Well, my biggest project most definitely was a machine that caused the whole world to be polluted. I know, that doesn't sound great, but I was under some brainwashing. It was still my own skill.

[Otherwise though, his more sane projects.]

I've also made radio video phones pretty much from scratch and also a small robot army that explode that I can control on a joystick. I've also opened up a robot to find out why it stopped functioning... sort of an autopsy.
