Harbor Freight was giving out free DVMs at one point, so I got a bunch and use them as embedded current/voltage monitors. I mounted the supply on a board with decent bus connections and a current monitor tap. The biggest transducer I can find on eBay is 120 watts, so the range is good. With 12 volts at 15 amps, the system can supply 180 watts of drive power to the transducer circuit. ATX supply makes a good DC supply I'm using a discarded ATX supply as the DC supply for the ultrasonic driver board. Summary 1) The new driver board works 2) An ATX supply makes a good DC supply for the driver 3) An ATX SMPS transformer can drive an ultrasonic transducer 4) I've ordered parts from DigiKey 5) My ears hurt, and I don't know why. (Which looks vaguely like to the starship enterprise.). I've resolved the safety issue using a lasercut holder for the transducer with rubber feet so it doesn't skitter across the table when energized, and a sculpted-foam parasol to catch the ultrasonic energy. I'm looking into generating Hydrogen on a small scale, and collecting plumbing for the experimental setup. My DigiKey order came in, I'm working up the various device interface software, nothing exceptional. Summary 1) Power supply design is coming along 2) Final design will require an embedded Arduino Nano 3) Final design will use a laptop (or desktop) as display Random Status A lot of little things are happening with the project but nothing of special note, so I won't post this to the feed.
