Some months (years, now?) ago, I managed to rip the ground-lead out of the CCFL tube. Whoops!
Turns out the lead into the tube was fine, just the wire broke off the solder-joint... So it was a relatively easy fix. And now it runs again! In the simple binary-clock form shown in the main images.
Though, it's kinda fun to revisit the last log... wonder why I never got around to that... I dig the colorful "abstract art" aspect of it :)
