this looks pretty neat. for those of us who wear eyeglasses, how hard would it be to modify the 3d printed portions to work with an existing frame and lenses. i'd love to try out something like this, but i need my glasses to correct for astigmatism.

that's really cool. I'll remember that trick we the sare component leg as an offset for the flush cutters next time I'm soldering anything through hole

i've never understood these alternative energy people who are paranoid about their "idea" being stolen. if they patent, it's all going to be out there anyway, and if they don't they can't sell or license it without it being stolen anyway, so what are they protecting, their lack of profits and licensing deals? not to mention that if they die, it's probably all going to be lost because they didn't document or collaborate out of fear of someone stealing the idea they're not making any money from. sounds like your friend is a paranoid nut, or his machine is a fake, because if i had this idea and wasn't making money off of it, i'd just file patent docs and let any friends who were interested build their own, share the wealth. inventors like to show off, as much as they can, while f...

you could improve precision and reduce chatter by using the first version of the CNC to cut more precise parts to replace the hand made parts and give perfectly square and precisely drilled holes. the linear motion could be improved with cheap ACME rods and bearings off Ali Express to get rid of the backlash and slop inherent to normal threaded rod or belt drive setups. also, rubber gaskets between motor/router mounts and the frame would dampen vibration. just a few ways you could further improve your current machine.

cool concept. any chance of posting the eagle files for your GM tube board design? it's a much cleaner design than i imagine i could pull off and it would really drop the bulk of my project versus using one of those large mightyohm boards. good smd hand soldering practice too i imagine.

all silicon semiconductors are sensitive to radiation, and in this case you have an unshielded diode already intended for sensing, which if you reverse bias the diode and shield it from visible light, you can register the hits from beta and gamma (alpha rarely can penetrate even thin fabric shielding) radiation by amplifying the tiny signal you get and reading the output data with a microcontroller. depending on how you set it all up, you can even get a rough idea of the energy level of the particle that caused the hit.
