It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount of work he put into this one, we’re going to guess it will be something interesting. The stated ...

The theory behind building power supplies is relatively easy, but putting it into practice and building a multi-kilovolt supply is hard. A big transformer in air will simply spark to itself, turning ...

In a previous article, I wrote about generating negative voltages via a standard unipolar dc power supply outfitted with polarity-reversal relays (see “Turn Positive Voltages Negative With Relays”).

PC power supply standards change so slowly, the last major revision to Intel’s ATX power supply guide is likely older than your car, your refrigerator, or your children. But this year, Intel unwrapped ...
