Decent MAME Spinner?

For my hard drive hack spinner I used the encoder wheel from the mouse I hacked and it seems to be great...  The mouse I used is similar to this:

For the knob I used half a yo-yo.

Who manufactured this "supermarket mouse" that you recommend?

It was an ASDA own brand one.... but that was over 12 months ago, so you may not find the exact same mouse in there now.

The best bet is to try a few cheap mice to see what works out.

Was the PCB labeled? Do you have links or pics of your spinners?

On second thought - I bet they make the wheels larger so they will have more rotations per knob twist. A large encoder wheel will move a greater distance per knob twist than a smaller encoder wheel.

The only difference I could think of is the size of the teeth. Maybe old fashioned optics could not make out the tiny teeth used in mouse optics. The speed with wich the teeth move past the optics would be the same if you have a large or small wheel. Well maybe not the speed, but the timing of the pulses would be the same (if you keep the same number of teeth).
