simple analog video glitch circuit – adapted from a Karl Klomp design

SKU: P006 Category:


the _rupture_ is a compact analog video glitch effect device (similar to a distortion pedal but for video!) available as a pcb, kit or assembled and tested unit. check out the video below to see examples of the effects.

it takes any composite video signal as input and destroys the signal in many interesting and unpredictable ways – due to the nature of analog video glitches for best results you should output this signal directly to a crt tv.


the design is adapted from a circuit created by Karl Klomp. this is a perfect beginner project for anyone getting started with video-art making instruments (but also powerful as part of a larger and more complex signal chain)

this project – like everything in the underscores catalog – is fully open-source hardware – find all the source plus lots more information and guides on the github repo:
