This page contains schematics and instructions for bending your Barbie Karaoke machine.
Over the past few years the BarbieKaraokeMachine design has changed a little here and there.
Some have two mic inputs, others only one.
Some have volume limiters, others don't.
The biggest difference though is that some have standard, square ICs (typeA) for the echo while others have a "gum drop" style IC (typeB), which is mounted on a little board that sticks out from the main sound board. This model can be identified without opening the unit by looking at the echo button on the front. Most models say "echo". This model says "echo/delay".
The "gum drop" model functions like the other models but has more glitching capabilities. TypeA makes more pulsing type sounds while TypeB is more sporatic and noisey. Of course it's hard to explain the difference and you'd be better off just finding out for yourself. Below are schematics for BOTH types of ICs. Enjoy.
echo bending BPLEASE READ THIS:
-I refer to point "11" a few times below. I don't know where it is or what I was referring to.... sorry :-P.
-This is an OLD diagram and was made in a hurry for a project I was doing. ALL that I can guarantee is that if you try the connections below you will find some different kinds of effects. I cannot guarantee that the effects will be at all like the vague descriptions. There are lots of variables that probably weren't taken into account when I made this list, different adjustments that could be set differently that will effect the outcome. The descriptions of the effects written below could have had more to do with the volume or feedback setting that the specific points that were connected. That said, there's lots to find.. so use this list as inspiration only and have fun.
