I've been working on this little project for a while and it's near release. It's a tiny underwater vehicle that uses, yep, DC motors! I was introduced to this idea a decade ago at Liverpool Makefest where the Dark Water Foundation had a workshop where people made similar rovs with legos. Mine is 3D printed, designed in FreeCAD and will be featured in an upcoming Raspberry Pi magazine, I'll also release the source for the 3D printed frame and also some little scripts I've used on a Pico controller on a repo after a little tidying. FOr now though, enjoy this little selection of clips from the test sessions in a very 2nd hand inflatable hottub!
