Here some photos of the new Vshield. We want to use the jacket for a dance performance and trigger sound effects / videos with it.
We stick to the clever design of the Vshield v.1.0 that was developed earlier with Tyler. For this version we adjusted the sensors to: 

- 3 piezo sensors
- 2 bend sensors
- 1 softpot

Here you see a sketch with the placement of the sensors:

Here a breadboard screenshot of the setup:

A photo of the material: 

Pins
- 1x 3 Break away male pins
- 2x 5 Break away male pins
- 2x 5 Break away female header pins
- 1x 3 Break away female header pins
- 1x 2 Break away female header pins

Resistors:
- 3x 1M Ohm
- 2x 470 Ohm
- 1x 100 Ohm
Capacitors (not in the picture)
- 3x 1nF

PCB board:
- 1x Stripboard (12x 20 holes)

First we soldered the header pins on the side. We just soldered the outer pins and then put the vshield on the arduino. Therefore the pins could easier adjust to the arduino board and fitted perfectly!

Then we stacked the resistors in place. 

Analog in:
0: Softpot
1: Piezo
2: Piezo
3: Piezo
4: Bend 
5: Bend

This is a sketch of a new version for a jacket. It is designed for a local stepper / crumper who wants to use it for his performances. The jacket will include 4 piezo sensors and 2 bend sensors. Stay tuned!

This is another demovideo we did last week July 5th, 2010.

The VJacket is a wearable controller for live video performance. Built into this old bomber jacket are all kinds of sensors to control visuals on the screen: hit sensors, light sensors, bend sensors and touch sliders. This way, the VJ is freed from the boring, cumbersome interface of mouse and keyboard, and instead can use the very clothes on his body to control the videos and effects with a precise dance converting convulsing limbs into luscious light shows. We are transforming this bomber jacket, a symbol of war and destruction, into a tool of creative expression and a symbol of peace. We are also going to release all the related hardware and software as open source in order to spread this transformation across the globe.

The VJacket uses a standard Arduino microcontroller board to relay the sensor data to the computer. To take it from there, we built the Arduino2OSC bridge: an easily configurable graphical interface that creates customizable OpenSoundControl messages from the sensor data. It also allows you to adjust the analog input data from the Arduino to your exact needs – scaling input and output values, adding cutoff thresholds, etc. – with enough options to (hopefully) cover all your Arduino input requirements: no matter if your sensor is a continuous slider or a one-hit piezo contact mic, no matter if you are manipulating a video effect or triggering audio samples, we tried to make it flexible enough so you’re not stuck reprogramming a new patch for every project – just make a new preset and you’re done!

For the above video demo, we used the VJacket through Arudino2OSC to send OpenSoundControl messages to Resolume Avenue, a popular VJ program. The Arduino2OSC bridge interface is generic enough to send any type of OSC message to any program that accepts them, including other video or audio programs like Arkaos Grand VJ, Max/MSP/Jitter, Kyma, etc. You can even send the messages over the LAN for networked performances!

We will soon make available the circuit designs, Arduino code, and Arduino2OSC Max/MSP patch/application – all under an open source license – so stay tuned to make your own VJacket!
