Goggles

The new goggles are done!



Yes, okay, I made a steampunk artifact with non-functional gears. Dammit. But only because I had the brass gears sitting around unused after their failure in the electro-mechanical sunglasses. Once I work out a design/manufacturing approach that prevents them from binding, even with the floating central lens gear, I'm going to redo it all over again. This was really just a testbed for some of the design features for that future version.

These are way more comfortable than the sunglasses are, even with all the extra weight from the brass gears. I would design the leather gaskets (or whatever you want to call the toroids that cushion it against your face) a bit differently if I did it again, and I'd make sure to have enough brown thread on hand. The section of black look really bad. The lenses are just single layers of the polarizing film -- it looked silly not to have something in there, and they're transmissive enough to be worn at night.

All in all, a very successful thesis-avoiding sideproject. I should have some good pictures of me wearing them by the weekend.

or use spiral bevel gears, so the pinions would hold the lens gear in place! the idler shaft could go across the nose bridge. probably harder to fabricate with all the shafts going at right angles though.
