Make your own yellow submarine (of sorts)!
This remotely-operated vehicle, or ROV, is completely DIY. It consists of a frame that holds three motors that allow to move forward, backward, turn to port or starboard, and dive or surface. All movements are controllable through the circuit board that's attached via an umbilical cable.
