Anyone looking for a DIY project to keep them busy over the next few weeks might be interested in this very original and unique looking Voltmeter Clock that has been created by Instructables user Oliverb.
The Voltmeter Clock has been constructed using three analogue volt meters together with a micro controller that is used to display the time by varying the voltage to each voltmeter.
Watch the video below to learn more about its construction and how it practically tells the time. Its creator explains a little more about the construction and inspiration for this awesome voltmeter clock.
This clock tells the time – hours, mins, and seconds using 3 analogue voltmeters. A PIC16F628A microcontroller is used to display the time by varying the voltage to each voltmeter and also provides very basic timekeeping. The Microcontroller code is written in Picbasic Pro 3.
Accurate time is maintained by synchronising the clock to my Master Clock that is synchronised to a radio “atomic” clock. The clock is based on an instructable “Multimeter Clock” by abbtech .
The clock also has a chime board but this is completely separate from the clock and is controlled by my Master Clock so is not covered here. If you want to see details of this board have a look at my Voltmeter Clock page for details. In my latest clock I now use a sound board from Adafruit this is far more configurable and has CD quality sound.
