I don't know why I never came in this thread before...I could contribute daily.
Let's see...
Recently been completely rewiring an Austria CNC lathe for new Linux based control and stronger motors:
Spent 2 hours with the cops at work because I did some evidence collection and cross-collated video footage of an...incident...at the shop last week.
At home just rewired the kegerator, the circulating fan blew out, and in the process of replacing it I learned that the 50 year old unit I have, at some point in time, had some internal wire fray and the case was energized. I never knew, because I never touched it when grounded.
Also in the process of trying to rebuild the actuator of our driveway gate, I fixed a major electrical issue (one of the relays must have started arcing and fused, burned some wire and blew a fuse). Had to remove the board, desolder the relays, replace them, and redo some wiring. Now, the controller works great, but the old actuator is slipping because it's now actually getting all of the current that the system is sending to it...
Oh, and telescopes. Reverse engineering a common but poorly designed telescope control package, hoping to make it much better. I also have a customer who wants me to learn and install an advanced go-to system from Japan on a rare Japanese mount, they have no support in the US so I might be the first to do this upgrade on my own.
Recently fixed a 35 year old camera flash cable which had a poor casing (UV degradation), I plasti-dipped the cable by hand several times and it turned out pretty darned good.
Um...changed a co-worker's battery? That actually took 30 minutes because it's a Ford Transit, and you have to disassemble the intake and battery box to slide the battery itself out.
All while getting addicted to No Man's Sky...
