A Glitch Machine
My final project will be - if all goes well - a physical, analogue glitching machine that can be placed on the scanning bed of any printer to glitch any physical image. I'll attached coloured LEDs and a motor or Servo to shake the image while it is being scanned. I started to put together an Arduino today to see what will work best.
Give it a real world context — an analogue glitch tool rather than a machine. Can be put on to any scanner to create a glitch effect. 3d printed frame maybe?? Instructions for recreation.
I don't know why this image is so squished
this also appears to be squished
I used a photo of my girlfriend that I had in my wallet to try glitching first, and I think I got some pretty positive outputs:
On some of them, myself and Chris moved the image ourselves by hand, so I think either larger movements, or more consistent movements, will get better results. The vibration motor on its own wasn't quite enough, I don't think.
I'm going to try and get the entire machine into a portable form factor, so it can pe placed on to any scanning bed and just start. I'll trying use a button or switch to activate it when its placed down — I tried using an LDR to activate it, but any ambient light will just set it off, so I think a pressure sensitive switch of some sort will work much better.
