100PFB Video Synthesizer
Feedback-centric analog visuals
The 100PFB, which stands for 100% Feedback, is a video synthesizer based around creating a no-input feedback loop by feeding two analog video signal converters into each other and exposing controls for manipulating the image.
The I/O includes two composite video outputs (one for the main mix, one for a mini monitor), a VGA output, an external signal/audio input with on/off, and a 5v power jack.
The main panel includes mix knobs for the red, green and blue channels, ‘pulse’ buttons for each channel, an LFO with on/off and controls for rate, shape, depth, switches to send the LFO to each color channel, image shift buttons, zoom/crop adjustment, basic menu controls, and switches for causing some visual glitches.
The device was built into an enclosure which was painted using a hydro-dipping marbling technique. A mini composite monitor was also painted to match.
Custom built for Adam Kane who does visuals over at the 100% Electronica stream on Twitch.
