I’m Thomas Thwaites and I’m trying to build a toaster, from scratch – beginning by mining the raw materials and ending with a product that Argos sells for only £3.99. A toaster.
Could humans at any point in history, given the right information, construct an electronic communication network? To test this hypothesis, Substitute Materials will attempt to build a functional electric battery and telegraph switch from materials found in the wilderness, using no modern tools except information from the internet. The telegraph will be a first step towards an ahistorical internet.
I saw the wonderful arduino/processing scope, and thought of many improvements, including:
logic analyzer mode that shows 1’s and 0’s clearly.
use as many pins as will fit on screen (tested with 12 at 800x800, seems ok)
use scope class in your own thing, easy to reuse, and setup any kind of GUI
shows volts, based on scaling settings
This software allows you to get a visual representation of an analog signal using Arduino and Processing. The resolution is 10 bits so this is not like a real oscilloscope but it is still pretty useful. It works by sending values read from the Arduino board (pin 0) to Processing through serial communication.
