Hey, ever since the dawn of time, I have wanted to make jewellery that you could wind up and then the little motor would make this little creation come to life. Until now that idea was stowed neatly away in the too hard basket. The other day, however, I noticed it in the too hard basket and decided to see what could be done. I had a couple of super cheap dancing robots that had broken within the first couple of dances, so I dismembered them and pulled out their drive mechanism. Made of cheap plastic gears and a spring.
Anyways, I was able to take these parts and cast them in bronze, as seen here.
With much tinkering, filing, and polishing, I was able to get the mechanism to work. Not perfectly but pretty good. It still sometime stops before it completely unwinds. Anyways definitely a proof of concept that has got me imagining all kinds of wondrous uses for this new technology.
Here's a little video of it working.
