A short demo video on the Wobbulator. It was originally made in the 1970's by Nam June Paik and video engineer Shuya Abe. I was curious why there wasn't a lot of information out there concerning it since it's such a great piece of equipment. Most of the Wobbulator's source images in this video were either from a camera pointed out a window, or just from straight video feedback.

There is a great detailed writeup with wiring diagrams on the Experimental Television Center's website: experimentaltvcenter.org/history/tools/ttool.php3?id=28&page=1

Addition: I was told by Benton Bainbridge that S. Walter Wright is the artist that called it the "Wobulator" but Wobbulator also seems to be the common spelling, at least at the ETC.

Additional addition: Ollie Williams was inspired to create one of their own of these and it turned out really well..check it out: vimeo.com/24636740

    This is lovely. Presumably the function generator is fairly complex. It looked almost like a modular synth in the shots where it was visible.

    Yeah I'd guess modular synth is a more accurate name..but it is all just a +/-5V workstation with a Doepfer modular area above and then it has to be conditioned to be audio level before it goes to a mixer...I'm not up enough on my synth terminology though.

    Interesting. So you're mainly using a load of LFOs to do this then? Amazing stuff.

  • blair neal plus 1 year ago
    pretty much...i wasn't feeding it anything overly complex, usually just a single wave per axis (vert, horiz and "S")...the really gorgeous stuff is more based off camera feedback and just modulating that slowly
  •  
  • toneburst plus 1 year ago
    Ah, I seee..
    You're getting a kind of frequency/amplitude modulation going on I guess, with the LFOs modulating the base 50/60Hz of the scanline.

    What does 'S' do? Modulate intensity/brightness, maybe?

  • blair neal plus 1 year ago
    S was a little confusing to me, and even the document on the device isn't that great at explaining it..but it does more of a sort of diagonal movement shift..I'd say I used that one the most in these examples..where it kind of seesaws back and forth.

    Probably stands for 'Scan'. The movement of the electron beam across the screen is controlled by two voltage waveforms. One repeatedly scans the beam across the screen from left to right, the other moves the beam down at the end of each line, to do the next line. In a normal CRT, the two voltages are perfectly synched together, but I'm guessing your S control monkeys around with the relationship between the two waveforms by modulating one or both.

    Nope, more like 'sinusoidal'. It's not messing with the voltages going to the electron beam -- it's deflecting the electrons with the magnetic field from an electromagnetic yoke, of which it has three: the one it came with, plus a color yoke and the 'continuous wind yoke' that makes the S distortions. It's such a lovely device and really fun to play with...I need to do another ETC residency. :)

    Thanks for sharing this. Love how organic looking some of the patterns are ...

    As a geek i am out of my depth... As a film maker and animator i can say that this is really nice!
    I love the analog setup and i love how you have to film the screen, it would be interesting to see what effects you get from shooting on different formats such as film or Hi8, and playing with shutter speeds etc
    really inspiring stuff for sure, thanks for sharing.

    I could not find where Paik ever called it a Wobbulator, but instead, the Paik-Abe video synthesizer. the wobbulator was from the BBC (1958)...matrixsynth.blogspot.com/2008/10/wobbulator.html
    either way, the patterns here are very nice.

    The visuals this thing produces is amazing. Would make for a cool audio visualizer...although I guess that's partially what it is!

    Hey Blair,
    Thanks for sharing that wonderful demonstration. And the link to the original documents. Great work!
    I had read of this strategy back in the day but never had seen a demo (you gotta love the internet). Thank you for sharing your creativity with us here on vimeo.
    Cheers John

    This is a great video and an awesome device. I'm interested in experimenting with a television of my own but I noticed you are using what looks to be like the same sony television from the link you provided. Is it the same one or is that model television unique for this modification or can other tube color Tv's work? Thanks!
  • Charlie Visnic plus 10 months ago
    I think I just got my question answered by your video. It appears to be the very same one Nam June Paik built.

    Great video though!
  • blair neal plus 10 months ago
    Yep you're correct..this is the original device...I wish I had the know-how to make my own, but I'm not bold enough to risk electrocution ...glad you enjoyed it though!
