Periscope, first draft CAD drawings
I worked up some CAD drawings of the periscope. This is a first pass at the design. I have some more work to do but I plan to cut it on the laser cutter in the next few days and try it out. Below are two photos showing the periscope in the "down" position and in the "up" or raised position. There are two handles on the side for pivoting the scope, and a round crank wheel that runs it up on a rack and pinion gear system inside.
