Audio: Super Glitch Barbie

from SwSw ThrghT, 16.02.09

This is a circuit bent toy sound maker based on a Super Talk Barbie doll voice circuit. It’s very simple and lots of fun! I’ve added a power starve control, a trigger and reset switch to recover from crashes.

Unlike like the more conventional unbendable ‘black blob’ talking toys of this era that simply played one shot samples this kind of toy gets pretty quickly into complete gibberish and phoneme tone loops. The circuit is particularly susceptible to disruption by reduction of supply voltage because the microchip plays a sequence of random phrases to construct the output. Starve the voltage and the data address lines go crazy %~)

To starve a circuit just put a 1K ohm variable resistor in series with the battery. A reset switch may be necessary. Just put a normally closed push button switch in series with the starve pot.

Tip: Clear plastic lunch-boxes with resealable clip lids make excellent quick D.I.Y. project boxes - easily worked, light, sturdy and stylish.
