Ultrasonic Cleaner Circuit

Posted on Nov 8, 2012

Ail ultrasonic cleaner is useful to clean certain items. This circuit uses a microcontroller to control timing and give a digital readout, but only the basic oscillator can be used, if desired. RESL, RES2 are piezoelectric transducers driven by power oscillator Ql. Ql is powered by a bridge rectifier-capacitor input filler that operates directly off the ac line.
