An interactive booklet called Papier Machine is making beautiful STEM toys that are actually fun and accessible, by combining paper with electronic circuitry. The booklet contains pages silkscreened with conductive silver ink that can be assembled to create six electronic paper toys. It also comes with two button cells, two metallic marbles, two piezo elements, and two sound components that can be reused with each interactive toy.

The first in a collection of thematic books, Papier Machine Vol.0 focuses on the theme of sound. “Circuits hide a surprising narrative potential that we wanted to make visible,” the video below explains. Users can close the circuits by drawing them in with a graphite pencil, and play around with the pitch and volume of the sound.

All six electronic toys — Resistance, Gyroscope, Playing track, Wind sensor, Writing track, and Tilt Switch — come with their own user manuals. Much like an Ikea assembly manual, there are no written instructions, only visual steps, so users aren’t limited by language. Pages are pre-cut, pre-folded, and glue isn’t necessary, as everything fits neatly together. You can erase the graphite lines and redraw them, which means you can play with Papier Machine as many times as you want, as long as you take good care of it. (It is paper, after all, so be gentle!)

“Resistance – Like any music instrument, this piano needs to be tuned. The pitches are determined by hand-drawn graphite zones. Graphite being conductive, these zones complete the circuit. Closing the doors finishes to close…
