Exciting news just announced:

Mozilla and Adafruit bring Web Serial workflows to Firefox

As part of this week’s launch, Adafruit, one of the internet’s most beloved open-source hardware communities, is collaborating with us to test and validate what browser-based hardware development can look like in Firefox with Web Serial support.

If you’ve ever spent time with CircuitPython, browser-based board programming, custom controllers, sensors, classroom kits, STEM homework assignments, or a desk covered in blinking microcontrollers—you probably already know Adafruit.

With Web Serial support in Firefox 151, Adafruit’s browser-based hardware workflows now work directly in Firefox as well, with no additional software or complicated setup required for many projects. We invite you to give it a try.

Different communities care about different browser experiences. Some people want simplicity, familiarity and productivity. Others want flexibility, customization, and tools that support the way they work, build, experiment, and create. We want the web to be open, flexible, and shaped by the diversity of people building on it.

If you’re wiring up your first board, experimenting with hardware projects, or dusting off an old electronics kit, give Adafruit and Web Serial in Firefox a try.

Build something amazing. Make something useful. Tell us what works. Tell us what breaks. Most of all, make it your own.

More details available here!

Download Firefox here!

Service outage incoming! No Workshop livestream today. We’ll be back next week.

Join maker John Park in his workshop each week except for when his daughter graduates university!

John Park’s Workshop — LIVE” is the place to see creative projects come to life, as John uses a wide variety of tools and techniques to make everything from video game controllers to synthesizers to LED dance shoes to coffee robots, using digital fabrication, hand and power tools, microcontrollers, and more. Come on into the chat to participate in the fun! Every Thursday @ 4pm ET/1pm PT!

Hello,

I watched the Pi Zero YouTube video you put up about mean people. It made me very “happy” because I got to see the real people who work at Adafruit.

So, thanks for being chill and for all the hard work you do. Thanks to your company, I have a hobby that I really enjoy.

The Creatures of Thought blog discusses the early days of Apple Computers.

By early 1980, the Apple II, which had trailed the Commodore PET and Tandy/Radio Shack TRS-80 at first, had become a remarkable success, with a great deal of help from Personal Software’s VisiCalc. The Apple IPO at the end of the year ratified that fact, minting hundreds of new millionaires.

In 1984, thirteen computer magazine editors unreservedly recommended the Apple IIe as the best computer for schools, because of the “tremendous body of interesting and innovative educational material available for the Apple ranging from real-time science experiments to special keyboards for preschoolers.” Up to now I have largely avoided this key point: what was the “educational material” that students were using? What were computers doing in classrooms in the first place? Who (other than Steve Jobs) thought they would be useful there, and for what?

See the full history in the well-written post here.

If you missed this week’s livestream of John Park’s Product Pick of the Week, not to worry, here’s the video. This week’s pick is the TMAG5273 (A1 & A2) 3D Hall Effect Magnetometers!

The The Virtual OS Museum by Andrew Warkentin is a virtual museum of over 1,700 operating systems (and standalone applications) running under emulation, implemented as a Linux VM for QEMU, VirtualBox, or UTM.

A custom emulator-independent launcher is provided, and all OSes and emulators are pre-installed and pre-configured. The launcher includes a snapshot feature to quickly revert broken installations back to a working state. Hypervisor installers and shortcuts to run the VM on Windows, macOS, and Linux are also included.

Want to see the earliest resident monitors? The ancestor of all modern OSes (CTSS)? The earliest versions of Unix? The first OS with a desktop metaphor GUI (Xerox Star Pilot/ViewPoint)? Early versions of mainstream OSes? If you want to explore historical OSes and platforms without having to worry about configuring/installing emulators and OSes or corrupting emulated installations, you’ve come to the right place.

Just about every well-known OS and platform (and also a lot of obscure ones) is included in some form, spanning the entire history of stored-program computing from the Manchester Baby of 1948 (the first stored-program computer) to the present day.

The catalogue covers, among many other things:

• The earliest mainframes: Manchester Baby test/demo programs, Mark 1 Scheme A/B/C/T (the earliest examples of system software that could be considered as an OS), various EDSAC software, etc.
• Later mainframes and minicomputers: CTSS, MVS, VM/370, TOPS-10/20, ITS, Multics, RSX, RSTS, and more
• Workstations and Unix variants: PERQ OSes, SunOS, IRIX, OSF/1, A/UX, NeXTSTEP, Plan 9, various BSDs, plus Linux distributions across the decades, and more
• Home computers: various CP/M variants, Apple II, Commodore 8-bit machines, Atari 8-bit, MSX, Tandy TRS-80, BBC Micro, ZX Spectrum, Sharp MZ, and more
• Personal computer operating systems: various DOS variants, OS/2, BeOS, Windows from 1.0 to early Longhorn betas, classic Mac OS through Mac OS X 10.5 PPC, and more
• Mobile and embedded: PalmOS, EPOC/Symbian, Windows CE, Newton OS, early Android and iOS where emulation permits, QNX, etc.
• Research and obscure systems: ZetaLisp, Smalltalk environments, Oberon, Plan 9, and many more that few people now have ever booted

If a working version of an operating system exists somewhere, the goal is to have it here, in a form anyone can run on a reasonably modern laptop/desktop.

See it all on The Virtual OS Museum.

While the internet is full of tutorials that tell you how to blink the on-board LED or read a sensor, this board is hiding some surprisingly capable networking capabilities that most people never explore.

You can fix Wi-Fi deadzones with just $5 and 15 minutes of your time, check device presence, even block ads, using nothing but a single ESP32 board. It’s got the right hardware for the job, and with a little bit of tinkering, you can turn that into a surprisingly useful gadget to have around the house.

Check out five ways to use these types of boards om Make Use Of.

Hiro on Reddit posts a ultrawide display cyberdeck:

This is my first cyberdeck. I’ve been working on it for around a month.

It features a Nuphy Air60 v2 keyboard, a Waveshare 11.9 display, Raspberry Pi 4 and a USB Hat powering the whole thing with two 18650 batteries.

The interface is a customized tmux with a custom login screen.

The case was designed in FreeCAD.

See more on Reddit. Via hackster.io.

ScuffedBits on YouTube takes a look at displays salvaged from broken laptops. While the devices don’t have connections to make them immediately useful, one can get aftermarket adapter boards and put the panels to use in creative ways.

it refuses cold, sharp, and academic words at the point of generation. the form and the content say the same thing. the text gives the computer a different personality, less command line, more daydream. the glitch is intentional. the screen stutters, the text flickers, the poem arrives in pieces. small machines should be allowed to be imperfect.”

Light-Up Angler Fish Embroidery

This is a very simple FLORA project with no soldering– a single NeoPixel lights up on an embroidered angler fish on a pair of shorts. The main board is stitched on the front of the design, in the belly of the fish. A snap is used on the fin as a digital switch, triggering a color change in the pixel in the angler’s lure. Follow the circuit diagram to stitch up this circuit, and tuck the battery in the pocket.

This basic project can take you far– try changing up the code to animate the pixel or add more snap switches! We hope this introductory project will inspire your own wearable electronics project.

Hisabumi Hatsugai has tried implementing virtual memory using two MC68000 chips.

The MMU was configured using SRAM. There were two SRAMs: one was TransRAM, which converts logical addresses to physical addresses, and the other was AccessRAM, which records access to physical pages (read/write).

• The logical space is 8 Mbytes, ranging from 0xFF800000 to 0xFFFFFFFF.
• The page size is 4 kbytes.
• TransRAM converts 11-bit logical page numbers (A12-A22) to 8-bit physical page numbers (see block diagram).
• In TransRAM, physical page numbers 0xFE and 0xFF represent page faults. Accessing the logical page containing these values ​​asserts the page fault signal PGFault.
• In AccessRAM, bit 7 is the access bit, and bit 6 is the so-called dirty bit, indicating that a write operation has occurred. The remaining 6 bits are unused and are saved during updates, so the operating system can use them to record information about the physical page.

The two MC68000s are referred to as MPU[0] and MPU[1]. Their respective control signals are also distinguished by adding numbers, such as AS0# and AS1#.

MPU[1] performs normal processing, and if a page fault occurs, it switches to MPU[0] to perform page replacement. The controller switches between the two MPUs.

The controller asserts BR0 and HALT1 upon reset to stop both MPU[0] and MPU[1]. Once BG0 and AS0 confirm that MPU[0] is stopped, HALT1 is negated and MPU[1] is started.

Temuri Takalandze on abgeo.dev looks at a smart doorbell bought on Temu.

Recently I bought a smart doorbell off Temu, the Chinese marketplace that has been gaining popularity worldwide over the past couple of years. I wanted to know how secure the cheap connected hardware sold on that platform actually is. The unit ships under the name “Smart Doorbell X3” and pairs through a mobile app called “X Smart Home”. Camera, microphone, two-way audio, sub-GHz indoor receiver. The kind of gear that has quietly shown up on a lot of front doors.

By the end of a few weekends with one I could:

• silently steal any of these doorbells off its owner’s account
• impersonate the device on a live call, with attacker-chosen video on the owner’s phone
• lift the home WiFi password through a debug port behind a screwdriver

$12 on the front. Whole-network compromise on the back. The first of those takes a free account on the platform, and redirects every real call from the door to my phone instead of the owner’s. The second takes nothing at all, and invents new calls into the owner’s phone with whatever video I want. The real doorbell stays online either way and never knows. You are basically paying $12 to let anyone on the internet ring your doorbell.

See all the details in the post here.

Patten Studio features Flagscape, the 15’ kinetic sculpture installed last spring on the corner of 42nd Street and 6th Avenue in New York.

… We wanted to take a deeper dive into the technical work that brought Flagscape together. We sat down and had a chat with the design team to talk about the plot twists and the “discoveries” we made (i.e. surprises) while working on this project, and the clever engineering our team pulled off to build a 15’ tall kinetic artwork with 6 unique rotational axes that spin 360° 24 hours a day 365 days a year and never collide.

The resulting design decision was to balance each panel on a bent tapered tube that would resemble an abstracted tree branch. “Something I learned designing the tubes is that you can’t really bend and taper hollow metal at the same time,” shares Design Engineer Doreen Chin.

To get around this, the poles were fabricated in parts that were then welded together; the bottom part got bent, and the top part got the taper. Because there’s only 4″ of buffer between Flagscape’s panels, Patten Studio worked with a specialty metal fabricator to get the bend radii perfect, using CNCed templates to check the dimensions.

This is a scientific BCD calculator that uses binary-coded decimals, the same internal number format HP used in its scientific calculators going back to the 1970s. It represents every decimal digit as a 4-bit nibble, which means perfect decimal accuracy, no floating-point conversion errors, and an architecture that is genuinely shaped by the problem it solves.

To make that work cleanly, we also design a custom CPU that thinks in nibbles too. It runs on an Altera Cyclone II FPGA, synthesized with Quartus, simulated with Verilator and ModelSim, and debugged through a Qt-based desktop prototype that also compiles to WebAssembly if you want to run it in a browser. Several tools, several moving parts – all built in stages and tested at each one.

Across ten chapters, you will follow full arc: the architectural decisions and tradeoffs, the numerical algorithms (addition, multiplication, CORDIC for trig, logarithms), the custom CPU design and its 12-bit instruction set, a hand-written two-pass assembler in Python, the microcode that runs on that CPU, a scripting layer for high-level key functions, and finally the physical board with its battery, display, and keyboard. Each piece depends on the last, so we build them in order and test them before moving on because a calculator that returns wrong answers is considerably worse than a calculator that returns no answers at all.

While it is in the name, you don’t actually need a Raspberry Pi to protect yourself from ads. Pi-hole will run on any hardware that meets the minimal requirements and is running one of the many supported operating systems. Switch and Click uses Docker to turn an old computer into an ad-blocker for the whole network.

Pi-hole is THE go-to way to block ads across every device on your network, and it turns out you don’t even need a Raspberry Pi to run it. Here’s how it went for me.

Be on Reddit next Thursday 21st May, 3–5pm BST to see Eben Upton (CEO), James Adams (CTO of Hardware Engineering), and Gordon Hollingworth (CTO of Software Engineering) at Raspberry Pi. They will answer your questions, with a focus on industrial and embedded use of Raspberry Pi.

Between the three, they will cover the full stack, so bring whatever you’ve got; board-level hardware questions, software and OS questions, the Compute Modules, RP2040/RP2350, real-time performance, interfacing with industrial protocols, or broader questions.

NEW PRODUCT – Machined Red Aluminum Servo Arm – 1.75″ Long

If you’ve bought a servo from us, you probably got a bunch of plastic add-ons that you can snap onto the servo’s rotating shaft. These are called ‘servo horns’ and the standard ones you’ll get are plastic pieces. They’re good but often short and not very strong plastic.

This Machined Aluminum Red Servo Arm lets you bring your A-Game to servo projects. It’s made out of strong anodized aluminum, looks great, is easy to install, and will last for a long time.

The servo arm is ~57mm long, and the arm part is 4mm thick aluminum. It has three tapped 2.5mm screw holes and a 3mm screw hole on the end (M3 compatible). The holes are 32mm, 38mm, and 45mm from the center rotational point.

The center part mates with 25-tooth servo axles. We’ve found it’s compatible with our standard-size servo motors:

• Continuous Rotation Servo – Feetech FS5103R
• Standard Servo – TowerPro SG-5010
• Standard Size – High Torque – Metal Gear Servo

But it will not fit neither the Parallax Feedback 360 Degree High Speed Continuous Rotation Servo nor micro and sub-micro servos.

Adam Hughes writes about the sensors contained in modern smartphones and how they can be used, especially with web browsers.

Your phone is dense with sensors. Cameras and microphones, of course, but also accelerometers, gyroscopes, magnetometers, ambient light sensors, GPS, Bluetooth radios. Most of them are accessible from a web page — a single HTML file, no app store involved. I built a series of small demos to see how far you can get with just <canvas>, the Web APIs, and a couple hundred lines of JavaScript each.

Each demo is one self-contained file. Open it on your phone over HTTPS, grant the permission it asks for, watch the sensor become a thing you can see, hear, or play with.

There are 23 demonstrations. An example is a Guitar Tuner.

Dmitry Grinberg posts about the Fisher Price Pixter and the first ever complete reverse engineering, documentation, emulation, and preservation of all Fisher-Price/Mattel Pixter device series and [almost] all the games.

Fisher-Price (owned by Mattel) produced some toys in the early 2000 under the Pixter brand. They were touchscreen-based drawing toys, with cartridge-based extra games one could plug in. Pixter devices of the first three generations (“classic”, “plus”, and “2.0”) featured 80×80 black-and-white screens, which makes them of no interest for rePalm. The last two generations of Pixter (“color” and “multimedia”) featured 160×160 color displays. Now, this was more like it!

Pixter was quite popular, as far as kids’ toys go, in USA in the early 2000s.

See the well documented reverse engineering details in the post here.

And see the previous blog post about porting PalmOS to the Pixter here.

J. B. Crawford posts on the Computers Are Bad newsletter about Very Low Frequency and Extremely Low Frequency transmitters as used by the US, mainly for submarine communications.

Radio communications with the US Navy dates back to 1887. And use on submarines started with launching new vehicles in 1909. Early tests didn’t go well.

It wasn’t until 1917 when two different approaches were found by different teams.

Willoughby had been experimenting with unusually low radio frequencies, below 30kHz where wavelengths become too long for most antenna designs and coils become the best receivers. These lower frequencies were significantly less affected by water than higher, more conventional frequencies, and Willoughby and Lowell built a successful prototype for what they called “long-wave” radio between two coils.

World War I led to development of Very Low Frequency (VLF) transmitters.

To maximize transmission underwater, the US Navy also experimented with Extremely Low Frequency (ELF) transmission and reception.

Balancing the desire for the lowest possible frequency against the practical challenges of ELF, the Navy settled on the range of 72-80 Hz as the most promising window for submerged submarines.

See the well written history of this technology in the newsletter here.
