HARDWARE COMPONENTS | Spiel is built entirely with open-source software and tools
1- A custom built wearable mouth apparatus, hammered by hand from steel and bronze,
with piezoelectric speaker.
2- Body-mounted Raspberry Pi computer running Linux.
3- 6600 mAh battery providing 2-3 hours of performance per charge.
4- Hidden thumb controlled force sensitive resistor. Attached to the
performer’s hand and invisible to the audience, this FSR connects to
an Arduino micro-controller ,which sends Open Sound Control data to
modulate amplitude of mouth-speaker, as well as to handle
conversation recording (on/off).
5- Integrated IMU accelerometer, gyro, and magnetometer, embedded
underneath the performer’s chin. Wired to an Arduino, this device
provides Open Sound Control data for parameters of Pure Data
6- An embedded cardioid electret in-ear microphone.
1- Homebrew conversation processing tools built in the open-source
Pure Data. Features more than 20 unique digital signal processing
effects controlled via Open Sound Control by the various body-mounted sensors.
2- The free software JACK Audio Connection Toolkit is used to route
audio signals between multiple instances of Pure Data, in order to
maximize multi-core processor efficiency.
3- A variety of custom Arduino software used to receive sensor data. Leverages
the CNMAT/OSC library for receiving data as Open Sound Control
messages across a serial connection.
