"A rough and ready demo of this one off feedback generator I built a while back using a fancy-schmancy Silicon Image iScan Pro!
Availible to order here: https://lofifuturestore.square.site/p...
This unit is capable of producing some insanely intricate and evolving feedback loops on its own and it can also be used as a video processor to colourise and glitch out composite video signals for some very 80s looking posterized visuals.
The interface is simple, the upper part housing the built in preview screen also has directional controls and an illuminated zoom button for controlling the position of the image on screen.
The main control surface features:
-3 oversized 45mm knobs for controlling the Red, Green and Blue levels
-5 small knobs that control brightness, contrast, saturation, hue and sharpness
-6 toggle switches for triggering circuit bends that are wired into the Silicon Image iScan board for some glitch effects!
The unit features a 12V power input a composite output (PAL and NTSC) and a switchable composite input (so you can switch from feedback loop mode to video processor mode without rewiring anything)"
"This feedback generator / video synth is based on a very nice Silicon Image iScan composite to VGA scaler that features analog potentiometers to control brightness, contrast, saturation, hue and sharpness. This is something I have not been able to find on another model of composite to VGA converter and they seem fairly hard to come by.
