Sensors Workshop 2008 Kit

Posted by Adrian Freed on July 31, 2008

This kit for the 2008 class included materials for scratch assembly of sensors, a CUI board running uOSC and a few tools such as scissors.

How to choose a Tilt/Acceleration Sensor

Posted by Adrian Freed on March 12, 2009

The majority of acceleration/tilt sensors used these days are single integrated circuits MEMS devices. The cheap ones are made for air bag and other high volume applications. Although the chips are cheap ($5-10 Retail,<$1 in quantity), they are usually sold in surface mount packages that are inconvenient to work with without industrial quality tools.

Fabric Proximity Sensing

Posted by Adrian Freed on November 7, 2008

Most sensing applications of e-textiles use switching, piezoresistivity or optics for direct touch sensing. This instructable shows you how to start exploring another approach - capacitive sensing to measure touch and proximity. It is based on the easy-to-use, cheap capacitance sensing chip evaluation board from Atmel/Qtouch and takes only minutes to create.

RGB Pressure Sensitive Monome

Posted by Jeff Lubow on September 5, 2008

Because of the inherent limitations of visual feedback in a single color LED matrix (Monome), I’m starting work with
Adrian on developing an RGB Monome with pressure sensitivity. For now, I’ll focus on the multiplexing/de-multiplexing
process.

We chose the SparkFun button breakout available here:

Big Guitar Controller

Posted by Adrian Freed on May 14, 2009

Dismantle 3 Gametraks and remove the pair of joysticks in each.
Ream out the paddle hole to match the diameter of conductive chord you selected for the strings. I used standard chandelier wire which required a slight enlargement of the hole.
Install the joysticks on the bridge, according to the height and string spacing you have chosen.
Drill the holes in the bridge to pass the chord through.

Fabric Digital Multimeter

Posted by Yotam Mann on July 10, 2008

This digital multimeter is useful for evaluating textiles and thread for conductivity and electrical resistance.
Because each colored led have a different forward voltage different "scales are provided", Blue is good for low resistance,
Green for middle, and red for higher resistance.
