Here follows my workflow to produce the publication list and bibliography on adrianfreed.com.

Where there is a Whug there is a Way: Triaxial e-textile Breadboard

Sun, 07/16/2017 - 01:16 — AdrianFreed

Description:

Rectangular grids are dominant forms in electronics and textiles. Triaxial grids have not been explored in e-textile work so this breadboard is offered to begin these explorations. Triaxial grids sample the plane with higher density and the availability of whug connections as well as warp and woof simplifies circuits by providing a natural power/ground/signal triple.

Conductive Paper Pressure Sensor and Arduino Teensy

Fri, 08/19/2011 - 20:27 — AdrianFreed

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.

Arduino Music and Sound Weekend Workshop in Berkeley

Fri, 07/02/2010 - 13:16 — AdrianFreed

Dates: July 24 + July 25, 2010 from 10am to 5pm FULL

Description   

During this hands-on workshop we will survey Arduino platforms, libraries, shields and programming techniques for a broad range of musical and sound applications. We will learn how to synthesize useful wave shapes including square, sine, triangle and pulses, how to manage polyphony and timing and how to playback and record sampled sounds.

Wearable Video Game Platform Bracelet

Mon, 06/21/2010 - 13:45 — AdrianFreed
This bracelet has an Arduino-powered ring of white LED's with a 3-axis accelerometer tilt sensor.

How many interactions/games can you think of with this platform?

There are 3 in the video:

Hand in the air: flashes (because at a party you want to signal that you want someone to talk to?).

Horizontal hand: always illuminates the top LED's whatever rotation your arm has ("smart flashlight")

Spins of the wrist: a blob spins around in the same direction and slows to a stop.

For a commercially produced inertial-sensing band keep an eye out on getymyo
