Circuit Bent Elmo

This Elmo turned out great.

This Elmo has had the following improvements:

• Pitch Control (Red Knob)
• Pitch Control Switch: ON/OFF(ON)

• 1/8" Audio Output Jack

• Audio Selector Switch (Internal Speaker/Audio Out) 
•  Power Starve (Blue Knob)

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.

Casio SK-1 Video

Here is a demo video of the Circuit Bent Casio SK-1.

Circuit Bent Casio SK-1

A true classic keyboard from the 80's.  This circuit bent Casio SK-1 offers a huge range of sounds and textures.  This is truly a must have instrument for any studio or live performance; as long as the sounds suite your music taste :).

This one will be offered on eBay once I get the video posted and some sound samples loaded.

Stay tuned!

Circuit Bent YAMAHA PSR-22

Latest keyboard bend, Yamaha PSR-22.

This keyboard is equipped with 15 modifications.

• FM data line modification
• Body contact points
• Glitch switches
• Loop switches
• Distortion Switches

Keyboard is fully functional in its original condition.  The Yamaha PSR-22 has on board effects, pitch control, custom  drum programmer and digital synthesizer.

With the modifications to this keyboard endless sounds and random noises can be generated.  This keyboard also goes into a loop and plays on its own (Rhythm and Orchestra sections).

New Projects for May

I have been to many yard sales recently and have some ground work for new projects.

Up coming:  Circuit Bent VTech Alphabet Desk and a Yamaha PSR-22

Back by popular demand, I have made a new batch of Atari Punk Consoles.  Blinky and Inky versions to be posted on eBay soon.  Check them out!

Circuit Bent Yamaha PSR-11

I have started a circuit bending project for a client.  The modification of a Yamaha PSR-11 with the request that the unit deliver a particular sound under tweaking of glitch switches and mixed data signals.

Sample video to get a feel for some of the available sounds this synthesizer can deliver under the influence of my copper wire, switches and solder.

 May 1, 2011

Project is complete.  This project included a data line cut on the YAMAHA YM812 chip (8-switches) and 9 other glitch modifications.  Glitch modifications included, feed back, body contact, increased tempo on rhythm and other sounds and 6 other bends centered on altering the sound from this machine.
