Video Circuit Bending

Rupter 1.0 - 1.4
The rupter! Introducing a from scratch build imperfect device that will kill your video signal. As good as it looks as bad it will react. No, its actually working pretty fine. The hardest part is to keep the signal clean. These chips (AD8072) are basic dual video opamp that are normally used in vcr's to amp or filter a video signal. Its very easy to create a working circuit but when you start bending around you'll notice the lack of stability very quickly. It took me some time to have the effects working without extra noise or no video atall. Also within the power conversion I took out the capcitors that will filter extra noise on the signal. This gives the eventual output a higher gain. all sold... waiting on parts to build some more...

Failter 7.0
Failter 7.0 in commision of Jason Somma, a choreograhper and video artist working in US and Netherlands. The Failter 7 is based on the Alecto vmx-600 video fader. A very basic video device that can lead to more options if you explore or exploite.
There are two main effect selections on the left and right with each 5 selective adds. Above we have two pots with on/off/on switches which will roll the image or distorted the sync. In combinations with the effects beneath you can jam along for a while.

Failter 6
Failter 6. Found new enclosure secondhand from the same seller. The selector failter is based on a datavideo vp528. There's always another output when bending these, i can never find the same effect on another machine. It really reacts on the extention of cables from the pcb. You can bend the image letterly by touching the circuit.
Above are 4 knobs which contain a selected effect, in combination its already ours of fun. The two knobs on the left side with the switches are again main effects but more effective. The right section is a 10 point switcher with modulation effecter. The black push buttons are quick switches and working really well. You can make nice patterns and combinations. The device has a in and a output. And is working as a amp when all effects are off.


Refomp 1.0
Refomp 1.0 actually a better version of the omp 0.1. The 'refab op-amp' is a AD8072 with some pots and switches. Did a rebuild of the circuit with complete unofficial resistors and capacitors combinations. Three effect knobs from which one is not so effective. Three switches to affect the knobs and a audio add.
This one is build for NTSC and working best under 6 volt. If all effects are off it works as a amplifier and gain. Theres also a 75ohms switch on the output to the ground. This affects the device completely and interacts with next device.
This one is build for Dylan Griffith. And im planning to do more of these.

AV5-error 2/3
Panasonic ave5 are one of the better mixers around for bending but also for just mixing video. Often one of the channels will run bad (color shifts, bad black level) and people sell the device 'in perfect shape'. Always check on that if you buy them secondhand.
These two versions where build in commision. The two golden cinch connectors on the box are 2 channel audio in that reacts to the ave5. Its actually straight onto the ram. There are around 32 different effects on each channel, but allot are look a likes. These version have 12 effect each that are good for combinations and are all different in aesthetic.
I put a photo of the pcb so you can see what is connected where. All gray wires are eventually connected to the line audio input of the box with a 1k potmeter between to regulated. The audio needs to be very loud to actually.

Failter 5.0
Failter 5.0 in commision of Levlhed specially build for a gig at Burning man. I started out with a smaller box but keep on finding new effects which lead to new interface designs. The process of finding effects and building it into an interface is the real fun for me. And the interface is even more important than the actual effect. If I have three cool knobs that fit perfect but only have two effects the goal is to find the third effect.
This machine includes a dirty mixer in front of the effect chain. There are three major effects with rotary select knobs and pushbuttons/switches build to play with live. The rotary switch are from a broken panasonic ave-5 and jvc-sv77. You can stil see a part of the pcb. It feels good to recycle electronic parts

Codert 01/02
The Coderts are two portable noisers with two different circuits. One has a circuit from a scart video enchancer. The other one has a television decoder circuit inside like the one I used in the FTG-636 or the failter 5. Order this enclosure at vandijkenelectronica.nl. I think Im going to order more of these. I like the fact that they are stackable.
Both coderts have a 12 rotary fx switch with modulate knob and a ON/OFF switch. THe second one has a pushbutton for quick gritching.

Dehancert
Dehancer 't', inspirered by the Dehancers. Now with bnc connectors that gives it a more proffesional look. Orignal circuit was from a video enhancer and gain device of Video Master VA-140 (thanks Bart). I had to cut the circuit so it fitted into the enclosure.
The knob in the middle is the normal enhancer option of the circuit. The ones on the side are bends with both two different effects. The switches on the front will put the effects on/off and the white buttons are for quick gritching. The switch in the middle is the master on/off.

Failter 4.0
Failter, version 4 and running out of enclosures. Bought 12 of these boxes for a nice prices. The aesthetic of the enclosure, the interface design is maybe more important than the actual outcome. This version is not working proper. The circuit broke or failed when I was build the box and try to reconnect all the bend I had found. Theres still the option to distorted the input video and it has a dirty mixer inside but not all effects are working.
The original circuit was from a Hama VM-518 that has a video fade and a enhancer. It also had a fade to white and black option which died.

AV3-E2

Panasonic AVE-3 are great. I keep on buying these machine because they are really good for audio visual glitching. If you want a AV3-E, let me know. If you want to do it yourself, be my guest! Tricky part would be connecting wires to the smd resistors on the circuit. You need to have good solder skils Do not touch the big chips and do not think you can poke around with the wires, it will break! I broke several units to tell you this. The resistors after the buffers are the only bents in this machine.

This one is sold but I still have 4 unbent ave-3 waiting to get touched...

Failter 3.0

Failter Version 3 is a offspring of the Alecto vmx-500. With four main effects and a dirty mix, plus the orignal vido fade. There's one effects in it that is interesting to me, the field flickering, or its a vertical sync shift, something that makes a sort of scanline in the image and randomly creates bloks of horizantal offset image. I like it because its a minimal and random effect thats actually a bit controllable.

On the right upper corner we see a dirty mix with beside a slider for original fading function. But this would be the unofficial verion of a simple video fader. The pushbuttons correspont with the on-off-on switches above and are just quick pushbuttons. You can adjust the amount of effect with the knob on the top and do so quick gritching.


OMP-01

Omp-01, a standalone circuit based on a video op-amp from analog. The AD8072 is a dual video op amp which can be used in various ways. If connect correctly it will send out composite video at 1.3 volt white value (normal white in video is 1 volt), so good for long cables or bent video signals. Or split one signal into two out.
These chips can be request as sample and send to your home for free!

The circuit is quit simple and complete unofficial, but the controls are more complex. I combined the two amps with each other so they influence each other. If the effects are off you can use it as a fade to (almost) black or a gain up to 1.3v. These chip nowadays run on a single 5v power supply. I used my old sony telephone charger which supplies a neat 5v power. In this circuit I used 1k potmeters, various resistors from 75 ohm to 500 ohm, and some old capacitors. But if you like to try this at home, just grab an old pcb board from a tv for instead and rip out some nice funny looking electronic parts and put it between the lines.
