by shoelaces. I slitted the ends of the cables into the four wires and covered them with shoelace as well.
