Voltmeter Clock Has The Time Dialled In
A unique clock has been created using voltmeters to display time. The design features an AVR128DB28 microcontroller that drives three voltmeters for hours, minutes, and seconds. The clock is housed in an aesthetically pleasing wooden case with curved panels.
- ▪The clock utilizes an AVR128DB28 microcontroller running at 8MHz.
- ▪Three Baomain 65C5 voltmeters are used to indicate hours, minutes, and seconds.
- ▪The voltmeters are controlled by pulse width modulation coded by the creator.

Voltmeter Clock Has The Time Dialled In No comments by: Zoe Skyforest May 18, 2026 Title: Copy Short Link: Copy You could make a clock with three hands spinning about nested central shafts. If you did that, we probably wouldn’t publish it on Hackaday unless you really found a way to make it interesting. Make a clock out of voltmeters, however, and that usually catches our eye. [lcamtuf] has done just that. The heart of the build is an AVR128DB28 microcontroller, an 8-bit microcontroller that is still currently in production. It runs at 8MHz, and drives a series of three Baomain 65C5 voltmeters to display hours, minutes, and seconds. Each has a custom printed face with the correct number of 13 or 61 divisions as needed.
