This is my homemade trackball made from two mouses. The first one is a optical mouse. It detects where the ball is. The second mouse holds the ball and operates the buttons.

    no, the opitical mouse senses the ball moving and moves the mouse. But the left and right is mixed up. So i use a mouse programs that flips it.

    As mice are low-power devices, you can match up the ps/2 and usb wires and solder them together. This would eliminate one cord, and allow for both devices to continue to work.
