I really appreciate your input. This is extremely helpful. I also picked up some epoxy this afternoon to do exactly what you said. I realize the Arduino is overkill, but I'm complete newbie and it seemed like the quickest solution. Whenever my next revision is ready, can I send you an email?

Yes, please send me email. I find this project very interesting and you've done a great job documenting it. I'm going to order some Hall effect sensors and see what results I get with them. I'll let you know what I find out. Also, be careful with the epoxy. You need to get some specific kind (that is non-conductive), and I'm not sure what that is. There are all sorts of effects materials have on electronics; the epoxy could add resistance, capacitance, inductance, and any of those could adversely affect your circuit. Hopefully you can get specific advice from someone more qualified than I am.
