I have now got it running, I ended up buying a sensor from erik (on this list). I did not notice any "holes" in my disc so I just monitor the disc edge. seems to work great and positioning was not a problem.

(*Way* too fast for my taste...) That's what I did on my meter, but: * finding a phototransistor sensible to red light is not that easy (most are sensible to infrared) * I added a red diode to report the blinks from the watched diode * I didn't design the sensitivity circuit carefully, and finally had to cover the whole meter in a black box, because even with electric lights on, the ambient light level was so high that the red blink was not noticed (repeater diode always on) -- NH ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
