Cool project! Do you have any kind of black chanmer between the LED and optics? Like inside cameras between the inner lenses and the image sensor/film? That would probably give a lot better image, since the light would not bounce inside the box weakening contrast and sharpness. I wish I had time to build this projector, it would be super fun and interesting :)
Very nice! Especially the part of the vid showing the rework of the transformer's secondary - super simple! Maybe I'll make something similar from alu extrusions without a welding machine...
Sweet!Looks like it might benefit from a bit more ballast (or how is it called). A keel I mean, weight in the belly to take it bit deeper and stop it from turning side to side when wagging the tail... Also a more flexible tail might make it swim more efficiently.
