<nettime-ann> xxxxx workshop_21_22 Berlin: High frequency sniffing and Cinelerra |
. A (more-or-less) weekly series of constructivist workshops emphasising making and connection within the field of the existent. Upcoming: 11th August 2PM: High frequency (0.1-2.5 GHz) sniffing and spectral analysis with ap/xxxxx. Details below 18th August 2PM: Free software video editing with Cinelerra and Florian Cramer. Details below Summer highlights: Collective radio telescope construction, GNU Emacs (again) and... noise_produce summer edition. 5/6/7/8 September (see below) ... or contact if you're interested in leading a related workshop. //<------------------------------------------------- 11th August 2PM: High frequency (0.1-2.5 GHz) sniffing and spectral analysis with ap/xxxxx. A practical examination of wide band, high frequency RF/EM emissions in a small part of Berlin. Participants will construct a sensitive high frequency sniffing device based around the tiny Analog Devices's AD8313 logarithmic detector chip which provides an audio signal output for recording, ambient use (en route) or spectrum analysis. Participants will construct a simple, surface mount component-based board which can then be used as a portable sniffer. We will also examine further amplification and antenna designs: the famous cantenna perhaps, or humble dipole. Finally, Baudline software will be used to analyse local signal spectrum. Requirements: All tools provided, a Baudline equipped laptop would be helpful References: http://www.baudline.com/ http://f6bon.albert.free.fr/Milliwattmetre.html http://www.analog.com/en/prod/0%2c%2c770_847_AD8313%2c00.html http://www.turnpoint.net/wireless/cantennahowto.html http://www.engadget.com/2005/11/15/how-to-build-a-wifi-biquad-dish-antenna/ Course fee: 18 euros including all parts Please RSVP [email protected] to reserve places as soon as possible //<------------------------------------------------- 18th August 2PM: Free software video editing with Cinelerra and Florian Cramer Cinelerra, free/open source video editing heavyweight: Cinelerra is _the_ program for semi-professional and professional video editing and compositing on Linux. Thanks to many years of development and a substantially improved community version http://cvs.cinelerra.org, it has matured into a free alternative to such proprietary heavyweights such as Final Cut, Premiere and Avid Express. It is also interesting as a free (as in speech and beer) upgrade to iMovie-style, artistically limited video editing programs. On top of non-linear, non-destructive, multi-track, resolution-independent editing of SD and HD formats and keyframed parameters and effects, it integrates a compositing engine with virtual "cameras" and "projectors" and can use spare additional computers as a "render farm". Seamlessly integrating multitrack-layering and compositing into its editor, Cinelerra lends itself particularly to artistic/experimental video work. Caveats: Cinelerra is overkill for simple trimming/adjustment of video files or camera recordings. (avidemux, Kino, and kdenlive are more suitable free software solutions for this task and will be briefly covered in the workshop.) It is also a bottomless pit of resource hungriness. Your PC or laptop should have at least 1 GB RAM, a Pentium M/Centrino with at least 1.5 GHz, Athlon 64 or PowerPC G5 with at least 2 GHz, Pentium 4 with at least 3 GHz; Core Duo or Athlon 64 X2 CPUs are preferable. The workshop is open to people who are curious about Cinelerra and just want to listen. Active participants however are expected to be Linux-savvy and have a CPU-optimized version of Cinelerra-CV up and running on their computer. (For Debian, the packages from http://www.kiberpipa.org/~minmax/cinelerra/ are recommended, http://www.kiberpipa.org/~minmax/cinelerra/builds/pentiumm/ for PCs with Intel Centrino and Core Duo; in Gentoo, run "emerge cinelerra-cvs"; for other distributions see http://cvs.cinelerra.org/getting_cinelerra.php.) In order not to get delayed and sidetracked, there will be no installation support in the workshop.

Course fee: 10 euros Please RSVP [email protected] to reserve places as soon as possible //<------------------------------------------------- noise_produce summer edition. 5/6/7/8 September: Four days of advanced construction of noise (any) electronic apparatus using all manner of techniques (including free software PCB schematic design and etching, AVR/ATmega microcontrollers). Audio project work or computer interface appreciated. Full technical support, potential circuits, advice and parts provided. There may be a final performance. Please register with projects now. --- Background: A weekly series of constructivist workshops emphasising making and connection within the field of the existent. 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 include 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/), superfactory (http://superfactory.biz), Florian Cramer (http://cramer.plaintext.cc:70/), Brendan Howell Please RSVP [email protected] to reserve any places or register interest.
