Hackaday Links: July 12, 2026

Although we’d rather bring you news of clever modifications and repairs down on the farm, more often than not, the name “John Deere” has appeared on the pages of Hackaday because of their opposition to farmers actually being able to work on the machines their livelihoods depend on. But thanks to a settlement reached between the company and the Federal Trade Commission this week, farmers seem to have been handed a much-needed win in the Right to Repair battle.

When a lawsuit against a company ends in a settlement, it usually means spending money they would rather pay than go to court. Indeed, earlier cases against John Deere have resulted in plenty of checks being written. But this time around, the FTC agreement requires Deere to make its diagnostic and repair software available to owners and independent shops. It also has a clause that prevents them from retaliating against owners who want to handle their own repairs rather than going through the company’s official service channels — hard to believe that’s something that actually needs to be specified, but it does give you a hint as to just how bad the situation has been. We’ll definitely be keeping an eye on this story.

Sounds like the Feds were busy this week, as the Federal Communications Commission also gave the green light to Reflect Orbital to launch a prototype satellite for their controversial “sunlight as a service” concept. The company plans to put the spacecraft into a roughly 600 km orbit around the planet, where it will deploy its 324-square-meter reflector and angle itself to illuminate a spot on the ground. It might sound like something a Bond villain would come up with, but Reflect Orbital says the capability will be used to beam sunlight directly onto solar panels at night and to provide light for search-and-rescue operations.

As you might expect, providing such a service on a global scale would require many such reflectors, which is where the concern really comes in. Critics note that a sky full of literal mirrors can cause all sorts of issues, ranging from the scientific to the scenic. The American Astronomical Society points out that each satellite in the constellation could appear to be four times as bright as the full Moon, and that it’s possible an amateur sky watcher could get an eyeball full of redirected sunlight should one of them unexpectedly zip past the aperture of their backyard telescope.

Get A Handle On This Compact Pi Portable

July 9, 2026 by Tom Nardi 20 Comments

Between the speed and reliability of modern desktop 3D printers and the abundance of powerful single-board computers, there’s never been a better time to build a personal computing device that bucks traditional forms for something more bespoke. Whether you want to go all in on Gibsonian cyberdeck aesthetic or a distraction-free writing device to take notes on, there’s no shortage of examples out there that you can turn to for inspiration.

A recent entry into the field, the Don’t Panic Cyberdeck from [Paul Rickards], is a particularly approachable specimen for those looking to experiment with alternative computing experiences. While the final product certainly stands out among the throngs of nearly identical laptops, it doesn’t take a huge investment in time or money to put one of your own together.

Which is not to say the project is simplistic, exactly. Rather, as [Paul] released the design under the Creative Commons license and was kind enough to provide not only a detailed Bill of Materials but assembly instructions, the community is able to benefit from the sleepless nights he no doubt put into it.

In it’s baseline configuration, the Don’t Panic uses a Raspberry Pi 3A+, a Pimoroni HyperPixel 4.0 Square LCD (touch optional), and a Rii 518BT keyboard. Those core components would be enough to get you up and running, but if you want battery power you’ll also need to add a LX-2BUPS UPS board and a pair of 18650 cells. Audio might be nice as well, and for that [Paul] recommends a PAM8403 breakout board. He’s even got a printable volume knob that slips over the board’s potentiometer and peeks outside the case.

Of course, the best cyberdeck builds are customized to meet their owner’s specific needs, so your loadout doesn’t need to match [Paul]’s exactly. Except the handle, anyway. That feature is non-negotiable. Mainstream computers have far too few handles for our liking.

This DIY Time Server Is More Accurate Than You Need

July 8, 2026 by Tom Nardi 25 Comments

You almost certainly don’t have an application for the sort of accurate timekeeping that’s made possible by this enhanced version of [Cristiano Monteiro]’s satellite-backed time server. By his own admission, the vast majority of users will be more than happy to have their system’s time synchronized by the traditional Network Time Protocol (NTP). But if you’re really chasing those last few microseconds, that’s where the Precision Time Protocol (PTP) comes in.

With NTP, you can get within 10 milliseconds or so of your upstream time source — but PTP is accurate down to nanoseconds. Unless you’re performing some kind of scientific research, running a robotic assembly line, or perhaps doing high-speed financial trading, there’s no reason for this level of accuracy. In fact, PTP is such a niche technology that until the release of the ESP32-P4, [Cristiano] couldn’t even find an affordable enough chip that supported it.

Hardware-level support for PTP is important as there’s no way to achieve this level of accuracy with software alone, the capability needs to be baked into the Ethernet controller. As you might expect, it takes a highly accurate time source to make the most of PTP, and that’s where the navigation-grade Global Navigation Satellite System (GNSS) receiver comes in. All told the cost of the build is unsurprisingly higher than that of its predecessor, but [Cristiano] says it’s still a couple zeros shy of what a commercial offering would run.

As with his original time server from 2021, [Cristiano] made sure this build was as friendly as possible for hackers and makers. We especially like the 3D printed case designed in OpenSCAD, and his insistence that the gadget have a front panel with blinking status LEDs. Again, the vast majority of us don’t need our clocks to be accurate down to the nanosecond…but it’s nice to know we have the option.

ESP32 Keeps Tabs On Your Local Airspace

July 8, 2026 by Tom Nardi 22 Comments

We know, we know. Despite being called ESP32-Plane-Radar, this project from [Mateusz Juszczyk] isn’t actually using radar. But thanks to the round LCD this desktop gadget does a fantastic job of recreating a classic radar display, and by pulling in Automatic Dependent Surveillance–Broadcast (ADS-B) data, the visuals even match nearby real-world aircraft.

Perhaps the best part of this project is just how easy it is for others to get in on the action. Although the presentation certainly looks professional — and expensive, if we’re being honest — there’s nothing particularly exotic going on here. Specifically, there’s ESP32-C3 Super Mini behind the scenes cranking through the ADS-B data and pushing it out to a circular GC9A01 display. A minimalistic 3D printed enclosure holds both components, and while it’s undeniably slick as-is, we can’t help but think there’s potential here for more elaborate designs.

As you probably guessed from the lack of a radio in the parts list, the code [Mateusz] provides doesn’t actually sniff ADS-B out of the air. It connects to the local network over WiFi, and then hits adsb.fi to pull in crowdsourced flight data. Since the device has to connect to the network anyway, the code also offers up a web-based configuration interface which puts a little more polish on what’s already an impressive presentation.

We used a round GC9A01 display on the Vectorscope back in 2023, so if anyone ports this over to their old Supercon badge we’d love to see it in action.

Thanks to [Mauricio] for the tip.

It’s Now Imperative That You Copy That Floppy

July 7, 2026 by Tom Nardi 21 Comments

In the early 1990s, Don’t Copy That Floppy was an anti-piracy campaign that attempted to connect with computer-savvy youth through the power of hip-hop. While somewhat difficult to imagine given our current draconian Digital Rights Management (DRM) hellscape, warning kids about the potential legal ramifications of duplicating floppy disks containing copyrighted software was seen as necessary since at the time there was usually nothing preventing users from simply copying the contents of one disk to another.

Unfortunately 30+ years down the road, we’re now finding that somebody really should have been backing up some of those disks. Which is why the University of Cambridge of launched the Future Nostalgia project and produced Copy That Floppy! — a phenomenal guide on preserving the contents of floppy disks while we still can.

Visualizing a disk’s flux stream can identify debris and damage.

There’s no telling how much data could potentially be lost to time because its stuck on such an antiquated and fragile storage media, and the situation only gets worse with the passage of time. The problem isn’t just that modern computers don’t have floppy drives. The disks themselves degrade with age, a process which is accelerated if they aren’t stored properly.

As such, Copy That Floppy! only briefly touches on the most ideal situation — that is, buying a USB floppy drive and making copies of the bog standard 3.5 inch disks you might come across. It then moves right on into more advanced topics, such as interfacing with less common drive types, how to safely clean floppies, and the use of advanced tools such as Greaseweazle to analyze captured disk images.

We’ve seen demonstrations of some of these techniques before, and a few years back Adafruit got interested in floppy preservation with modern hardware. But in-depth guides like these that pull all that information together into one place are valuable resources.

Hackaday Links: July 5, 2026

Happy belated July 4th to all the readers from the United States — hopefully you aren’t reading this from a hospital bed after losing a hand or burning off your eyebrows. While we suspect amateur firework shows and their related injuries will be around for many years to come, we did note that many major cities switched over to drone shows this year.

At least on paper, the appeal is obvious. Beyond the fact that drones are safer and quieter than pyrotechnics, they’re also capable of far more complex displays. Good luck trying to draw George Washington’s face in the sky with exploding rockets. But even if it’s a little more than nostalgia, there’s still something about the sights and sounds of fireworks that enthrall audiences. For many, the whole “rockets’ red glare” thing is a bit more meaningful than the “drones’ red LEDs.”

Earlier this week, we brought you news that Sony would stop producing physical PlayStation discs in January 2028. Many gamers are understandably concerned about the long-term implications such a move will have for software ownership, and while the negative reactions online haven’t bothered Sony enough to get them to amend their plans, they have clarified the situation with developers by explaining that games published before the cutoff date aren’t impacted. So if a developer has a hit title that drops in the summer of 2027 and they want to keep cranking out discs, additional orders can still be placed. Not much of a reprieve, but it will give the community a little more time to figure out what comes next.
