Synthesizer Hack – How to Make Pressure Sensor Synthesizer!


For those of you into sound synthesizers, you might want to take a look at this video where the creator uses aluminum foil and conductive foam to make pressure sensing sound synthesizer to make some cool sound effects. (on YouTube)

A first test of a simple DIY pressure sensor surface for controlling analog synthesis. It is built from cheap conductive foam, with aluminium foil taped on both sides in various patches. Only the right side of the sensor surface is connected. The top foil goes to +5V, and four patches underneath are connected to various inputs on the small analog modular synthesizer Chimera BC16 (the white round thing with knobs in the background). In this first test, the following modulation inputs are connected: volume, oscillator pitch and diff (osc 1-2), and filter cutoff.

The aluminium foil is attached to a sheet of plastic, to allow change of layout, and to make the foam piece exchangeable in case it gets worn out. I plan to upload a video showing more details about how it was made.

Materials used: an old cardboard box, a cut-up plastic folder, adhesive aluminium foil, a piece of conductive foam of the kind you use to transport ICs. Total cost: €4.
