thoughts on spinners
seaner:
I'm going about constructing a spinner... has anyone had any luck using the encoders from a standard PC mouse on such a thing?
I've got the knob machined out of aluminum, and it looks snappy, just trying to figure out what to do about encoding.
My options are basically the following:
1. mount encoder wheel from mouse, keeping the photodiodes in the same locations on the original PCB.
2. print out a larger encoder wheel with custom spacing on laser printer transparency, sandwich between plexiglass discs, and remount the photodiodes (in pairs, since the gap spacing will have changed) on a new PCB.
Any thoughts?

if anyone cares to read more on my progress.
Cheers,

Some people have used the encoder wheels from their mice. I believe the Twisty-Grip plans use the encoders.
I cut my own encoder from a thin sheet of styrene. I printed the encoder wheels from the Cheep Spinner plans and glued them to the styrene, and then cut the wheel out using an exacto knife.
Brad Lee:
I bought the seperate parts(encoder wheel and optics) from Oscar's for a grand total of like 15bucks, including shipping
A little bit more than printing/making your own discs once you factor time into it, yet a heck of a lot more reasonable than getting a whole spinner rig, even the cheap ones from Oscar are what, 40bucks?
(I havent checked prices in a while)
Justin:
Brad, where did you get these parts exactly? :-\

I'm no brad.. but he's referring to OSCAR from http://www.oscarcontrols.com

EDIT/PS Have you checked out the usable suspects for great howto's on building your own spinner from scratch? (i.e. cheep spinner, twistygrip, hardrive spinner, and uhm... one other...) i've got the pdf plans to those somewhere if you need 'em... *Shrug*
