I’ve worked on it off and on for a few months, but finally decided to finish it this weekend.  On Saturday, I tweaked some dimensions and laser-cut the final enclosure.  I wasn’t happy with the button holes and text I had on the front of the first iteration, so I got rid of them for the final.  You can adjust the time by slipping a jeweler’s screwdriver or a paper clip through a gap in between the plexiglass sides and pressing the buttons to add hours or minutes. 

I added a small single-pole, double-throw toggle to switch between bright and dim, then soldered the connections before closing it up.  The whole thing is clamped together by a single #10-32 machine screw and a wingnut.  The final result doesn’t look half bad.
