Viridis: a student-built, 3D-printed submarine
Viridis documents an open-source miniature submarine project, with two propulsion variants, technical specifications, and links to its models, firmware, and documentation.
- For
- DIY ROV builders and student engineering teams
- Worth noticing
- Both variants share a roughly 250 mm hull and list a 10 m maximum depth; one uses a flywheel, the other four thrusters.
Field notes
The page explains ballast-based diving and resurfacing, plus forward motion and turning through thrusters, and distinguishes the flywheel and four-thruster variants. Its specifications list an Arduino Nano, a 12 V 0.8 Ah battery, and PETG parts; the project history also describes pressure-chamber checks and a water test at TechTower. A timeline marks publication of some project files as planned, though the page also links to GitHub and documentation.
