Shift Register Sequencer
Status: Built My shift register sequencer is a clone of Music Thing Modular’s Turing Machine. It plays random sequences based on shifting binary values, but can be looped once you find one that you want to stick with.

Infill Housing Analysis Idea
Multi-unit infill housing is becoming very popular for developers in Calgary, but are the prices of the new individual units more or less affordable than the former residence which was bulldozed? Idea: Analyze the pre-teardown sale price and post-construction sales prices to determine if infill housing is driving inflation of prices at a housing-unit level.

Norbert Wiener on Entropy’s End Game
In a very real sense we are shipwrecked passengers on a doomed planet. Yet even in a shipwreck, human decencies and values do not necessarily vanish, and we must make the most of them. We shall go down, but let it be in a manner which we may look forward to as worthy of our…

Norbert Wiener on the Probability and Entropy of Information
Messages are themselves a form of pattern and organization. Indeed, it is possible to treat sets of messages as having entropy like sets of states in the external world. Just as entropy is a measure of the disorganization, the information carried by a set of messages is a measure of organization. In fact, it is…

Norbert Wiener on Information and Modern Life
Information is a name for the content of what is exchanged with the outer world as we adjust to it, and make our adjustment felt upon it. The process of receiving and of using information is the process of our adjusting to the contingencies of the outer environment, and of our living effectively within that…

Norbert Wiener on Information and Entropy
The commands through which we exercise our control over our environment are a kind of information which we impart to it. Like any form of information, these commands are subject to disorganization in transit. They generally come through in less coherent fashion and certainly not more coherently than they were sent. In control and communication…

Norbert Wiener on The Human Use of Human Beings
It is the thesis of this book that society can only be understood through a study of the messages and the communication facilities which belong to it; and that in the future development of these messages and communication facilities, messages between man and machines, between machines and man, and between machine and machine are destined…

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 to different extents.

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.

Sample and Hold, Noise, and Slew Limiter
Status: Built My sample and hold and slew limiter is based on Moritz Kleins design for an analog sample and hold circuit, however I made a couple of tweaks to the design.
