Synthrotek - Chaos NAND DIY Kit

The Synthrotek - Chaos NAND DIY Kit is a do-it-yourself kit for users who are after so called "square-wave" or digital noise generators: this is an analog logic-circuit-based noise generator that will keep on surprising you. ÿ

The Synthrotek - Chaos NAND DIY Kit is a super-modifiable noise generator that will knock your socks off with its sheer amount of sonic potential! Low pulsing drones, random robotic chaos, high-pitched laser sounds – it’s all here in this small package.

A great project to begin your explorations into the world of DIY sound synthesis, the PCB was designed with the beginner in mind. Board-mountable switches, tension-relief power supplies, socketed IC, hands-on knobs and switches for tone control, and a detailed silkscreen PCB to help you solder components right the first time.

The Chaos NAND Synth Complete Kit w/ Knobs includes all of the components that you’ll need to build your own. Powered by 9V battery, an AC Adapter rated at 5-12V 200mA Center Negative polarity can also be used.

The Chaos NAND Synth is our custom modification of the Chaos NAND Synth circuit. 4 Knobs and 4 Switches for ultimate control! Two gating oscillators can be switched on/off and varied. Pitch lets you determine the final output sound and Volume sets the output level. CV Input allows for you to power your circuit off an external voltage source for tons of tones you never thought possible! Feed it ~+4V and let it starve or crank up the voltage to 12V for some serious output power! Use a step sequencer to vary the insanity! CV Switch lets you toggle between CV and Power Supply voltage. On/Off Switch kills the power to the circuit allows for a sick dive bomb / laser sound as the circuit discharges its stored voltage.
