I like wiring. I don't use wi-fi, and have never owned a TV remote control. I'm currently re-arranging all my computer and audio gear, so it gets tedious, but there's one less layer to the onion when chasing problems. I'll also be re-wiring my RV accessories into a new car. I'm using the power connectors from RC models for high capacity and minimum size.
I enjoy house wiring, too. One time, I was given a 220 Volt monitor, and I used the same trick I'd used earlier to use a junk stove element as a hot plate by holding it in the shop vise. I made an extension cord with two plugs and one outlet, using the hot wire from each plug and ignoring the grounds. If you plug it in to two different wall sockets, you get either 220 volts, or a nice, safe zero. Just don't have it plugged in if someone is trying to work on one of the circuits you are using.
That's zero volts between the outputs - you could still get a shock from a ground. There are a surprising number of live, ungrounded things around that are mainly dangerous if they are within reach of plumbing where someone might touch both. I have the ability to sense AC on a surface, even those touch-sensitive lamp switches. Bizarrely, I also get it on a small brass object near a computer power supply.
In old, now-crowded houses it was not unusual to have people complain about one fuse always blowing. (circuit breakers are a big improvement) I'd open up the panel, and see two or three wires on that one fuse. I'd make a map of which fuses ran what, and re-arrange the pairs for a better balance, solving the problem.
