DJ Hoodie is a wearable interface that includes 4 channel zipper switch, fabric buttons with LED indicators and fabric pressure sensors. Two of these hoodies are connected with knitted stretch sensors on the hoods. It interfaces with computer with Firmata library and Pduino.using
It appeared in the performance “Cassette DJ Hoodie Battle” by Mika and Clemens Pichler at STWST, Linz, Austria as a part of LABOR FÜR ELEKTROAKUSTISCHE MUSIK UND NEUE MEDIEN LINZ event.
In this performance, two performers, wearing the DJ hoodies are spontaneously sampling sound from cassette players and applying filters. Each Hoodie controls sample channel and choice of filters on PD patch. The knitted stretch sensor connecting the two hoodies modifies a parameter of the applied filter as performers move their heads.
DJ Hoodie is built on a normal off-the-shelf white cotton hoodie.
The front zipper of the hoodie is modified to a 4 channel zipper switch. It was lucky that the hoodie had a metal zipper, which made a good connection to the .
One of the hoodie consists 4 fabric buttons with LED indicator. I used 10mm pink LED and covered with polymorph to diffuse the light. The legs of the LED are made into little loop so it can be sewn with .
The other hoodie consists 2 neoprene pressure sensors.
All the electrical connections between the sensors are made with sewing machine stitches using Silver Plated Nylon 117/17 2ply conductive thread as top thread on the machine. The connections to cables that connects to Arduino is made with Wire loop/Conductive thread technique.
Since it was not necessary to be “wireless” for this performance, I used two big USB Arduino with cables. The Arduinos and breadboards were hidden in a shoebox to be authentic(!). For pull up resister, 10k ohm resistors were used for all the digital sensors (zipper switch and fabric buttons) and 1m ohm resistor was used for the knitted stretch sensor.
