A wall-hanging plotter draws multi-layer circuits on vertical surfaces using two stepper motors, a pen carousel with conductive/dielectric/cleaning inks and an optional laser cutter, and adjusts pen height with a force sensor and linear actuator to handle textured walls. It achieves 0.1 mm XY resolution and 1 mm smallest feature size, demonstrates five apps including an FM energy harvester powering a Bluetooth sensor and a 110 cm interactive lamp assembled from 2D cutouts, and is open-sourced.
