[edit] 3D printing

• 3D-printer
• Creating a 3D print
• Solidworks

[edit] Modelling

• ShapeLock: rapidly create prototypes

[edit] Sensing

[edit] Sensor interfaces

• CUI: Dan Overholt's open source platform based on the PIC controller. Need the Bootdown to load hex-files.
• Bit whacker: works with the CUI hex files.
• Arduino: open source platform based on Atmel microprosessor. using Wiring for programming.
• Phidgets: commercial USB-based sensor interface with standardized connectors.

[edit] Communication Protocols

OSC:

• OSC: Open Sound Control for communicating between devices.
• uOSC: the Open Sound Control Reference Platform for Embedded Devices, currently working on PIC controllers.
• OSC 2.0: proposed by Jazzmutant at NIME 2006. Extending OSC by adding aliasing, handshaking, querying, etc.
• SLIP: Serial Line Internet Protocol used for creating packets passed over the serial communication.

HID:

• HID: Human interface devices. The game controller specification is the one that is implemented everywhere. The generic HID class would be a better solution for us, but is not supported in Max, SuperCollider, etc.
• USB CDC: communications device class

XML:

• SOAP: XML-based communication protocol. Pros & Cons: extensible & scalable, but verbose.

GDIF:

• GDIF: Gesture Description Interchange Format

MIDI:

[edit] Communication Interfaces

• WiFly: wireless ethernet module

• nRD24H1: 2-way radio controller from Nordic

[edit] Sensors

• Sensorwiki: @ McGill, great resource for information about sensors, interfaces, etc.

Sensors used for finger control:

• Interlink MicroNav 360: XY + pressure sensor
• Interlink FSRs

• Microsoft unmouse pad prototype

Acceleration:

• SparkFun

Position sensing

• Gametrak: 3D "golf" joystick

Cheap 3-pin cables:

• 3-pin

[edit] Actuators

• Internal Combustion Guitar

[edit] Sounding

[edit] Amplifiers

• Charlize: a Tripath Class-T amp based on the Tripath TA2020
• Sonic Impact 5065: Gen 2 T-Amp with Power Supply

[edit] Speakers

• Visaton: speaker elements
• FOXL: small powered speakers. S&R review
• Sonic Impact SoundPads

[edit] Soundcards

• 7.1 USB sound card: $21

[edit] Computing

[edit] Small motherboards/computers

• Intel Desktop Board D945GCLF: with Integrated Atom Processor. Need RAM + CF drive.
• Gumstix: small self-contained computer with audio i/o
• Compulab:
• Beagleboard: $149
• NANO-8044: Intel Silverthorne Atom. 120mm(L) x 120mm (W) x 1.66mm (D). 6xUSB. Gigabit Ethernet.
• Navigator: 5.0" LCD 372MHz CPU Windows CE 5.0 GPS Navigator with 2GB Maps SD Card and FM Radio
• Sheevaplug: fits in the power supply

[edit] Power supplies

[edit] Software

• PDa: Pure Data anywhere. Running on lots of Linux-based systems.
