A BCD Clock For Your Desk

Posted on by

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

Posted on by

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

Disco Flashlight Binary Analog Clock?

Posted on by

As multitools have lots of different functions in one case, so [Shadwan’s] clock design incorporates a multitude of features. He started the design as a binary clock using a Fibonacci spiral for the shape. However, the finished clock has four modes. The original binary clock, an analog clock, a flashlight (all lights on), and a disco mode that strobes multiple lights.

[Shadwan] used Rhino to model the case and then produced it using a laser cutter. The brains are — small wonder — an Arduino. A 3D-printed bracket holds everything together. You can see the result in the video below. …read more

Gutting And Rebuilding A Classic Watch

Posted on by

No, that watch isn’t broken. In fact, it’s better.

[Lukas] got so used to his binary-readout ez430 Chronos watch that when the strap disintegrated he had to build his own to replace it. But most DIY wristwatches are so clunky. [Lukas] wanted something refined, something small, and something timeless. So he shoe-horned some modern components, including an MSP430, into a Casio F-91W watch.

The result is a watch that tells time in binary, has a built-in compass, and with some more work will be updatable through an IR receiver that he also managed to fit in there somehow. Now he …read more
