This 3D Printed Clock Writes the Time with a Marker
Plotclock is a clock that uses a marker to write the time on a small whiteboard. When the time changes, the clock erases the previous time and writes the current one.
To make your own plotclock you will need:
– Laser cutter or 3D printer
– 1 Arduino uno single-board microcontroller
– 3 servos
– 1 dry wipe pen
– M3 nuts, bolts, thread tap
You can download all the instructions and 3D print files required to make your own plotclock here.
People around the world have already attempted to make their own version. You can find a small gallery here. Since plotclock is open-source, others have already begun ‘remixing’ and modifying the design. You can find a small gallery of ‘remixes’ here.
