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.

How Video Post-Production Effects were done in the 80s

Continuing the theme of effects videos, here is a nice one about 80s era video effects.

Dan Bucciano recently posted this fantastic clip to the discussion group so I thought I would share. It's some lovley black and white feedback processed with a color solarizer prototype he designed around 20 years ago.

Synapse by Christian Greuel

"Christian GreuelFake Space Labs / CalArts (1992)

An abstract work of visual music, “Synapse” is a stylized interpretation of the inner senses as they are lifted from a state of despondency to find temporary asylum in a delirious

moment of lucidity. This mindscape takes us on a ride through the turbulence of the psyche using vintage real-time 3D graphics and electronic synthesis technology.

The base graphics were created at Fake Space Labs during an Artist-in-Residency (1991-92) and repurposed for this work in 2003.

McConnell Macro Video Synthesis System

Here is something you don't see every day a Amiga Video Toaster/ Atari Falcon based video synthesizer with multiple other signal paths going on, thanks to Matthew McConnell for the upload!http://www.tecterran.com/sonovista  Not your standard analogue set up and much closer to systems from the mid 90s
