I say something about an electric harmonica based on the
old wurlitzer electric piano tech.
Anybody know how this is coming along.

It's on "Instructibles.com". The guy was only able to get it to work by detaching the reeds, putting in a plastic washer as an insulator, and then shaving down the sides of the reeds so there was no possibility for a "saliva bridge" to short the circuit. I tried to replicate it using some other ideas from old patents (do a google patent search on "electrostatic pickup for harmonica"), but I couldn't get a working prototype.
It really bumbed me out that I couldn't make it work, actually, cause I think it would be a great cheap solution to make an amped up harp that is not susceptible to feedback. I guess there is a reason why TurboDog's laser based system is the leading modern version of this idea!

I bought some components this week to play around with this (wierd that you brought it up). It would be a fair bit of effort but i was thinking I could replace the reed plate with something non-conductive, and mount a brass strip on the coverplates as a ground plate instead of using the reedplates.
Instructable is here:

Isaac I'd be interested to hear more details about how you went with it or if yo have any ideas.
Also does anyone have any suggestions for a pre-amp circuit? Or a good material to cut reed plates from?
