Failter 6 by Karl Klomp
When the term “circuit bending” is brought up, it typically applies to audio: going inside a synthesizer or guitar pedal and tweaking it to produce weirder sounds. Circuit bending is so rooted in audio, that the prospect of “bending” video signals is pretty unheard of.
A Place To Bury Strangers is going on their U.S. tour this month with two projectors, fed from a switchbox that has six iPods feeding video into it. The feeds are selectable, so any two out of the six videos can be projected onto the band from behind. Here is a clip from their current tour:
Although this setup is pretty sweet, it doesn’t require any IC chips or internal circuitry other than switches and jacks. So we did a bit of research to find out if there is anyone out there actually making video effects pedals. Like a guitar pedal, but for video.
If you google “DIY video effects” or “Video Mixer Circuit” you will inevitably stumble upon Karl Klomp. Klomp takes video circuitry like mixers and monitors, and alters them to make interactive video effects. Here is an example:
Though it seems that most of his effects are made from existing video mixers, there are a few easy projects that were constructed using one or two IC chips. The AD8072 is even available from Analog Devices, so I might start there.
Check out Karl’s website for more videos and pictures of his projects. Maybe in a few months I’ll have a video effects box of my own.
