That's so sweet project! Read this in the morning and have been designing my own version of epoxy frame CNC all day :D Super inspiring!Do the ball screws really need a system to lube them instead of the user manually adding some oil every now and then?
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.
