VECTOR HACK 2018
I haven't updated in a while (there is still a write up of my amazing signal culture trip last year coming)
But this is too good not to leave a short post about. I am helping Ivan and Derek with their amazing Vector Hack Festival project. Vector Hack is a festival centred around experimental vector graphics using oscilloscopes and lasers. It's happening in over two sites starting in Zagreb on 01/10/18 and ending in Ljubljana on 07/10/18. I will be attending so if you decide to come see you there!
Ivan and Derek have worked tirelessly to make this happen and it's going to be amazing.

Zoran Radovic
Zoran Radovic has been working with pendulums, plotters, lasers and CRT displays since the 1960s. A recent post by an online friend highlighted the fact that his studio is being sold off, I noticed some plotter art on the wall which lead me to check out his great site detailing his fantastic work. www.radovic-art.de he details his various systems building on his ideas and demonstrating how some of his systems work. Please go read his site for more info!
Here are a few more links with some of his work

Mandalamat
Here is the very cool Mandalamat an analogue computer specifically built by Christian Günther to create interesting patterns either using an XY plotter or an Oscilloscope, I have had an XY plotter for a while and made a few drawings using modular synthesizer and function generators but nothing this beautiful!

GEARS / Northlight Video 1973
Some amazing early video art from bobvidpix on youtube, thanks to Peter for the link
"GEARS - Computer Video Art - We made this ditty in 1973, you won't find much earlier combinations of online video mix of 3D computergraphics - especially as this was all done, effects etc. in one live pass. Ed Kammerer got a job at Adage, the first developer of realtime-controllable 3D CAD computers - each filling a midsized room. Like leaving kids in the candy store, they let us take over on weekends and nights to make computer/video art. We ran camera cables to two computer rooms, headset intercoms to each computer and camera operator in both of the rooms and then played with XYZ values and phases on the computers and target/beam on the camera and a mixer/keyer. The music was later custom created by Mark Styles. Credits/Tech - from memory, sorry for mental dropouts - Orville Dodson programmed and operated the AGT 130 Adage Graphic Terminal - Edwin Kammerer assisted and operated the other AGT. Charles Phillips and Andrika Donovan each ran camera and I mixed and tech'd. - We had two black & white Sony AVC 4600 cameras & CCU's and a Shintron SEG 366 switcher - recorded on a Sony EV 320 1" VTR.
The sales director for Adage, George White took this tape to show on a morning network TV show interview during the National Computer Graphic Assoc. tradeshow in NY - the host introduced the roll-in with, " Let's see how a computer works ... "
"The music was composed, performed & recorded by Mark Styles when he was at the Musician's Workshop on Clematis Ave., Waltham. I think it was created on the Arp 2600. After we recorded the multicam video of the computer graphics, Charles brought Mark a video player with this and another piece called 'Lisa' (from lisajous, the math that the computers used for the shapes) and he built the music around the flow of the visuals. I've always felt it was the perfect accompaniment."
"Adage Inc. created the first 3D graphic computer with realtime controls. These huge machines with a dozen racks of binary processors had knobs that controlled motion, dimension and other parameters of the 3D patterns programmed into it. Ed Kammerer worked there and brought us in to spend long sleepless weekends with a camera in each of the computer rooms and live mixing onto B&W reel to reel videotape. Cameras operated by Andrika Donovan and Charles Phillips, with Ed and Orville Dodson at the AGT Terminals, and me at the mix. This clip has the live intercom track, and it must have been made before the term 'crash' was coined - so 'watch out for imminent system collapse!'"
"the other difference, perhaps more significant than 16mm vs. video, is we approached these recordings as jam sessions. There was no set routine, such as a software demo, but instead computer and video operators played and improvised together for the visual mixes we made.
"thanks for your comment. Yes, cameras used for this lisajous and 'Gears' were 1" vidicon tube Sony AVC 4600's, live switched on a Shintron 360 & recorded on a 1" Sony EV 310 (pre-C-format). The computer screens we shot were (approx) 18" vector, oriented vertically, and we would position the cameras over the shoulder of the seated terminal operators, turn the room lights off and go. The cameras had CCU's with target and beam control, which enhanced the ghostly lagging typical of vidicon imagers."

Oscillographic Colourisation Experiments and the Barbican
So the performance at the Barbican went ok Lawrence's performance and the structure he designed were really great annoyingly my oscilloscope refused to work even after Stan very kindly lent me a screwdriver so I could trouble shoot, However I had plenty of equipment to perform with and Lawrence and my performance fed in to each other as we played so it went pretty well. Stan and Dan's performance was really amazing. Thanks to Andi who was also on hand to help capture some film of the performances.
here is a still of Stan performing with Dans visuals which sounded and looked crazy good!
Here are some stills of Lawrence and my performance
And here's what it might have looked like had my scope been working >:(

Iconicamera
The Ionic company was an EMS American distributor for a time until it cloned the VCS3 and keyboard in to a single unit of it's own "design", it had some relatively interesting ideas about marketing, one of it's other products looks to have been a modified TV that acted like a simple oscilloscope a project common on the web these days and a technique utilized from the late 60s in to the early 70s by Paik amongst others.

Alivia Zivich, Nate Young, Steve Kenney as Demons
"Demons evolved from a synthesizer duo into a Visual Music trio with the incorporation of video artist Alivia Zivich. Working under the name "Video Madness" she often used the music of Demons as soundtracks to her analog video experiments. Live performances as a group led to the redefining of Demons as Visual Music."
Demons have produced some pretty interesting visual music and are a rare example of the art form as a live hands on band. Alivia Zivich has also produced some interesting solo work some of which can be found on line. While I love the 'high art' of many of the visual music pioneers I can't help but be attracted to the hands on approach to production, something which I have been attempting recently by playing out more often. I wish I could have caught them on their relatively recent European tour.

Video Oscilloscopes !
Some very expensive digital oscilloscopes have composite outputs, if like me you can't find one cheap there are a few other products on the market to fit the bill.
The very cool Critter and Guitari Video Scope produces colourful NTSC video for $99
Both units give a slightly blocky output unlike a real oscilloscope image but they could both find a home in a hardwarevideo set up. They also eliminate the need for rescanning a normal oscilloscope screen (which has its own charm but demands space and equipment).

For us Europeans the MFB VD-01 Videoscope synth module gives a more traditional black and white PAL scope image for €159.
