Barbie Bending!
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.
