Finished Pieces

Double Barbie


    Two glitched out BarbieKaraokeMachines…one unit.


    The BarbieKaraoke has several inputs and outputs that are hardwired in it’s original form.
    -Mic input which is really an amplified input to the echo
    -Echo output
    -Tape amp in
    -Tape amp out
    -Master amp in
    -Master amp out

    The BarbieKaraokeMachine has two circuit boards. One is the main sound board, the other is a sort of mixing board where all of the signals are mixed together and controls like volume and pan are mounted.
    At the bottom of the main sound board is a row of points that connect to a ribbon cable. This row of points is where all of the sounds leave and enter the board (except for the mic/echo input which is at the top left of the board & the tape amp input which is at the bottom left).
    By disconnecting the ribbon cable and connecting jacks to these points (including the echo and tape in) you can create a audio patchbay.
    Below is a schematic that identifies each point.

    There are more schematics on the BarbieBending page.

    I rewired the boards so that the inputs and outputs could be accessed via 1/8″ jacks and I added volume adjustments to each input. I didn’t use the tape deck ins and outs but may in a future model.

    Then I added two sets of pitch and decay adjustments and four rows of echo glitch adjustments. Each glitch has an ON/OFF switch, an adjustment knob and two banana jack patch points. This allows for modular patching and crossbending but was really designed so it could be used with my mechanical sequencer
    The units can be used independently or can be patched into eachother for maximum insanity.

      […] It was an obvious next step. I’ve dreamed about it for over a year. A modular dual barbie wonder machine. This thing is easily THE most capable piece I’ve made to date. It’s loud, it’s crazy, it processes external sounds, it can be externally triggered, cross patched, fed into itself. It pulses, drones, distorts and screams. I couldn’t wait until it was finished to post info on it… So the page for it is unfinished too. I’ll be adding more pictures, notes and sounds as the piece developes. […]

      Pete. I’m probably not alone in noting that this piece is the one that excites me the most. I’m currently mid-project on a piece based on this design that incorporates a glitched out Boss DS-1, voice-changing circuit and a number of passive mixers that will allow for some great cross-patching possibilities. Of course until I have the money to purchase the pots and knobs it’ll have to remain mid-project. But I’ll send along audio and video once it’s complete.

      Glad you dig the Double Barbie. There definitely are a bunch of things you can do with this thing. The Barbie karaoke is sort of a noise tool kit. It’s basically just a bunch of amplifiers and an echo circuit. Adding mixers and distortion is pretty simple. I look forward to seeing what you come up with. Post it here so that others can see it too!

      Hi there, great site.
      Glad I found it. The Barbie bending is interesting.
      I recently took apart a “Craig” karaoke machine in hopes of finding a PT2399 delay chip to use for a guitar effects project.
      Did not find one )^:
      I found a CD1379 and a CD3197…one is for the TV monitor screen I believe.
      What chip was in your machine?
      Do you have a PIN out for it?
      Thank you
      Terry

      the cd3197 is a clone of the es56030 the circuit have the vcc pin4 and the gnd pin 5-6 at the same place and most of the cap and resistor are the same or close

      the cd2398 from an other karaoke is the same as pt2398

      I wish I could have that knowledge to apply this to my next project. Nice info though. Always interested about Barbie karaoke. Thanks man. Keep the info coming.
