Vtech Alphabet Desk

Circuit Bent Vtech Alphabet Desk






Modified toy to generate some unique sounds and textures.  Outfitted with a 1/4" output jack, volume control, output signal LED (red), glitch switch and a dual NAND gate distortion/oscillator function.



I made use of some industrial limit switches to activate the glitches.  I found the lever offered a bit more control in how lightly the switches are activated; particularly with the switch at the top as this activates a loop once depressed and also alters the pitch and can mix up the sounds.  Also, this glitch offers some steady drones.  The switch on the right stutters and repeats the sounds/voices when activated at the same time as one of the Vtech buttons.

The NAND gate effect has its signal routed from two sources on the circuit board, one of them is the audio output signal.  This offers heavy distortion on the voices and sounds.
