Ever spin a pencil under the eye of your optical mouse?

Great, now it's a holiday monday (canadian thanks giving) and I need to find something in my house that's junk, and has high speed bearings in it.  I hacked apart an old cordless drill which the batteries wouldn't charge (cheaper to buy an new drill than replacement batteries lol).... no bearings. 

I have an old $40 dvd player that never worked that they gave me when I bought my truck (cost of shipping for repairs was more than the value of the player)... it has a smooth spinning motor that spins the disks, but it's really fine.  Not sure if it would be tough enough to stand up to arcade play, or if I could attach stuff to it; and dammned if I have a jeweler's screwdriver small enough to get it out of the frame it's mounted in.

...hmmm me with no skateboards or junk hard drives.  Guess I'll have to wait until after the holiday.

Hi Mark70,

Not found any piccies yet but......

I mounted my mouse upside down so that the optical sensor was scanning the bearing directly.

The HD bearing is mounted in 1/2" MDF which is 11" by 4" as this is a modular panel that snaps in and out.

The beauty of this mounting method is that it reduces the number of parts required (simply screw it to the wood through the base putting some washers as spacers underneath the mouse to get the correct height), works great and provides easy hand held operation of the mouse buttons. I simply sellotaped the top of the mouse back onto the PCB and base.

Simple hand held operation if required with the mouse buttons within easy reach.

I will dig up some pictures for you.
