Quantizer
Status: Built My quantizer is based on an Arduino Nano, which reads four input voltages and quantizes them into four outputs based on 12 root pitches and 12 different musical modes. The quantization switch changes the behavior between The quantized note for each input is shown on a seven segment display. The module is based…

Attenuverters and Offsets
Status: Built Pure utilities, this module combines two attenuverters which can scale and offset signals with two offsets which can add or subtract up to 5V from the signal. The attenuverters are normalled into the offsets below. I use this module mostly for converting -5V to 5V signals into 0V to 10V signals, and for…

Joystick Controller
Status: Unbuilt Looking at joysticks online, I thought it would be fun to use a joystick to create a 2 axis controller. The two axes could be used to either pan between +5V and -5V as a CV source, or pan between two inputs allowing it to be used as an audio mixer. Two switches,…

Shift Register Sequencer
Status: Built My shift register sequencer is a clone of Music Thing Modular’s Turing Machine. The sequencer is based around two 4015 shift registers which are connected to a DAC0800 digital to analog converter. A knob on the front allows the user to select between looping the shift register, sending random inputs to the shift…

Lorenz Attractors
Status: Built The lorenz attractors are a dual version of Sloth Chaos by Nonlinear Circuits. Each board has two chaotic low frequency oscillators each with two outputs. The outputs are loosely related, they tend to go high or low together, but often to different extents. The cycle time of each output, between high and low,…
