Reply to Need helt finding/making a high res. encoder

Hi!

I need to find a high resolution encoder to try some stuff out for my project. The problem I have is the ones I find are either to expensive or to tall to fit in my case.

Been believeing about making my own with photointerruptors and a code disc however it would still be hard to get the resolution I'm after.

I would like to achieve at least 1000+ klicks per revolution and if possible double that. I remember that extraclassig used the photointerruptors from an old exponent a while back and made his own code disc. Does anyone know how that turned out? Or what resolution he ended up with.

I'm a little stuck on this one, so any advice is greatly appreciated.

Been believeing about a multi level code disc, perhaps even one with absolute position to help avoiding bad readings. Let me know what you believe. Could this work or is it a silly idea?

Cheers
