Hey guys!
I'm going to build a heavy duty ultrasonic cleaner. I've got a little 35w consumer one (that I don't believe actually does 35 watts) for watches and jewelry and small things like that, but it's too small, underpowered, and cheap... I want one that I can drop a carburetor or a brake caliper in and buzz the gunk out of it.
I'd like to build a 100w one that either energizes water in a large stainless dog food bowl or a stock pot if I can find a thin walled one. They sell the transducers and power supplies online, so that part will be easy. I've also got a design in mind for the enclosure and a cooling fan... What I need help designing is the timer. Units that I'm looking at have a 50% duty cycle and should be on for 5 minutes and off for 5 minutes before using again.
Does anybody make a project board or modular controller for things like this? It would be nice to just drop in a pre-made module that could turn the power on and off without me having to do it manually. If there isn't something like that already available, maybe it would be a good mini Arduino project?

Reviving an old thread.
I've got the layout for the electronics mostly finished. I have to design the enclosure to fit around it next.
I need to figure out what type of connector to use to go between the power unit and the wash chamber. What kind of connector would you use to mount through the box I'm designing? I've got some Radio Shack Molex connector laying around, but I don't think they're very well suited to panel/bulkhead mounting.

That is the 4 position panel mount side. I have the 4 position plug side and pins for both if you want to just pick a couple up. Or if your not in a real hurry I can add them to my next Mouser Order.
Some things are meant to be closed. Your mind isn't one of them.

Not sure about the voltage... This is to connect the transducer to the output of the driver board, and that's an unknown quantity. It gets fed straight mains current, rectifies it to ?.? voltage, which juices an oscillator feeding a pair of transistors with heatsinks connected to an output transformer.
I'll let you know about a Mouser order. I don't remember how bad it is shipping small quantities from them... Might check Amazon first.
