Hobby electronics from 1982
[Lennart] came across one of his projects from several decades ago. It’s a twinkling star which blinks LEDs at different rates using some 7400 logic chips and RC timers.

As part of a class at University, [Emacheen22] and his teammates turned an old Connect 4 game into a binary clock. This image shows the device nearing completion, but the final build includes the game tokens which diffuse the LED light. We enjoy the concept, but think there are a few ways to improve on it for the next … Read the rest
Hackaday’s very own [Mike Szczys] just shared an awesome binary clock he’s been working on. Unlike a normal binary clock that is only readable by self-admitted geeks and nerds, [Mike]‘s clock is nearly comprehensible by the general population.
There are 12 lines of three LEDs around the face of [Mike]‘s clock. These LEDs represent the time in minutes in binary … Read the rest
[linux-dude] always wanted to have a binary clock, but he didn’t want to pay someone else to make it for him. Additionally, he was looking for a compact alarm clock he could take on the road, rather than relying on the one in his hotel room.
Inspired by other binary clock projects he has seen over the years, he … Read the rest
The weekend is almost here and if you’re looking for an afternoon project consider building your own binary wall clock. [Emihackr97] built the one you see above using parts on hand, but even if you put in an order for everything, it won’t cost you much.
He used a cardboard box as the housing for the clock, marking a … Read the rest
Here’s a three digit binary clock that [Viktor] designed. It uses a multiplexed display to drive one digit at a time with a PIC 16F628A. The video after the break shows it ticking away, display hours, minutes, and seconds in blue LEDs. You may be wondering why those LEDs are not flush to the board? [Viktor] took the project one … Read the rest
