The Nova Drone:

The Nova Drone is an open source, analog experimental sound and light synth.
It it can be used to create effects ranging from slowly fading drones to chaotic harmonic sequences. It also functions as a complex visual pattern generator when combined with a digital/phone video camera. See the video below for an example of the color patterns generated by holding a camera up to the LED.

The NovaDrone offers 3 channels of sound and light. Each channel has the following features:

-TONE pitch coarse tune 24Hz to 750Hz
-TONE pitch fine tune
-LFO rate .008 Hz (around 1 cycle every 2 minutes) to 750Hz

-sync 1
-sync 2

–ext sync 3
-PITCH modulation
-LFO rate modulation

-TONE square wave
-TONE triangle wave
-LFO square wave
-LFO triangle wave
-PWM square wave
-High current LED out for off board LEDs.

The Nova Drones offers 12 potentiometers, 10 switches, 6 oscillators, 9 oscillator sync inputs, 6 frequency modulation inputs and an epic 15 voltage outputs as well as 3 high current outputs for controlling external LEDs. All of the ins and outs have been routed to a prototyping breadboard at the bottom of the unit which allows for liberal experimentation and development of custom circuits. The prototyping area is especially useful for syncing the oscillators of 2 or more Nova Drones together.
