I started out the same way and now my desk is cluttered with partially completed projects and devices in various states of taken apart. But for me the fun part is learning something new along the project journey. The microcontrollers were a game changer due to their low cost. I’m not trying to fry them, but hey if I screw up who cares it was a couple bucks anyways.

For circuits I design I’ve mostly been having them created overseas and I’ll solder on the components but I’m really curious about hacking a toaster into a refry oven or whatever their called and soldering surface mount components. Not that I need the small form factor or I’m making enough circuits to warrant trying to save on cost, I’m just curious and want to try haha. Gonna need a bigger desk…
