Spoiler alert: almond butter isn’t phosphorescent. But powdered milk is, at least to the limit of detection of this homebrew phosphorescence detector. Why spend a bunch of time and money …read more Continue reading Homebrew Phosphorescence Detector Looks for the Glow in Everyday Objects
These days, most of our microcontroller boards come with bootloaders so you can squirt hex into them straight over USB. However, you don’t need to do things this way. If you’re …read more Continue reading You Can Program AVRs From The Commodore 64

Moore’s law isn’t strictly holding anymore, but it is still true that most computing systems are at least trending towards lower cost over time, if not also slightly smaller size. …read more Continue reading Pushing Crates in 8-bit Color
The declining costs of single-board computers has made serious computing power available for even the most trivial of tasks. It’s easy enough to slap a Raspberry Pi onto almost anything …read more Continue reading Audio Playback Toy For DSP Adventures
The Unified Program and Debug Interface (UPDI) is Microchip’s proprietary interface for programming and on-chip debugging, and has become the standard on AVR MCUs after Microchip’s purchase of Atmel. Being …read more Continue reading Turning a Microchip MPLAB Snap Into a UDPI AVR Programmer
Showing images on a TFT or OLED display with a small AVR microcontroller can be a challenge as it requires significant storage space. One solution is to compress the images, …read more Continue reading Squeezing GIFs Into Even Tighter Spaces
One generally reads a data sheet in one of two ways. The first is to take every spec at face value, figuring that the engineers have taken everything into account …read more Continue reading To Turn an ATtiny817 into a 150MHz Counter, First Throw Out the Spec Sheet
Writing an operating system for a computing platform is one of those non-trivial tasks few people actually need to do, regardless of whether it’s for a small microcontroller or a …read more Continue reading KittyOS: Writing A Toy OS For The ATmega168 From Scratch
The Julia programming language is a horrible fit for a no-frills microcontroller like the ATMega328p that lies within the classic Arduino, but that didn’t stop [Sukera] from trying, and succeeding. …read more Continue reading Blinking an Arduino LED, in Julia
