We had Chinese take-out last night, and check out the fortune from my cookie:
It's a sign from the universe about which way to take future projects.

So, the PCB Gremlins got to the TritiLED V3.0 board. The timestamp on the gerber files is at 20:49 local time, making me think that the mysterious PCB-bug-inducing behavior is not limited to post-midnight design sessions.
I ordered the boards before prototyping the circuit: today, on a breadboard, I found the problem - an input line on the 74LVC1G123 pulled high when it should be pulled low. I haven't even received the PCBs back yet. I can rework the three incorrect PCBs easy enough - cut a trace and run a piece of wire-wrap - but it means another order to have a "releasable" version for the coin cell challenge.
Moral of the story: even the relatively early 20:49 is late enough for the PCB Gremlins to strike.

A local store closed about 10 years ago, and the manager sold me this cabinet for $50. No parts inside, though :( It brings back fond memories of projects in my youth.
For years, it was behind my 10m target range, and somehow got hit a few times. This mystifies me, because I *never* miss ... there must be a hole in my trap :-)
