RE: [TCML] OT high voltage DC power supply PLEASE HELP
Hello Andrew,
Would using a flyback transformer from a computer monitor not work? The driver circuit can be extremely simplistic, involving as little as wire, resistors, a transformer and a single transistor.. Alternatively (and much more reliably), one can use the most common IC in the world (the '555' chip), build a tiny oscillator and drive a transistor with it. It isn't difficult to do, and the results are more-than-sufficient for lifters. The DC output can even have as few milliamps as five, quite easily. The Watts(in)=~Watts(out) rule still applies. ;)
Best of luck,
- Christopher Karr
P.S. If the PSU is sorely needed and there is insufficient time to build it, I could build one and send it for free, or the price of shipping, should you desire.

> Hey everyone, hoping some of the veterans here could help. I'm supposedto be helping this summer at a community college with an engineeringcamp targeted towards middle and high school students. They were in needof some ideas for the camp, not to mention ideas to replace the currentideas. The person running the camps idea of an engineering camp isletting the kids build things out of popsicle sticks... Shes going tobore them to death! If they wanted to do that, they could go to a girlscout craft camp... When they come to a college, they expect to bewowed. Point is, these camps are intended to get kids excited aboutengineering, math, and science. To replace some of the popsicle stickstuff we thought of the perfect solution. Have the kids get into teamsand have them each build an ionic lifter. Heres where someone here canhelp. Community college budgets are small enough as it is, and finding a20,000vdc or higher power supply is becoming very difficult. Does anyonehave an old one lying around in the garage. I know all of us have alittle bit of everything stashed everywhere. If someone is not using itand would be willing to donate it to the college, we would reallyappreciate it. Just need something capable of creating the effect forthe students. Thanks ahead of time guys!
