This is the first run of a new instrument I am building. An 8stringed Synth Driven Guitar, rather than a "Guitar Synth".
As part of my 3month Artist Residency at the Artifactory (April-June 2012) I wanted to learn more about CMOS Circuitry / Boolean Logic particularly using the 4000 range chips AKA Lunetta Chips.
This will be an ongoing project and I hope to have a completely self contained Modular Synth/Guitar hybrid to both perform/interact with and possibly setup as a self playing instrument aswell.
Each module is made in free-form style (Point to point, Space Wiring) where no PCB or prototyping boards are used. Each Module will be based on a 50mm x 50mm format using SIP connectors and Breadboard jumper leads to patch the modules together.

In this video the modules are temporarily affixed to a wooden frame but the Lunetta Guitar will have a grounded wire frame between each guitar neck where modules will be secured.

There first Module Ive made that is driving the motor plectrums in this video is based on the online build notes of the crazy 8Bit Cipher Gate Sequencer circuit from Non Linear Circuits:
http://www.sdiy.org/pinky/data/data.html
Its very playable and rhythmic in a "nonlinear" sense.
Next job is to get more current to the motors (or switch them out for servos) and build an ebow type circuit to vibrate each string independently.

There are lots of Lunetta circuits to be found on the vibrant forums of Electro-Music:
