Simple Binary Watch Uses A PCB Body

There are numerous approaches to tell the time, from utilizing analog dials to 7-phase shows. Hackers tend to delight in binary watches, if only for their affiliation with the digital machines that feel to make the environment transform these days. [Vishal Soni] made a decision to construct one of their personal.

It’s a easy style, that utilizes six bits to demonstrate the time. A red light is illuminated at the leading of the observe to reveal the look at is demonstrating minutes, and these are displayed in binary on the six blue LEDs underneath. Then, the enjoy suggests it is demonstrating hrs, and once again makes use of the six blue LEDs to show the appropriate selection.

[Vishal] refers to this as a binary coded decimal (BCD) enjoy, but BCD entails utilizing binary to directly refer to figures from -9. As an alternative, it seems to be a normal binary view applying 6-little bit notation.

The coronary heart of the enjoy is an ATtiny85, It also characteristics a TP4056 for charging and protecting the lithium battery applied to energy the observe. Charging is by using a USB-C port. It’s all constructed on a customized PCB which is created to act as the enjoy physique, with the straps directly connected to the PCB itself. The only detail that appears missing is a 32.768 KHz crystal or real-time clock for correct timekeeping.

All round, it is a fun build that would have taught [Vishal] a lot of handy design skills. We envision people will provide [Vishal] perfectly in upcoming jobs. If you are digging the binary view, take into consideration some of the other excellent builds we’ve viewed above the several years. Video after the split.
