I just bought this thing: http://www.ohmguitars.com/

Apparently he has a special now where you can make an offer. Probably having a tough time selling them.

Very sturdy unit.

Hope you're not in a hurry to get it.........trust me, I know. Stay on him.

There's a link in that tutorial link to a .pdf that shows the wiring schematic for the sensor. Pair that with the part numbers I give in the first post and you'll be fine.

I made mine from a serger sewing machine, though I don't imagine it much matters what time of sewing machine you use. I just used it because it was free, and among the three free sewing machines I had, I liked the size (small). I stripped everything off of it that wasn't needed, cut a plastic disc to make the handwheel flat so that the bobbin could be mounted with double stick tape. I removed the foot speed control and added a dimmer switch in it's place. For a counter, I used a computer mouse, soldered wires to the left click contacts, grounded one to the machine, and secured the other one so that everytime the sewing machine foot raises it contacts the wire (one revolution). To use the counter, I just use the calculator on my laptop, hit 1+1 and =. Everytime it revolves it adds one to it. It can count faster than I'm capable of winding, so it has no problem keeping up. As a guide for the magnet wire, I used a rod that was a rail in a flatbed scanner I bought 12 years ago because it was nice and smooth and because I had it. I used two stop collars as limiters for the wire winding. I'll try and post a picture tomorrow.
