I'm going to build a very basic ultrasonic cleaning tank based on a
555 and using a piezoelectric tweeter (which I will probably have to waterproof somehow).I live in San Diego, CA, and welcome any suggestions for a reliable parts supplier, either local or on the Web.
Anybody 'less expensive' than Radio Shack? (I read an NG comment that they have such tweeters for around $5, but have found piezo tweeters for about $3.80 on the net and, since I am temporarily on disability [ get this: black widow spider bite, siezure, dislocated shoulder, two operations! ], cost is a concern.
