Everything I've logged along the way — from small annoyances to products already in testing. The ideas sit out in the open, because I'd rather build them with someone than hide them in a notebook.
A ballasted frame that holds an action camera steady and the right way up when you lower it down the pot line or the mooring.
A tapered TPU restrictor that clamps around the cable where it leaves the plug, so it cannot bend tighter than it is rated for.
A modular arm that puts the torch 25 cm out to the side, so the particles in the water do not light straight back into the camera.
