Earlier today I did a livestream on my YouTube channel to attempt using an Nvidia GeForce GTX 1080 on a Raspberry Pi Compute Module 4. As with all my testing, I'm documenting everything I learn in this GitHub issue, which is part of the Raspberry Pi PCI Express Card Database website. It's only been a few hours, but…
aka: how I “accidentally” discovered what I already suspected: optimization methods are at the heart of landing rockets.
Apple AirTags: Arbitrary data can be uploaded from non-internet-connected devices by sending Find My BLE broadcasts to nearby Apple devices. We're releasing an ESP32 firmware that turns the microcontroller into an (upload only) modem, and a macOS application to retrieve, decode and display the uploaded data.
Dmitry.GR: How to reverse engineer a completely undocumented microcontroller. From nothing to a full SDK in one week flat!
The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources.
Here's how I built an ultrasonic 3d scanner that works in the air, using off-the-shelf components.
Ever since hearing about Rob Miles' Bitshift Variations in C Minor , a 4-voice polyphonic 16 minute piece of algorithmically generated music, I wanted to implement it in hardware. Getting it onto just any microcontroller seemed too easy , so I wanted it to run on the smallest µC I could find — the ATtiny4. A while…
I have just released a serial port based Amiga disk and file transfer tool, amigaXfer .
After beginning a compiler for the Apple M1 GPU , the next step is to develop a graphics driver exercising the compiler. Since the last post two weeks ago, I’ve begun a Gallium driver for the M1, implementing much of the OpenGL 2.1 and ES 2.0 specifications. With the compiler and driver together, we’re now able to run…
I made a custom guitar with hot-swappable pickups

For years, Wi-Fi packet capturing in the Mac has always worked reliably out of the box. Unfortunately, packet capturing is now broken in the new M1 Mac.
When we announced the PineTime in late 2019 we couldn’t have imagined how popular of a project it would end up becoming. From the very start, it was evident that this will be a project like no other in our lineup. Following 18 months of intense development, the InfiniTime has now reached a release version, and the…
In a previous article, I discussed my intention of Building an E-Ink Laptop . In this article, I want to introduce EI2030 and how we are building an open-source eink laptop and its challenges.
The most powerful and advanced iPad Pro ever pushes the limits of what’s possible on iPad with the addition of the Apple-designed M1 chip.
Apple today introduced an all-new iMac featuring an extraordinary design enabled by the M1 chip, and the best camera, mics, and speakers ever in a Mac.
Apple today introduced AirTag, an accessory that works with iPhone and other Apple devices to track and find important belongings.
I have been long wanting a PDA of sorts with an E-Ink screen that allows me to read stuff on the Internet without eye strains. But the Kindle really sucks as a newsreader device because the experimental browser never works correctly.
The PiDP-11 is a modern replica of Digital Equipment Corporation’s influential PDP-11 minicomputer. Before, we had a computer on every desk and in every home–and long before they were in every pocket–computers were large, intimidating, and locked in special rooms at universities and corporations. The PDP series paved…
