Soldering and like just enough experience with an Arduino, electronics, and Ohm's law to not hurt myself. I replaced USB ports of some DJ equipment that became unusable after a USB cable got yanked. I clip off annoying USB lights. Instead of throwing away my MX Master mouse I gave it another life as a backup. This involved me trying to replace the battery but completely man handling the delicate tiny port, and still make it work. Once I got comfortable opening up the guts of electronics I also got comfortable with general repairs. I replaced my switch joycons that got the drift. Replaced my cracked phone screen. Replaced the rotating clutch in my microwave. So much more.
