A couple years ago I did a workshop for CodeMash on building a portable gaming system based on the Teensy 4.1. This is an incredibly powerful microcontroller development board created by Paul Stoffregen over at PJRC. It’s powered by an NXP i.MX RT1062 crossover MCU with ARM Cortext-M7 running at 600 MHz. Despite its cutesy […]

AVR GCC and AVRDUDE
The Arduino IDE is great for being able to dive right in and spin up a sketch quickly with a minimum of fuss. However, there are some situations where you want to get a little “closer to the metal” – without some of the limitations that come with that ease-of-use. Maybe you want to use […]
AD9833 Waveform Generator
A waveform generator is a handy little tool for stimulating and testing electronic components and assemblies. Any work with filters, amplifiers, or other frequency-sensitive designs can benefit from the insights gained through a controlled signal input. Here’s how to make one for about $30.
ATtiny85 Neopixel Controller
The Atmel ATtiny85 is capable little 8-bit microcontroller that plays very well with the Arduino ecosystem. It also comes in a compact and maker-friendly 8-pin Dual Inline Package (DIP), operates on 5V, and costs less than two dollars – making it a great option for controlling some WS2812b RGB LEDs (aka “neopixels”.)
Naked UTC Time Clock
The DS3231 Real Time Clock breakout keeps extremely accurate time, has a battery backup, and only costs a few dollars. Combine it with just about any microcontroller, a display, plus a simple stand, and you have a custom precision clock that can sit on your desk and satisfy your timing needs in a visually-unique way.
