The Beavis Audio Heterodyne Space Explorer, based on the CD40106.
It seems to be finished. I put it all together and it worked fine, except for two pots that occasionally shorted against the lid.
See the updated video link for a really long test drive.

I'm one knob short. Fortunately, they haven't shut down all the Radio Shacks in this town yet. I wanted to use the 3/4" fluted hex knobs from RS, but they're too short for the pot shafts. I happened to have a single RS control knob, which is a healthy 18.88mm tall. These will leave just enough room for movement.
The current picture is just a teaser. The board is all done except for connecting up the panel mount components of which there are several. Okay, so the board is half done.
