Now our code's generating an almost-1 Hz rhythm; we need a suitable case to house it in.
Taking inspiration from our cardboard prototype earlier, I designed the following papercraft net that can be produced on any home colour printer. Faux-woodgrain is the hallmark of the best cheap-and-nasty electronics!

Real metronomes often have a list of tempos such as Largo, Adagio and Allegro to mark how far out you should move the weight to moderate the ticking. I've included some suitably silly tempos for our display.

Putting the electronics, the code and the papercraft case together gives us our finished metronalmost.

It's funny, but leaving the metronalmost running for any length of time really seems to put your nerves on edge. You can't quite get a handle on when the next tick will occur, and that seems to make you feel especially uneasy. It feels like my heart actually starts to race when I'm in the room with it for more than a few minutes.
