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.

Mars an Optic Aspic

From youtuber electromedia

 "Bill Etra's real-time live performance from The Kitchen in 1968 was recorded on Color 16mm film by Woody Vasulka. Woody had that film transferred to DV in 2003, and sent one to Bill. Eventually, Bill gave me a copy of the DV with the hope that I could restore MARS to something similar to its original incarnation. Mars an Optic Aspic was originally performed on 9 B&W monitors, but the 16mm film added some unexpected and welcome color effects that lend themselves to the composition. The choice was made to leave them in. So, this is my restoration (and color correction), with no change to the original sound, and for the first time since the original performance we can see the work in a 9-way split."
