Conductive Paper Pressure Sensor and Arduino Teensy

Overhand knot in a strip of carbon-loaded paper becomes an FSR that can be easily connected to your favorite microcontroller (in this case a teensy running with the Arduino C++ tool chain).

This is part of my Fingerphone instrument.

e-textile Interactive Demonstration at Maker Faire 2007

My table at Maker Faire 2007 including my first e-textile work with peizoresistive fabric, and my duotouch pad and floor sensors.

In 2016 I made the video below of a tear-down of those e-textiles with Hannah Perner Wilson.

Our Maker Faire table also include some great interactive demos whipped together by Andy Schmeder.

Audio Sine and Square Wave Signal Generator using a Wavetable

Not my first publication, but my first one with some challenging engineering. I did this in my late teens and it was published in a hobby electronics magazine, "Electronics Australia". I discovered by accident that some folk from Greece published the same ideas in a professional technical journal in 1989 (attached). If you are a scholar of such things it is interesting to compare and contrast the modes of articulation in my vernacular engineering approach with those of the academic paper.
