myWall

myWall turns any wall into a slow, hand-drawn display. Developed at FabLab Torino for Carlo Ratti Associati and Cassina, it took an earlier, sprawling vertical plotter and packed everything (motors, electronics, power, drawing head) into a 15-centimeter disk.

I designed custom Arduino boards and a Processing framework to generate the vector content, and built the enclosure from laser-cut acrylic and 3D-printed parts, tuned so the pen glides across the wall without jerking.

Scaling up to a large showroom wall magnified every tiny error: the gondola drifted and lines skewed. I recalibrated overnight, measuring cable lengths millimeter by millimeter and adjusting the firmware, and reworked the fonts, kerning, and stroke weight until the output looked like handwriting rather than robot text.

It ran throughout Milan Design Week in Cassina's Fuorisalone space, drawing the collection's colophon.
