Re: Ultrasonic Cleaner Schematic
Also, keep alert for industrial equipment auctions- many different industries use ultrasonic cleaners.
Again, if you find a source for components, let us know!

Re: Ultrasonic Cleaner Schematic
Tried that myself for cleaning gun parts. I found the DIY approach too expensive because the transducers in small quantity are spendy! $60+. Then you have the joy of matching inductors to the likes of Branson, or Crest units. To repair a 1 gallon unit with blown transducers, would have cost $160, a ...

Re: getting rid of noise on car radio
Contact the radio manufacturer and let them know about the faulty installation. Try a competitive installer for their opinion.

Good luck! I prefer the older radios over the fancy-dancy new crap anyway!

Re: recovery of gold from electronics
Your biggest problem is how to get to the gold-if it's molded in plastic it's not available for any of your etchants. Exposed gold on connectors, pcb's, etc can be safely etched (disolved into, then reclaimed) by what is called "KI&I". It is a mixture of Potassium Iodide and Iodine. Re...

Re: H bridge mosfet choice?
I used a Curtis Instruments MOSFET controller for a 48V, 175A electric go-kart.

There's many concerns about throttling 5-10 kilowatts that the amateur might do well to leave to a pro! (Heat, emergency shut-down, runaway, acceleration limiting, to name a few) Just my 2c.

Re: 100w bulb in 40w max desk lamp
Keep in mind that bulbs that seem to burn out early, or troublesome lamps, can be a fire hazard.
An electrician would know.
At least keep good batteries in your smoke detectors!

Re: Ways to do things
I agree Perfectbite (retired dentist?)! For common tasks, there's many solutions, but as correct solutions become less and less, the complexity grows rapidly! Then comes the complication of picking the "best" solution. Is best cheapest? Or quickest? Or coolest? When I'm miffed for a soluti...

Re: Ramsey Kits
You'll get some ideas (or copy theirs) on SCA detectors from: http://www.fineware-swl.com/sca.html
Built one years ago for 67 KHz.
Good luck, Mike!
