Circuit-bent Archer video processor

My first, and successful, attempt with bending an analog video processor.

This project was a few years in the making – mainly a few years of collecting and holding onto a variety of analog video processors and waiting for the free moment to open up and experiment with them.

For my first experiment, I chose an Archer-brand color processor as those are a dime a dozen, and I could afford to short out the boards or ruin the chips via soldering mistakes.

I opened up to find the board had 3 color chips on it. First item I did was offset the factory setting for image output so I would be able to get more from alterations.
The finished product has four added points of articulation – varying between 5k Ω and 50k Ω . Only used one 10 Ω resistor for one of my points.
It’s now got abilities for field perspective warping, color bleeding, trailing, and offset vertical hold. However, you’re still able to adjust saturation, contrast, RGB elements and luminosity as per original design.

Update: You can purchase this processor as a perk for the Norcal Noisefest XXI funding campaign.
