A couple of years ago I got the opportunity to work on an FPGA design as part of an embedded Linux system. It was my first time using FPGAs and I found them both interesting and challenging. I recently saw this tweet from @ameellio that sums it Read More …
You can learn: To use a laser cutter, CNC mill or a 3D printer. Programming Arduino, Raspberry Pi, ESP8266. Programming in Python, C or Processing. Build and test analogue or digital electronics, making your own circuit boards. And improve your Read More …
Quite a few things inspired me to make this motor: I’ve been watching Walter Lewin’s excellent 8.02 lectures from his MIT course on electromagnetism, I saw a 3D printed motor on Hackaday, and I’m working on some simple educational science Read More …
The large scale drawing robot project continues… Currently we’re aiming for about 10m wide drawings, moving about 50cm per second. It’s been an interesting journey with lots of opportunity for learning, including: long distance communications over RS485 unit testing microcontroller Read More …
Following last year’s experiments with printing sine waves, I kept things a bit simpler with another 2 (the two on the left). Ben Goodman let me use his amazing press again and even provided ink and paper – thanks Ben!
It was a few days before my talk on the ESP8266 at OSHCamp, and I thought it would be fun to make a hacker’s treasure hunt to run over the conference weekend. Oomlout and OSHPark kindly sponsored the prizes. I didn’t have much time, so Read More …
As part of OSHCamp 2015 I’m running a workshop on KiCad, an open source PCB development tool. I’ve run a few workshops on PCB design in the past and it’s always hard work; either trying to keep everyone at the same Read More …
