Nick Winans shares the story of the nice!nano, a wireless, Pro Micro-compatible microcontroller board he made in his freshman year of college. Over my first winter break in college, I created what I called the Dissatisfaction65, a wireless 65% keyboard inspired by the Satisfaction75. I don’t remember exactly why, but I wanted to try making […]

Michael Forney has been having a lot of fun with reverse engineering lately. I was looking over the service manual for my guitar amp, a Yamaha THR10c, and saw references to a UART header in the schematic, I got excited. I wondered if anything cool was hiding in there. Next to it was a JTAG […]

Arduino CLI JSON Fetcher (PHP) is a simple tool that executes a command in PHP arduino-cli board listall --json, saves the retrieved JSON as “raw” and “formatted,” and outputs the formatted JSON to standard output.

John Gregoriadis wired a live C. elegans connectome into the control loop of a Claude coding agent, then watched what the worm did when the code broke. It’s C. elegans, a roundworm about a millimetre long. It has 302 neurons, and scientists mapped every single connection between them back in 1986 (the year I was […]

In 1980, Intel introduced the 8087 floating-point chip, a co-processor that made floating-point operations up to 100 times faster. This chip was highly influential, and today most processors use the floating-point standard introduced by the 8087. Ken Shirriff takes a deep dive into this fascinating chip. The 8087 uses complicated algorithms to accurately compute functions […]

Emily Velasco had recently been tagged in posts about a European feminist hacker collective that was making circuit boards out of clay they dug out of the ground and fired in a campfire. After having an epiphany about some experimental copper ceramics glazes i made last year, i thought i would see if i could […]

I recently got a new phone after my old phone spontaneously leapt out of my hands. It had been generations past due, so I expected some juicy new bells and whistles. I was immediately struck by how unremarkable this new phone was. Gone are the days of generational leaps in design or function; for the […]

Chris Lewis has announced that the game Snowboard Kids 2 is completely decompiled! All of the game’s functions have now been implemented in C and compile to assembly that matches the original game. There’s still some occasional __asm__ hackery, and plenty of code needs better names and documentation, but every function now has a matching […]

CNLohr on Youtube says “What can you do with DMA, a timer and an ADC in a $0.12 ch32v006 microcontroller? Turns out… a lot. Using the technique used by sampling scopes, we can help an ADC bat wayyyy above its pay grade.” See the video here. Code for projects based on the CH32 are on […]

Fabien Sanglard describes the steps to re-create the experience of building the win32 binaries of Quake as it happened in 1997. The purist’s corner Depending on the level of historical accuracy you want to reach, you can follow the steps with four environments. Find an Intergraph RealizM Dual P6-200MHz workstation (good luck). Find a dual […]

OpenRidingController is a horse riding game controller for the PC/Mac. The idea is to emulate basic horse riding behaviors and converts those to work a variety of video games. The controller mainly uses RP2040 Zero, TCRT5000 IR modules and 3D printed parts. Code uses CircuitPython 10 for fast prototyping, later revisions may move to Arduino C or something similar. Currently […]

Floppy disks are several decades old—many of the disks are degrading and the data stored on them is at risk of being lost. In response, Leontien Talboom, a technical analyst at Cambridge University Libraries and Archives, led a roughly year-long project preserving floppy disks called “Future Nostalgia,” which concluded in January. IEEE Spectrum spoke to Talboom about her work preserving data from Cambridge’s collection […]
