I had nothing to do on a Friday night, so i thought I'd try building something useful... After digging through my workshop and using up a good 30 minutes, i had made some safety goggles with a lens on them, so i can look at details too small to see without magnification. I'm not going to include instructions or a super-detailed list of parts, it's just an idea that I'd though I'd share. I started with the lens; i don't know where i got it, maybe from an old, broken telescope eyepiece. I found a hose clamp and tied that around the lens, then put a screw with an L-bracket on it through the part of the clasp still sticking out, and adjusted the clasp and bent it until the screw stayed in place, securing it with a nut. Next, i took a tiny hinge i had laying around, and drilled a hole through the middle of it so i could put a screw through that, again securing it with a nut. Finally, i used some hot glue to attach the other side of the hinge to the goggles. And poof! A magnification lens on some safety goggles. It moves up and down, so you don't always have to look through it.
also, it's my first instructable, so suggestions/comments would be appreciated :]
