Did anyone figure out details of the "full of awsome" thread.
There are two rotating diffraction gratings, done using lego. The tricky part will be the fact that the rotating cogs holding the gratings are clear in the middle (i.e. an annulus), allowing the laser light thru, so cannot accept an axle in the centre. It was not clear what was holding those cogs in place in the absence of an axle, or where those parts came from eg a certain lego model or part.
I have a box of technical lego from the 1980s and am thinking of giving it a go. Will probably need to get a few new parts.
