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
