Cheap Chinese Ultrasonic Cleaner - Part Three

[IntheGroove]

I have several of those up to 10 liters. I use them all day everyday. I had one fail so I bought another of the same size to figure out what components on the circuit
board that needed replacement. Fixed that one and have had no more problems...

The piezo transducers and driver boards are basically jellybean at this point on AliExpress. I was doing a high power 40kHz project a while ago and this was by far the cheapest source of ultrasonic gear. You can get a whole piezo and tuned horn for like $10. It's crazy.
