One of my favorites is an RC boat made out of metal. It turns out that you can get 0.3mm thick, tin plated steel, cut it with scissors, bend it, and solder it together with a normal soldering iron.

Another other one would be a split keyboard, for which I designed and built everything (case, pcb, plate, software) from scratch.

I used to make RC planes and quads, it was super fun, and there's a huge community of foam board planes which are pretty fun and easy.

which style keeb did you make? :D

I tried to get into RC planes, but not living near any places where flying is even allowed really ruined those plans.

As for the keyboard, it is a split arisu style keyboard: https://fosstodon.org/@TT_392/109920314230277590
