April 26th 2PM: AVR/HID Sensor Input into Pure Data with Derek Holzer & Martin Howse

We will continue last month's investigation of quick and cheap ways of getting sensor input into the Pure Data programming environment, using either USB game controllers or ATmega8 microcontrollers and the HID (Human Interface Device) protocol. Participants should bring the AVR/HID boards and/or hacked joysticks from the previous workshop. Those who did not attend the previous workshop are welcome, and ready made sensor boards can be purchased as part of the participation fee. Please RSVP to m@1010.co.uk if you plan to attend, and indicate whether you will need a sensor input board for Saturday.

A few (!) sample sensors will be provided, but participants are encouraged to bring their own sensors (light, pressure, motion, etc...) for experimentation. The Pure Data programming environment will be used to get the sensor information into the computer and map it to different parameters, ranging from MIDI to direct control of audio or video.

Windows users should be aware that the possibilities for input on their systems may be more restricted. GNU/Linux and Mac OS X users should not expect any problems.

Some links for those interested:

http://1010.co.uk/avrhid.html (AVR/HID board documentation) http://puredata.info/downloads (install PD-Extended 0.39 from here!) http://www.sensorwiki.org/index.php/Main_Page (comprehensive list of sensors for musical use)

---What to bring:

Essential:

1. Laptop running Linux, OS X or Windows (be advised that Windows

users may have fewer possibilities) 2) Pure Data Extended 0.39 installed from: http://puredata.info/downloads (please mind that it is Extended and 0.39!!!!) 3) Soundcard (internal or external, quality a non-issue) 4) Headphones 5) EUR 10 participation fee (+ 8 euros if you need a sensor board)

Recommended/Suggested:

1. Sensors of any kind
2. USB game controller of any kind
3. Microphones or other sound inputs
4. Your own project ideas for discussion

---About the Teachers

Derek Holzer [USA 1972] began working with Pure Data in 2001. Since then, he has taught and performed with the program across Europe, North America, Brazil and New Zealand. His work focuses on field recording, networked collaboration strategies, experiments in improvisational sound and the use of free software such as Pure-Data. He is currently writing a beginner's manual for Pure Data. http://www.umatic.nl/info_derek.html http://www.umatic.nl/workshops.html http://flossmanuals.net/puredata

Martin Howse operates within the fields of discourse, speculative hardware (environmental data in open physical systems), code (an examination of layers of abstraction), free software and the situational (performances and interventions). http://1010.co.uk

Background:

Workshops led by field-expert practitioners extend over realms of code and embedded code, environmental code, noise, transmission and reception, and electromysticism. Workshops solely utilise free software and GNU toolbase.

Practitioners have included Martin Kuentz (prd@scrying.org), Julian Oliver (http://selectparks.net/), Derek Holzer (http://soundtransit.nl), Jeff Mann (http://jeffmann.com), Martin Howse (http://1010.co.uk), Fredrik Olofsson (http://www.fredrikolofsson.com/), Florian Cramer (http://cramer.plaintext.cc:70/), Brendan Howell, , jo FRGMNT grys(http://tob.de.vu/), mikomikona http://www.zuviel.tv/mikomikona.html
