The projects featured on these pages frequently rule the air, the ground, the rails, and even the waves, but very rarely do they rule the deep. Building a submarine is hard, and thus it’s a challenge not taken on by all but the most courageous of builders. This hasn’t discouraged [Timo] though, who has embarked on the construction of what is shaping up to be a very nice underwater ROV build.
The design is straightforward enough, with a PVC tubing frame carrying thrusters for maneuvering, and a central tubular compartment for the electronics and a camera. Control and power comes via a wired connection, and there is a companion controller holding a Pi Pico interfaced to a PlayStation controller.
So far the craft is a work in progress, and he’s engaged in a battle with water pressure to keep in dry inside. The fittings are all 3D printed, and this means a constant battle with warped prints and collapsing infill. He’s not given up though, and is instead recovering enthusiasm by working on the shore-side controller.
We look forward to seeing this project completed, meanwhile if you’re thirsty for more underwater projects take a look at the glider which won the 2017 Hackaday Prize.
