Plotclock Robotic Clock Writes the Time with a Marker

What’s better than a regular clock? Maybe a robotic one that uses a marker to write the time. The Plotclock has an arm to handle a marker and write the time on a mini whiteboard. It also erases the time when it needs to write a new one.

The robot is controlled by an Arduino UNO controller. You can easily build it with a 3D printer.
