In the end, the secret to keeping my work boots fresh was a tiny pinch of fine powder boric acid, which kills all fungal stuff stone dead. (including athletes foot). The construction of this and it's circuit design seems fairly sensible though. There's no microcontroller, so everything is done with discrete circuitry to add "features". The high voltage section has had the number scrubbed off its chip and black resin painted on some component identifiers, so it seemed a good idea to reverse engineer it as an act of defiance. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. #ElectronicsCreators Wed, 15 Apr 2026 11:15:16 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/843c485d-44a8-4969-900a-041213c217ba All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
