"I built a small FPGA microcomputer for the Papilio Pro board. I’ve ported a few operating systems to run on it. These 8-bit machines have very minimal features but (somewhat unexpectedly) I found they can run a multi-user, multi-tasking UNIX operating system."

"It’s been an awesome project to do, and I would do it again in a heartbeat. I’ve still got some tidying up with cable routing, etc, but it has had it’s first run with a pen zip-tied to the Z-axis. The results are pretty good, and the accuracy is nice to see."

"Stepper motors are everywhere! They’re pretty easy to find in old abandoned printers. They come in a variety of configurations and number of poles but they all make great electrical generators! Any electric motor will also output a voltage when it’s freely spinning."

"The hardware is based on Microchip’s Low Pin Count USB Development Kit for the 1814K50. It is setup with 10 inputs, each with a pull-up resistor. The firmware is programmed with USB Human Interface Device Keyboard example from Microchip Solutions. It requires no drivers or special setup, it is plug and play."

Did you know that FPGAs and CPLDs allow you to design hardware inside of them that operate entirely in parallel? This week, we explore this topic in Lesson 7: Parallel Hardware as part of our new PyroEDU course: An Introduction to CPLD and FPGA. Here’s a short overview of the lesson:

"A powerful tool of CPLD and FPGA design is being able to create multiple modules that perform operations in parallel. Let’s explore how this is done and why it is so awesome. "

"Essentially, I wanted to be able to control a little robotic arm / turret using a PC with a serial port. I thought this was a worthwhile project because I could later adapt it to aim a webcam, Nerf toy gun, or maybe even a felt pen so it could draw pictures."

"From Dec. 11th to 21st, I had my first residency at STEIM. I arrived with a number of turntables and hardware equipment to go further with my idea of building an instrument consisting of 8 turntables that are controllable by one unit to use them as an instrument."

"Here’s a cheap way to build your own fully customisable infrared PC remote control. If you already have a suitable infrared remote control going spare you can build one of these for under £4, it will allow you to use most infrared remote controls to issue keyboard commands on your PC."

"This is development board designed by me for the ATmega8 microcontroller. It is a miniature ARDUINO. You can burn your bootloader and then use with Arduino IDE or you can simply upload your hex file using DAPA programmer circuit."
