Turn Old Pinball Parts Into A Unique Digital Clock

It’s getting ever harder to build a truly unique digital clock. From electronic displays to the flip-dots and flip-cards, everything seems to have been done to death. But this pinball scoring reel clock manages to keep the unique clock ball in play, as it were.

It’s not entirely clear whom to credit with this build, but the article was written by [Lucky]. Nor do they mention which pinball machine gave up its electromechanical scoring display for the build. Our guess would be a machine from the ’60s, before the era of score inflation that required more than the four digits …read more

Driftwood Binary Clock Is No Hollow Achievement

It’s about time we had another awesome clock post around here. [Mattaw] has liked binary clocks since he was 0 and decided to make one in stunning fashion by using driftwood, nature’s drillable, fillable enclosure.

That beautiful wiring job on the RGB LEDs was done in 18g copper. To keep the LEDs aligned during soldering, he drilled a a grid of holes just deep enough to hold ’em face down. There’s an IR remote to set the time, the color, and choice of alarm file, which is currently set to modem_sound.mp3.

Under the wood, there are a pair of Arduino …read more
