I drew my profile pic and banner. The gameplay in the banner is from dragon quest 1 for game boy that I recorded myself.

Electronics are a hobby of mine, interrupted by 2023 being the absolute worst year of my adult life.

I want to build stuff and share the schematics, PCB files etc with the wider world. Many people do that.

Here's my gimmick: I start by building the tools themselves, explaining how they work without expecting the audience to have any pre-existing knowledge. This will be a mixture of Cohost posts and youtube videos.

The projects themselves wouldn't be "i put a raspberry pi in something", but real component level circuit design. For example, the first project in the series would be a laboratory workbench power supply.

There'd also be some digression into autopsies and reverse engineering of dead consumer devices I find, like the trinitron monitor I've got dumped next to my desk right now.

Would anyone here like to see that?

Might be neat to do things like "here's how you safely reuse things" when it comes to things like a lab power supply; ATX 12V supplies are everywhere and conveniently hit the major logic levels, but can be dangerous!

I considered this, but I decided against such a DIY power supply because so many interesting projects need an equal negative voltage, or more than 12V, or both

I'm going to go over the AC power stuff as a matter of principle

hell yes if i'm feeling enterprising this year i'll actually try to build the bench power supply!!!! i don't know anything about anything* but i'm great at learning

*: i do possess some soldering skill but ironically i don't know very much about how electricity actually works so this actually seems like a great project for me
