Photos From The Video Workshop

The video workshop Alex and I gave was one of the best I have delivered, all 15 attendees got to take home a working CHA/V module they built in the class, it's a hacked VGA signal generator that basically allows you to build a simple video synth by adding some home brew or off the shelf oscillators. We had a great mix of attendees and they were all from really interesting backgrounds and super engaged. Alex as usual did a nicely paced video synthesis tutorial and I then lead the theory and building part of the class. We rounded up with Alex leading a discussion around historical video synthesis work and then proceeded to enjoy the evening concerts that were also part of the fantastic Brighton modular meet. (Pics 3+9 here are from Fabrizio D'Amico who runs Video Hack Space) Thanks to Andrew for organising the amazing meet which hosted the workshop, Matt for making our panels last minute, George for helping us out on the day and Steve from Thonk for supplying some components for the kits.

Video Circuits Workshop 01/07/17

Alex and I are running another workshop, this time at Brighton Modular meet book here:

We will also be running a video synthesis room all Sunday.

Come hang out and enjoy the rest of the meet.

Some pics of the panels we had made by Matt for Jona's CH/AV project (which we will be making on the day). There is also a shot of some audio oscillators driving the CH/AV to a VGA monitor.

DIY video VCO

Here are some shots of early XR2206 based video VCO experiments, the important thing with video is getting sync pulses from your SPG in to a format that your oscillator circuit wants to sync to, some are fine with narrow pulses some want a nice clean saw wave or for the pulse to hit a certain voltage threshold. This means if you don't have the skills to attempt at modifying whatever SPG or VCO you have chosen you will need sync conditioning circuits to sit in between getting the two to talk nicely.

Video Glitch Device

Here is a device I built for a fellow artist, there are a few shots of its slowly disrupting a shot of a grid to give you an idea off the effects it can produce.

Analogue Video Workshop

So the Video Workshop went really well, we are planning to do more but I also have a bunch of other related projects going on at the moment, so if you want to host one send me an email and I am sure we could work something out. I currently have a diy sync-gen on the workbench and have been generating a lot of footage, theres nothing like meeting a bunch of people and getting them enthusiastic about video art to scare you into finishing some of your own work. Thanks to all who were involved in putting the workshop on including Encounters, Seeing Sound, Arnolfini and Bath Spa University.

oh yeah and one of the attendees wrote us a very nice review, which I think is a really kind thing I should do more often when I go to talks.

F.C. Judd

The work of Frederick Charles Judd previously neglected somewhat by the history books, has over the last few years received renewed interest due to Ian Helliwell's work. Ian's articles, films and exhibitions have collected and disseminated many of Fred's forgotten work and ideas. One of these was his Chromasonics system, which effectively combined CRT based Lissajous figures with a high speed colour wheel to allow full colour display of the electronic images with movement generated by sound. Fred also wrote a series of articles in Practical Electronics magazine on how to construct such a system as well as other audio visualization techniques such as colour organs. Fred is now recognised as an important electronic and tape music composer with a re-issued collection of works available here.

I wanted to focus on his visual work, so here are a series of scans from my collection and some links.

Here are some stills of the images generated by the 

Chromasonics system 

They are very reminiscent of work by Ben F. Laposky although moving rather than static photographs. Fred was also aware of the Oramics system build by Daphne Oram which also used CRT's. Orams system however used them to turn images of waveforms into electronic signals rather than visualise the sounds themselves. Ian's film Practical Electronica contains some footage Fred created of the Chromasonics system in action. below is a full colour image from the cover of Practical electronics. Fred's work on audio definitely inspired wide range of experimenters, I wonder if any visual work by his readers survive. 

Here are some images the construction of the Chromasonics system notice the large colour wheel that synchronised with the refresh rate of the displayed images so as to selectively colourise different signals allowing for multi colour display.

Here are some stills of Chromasonics and the trailer for Ian's film

These are some clippings of the the displays Fred developed.

And finally a few pics of Fred at work creating sound!

Practical Electronica will be screened on Tuesday in London link to the event here

Tele Visions Project

http://televisionsproject.org

great line-up! 

"Commemorate the end of TV with Tele Visions, a series of live and broadcast events interrogating the medium of television on its death bed.

Devised, curated and produced to mark the occasion of the analog switch off around Australia, Tele Visions introduces audiences to the works of more than 100 artists working in the televisual space.

You can tune in live via the Tele Visions website or catch it on the analog broadcast if you live nearby. Box Set will be running 24hrs a day until midnight this Wednesday the 27th, from then on the Tele Visions channel begins a five day long continuous broadcast of artworks made for TV. Box Set is one of five live works commissioned by Tele Visions. Other artists include Lara Thoms, WRONG SOLO, Joel Stern and Pia van Gelder.

The entire broadcast program is now online with more than 120 works from 100 artists scheduled up to the minute each day. You can peruse the program from the Tele Visions website or download the TV Guide which also features short critical essays from Doug Anderson (SMH TV reviewer for 40 years), Sherry Miller Hocking (Experimental Televison Centre) and John Gillies (Video Artist and academic COFA). Pick up a limited edition printed (in glorious pink!) TV Guide at live events at both Carriageworks and Verge Gallery.
Tele Visions (28 November – 3 December 2013) is a project devised, directed and produced by Alex White and Emma Ramsay. Presented by Performance Space as part of the YOU’RE HISTORY, a program celebrating 30 years of Performance Space."

Pia Van Gelder

I have been meaning to post up some of Pia's work for a while now I originally found it through Stephen Jones as she has worked with him in the past (see videos below) she has ome interesting pieces
