a rpi0 video-instrument – created in collaboration with Guergana Tzatchkova

SKU: P010 Category:


_recurBOY_ is a stand-alone digital video synthesizer and sampler. it can trigger clips and run shaders to create and manipulate video.

this project is a spinoff from r_e_c_u_r an existing video-sampler i created and maintain. it distills the best parts, aiming to be simpler and more beginner friendly. originally we intended these to be built together with others in group workshop sessions.

  • outputs sd composite video
  • 2 source modes to generate video : sampler and shaders
  • process any source with additional FX
  • control shader/fx parameters directly with 4x knobs or externally with 4x cv inputs
  • process (glitchy) external video through easycap capture card

NOTE: this circuit requires a raspberry pi zero attached to operate – these are not included in any variation im currently distributing so will need to be sourced separately – read this for more info

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:
