Old technology can be simply amazing. Centuries before Arduinos, servos, and electric motors, Japanese artisans came up with the mechanisms for the Karakuri Somersault Doll. The inner workings of the doll were reconstructed from original figurines by the kit builders at Gakken, so you can recreate one yourself! The kit includes everything you need to build the doll including the screwdriver. Once assembled you can adjust strings to control how fast the doll flips down the included platform. Interested?
