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 at 1010.co.uk> if you plan to
attend, and indicate whether you will need a sensor input board for

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.

sensors for musical use)

---What to bring:


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
3) Soundcard (internal or external, quality a non-issue)
4) Headphones
5) EUR 10 participation fee (+ 8 euros if you need a sensor board)


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

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



A (more-or-less) weekly series of constructivist workshops
emphasising making and connection within the field of the existent.

Forthcoming matter:

May 3rd: Ephemeral Exposures//Instant Imagery with Alice Miceli And
Kathrin Guenter

Kirlian photography, radio telescopy, data forensics, EVP/ITC, scrying
boards, KiCad PCB design, CMOS audio synthesis, GStreamer framework

... contact if you're interested in leading a related workshop.



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 at scrying.org), Julian
Oliver (http://selectparks.net/), Derek Holzer
