This isn't tech related at all, but restoring old garden tractors. They're generally simple, but there are tons of details between the various manufacturers and models. They're mostly built to be very repairable and durable. Very satisfying to repair something that's 50 years old and have it be just as capable, if not more so, as the cheap ones they sell today.

There's certainly a lot of grace, especially in today's consumption mindset, in repairing a physical device. I hope you can monetize it someday (or maybe not if it will take the fun out of it)
