Cyberdeck Build: R.A.T.I.S.
I built a Raspberry Pi 3 luggable cyberdeck, with a built-in Geiger counter that measures ionizing radiation.
Fantastic RGB LEDs, and where to find them
This is a short post based on a small and simple lesson that introduces some of my students to a rather fancy “hello world” – controlling Neopixel-style* LED strings. The
What is physical computing?
TLDR: Inventing new things and applying current technology in creative ways will require code, electronics, and vivid imagination: in other words, technical skill and creative thinking are needed together. Creative
January – Programmable Paper Workshop
Much exciting content to look forward to, but among other things is an intro course to programming paper-based devices. This is a natural extension of my Paper Circuit Art course,
Why start coding with Arduino?
Arduino lives between two worlds – it is both programming and electronics rolled into something of both – microcomputers, aka physical computing. This makes one wonder, is Arduino really the
Learning the basics of Arduino on Coursera
For a long time, Coursera and other online learning sites didn’t offer much in the way of electronics courses, and there was particularly little related to embedded electronics. That has
Graph Arduino with Processing!
Having just started getting the feel for programming C/C++ with Arduino, I always wanted to give Processing a shot, being vaguely aware that Processing has the ability to catch serial
