To kill a mouse

I have seen that one may use a little slotted wheel from a mouse to encode the shaft of motors as a speed or position indicator.
Other than the obvious -- Do use an optical mouse.· Are there any particulars.
I really hated cleaning the litte guys before I got my optical, so I wanna chop some.

I took apart a mouse and removed the two 'encoder' wheels.
They use a LED and a photo transistor to create a pulsed output.
I found that I could salvage these also, by gently cutting up the circuit with a hacksaw.
So now I have two encoders and two sets of LED/phototransistors that I can add to two motor shafts.
The 'encoder' are merely slotted [noparse][[/noparse]no quadriture] so I think that they might work best with a H-bridge and matching or measureing velocities.
What is left? I have to reverse enginner the photo-transistors and LEDs (these are the very tiny kind of LEDs) to figure out how to power them.
All in all it seems very sucessful.
