I love soldering and putting together small electronic devices but can never find any kits for anything fun/actually useful. There's always like electronic dice or decision makers but I'd like to find something much more involved. Anybody seen any kits or anything for protects that look both fun and not just super simple like 555 timer circuits and the like? Also if I had to say my skill level it would be between beginner and novice, I can solder circuits all day long with no problems and I love following a set of instructions as long as the end result is something fun.
