A household staple during the era of CRT televisions, these devices can still be readily found online or even salvaged from a broken TV. We&#8217;d recommend searching eBay for new old stock (NOS) transformers rather than risk getting blown through a wall while poking around in an old TV you found on the side of the road, but really it all depends on your experience level with this sort of thing.<\/p>\n<p>In any event, once you have the flyback transformer in hand, the rest of the build is very simple. [Jay] demonstrates how you can determine the pinout for your transformer even if you can&#8217;t find a datasheet for it, and then proceeds to assemble the handful of ancillary parts necessary to drive it. Housed on a scrap of perfboard and mounted to a piece of plastic to keep stray objects away from the sparky bits underneath, this little power supply would be a reliable workhorse for anyone looking to start experimenting with high voltage. <a href=\"https:\/\/hackaday.com\/2016\/07\/13\/expanding-horizons-with-the-ion-propelled-lifter\/\">Perhaps an ionic lifter is in your future<\/a>?<\/p>\n<p>Readers with a photographic memory may recall that [Jay] used this same diminutive power supply in <a href=\"https:\/\/hackaday.com\/2020\/08\/05\/pour-yourself-a-glass-of-100000-volts\/\">his recently completed water-based Marx generator<\/a>.<\/p>\n<p><span id=\"more-427716\"><\/span><\/p>\n<p><iframe class='youtube-player lazyload' width='800' height='480' data-src='https:\/\/www.youtube.com\/embed\/qaGmNRZG-Yg?version=3&#038;rel=1&#038;fs=1&#038;autohide=2&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;wmode=transparent' allowfullscreen='true' style='border:0;' src='data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==' data-load-mode='1'><\/iframe><\/p>\n<p>source <a href=\"https:\/\/hackaday.com\/2020\/08\/23\/a-miniature-power-supply-for-high-voltage-hacking\/\">https:\/\/hackaday.com\/2020\/08\/23\/a-miniature-power-supply-for-high-voltage-hacking\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you&#8217;re looking to experiment with plasma, you&#8217;re going to need a high voltage power supply.
