Unseen footage of Atari Battlezone cabinet production

Gary Ventress at The Arcade Blogger writes about footage of the manufacture of Atari Battlezone arcade cabinets. It comes from inside Atari’s Coin-Op Manufacturing Facility at Sunnyvale, California circa 1980. What you see is the real, day‑to‑day production process behind Battlezone cabinets. The footage shows the later stages of the assembly line, the finishing touches, and packing and shipping. It’s a rare look at how these machines were actually built. Some 13,000 Battlezone uprights rolled off of Atari’s production lines during the production schedule that lasted from August 1980 to March 1981. Check out the video below and definitely read ...

Quartz crystals and resonance

Pieter-Tjerk de Boer provides a primer on quartz crystals and how they are used in electronics: Quartz crystals have been used in radio technology since the 1920s, to build very stable oscillators and to filter signals. In WW2 they started to be mass-produced, back then based on natural quartz from Brazil. Nowadays quartz crystals are still a mass product (more than 2 billion per year, according to Wikipedia), most of which spend their lives humbly clocking a microprocessor. If the alternating current has a very low frequency, the crystal can start moving due to the piezo-effect’s mechanical force: the crystal ...

Halkun on GitHub has posted the fully reverse-engineered and commented source code for the Atari 2600 classic, Raiders of the Lost Ark. The game uses a 2-bank ROM (8KB total) with bank-switching. Bank switching is done through a self-modifying code technique where opcodes are written into zero-page RAM variables and executed in-place. Like all Atari 2600 games, the program is structured around the NTSC television signal — one complete pass through the loop produces one frame of video (~60 fps). The frame is divided into four phases: VSYNC, VBLANK, Kernel (visible picture), and Overscan. Game logic is split across VBLANK and Overscan to stay within the CPU ...

Making ferrite core inductors at home

Daniel Mangum has recently been working on tuning circuits, which typically consist of an inductor and a capacitor (i.e. an LC circuit). For those not familiar with inductors, they are passive components that store energy in a magnetic field. They oppose changes in current, meaning that they pass direct current (DC) and block alternating current (AC). While inductors can be difficult to work with, they are fairly easy to make with basic supplies. Doing so allows you to manipulate the design of the inductor to fit the necessary attributes for your application. Follow along as Daniel makes some air and ferrite core inductors in the post here.

Danny Spencer has made a Game Boy Color game that renders images in real time. The player controls an orbiting light and spins an object. Normal maps are a core concept of this project. They’re already used everywhere in 3D graphics. And indeed, normal map images are secretly a vector field. The reason normal maps tend to have a blue-ish baseline color, is because everyone likes to associate XYZ with RGB, and +Z is the forward vector by convention.

A fairly large subset is supported: global variables, functions, if statements, while statements, lots of operators, pointer dereference, inline machine-code, comments, etc. All of these features make it quite capable.

The Intel 286 CPU is 44 years old

44 years ago, a crafty collection of 134,000 transistors would mark a major inflection point in the PC industry. The Intel 286 CPU was introduced in February, 1982, a 16-bit x86 chip introduced protected mode memory, and would power the IBM PC/AT and a tidal wave of clones. This 16-bit fully x86 software compatible CPU delivered some major performance and architectural advancements over the Intel 8086 and 8088, and would continue to be produced and feature in PC systems well into the 1990s. Development of the 80286 began in 1978, the same year Intel introduced its 8086 CPU. Intel studiously completed six months ...

Pictured above, the iyO hardware, no not that one. OpenAI’s hardware branding is now officially not going to be iyO. Court filings this week confirm the company has abandoned the “io” name for its Jony Ive-designed AI device, won’t ship anything before February 2027, and hasn’t created packaging or marketing materials yet.

Game Boy Advance audio interpolation

jsgroth’s blog writes about an audio enhancement that a Game Boy Advance emulator can implement to reduce audio aliasing and noise, at a fairly high level. There are some alternative approaches to improving GBA audio that produce higher-quality results, such as NanoBoyAdvance’s excellent MP2K HQ feature, but the interpolation approach is notable in that it works with any GBA game (though quality can vary by game). MP2K HQ for example only works with games that use the MP2K audio driver (aka M4A aka Sappy), which is many games but not every game. The core idea behind enhancing interpolation is fairly simple: what if, instead ...

NimBLE-DataPipe: a lightweight BLE transport layer for the ESP32

NimBLE-DataPipe is a lightweight BLE transport layer for the ESP32 by Denis Machard. It allows you to “pipe” both JSON and Binary data over a single BLE characteristic with zero effort regarding MTU limits or fragmentation. Why DataPipe? Automatic Fragmentation: Large payloads (up to 64KB) are split and reassembled transparently. Bi-modal Support: Built-in support for ArduinoJson objects and raw uint8_t buffers. Zero-config: Automatically detects the best MTU for your connection. It’s coded for PlatformIO and under an MIT license. See more on GitHub.

In the course of this work, corners of the 386 microcode and silicon have been examined in detail; this series documents the resulting findings. “…the 386 has a dedicated barrel shifter that completes an arbitrary multi-bit shift in a single cycle. What’s interesting is how the microcode makes one piece of hardware serve all shift and rotate variants — and how the complex rotate-through-carry instructions are handled.” A barrel shifter is a combinational circuit ...

Its task is twofold: displays a notification every time a serial port is added/removed by hovering the mouse, displays the list of available serial ports See GitHub for the Python code and the post here.

We actually tried using an LLM (Claude Opus) to do the design since it’s a simple enough thing, worth trying out after our footprint-generation success. But it’s still out of reach… the design it came up with was sort of gunky and had weird assumptions and mistakes. All good, we had Claude generate the 7-pin terminal block footprint based on ...

Rise of the Triforce in arcade gaming

During the rapid technological advancements of the early 1990s, the video game industry was on the cusp of a massive addition – another dimension. With console shenanigans like the Super FX chip giving players a taste of 3D, hype was at an all-time high. But the games released for home consoles were nothing compared to what arcade developers were capable of doing. But the future eventually arrived with the launch of the 5th generation of consoles. With arcade revenues shrinking, companies did something that would have been considered unthinkable just five years prior. Sega teamed up with Nintendo to develop a GameCube-based arcade platform. ...

Claude reverse engineering a sleeping mask

Aimilios Hatzistamou posts an interesting session transcript interacting with Claude in reverse engineering a wireless connected Chinese sleeping mask. Specific information is redacted to avoid issues, but it remains a very interesting interaction and deep dive into reverse engineering. User: I bought a Bluetooth sleep mask that has massage, vibration, audio, and electrical muscle stimulation of the eyes. And it’s built by this Chinese company. They have this app to control it, but the app is really buggy. And I would like to control it myself using a custom integration. How should I go about controlling it from my computer? ...

The “Crown of Nobles” noble gas tube display

A chance to get more familiar with the behavior of ionized gasses in general, and a desktop scapegoat to glare at when working through propulsion issues. Amazon sells gas tubes just for this purpose!

Diagnosing a Commodore PET video fault from one photograph

Tynemouth Software writes about an owner who had initially made contact saying they had a PET 2001, and there was no video output, and they wondered if bad ROM or RAM could cause that and would a PET ROM/RAM fix the issue? After some probing around, they found the 74177 at D6 was at fault, and replacing that give video sync and a screen full or random characters. Time for a ROM/RAM board. One was order and fitted.

The setup is simple. The Redditor installed the M.2 PCIe 3.0 SSD into a standard M.2-to-PCIe AIC (Add-in Card), the same type typically used to run an M.2 SSD in a PCIe expansion slot. Consequently, the user inserted the AIC into the PCIe-to-PCI adapter, which ultimately plugs into the PCI slot on the motherboard.

Web-based tools for printing separated colors with halftone on home laser printers

riso@home is a set of Web-based tools for printing separated colors with halftone on a home laser printer Risograph printers (and other print processes that use halftone color effects) create beautiful layered patterns of colored dots to achieve a full range of colors from just 4 inks — or even fewer, with creative color mixing. This typically uses color halftone techniques, but sometimes also dithering. Jeffrey Warren writes: We don’t have a risograph printer, but want to do some home publishing, and got a $270 laser printer. Here are some tools to do fun color work with a laser printer!

He cannot tell others what he has seen.” – Sam (Mahasamatman) from his conversation about the nature of religion and enlightenment. In Lord of Light, published in 1967, Roger Zelazny wrote about a swordfight between the Buddha and the God of Death where both combatants quote ancient scripture at each other while trying to achieve philosophical clarity through mutual annihilation.

Read the full opinion (PDF) The Supreme Court ruled 6-3 this morning that President Trump’s use of the International Emergency Economic Powers Act to impose tariffs was unlawful. Chief Justice Roberts wrote the opinion. Thomas, Alito, and Kavanaugh dissented. TL;DR the Constitution gives Congress the power to tax imports. Article I, Section 8. The president has no inherent authority to impose tariffs during peacetime, the government conceded this at oral argument. The entire case came down to whether IEEPA, a 1977 emergency powers law that lets the president “regulate… importation,” secretly included the power to tax every product from every ...

The thing behind the smiley face mask has an unlimited wardrobe to choose from

On Sunday, Anthropic’s alignment team posted up a paper/article that may make many feel deeply uncomfortable. It’s called The Persona Selection Model: Why AI Assistants Might Behave Like Humans and it posits that the AI you’re talking to isn’t answering your question. It’s asking itself who would answer this question, then putting on that character like a costume. The researchers (Marks, Lindsey, and Olah) say during pre-training, the model consumes the entire written history of our species and learns to simulate every persona it encounters… the helpful teacher, the forum troll, the middle manager, the serial killer writing a manifesto. ...

Your Lidar is leaving data on the table; 40x128x33 words worth

The waveforms are screaming and nobody’s listening, that’s two posts with “screaming” for those keeping score. A team from Mercedes-Benz, MicroVision, Torc Robotics, and Princeton just published a paper at ICCV 2025 that could help lidar manufacturers improve the value of their sensor output.

A World Appears by Michael Pollan – A Journey into Consciousness

It started with a bar bet in Bremen, Germany, 1998. Two guys who spent their lives thinking about what it means to be alive got drunk and decided to wager a case of wine on existence of the human soul. Neuroscientist Christof Koch bet that within 25 years, science would pin consciousness to a specific cluster of neurons. Philosopher David Chalmers disagreed. In June 2023, Koch walked onto a stage in New York and handed over the wine to Chalmers. The spectacular failure to pin-point consciousness is the engine of Michael Pollan’s A World Appears, and I think it’s the ...

Time Setter 5000 image via CW&T The Solid State Watch takes a Casio F91-W module and encases it in resin. You can’t access it at all – no extra functions, no time setting and no battery changes. When ordering you select the time zone and display method and that’s it for as long as the battery lasts (hopefully 10 years or more). To streamline production and reduce errors the creators, CW&T, built the Time Setter 5000. It uses a Raspberry Pi and camera to automatically set the time.

An Arduino Telnet server library designed for the ESP32

AsyncTelnet for ESP32 is a high-performance, non-blocking Telnet server library specifically designed for the ESP32 using the Arduino framework. By leveraging the AsyncTCP stack, this library operates entirely through event-driven callbacks. This ensures the main loop() remains unblocked, providing maximum stability for time-critical applications such as sensor polling, display updates, or motor control. Key Features Fully Asynchronous: No polling or loop() overhead; events are handled via background tasks. Flash Optimized: Minimal binary footprint. Single-Client Lock: Automatically manages connection attempts to ensure stable logging. Robust Memory Management: Implements active protection against dangling pointers and network-related crashes. See the project on GitHub under an Apache license.

So today we’re going to try and push Pi cooling further than I’ve ever done before, hopefully getting the Pi’s CPU down to below 10 degrees. At 2.4GHz, temperatures start out at 23°C and stabilize at just 25°C under full load. So, barely any difference between idle and under load. The stacked TEC configuration produced the lowest temperatures overall, but at the expense of ...

Robot LCD display face with a 3D printed LEGO helmet

upir on GitHub has taken a 128x128px 0.85″ IPS LCD display and paired it with an ESP32-S3 microcontroller to provide projection of various faces. A 3D printed helmet is placed over things, making it look like a Lego minifig head (about double the size of a minifig head due to the size of the display, about the same size as a Duplo figure head). See the video below and more on GitHub.

Here’s a look at using Rust for embedded development. The goal wasn’t to convince anyone that Rust was the future of embedded systems. I simply wanted participants to get hands-on experience running Rust on real hardware so they could decide for themselves whether it was worth pursuing.

The DOS memory management was probably written sometime around summer 1982, and it meshed with the newly added process management functions (EXEC/EXIT/WAIT)—allocated memory is owned by the current process, and gets freed when that process terminates. The DOS memory management saw very minimal changes from version 2.11 up to and including DOS 4.0. DOS 5.0 brought somewhat significant changes related to UMB support. ...

Spice86 – A PC emulator for real mode reverse engineering

Spice86 by OpenRakis is a tool to execute, reverse engineer and rewrite real mode DOS programs for which source code is not available. It’s a port, and a continuation from the original Java Spice86. General process: You start by emulating the program in the Spice86 emulator. At the end of each run, the emulator dumps some runtime data (memory dump and execution flow) You load those data into ghidra via the spice86-ghidra-plugin The plugin converts the assembly instructions in the memory dump to C# that can be loaded into spice86 and used either partially or completely instead of the assembly code. This allows ...

A drop-in Arduino serial replacement for ESP32 that sends output to a Telegram bot over WiFi

TelegramSerial is a drop-in Serial replacement for ESP32 that sends output to a Telegram bot over WiFi. It inherits from Print and works anywhere Serial does. Just swap Serial for tg. Each user creates their own free Telegram bot via @BotFather. Your serial output goes directly from your device to your chat — no relay server, no third party, no shared infrastructure. Fully segmented and private by design. Features Drop-in — inherits Print, so print(), println(), printf() all work Non-blocking — queues messages, drains one per update() call Rate-limited — respects Telegram’s API limits automatically WiFi resilient — auto-reconnects, retries failed sends Mirror mode — optionally echo to hardware Serial simultaneously Markdown mode — wrap output in monospace code blocks ...

The Pro-Human AI Declaration: It’s a Start! (but ignores open source)

The Pro-Human AI Declaration has a document and a coalition: Steve Bannon, Susan Rice, Ralph Nader, Glenn Beck, AFL-CIO, Congress of Christian Leaders, SAG-AFTRA, Future of Life Institute, Institute for Family Studies, Center for Humane Technology, Pause AI, Control AI, MIRI, and more. Why did they all sign this? When this many seemingly incompatible people and orgs converge on the same document, it usually means the cause is vague enough to absorb any agenda… Some of this is genuinely good. Legal liability for AI companies, child protection from manipulative AI, off-switches, failure transparency, no regulatory capture (yes, though good luck). ...

The White House Released Its National Cyber Strategy

The White House published its National Cyber Strategy for America this week. It’s fairly short and to the point, six pages long with six ‘pillars’. AI has perhaps the largest role; the era of AI being studied is over, it’s now being deployed. AI language in Pillar 5: “We will rapidly adopt and promote agentic AI in ways that securely scale network defense and disruption.” On regulation, Pillar 2: “Streamline cyber regulations to reduce compliance burdens… ensure that the private sector has the agility necessary to keep pace with rapidly evolving threats.” Talent and Capacity, Pillar 6: We need a ...

We’ve gotten a few requests for alternatives to the popular TDK InvenSense ICS-43434, which just went into last-time-buy mode. We love this microphone ourselves because it’s an all-in-one I2S mic, so it works with a vast range of microcontrollers or microcomputers without needing a separate codec or I2C configuration. Let’s find another I2S microphone, ideally with about the same footprint and 3V logic. See the chosen DigiKey part. Catch the video below:

Raspberry Pi Pico as an AM radio transmitter

Pooya Esfandiar shows how a Raspberry Pi Pico can be used as an AM radio transmitter. Years ago, people figured out Raspberry Pi’s can accidentally double as FM radio transmitters without a need for any radio front-end (if we don’t count a single jumper wire working as an antenna). They achieved this by tying a GPIO pin to a software-controlled clock around 100 MHz to modulate audio. This created a low-powered FM radio transmitter. I wondered if a similar feat could be achieved by much less powerful Raspberry Pi Pico microcontrollers. One of the pins is programmed to produce a constant 1000 KHz ...

Restoring a Sun SPARCstation IPX

Andrew Back posts about restoring a vintage Sun SPARCstation IPX workstation. If you worked in computing in the early 1990s, studied computer science around then, or just had a keen interest in computers, the chances are that Sun Microsystems was a familiar name and their workstations were highly coveted. At this time PCs were fast becoming the standard desktop computer and pretty much all looked the same, while if you worked in a creative industry you might have been lucky enough to use a Mac — but even then, the differences were not so profound However, there was a breed ...

By request: MT6835 magnetic angle sensor breakout, coming soon

A community member asked for an MT6835 breakout… so here it is. This is a high-resolution magnetic angle sensor aimed at motor feedback applications, and it’s got a few more tricks up its sleeve than the AS5600 we’ve carried before. The big differences: SPI instead of I2C, and a much wider output options..S PWM, UVW commutation signals, and AB + Z incremental encoder outputs. That makes it a lot more flexible when you’re building closed-loop motor control systems and need the sensor to speak the right language. We tried to design the board around how these things actually get used. ...

STC31 is a wide-range (0-100%) CO2 sensor

We stock lots of CO2 sensors at Adafruit, but so far all of them are for indoor air quality applications: they’ll tell you the CO2 ppm which ranges from 400 to 2000+, higher means stuffier. But there are some scientific uses for measuring high-concentration CO2. For example, CO2 is used in cold-chain food and pharma transport, warehouses, and breath analysis (exhaled breath has tons of CO2). Since this sensor has less accuracy at the 0 to 5000 ppm range, it’s not as good as, say, the SCD-3x or SCD-4x series for indoor monitoring. To get the best performance, we paired ...

The AD8495 breakout has been popular for a while now — K-type thermocouple in, analog voltage out, done. But some folks needed more. Specifically: J-type probe support, and a version that holds up better when the board itself is running warm. So we’ve got two new ones. The AD8494 reads J-type thermocouples, which show up constantly in older industrial gear. The AD8497 handles higher cold-junction temperatures — better suited for enclosures or setups near heat sources where the AD8495 starts to drift. Both are pin-compatible with the AD8495, same PCB layout, same 5mV/°C output. We just swapped the IC and ...

We don’t expect much in the way of calibration here, but for the price, it might be useful for some folks. It comes in a few different kPa ranges, from 5kPa to 300kPa maximum pressure, it measures the difference between ambient pressure and the port – not absolute pressure like the BMPxxx series!

We saw this part number fly by over the weekend, it’s kinda interesting because usually GPIO expanders can’t read analog voltages, and ADCs can’t turn their pins into outputs. But the ADS7128 chip is neat for being able to have any of its 8 pins be inputs, open-drain or push-pull outputs, or 12-bit analog read. Communication is over I2C so it goes on a STEMMA QT board. One neat thing is that both DVDD and AVDD can be 2~5VDC, but you can have separate voltages and one can be higher than the other; e.g. 3V for power/IO and 5V for ...

Designing an open Agriculture robot for researchers and farmers

The Sowbot Open AgBot ecosystem by Agroecology-Lab is designed to bridge the “prototype gap” in agricultural robotics. It provides a Reference Hardware Design that is accessible to startups and is developing a Production-Ready Software Stack that satisfies the rigorous requirements of research. For startups, this eliminates ~18 months of R&D on the “plumbing” (drivers, networking, UI), allowing them to focus on their unique value (e.g., a proprietary seeding algorithm). For researchers, it provides a stable, repeatable environment where experiments can be shared across labs by simply sharing a Docker image. You can see more on the website and on GitHub.

The balance wheel swings one direction, that’s a “tick.” The balance wheel swings back and the whole thing happens in reverse. That’s a “tock.” A timegrapher extracts three things from this signal. Rate is how far the average beat period deviates from the ideal — expressed as seconds per day.

An interactive intro to Elliptic Curve Cryptography

Over on growing, they’re posting cryptography concepts from a recent university course: Suppose two people want to communicate privately over the internet. They could encrypt their messages, scrambling them so that only someone with the right secret key can read them. But that raises an immediate problem: how do they agree on that secret key in the first place? They can’t whisper it to each other. Every message between them passes through the open internet, where anyone could be listening. One solution is public-key cryptography: each person has two linked keys, a private key they keep secret and a public key they share openly. The ...

Approximating rational and irrational numbers using rational fractions

The lcamtuf’s thing blog examines an interesting mathematical concept – an outcome of an numerical experiment that can be backed up with fairly simple proofs, but that makes sense only if you take a step back to consider the construction of real numbers and rationals. We start by picking a real number r. Your job is to approximate it as closely as possible using a rational fraction a / b with a reasonably small denominator. The approximation can’t be the same as r. Is this task easier if r itself is rational or irrational? The answer is very surprising. See the post here.

Which pens and paper are recommended for plotting?

Dan Catt is creating material on YouTube titled “Drawing Machines for Artists, Coding Course”. In this video, he takes on a question so many people have: when using a plotter, which pens and paper should one pick. Dan Catt is a pen plotter artist, who traverses the boundaries of math, technology and design, to create distinct, abstract artworks. He collaborates with drawing machines and the computer, using code to generate lines, patterns and shapes – interpreting and manipulating the algorithms to ‘breed’ new forms that are aesthetically beautiful.

It’s the first commercial reactor construction approval in nearly a decade, and the first for a non-light-water reactor in over 40 years. The Natrium is a 345-megawatt sodium-cooled fast reactor paired with a molten salt energy storage system that can temporarily boost output to 500 MW. Instead of water under high pressure (every conventional reactor running today), it uses liquid sodium as coolant, which operates at atmospheric pressure and has a boiling point of 883°C.

MS-DOS 2.0 on the Apple IIe

Seth Kushniryk has been porting MS-DOS 2.0 to the Apple IIe using the AD8088 Plus coprocessor card. It’s an 8088 CPU on an expansion card with its own RAM and ROM. The card shipped with CP/M-86, available from nanja.info. The original ALF advertising materials suggest there may have been an MS-DOS port at some point (they write about it in future tense, so I don’t know if it ever actually happened), but the original OS disks aren’t shared to any of the usual places. I decided to start my own port because I like directories and object-oriented Turbo Pascal, neither ...

From 1930 to 1941, Dr. Goddard made substantial progress in the development of progressively larger rockets, which attained altitudes of 2400 meters, and refined his equipment for guidance and control, his techniques of welding, and his insulation, pumps and other associated equipment. In many respects, Dr. Goddard laid the essential foundations of practical rocket technology.

Ken Shirriff explains the history and popularity of terminals with 80×24 and 80×25 displays. A recent blog post “80×25” motivated me to investigate this. The source of 80-column lines is clearly punch cards, as commonly claimed. But why 24 or 25 lines? There are many theories, but I found a simple answer: IBM, in particular its dominance of the terminal market. In 1971, IBM introduced a terminal with an 80×24 display (the 3270) and it soon became the best-selling terminal, forcing competing terminals to match its 80×24 size. The display for the IBM PC added one more line to its ...

The latter half of the twentieth century has seen an unprecedented rise of microelectronics such as optoelectronic sensors and microprocessors. It was during the 1970s when these technologies began to move into consumer products while their use expanded heavily during the 1980s. In 1987, Canon’s revolutionary Electro-Optical System EOS introduced an entire bundle of new electronic features. This new microprocessor-based concept not only created a fully electronic, all-digital interface between the ...

Electric motor scaling laws and inertia in robot actuators

Ben at Robot Daycare discusses electric motor scaling laws and inertia in robot actuators. Here’s an ostensibly straightforward question for anyone who’s spent time thinking about robot actuators. Take a look at the three cartoon actuators (above). One has a large, direct-drive motor, one has a medium-sized motor with a single-stage gear reduction, and the third has a small motor with a a two-stage reduction. The gear ratios are chosen so that the actuators can all produce the same output torque, and all have the same resistive dissipation in the motor for a given output torque. Assume the gears are ...

Exploring reinforcement learning for a self-balancing robot

Maker Shawn Hymel explores using the intersection of robotics, machine learning, and microcontrollers to train a reinforcement learning agent to balance a two-wheel robot in simulation, and then deploy the trained policy to run on an ESP32-based robot. The two-wheel balancing robot is one of those classic robotics problems that has been around for decades. It’s essentially the same problem solved by devices like the Segway: a robot balancing an inverted pendulum on top of two wheels. Traditionally, this problem is solved using control theory. Most implementations use some combination of a PID controller, sensor fusion from an IMU and ...

There are backwards LEDs, floating address lines, cursed EEPROMs, and at one point I just learned to read binary by staring at some blinking lights because I’ve been too lazy or distracted to build an output register yet.

Well, we’re doing sweeps and found it just in time for summer thunderstorm testing season! The antenna (which didn’t render here) can pick up the 500 kHz electrical zap signal sent from thunderbolts and report it over I2C or SPI.

NEW LEARN GUIDE: Adafruit TCS3430 / TCS34303 Ambient Tri-Stimulus Color Sensor #Adafruit Products #AdafruitLearningSystem @Adafruit

The Adafruit TCS3430 / TCS34303 (both names are used) Ambient Light Tri-Stimulus Color Sensor is a modern take on the common ‘RGB’ color sensor: this time with CIE XYZ plus IR diode sensors rather than RGB, so you can match it to your existing color space. It acts a bit differently than the color sensors folks are used to, where there are sensors at wavelengths 437nm (X1), 574nm (X2), 537nm (Y) and 434nm (Z) and then the user is expected to calibrate it against a known color space analyzer for their application. For folks that want something that just spits out CIE and ...

Dead letters: US Postal Service will run out of cash in less than a year

Postmaster General David Steiner told Congress that USPS will be unable to deliver the mail within 12 months unless something changes with their funding or budget. The agency lost $9 billion last fiscal year, $9.5 billion the year before that, and another $1.3 billion in just the first quarter of 2026. From the USPS Q1 FY2026 financial results: “While we are pleased that the holiday quarter was quite strong with regard to service improvement as measured by our on-time delivery scores and other important service performance metrics, we continue to face difficult systemic financial and business model headwinds.” Steiner, a ...

Lucas Pope (dukope on TIGForums) goes into the world of dithering images Obra Dinn renders everything internally in 8-bit grayscale then converts the final output to 1-bit in a post-processing pass. The conversion from 8-bit to 1-bit is handled by comparing each source image’s pixel to the corresponding dot in a tiling dither pattern. If the image pixel value is greater than the dither pattern dot value, the output bit is set to 1. Otherwise it’s 0. The output gets reduced to 1-bit and the viewer’s eye will merge the pixels back together to approximate more bits. It feels a little ...

IEEE Spectrum bids a happy 80th anniversary, ENIAC!

On 15 February 1946, ENIAC—developed in the Moore School of Electrical Engineering at the University of Pennsylvania, in Philadelphia—was publicly demonstrated for the first time. Although primitive by today’s standards, ENIAC’s purely electronic design and programmability were breakthroughs in computing at the time. ENIAC made high-speed, general-purpose computing practicable and laid the foundation for today’s machines.

Like a video game system, they had dedicated graphics and sound chips and cartridge-based software, but they were also programmable and expandable, with peripherals like tape cassette drives and printers.

It’s called the Iron Ring, and if you look closely, you’ll see a plain metal band, with no engraving or school logo. It’s worn on the pinky of your working hand, and drags across every drafting, drawing, calculation, keyboard and surface one touches while working. While it is unobtrusive, it is intended to be a constant reminder of the human lives at risk with each decision. The tradition goes back to 1925, when a mining professor named H.E.T. Haultain recruited ...

A C# wrapper for driving HUB75 RGB LED matrix panels on the Raspberry Pi 5 @raspberry_pi

Pi5MatrixSharp is a C# wrapper for driving HUB75 RGB LED matrix panels on the Raspberry Pi 5 using Adafruit’s Piomatter backend. It is aimed at the “keep my app in C#” case: render however you like in managed code, then push the final frame to the panel through a small native shim. Status Raspberry Pi 5 only Linux ARM64 only Native backend bundled as libpi5matrix.so Tested against Adafruit’s Adafruit_Blinka_Raspberry_Pi5_Piomatter at commit 9ce4965a3fddf5b44c9da6c8dc3738cfe0403028 Stable for the default 2-lane single-output path Experimental for custom pixel maps and multi-lane Active3-style setups until validated on real triple-output hardware by this project Check it out on GitHub.

VisiCalc reconstructed

Serge Zaitsev discusses Visicalc, the first spreadsheet program, and recreating it using C. Spreadsheets rule the world for almost half of a century. I strongly believe that it’s one of the best UXs ever created. Being fairly minimal and easy to learn, it allows users to quickly manipulate data, describe logic, visualise results, or even create art and run GameBoy games. It all started in 1979 when Dan Bricklin and Bob Frankston created VisiCalc, the first spreadsheet software. With a few thousand lines of hand-written 6502 assembly, VisiCalc could successfully run on 16K RAM machines. It quickly became a “killer ...

Batear, a sub-$15 acoustic drone detector using an ESP32-S3

Drones are an increasing threat to homes, farms, and communities — and effective detection has traditionally required expensive radar or camera systems. Batear changes that. For under $15 in hardware, Batear turns a tiny ESP32-S3 microcontroller and a MEMS microphone into an always-on acoustic drone detector. It runs entirely at the edge — no cloud subscription, no internet connection, no ongoing cost. Deploy one at a window, a fence line, or a rooftop and it will alert you the moment drone rotor harmonics are detected nearby. In typical audio processing, the default approach is a Fast Fourier Transform (FFT). However, running a high-resolution ...

Espressif’s ESP32-P4 revision 3.0 and greater converts pin 54 of the chip from NC (not connected) to a power rail (VDD_HP_1), requires a few extra passives, and an updated firmware. Espressif Systems first unveiled the 400 MHz ESP32-P4 dual-core RISC-V SoC in January 2023, and the official ESP32-P4-Function-EV development board was launched in August 2024, with commercial solutions slowly ramping up last year. You’d think the silicon and related hardware would now be frozen, but apparently not. The pin 54 was likely converted from NC (not connected) to VDD_HP_1 to improve the stability of the high-performance digital domain. The old revisions 1.0, 1.1, ...

This architecture eliminates audio dropouts caused by blocking operations like SPI transfers, flash writes, or heavy computation. Audio continues uninterrupted regardless of what Core0 is doing. It supports both synthesized sounds (waveforms, melodies, effects) and streaming from WAV files. PicoSound is not limited to games, it is suitable for projects requiring reliable ...

The author exploits the fact that DNS TXT records allow arbitrary text data and are rarely validated or monitored in depth. By Base64-encoding binary files, splitting them into chunks, and storing them across thousands of TXT records in a DNS zone, the author turns DNS into a distributed file storage system. To make the idea practical, a modified C# port of DOOM (managed-doom) was used so the compiled .NET assemblies could be loaded directly from memory instead of the ...

Arranging 2,016 flip dots into a ring shaped display

Most folks are familiar with flip-dot displays – the yellow ones used on buses and subway trains. They’re usually arranged in square or rectangular grids. Pierre Muth had a different idea: arranging 288 segments of 7 dots each (2,016 flip dots) into a ring shape. I had a pile of used 7-dots segments, with half-bridge integrated circuits to drive them. Can we imagine a non-standard flipdots matrix? What about a ring instead of a rectangle? With around 300 segments, the angle between them drops below 2°, which is good enough to make the circle feel continuous and visually acceptable. I ...

NEW LEARN GUIDE: Adafruit VCNL4030 Proximity and Lux Sensor #Adafruit Products #AdafruitLearningSystem @Adafruit

The VCNL4030 is a handy two-in-one sensor, with a proximity sensor that works from 0 to 300mm (about 12 inches) and light sensor with range of 0.004 to 16,768 lux. We’ve all been there. That thing is close but how close? When you need to measure a small distance with reasonable accuracy, such as the rough height of particularly calm bumble bee, the VCNL4030 Proximity Sensor from Vishay can do that for you. If perchance you also needed to measure the amount of light at the same time, perhaps to let the bee to know if it’s time for bed, you’re in luck! The VCNL4030 can do that ...

STRICTLY CONFIDENTIAL: The 2025 Arduino Open Source Report

I’ve been writing about Arduino for almost 20 years. The annual open source report has become one of those rituals where you can take the temperature of a project that matters to (what was) millions of people. Last year I wrote up the 2024 report and flagged a Russian entity that had become the top library contributor while apparently stripping attribution (Limor’s code) from the translated code. This year Qualcomm and Arduino hid this, or who knows. Don’t worry, this year the story is different but the trajectory is worse. First up – the 2025 Arduino Open Source Report (Arduino ...

Ken Shirriff is back with an illustrated history of IBM’s 4 Pi aerospace computers. Introduced around 1967, the System/4 Pi family was a line of compact, powerful computers designed for avionics roles. The military used these computers in everything from the F-4 fighter and B-52 bomber to submarine sonar systems and the Harpoon anti-ship missile. Other computers in the System/4 Pi family played more peaceful roles in the development of GPS and fly-by-wire flight controls. In space, System/4 Pi computers controlled Skylab, the first American space station, as well as Spacelab, the reusable laboratory flown by the Space Shuttle. Despite ...

New power bank restrictions passed to safeguard international aviation

New lithium battery-powered power bank specifications from the International Civil Aviation Organization (ICAO) will enhance safety and peace of mind for passengers and airlines alike. Following the improvements, these devices will now be limited to two per passenger, and passengers will be prohibited from recharging them during flights. Importantly, crew will be able to continue to carry and use these power banks in line with the operational requirements of the aircraft. The new specifications address emerging risks and became effective on 27 March 2026. See more in this bulletin.

Breaking Enigma with Index of Coincidence on a Commodore 64

Michael Doornbos has been looking at the World War II Enigma encryption machine and how to use computers (like a Commodore 64) to make the computations to break the codes. But what if you intercepted a message and had no idea what it said? No weather report header, no formulaic greeting, no re-sent traffic. Just ciphertext. William Friedman developed a tool for exactly this problem in 1922. It doesn’t need known plaintext. It doesn’t even need to know the language. It measures whether a piece of text looks like language at all or whether it looks like random noise. He called it the index ...

Why so many control rooms were painted seafoam green

Beth Mathews writes: In the summer of 2017, we went on another field trip to the National Park’s Manhattan Project Site in Oak Ridge, TN. In 1942, Oak Ridge, TN, was chosen as the site for a plutonium and uranium enrichment plant as part of the Manhattan Project, a top-secret WWII effort to develop the first atomic bomb. What caught my eye as a designer, as with most industrial plants and control rooms of that time, besides the knobs, levers, and buttons, was the use of a very specific seafoam green, seen here on the reactor’s walls and in the control panel room. ...

Digitizing photos from the 1998 Game Boy Camera

Bruno Rocha is a retro game collector who has built a project to digitally save Nintendo Game Boy Color camera images: Recently, I was able to get my hands on… The Game Boy Camera and its printer accessory. Released in 1998, this “game” turned your Game Boy into a kinda bad digital camera, but certainly amazing for the time. Today, even though the quality clearly sucks, I feel that there’s a certain charm to it that I can’t quite put into words. My primary goal after obtaining these products was finding out how to digitize the photos using modern approaches. The Arduino ...

How does FPU detection work in Intel 80×86 processors?

Michal Necasek at the OS/2 Museum discusses an important PC software issue: how to detect when a math coprocessor is present. While investigating a bug related to a program using floating-point math on a 386SX system with no FPU, I started pondering how exactly FPU detection works on 286 and newer CPUs. Although math co-processors became standard some 30 years ago, on old PCs they were an uncommon and expensive add-on, and a 66 MHz 486SX2 would still have a usable yet FPU-less processor in the mid-1990s. The CPU/FPU interface and FPU detection on the 8086/8088 was discussed before. To recap, ...

ESPectre Human Detector for Feather

WiFi moves in mysterious ways. It is invisible, silent, and odorless. Yet it can be harnessed to detect motion! When someone moves in a room, they “disturb” the Wi-Fi waves traveling between the router and the sensor. It’s like when you move your hand in front of a flashlight and see the shadow change. The ESP32 device “listens” to these changes and understands if there’s movement. This project is an Arduino port of ESPectre on a standalone microcontroller, in this case a Feather ESP32-S3 Reverse TFT. The guide will also show how to use Claude Code to develop the port ...

My DIY FPGA board can run Quake II

Petr Mikheev set out with a challenge: an iteration of an FPGA board more advanced than the previous, which meant soldering BGA (ball grid array chips). Specifically, I wanted a more advanced FPGA – I chose the Efinix Ti60F256 – and more modern memory – IM8G16D3FFBG, which is a 1GB DDR3L chip. The first has 256 pins and the second has 96, both with a 0.8 mm pitch. As it turns out, ordering a six-layer PCB from JLCPCB is significantly more expensive than a two-layer one. This time, the total came to over $100, and the price was nearly the ...

NASA says the Artemis II Optical Communications System, or O2O, will provide high speed communications between the astronauts and the ground crew, and will give us 4K videos from the Moon. It’s safe to say technology has moved on since the days of Apollo, at least in terms of the filming and broadcasting apparatus available to the new generation of lunar astronauts. “At 260 megabits per second, O2O is capable of sending down 4K high-definition video ...

Espressif Systems has a new powerful wireless microcontroller in the works, the ESP32-S31, sharing some features of the ESP32-P4 and ESP32-S3 microcontrollers. The ESP32-S31 is a dual-core RISC-V MCU with one high-performance core with FPU and SIMD instructions, and one low-power RISC-V core, featuring 62 GPIOs, a Gigabit Ethernet MAC, WiFi, Bluetooth, and 802.15.4 (Thread/Zigbee/Matter) wireless connectivity, and more. There’s only one high-performance RISC-V core against two for the ESP32-P4, and the ESP32-S31 apparently lacks H.264 VPU, MIPI DSI, and MIPI CSI interfaces, so its multimedia capabilities are more limited. It’s still probably the most powerful wireless SoC from Espressif Systems ...

The TDA2005 stages (U1A and U1B) are set up to produce a high-frequency AC signal.

Anos – a modern operating system for x86_64 PCs and RISC-V machines

Anos is a modern, opinionated, non-POSIX operating system (just a hobby, won’t be big and professional like GNU-Linux®) for x86_64 PCs and RISC-V machines. Anos currently comprises the STAGE3 microkernel, SYSTEM user-mode supervisor, and a base set of servers implementing the base of the operating system. There is a (WIP) toolchain for Anos based on Binutils, GCC (16-experimental) and Newlib (with a custom libgloss).

Aegis: a fully open-source FPGA, from the silicon up

Aegis is a fully open-source FPGA, from the silicon up. Open-source FPGA efforts have made huge strides: projects like Project IceStorm and Apicula reverse-engineer proprietary bitstream formats, OpenFPGA and FABulous generate open FPGA fabric from architecture descriptions, and Cologne Chip’s GateMate ships a commercial FPGA with a fully open-source toolchain. Where these projects each tackle a piece of the puzzle, Aegis is a full-stack, end-to-end open-source FPGA: fabric generation, synthesis, place-and-route, bitstream packing, simulation, and tapeout all live in one project, designed from the ground up for open source. From HDL to GDS, nothing is behind a proprietary wall. The ...

Running Tesla Model 3’s computer on a desk using parts from crashed cars

David Schütz, to get into the Tesla bug bounty program that invites researchers to find security vulnerabilities in their vehicles decided to assemble a Tesla car computer and touchscreen, booting the car’s operating system. The car computer consists of two parts – the MCU (Media Control Unit) and the autopilot computer (AP) layered on top of each other. In the car, the computer is located in front of the passenger seat, roughly behind the glovebox. The last and most difficult part to order was the cable which connects the MCU to the screen. I needed this because both the computer and ...

Full spectrum and infrared photography

Tim Straubinger dives into full spectrum and infrared photography: A full-spectrum digital camera is an ordinary camera except with its manufacturer-installed UV- and IR-blocking filters removed. This leaves the camera with a bare image sensor that picks up extra wavelengths beyond what the human eye can see. Without any extra filtering, these extra wavelengths show up as additional light contributions across colour channels, depending on the lighting source and the camera sensor’s color filter array pigments. For all photos in this post, I am using my full-spectrum-modded Canon EOS Rebel T6 DSLR, and a very basic lens. To simulate a normal ...

There is some speed penalty and there are many remaining bugs, but with smaller 2D/3D models, the experience is often highly usable. In keeping with the experimental status of this target, the version below is built from our latest development branch.

A single-layer, single-head neural transformer written in PDP-11 assembly language

ATTN/11 is the spiritual successor of Xortran, a neural network that learns XOR with backpropagation in Fortran IV on the IBM 1130 (1965) and PDP-11/20 (1970). The natural next step was to see if those machines could successfully train a small transformer in an acceptable amount of time (a few hours). Architecturally, a transformer is actually a fairly modest extension of a basic neural network. The building blocks such as matrix multiplies, backpropagation, SGD, and cross-entropy are already there. The three new components are: Self-attention: dot-product score between projected queries and keys Positional encoding: learned position embeddings, added to the input ...

John Deere to Pay $99 million in monumental Right-to-Repair settlement

The Drive reports the agriculture manufacturing giant John Deere will pay $99 million in a monumental Right-to-Repair settlement and also make digital diagnostic, maintenance, and repair tools available to third parties for 10 years. While the agricultural manufacturing giant pointed out in a statement that this is no admission of wrongdoing, it agreed to pay $99 million into a fund for farms and individuals who participated in a class action lawsuit. Specifically, that money is available to those involved who paid John Deere’s authorized dealers for large equipment repairs from January 2018. This means that plaintiffs will recover somewhere between ...

While it was a marvel of 1960s engineering, the Apollo Guidance Computer’s functional scope was focused and not in the control loop for every system. Critical environmental and power controls were managed through manual or electromechanical means, such as switches and relays. The Artemis II mission carrying ...

Advanced Mac Substitute is an API-level reimplementation of 1980s-era Mac OS. It runs 68K Mac applications in an emulator without an Apple ROM or system software. Unlike traditional emulators, Advanced Mac Substitute doesn’t emulate the hardware on which an operating system runs (except for the 680×0 processor), but actually replaces the OS — so it launches directly into an application, without a startup phase. Advanced Mac Substitute is a factored application. The backend includes a 68K emulator and should build and run on any POSIX-like system. The frontend is a generic bitmapped terminal abstraction, provided by SDL2 (for various platforms) along with custom implementations for macOS, X11, ...

Touch Pi: a Pi Art Generator (ESP32 Touchscreen)

Fun ESP32 touchscreen project from The Debunker via Instructables: Pi (π) is one of the most famous numbers in mathematics—an infinite, non-repeating sequence of digits that appears everywhere from geometry to physics. But most of the time, we experience π as… just numbers. In this project, I wanted to turn π into something visual, interactive, and alive. I built a standalone touchscreen device using an ESP32 and a 4.0″ display that transforms the digits of π into real-time generative art. Each digit influences motion, color, and geometry, creating evolving patterns that never repeat.

Shri Khalpada writes about the physics of GPS for PerThirtySix: GPS is fundamentally a translation tool: it converts time into distance.

Everything else is about making that measurement precise enough to be useful: accounting for bad clocks, satellite geometry, and eventually, Einstein’s theories. I find it amazing that your phone can pinpoint your location to within a few meters using nothing more than the time it takes light to travel from a few satellites ...

Investigating Split Locks on x86-64

Chester Lam on Chips and Cheese posts about multiple threads/cores accessing memory on x86 64-bit machines. “Split locks” are atomic operations that access memory across cache line boundaries. Atomic operations let programmers perform several basic operations in sequence without interference from another thread. That makes atomic operations useful for multithreaded code. For instance, an atomic test and set can let a thread acquire a higher level lock. Or, an atomic add can let multiple threads increment a shared counter without using a software-orchestrated lock. Modern CPUs handle atomics with cache coherency protocols, letting cores lock individual cache lines while letting ...

The origins of the IrDA infrared communications standard

J. B. Crawford writes on the Computers Are Bad newsletter about the IrDA infrared data standard used in older devices to communicate. In 1993, Hewlett-Packard hosted an industry meeting that kicked off the Infrared Data Association, or IrDA. As a group of HP employees recounted the event, it was a smash hit: there were far more attendees than expected, representing more than fifty companies in both consumer and industrial electronics. Within a few years, IrDA’s membership grew to 150 companies—including IBM, Microsoft, and Apple. Commercial adoption was similarly impressive: in the late 1990s, IrDA transceivers were a ubiquitous feature of ...

NostOS: the Nostalgia Operating System for the RC2014 retro/vintage computer

Dr. Scott M. Baker posts about designing and implementing a new operating system for old computers. there’s already RomWBW and Fuzix for the RC2014, and if you’re not that ambitious, there’s plenty of options for running BASIC directly from ROM. So why implement a new operating system? Well, I’ve always wanted to design my own operating system. Operating systems are often a product of the computers they were designed for. We have HDOS for the Heathkit H8 which is a really cool OS offering support for runtime loadable drivers. We have ISIS for 8080-based Intel development systems with its easily ...

Bee Write Back, a portable journal

Simon Shimel likes to journal but not into a notebook. To solve this problem, I created a simple Raspberry Pi based journal, which I could use each night, entering in the chaos of the day, locking it away once I was done. After creating this, I found that the form factor of the writerdeck was really fun to use, and began developing more apps and functions, including a simple Claude chat client. The case is 3D printed. A Raspberry Pi Zero 2W provides the brains. Total cost less than $200. Check it out on GitHub. And see the video below.

Setting Up a Physics and Electronics R&D Lab

Magne Lauritzen at CERN has posted an interesting method for setting up a Physics and Electronics R&D lab. The majority of this guide applies to any lab doing experimental physics, electronics development, or instrumentation work. Sensor-specific sections are clearly marked. The guide covers equipment, infrastructure, and services. It does not cover lab procedures such as safety training, procurement workflows, or inventory management. Those deserve their own treatment. A proper R&D lab cannot be accommodated in a standard office environment. It requires purpose-built or significantly adapted space with dedicated electrical, gas/vacuum, ventilation, and network infrastructure. Identifying and securing suitable space is a ...

Will Greenberg at wretched.computer writes: This year, my winter madness project was adding the classic game Crazy Taxi to noclip.website, my friend Jasper’s incredibly cool and ambitious “digital museum of video game levels”. noclip.website is such a fascinating project… what makes it truly a museum is that its codebase represents an open source recreation of each of those games’ original rendering methods.

Audio reactive LED strips are diabolically hard

Scott Lawson looks to make audio reactive LED strips, not an easy thing to do: In 2016, I bought an LED strip and decided to make it react to music in real time. I figured it would take a few weeks, but it ended up being a rabbit hole. Ten years later, the project has 2.8k GitHub stars. (Next) was to use frequency domain methods. Collect a short chunk of audio, compute a Fourier transform, get frequency bins, and map them to LEDs. I had 144 pixels on a one meter strip, so I thought, 144 bins, one per LED. ...

Reverse engineering the Amazon Blink Gen3 outdoor camera

On the electronupdate blog, they reverse engineer the Amazon Gen3 outdoor camera. Complex 3 board assembly…. many more parts that I expected. Looking at the top most board three interesting sections. The processor is a proprietary part designed by Amazon. Surprising given how easy it is to buy off the shelf: however, one really unique aspect of this product is its ability to run for two years on a single set of AA batteries. I suspect this design has considerable attention to this fact. See the video below and more in the post here.

How did the computerized airline booking system get started?

Ajitem S. writes about how a conversation on a plane in 1953 set in motion the stack that eventually processes tens of thousands of flight bookings per second, and why that stack is still here. By the mid-1950s, American Airlines was managing reservations on index cards. A booking required a phone call to an agent, who would search physical card racks across multiple city offices, confirm availability verbally, and call the passenger back. A transatlantic reservation could take 90 minutes to confirm. The airline was processing roughly 85,000 reservation requests a day across 50-plus cities. The system was collapsing. The ...

The Virtual Apollo Guidance Computer Emulator

The Apollo spacecraft used for lunar missions in the late 1960’s and early 1970’s was really two different spacecraft, the Command Module (CM) and the Lunar Module (LM). The CM was used to get the three astronauts to the moon, and back again. The LM was used to land two of the astronauts on the moon while the third astronaut remained in the CM, in orbit around the moon. An important part of the guidance system was the Apollo Guidance Computer—or just “AGC” for short. On any given Apollo mission, there were two AGCs, one for the Command Module, and one for the Lunar Module. The ...

An MCP server for MicroPython

There’s been a growing trend to connect Large Language Models (LLM) to various tools and systems. Physical devices like microcontrollers can become quite interesting when running LLMs with attached hardware. So Yusuke Sasaki has implemented an MCP bridge server that allows direct code execution from an LLM on a board running MicroPython. You can control MicroPython (ESP32, RP2040, etc.) via USB Serial or WebREPL from MCP clients such as Claude Desktop, Codex (VSCode), Copilot (VSCode), and Antigravity. Check it out on Switch Science and GitHub. (Japanese)
