While the yellow submarine pictured above doesn’t get marks for pretty looks, put it in the water and the miniature submarine makes up with performance. It’s a powerful remote control beast which also boasts an onboard camera. While it’s not early as impressive as the Star Trek U.S.S Enterprise Submarine we featured, it’s still a superb DIY build.
The PVC sub is a functional ROV with an on-board video camera. It has also been built as a platform for future add-ons such as leak detection, temperature and pressure sensors, torpedoes, grabbing arms etc. The underwater vehicle is made up of PVC pipes and propulsion is with the help of 6 pumps.
The entire sub is controlled by an Atmel Mega32 microcontroller. The video feeds and system info are fed to the surface using a cable (wireless video is a future feature). As you can imagine, the PVC makes the submarine naturally buoyant, but the platform is fully capable of underwater diving. Bonus: detailed schematics are available for reference.
