1980s plotting device turned into a handheld whiteboard tool

Writing on a whiteboard isn’t an easy task for many people, including instructor ‘Kenyer,’ whose lettering can be on display for a semester or more. Rather than accept his imperfect penmanship, he modified a 1980s-era Rotring NC-Scriber—originally meant for mechanical drawing use—to do this for him.

His project runs on an Arduino Uno and motor shield, along with custom mount for erasable markers. Phrases are programmed via the setup section of the sketch, but he hopes to implement the device’s keyboard for control with the help of a different motor driver in the future.

You can see it plotting away in the video below, while code and additional info can be found in Kenyer’s write-up.
