A BCD Clock For Your Desk

We see so many clocks here at Hackaday, and among those we see our fair share of binary clocks. But to see one that at first sight looks as though it might be a commercial product when it is in fact a one-off project is something special. That’s just what [Tobi4sDE] has done though, with his desktop BCD binary LED clock.

The front panel is a black PCB on which sit the LEDs that form the binary display, and its back holds an ATMega328P microcontroller and DS3231 real-time clock. A smart desktop case is 3D-printed, and while the clock is …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
