Magna doodle clock draws the time

By Ben Everard. Posted

If you’re sick of getting information from glowing screens, this project is for you. This brilliant clock draws the time on a Magna Doodle, then wipes the digits that have changed, and draws the time again, over and over. It’s powered by an Arduino Nano, three stepper motors, and various other electronics – we want one for the office. Every hour it’ll change to a random font stored on an SD card – the maker advises using fonts that don’t overlap, as the machine needs to be able to wipe off the digits when the time updates.
