Hackaday Links: May 17, 2026

May 17, 2026 by 3 Comments

To start things off, we’d like to extend a special thanks to everyone who joined us for Hackaday Europe this weekend in Lecco, Italy. It was 48 hours of fascinating talks, incredible badge hacks, and some of the greatest company you could hope for. For those who couldn’t make it in person, we didn’t forget you — expect to hear more about what went down once we get a chance to catch our collective breath.

That’s not the only thing to keep an eye out for in the coming days. This is your reminder that Amazon will be officially ending support for older Kindles in a few days. After May 20th, any of the megacorp’s e-readers that were introduced before 2012 will be persona non grata, so you should plan accordingly.

The biggest change is that these older devices won’t be able to buy digital books from Amazon, but you can still use them offline, and the fantastic Calibre makes it a breeze to load up content from other sources. To be perfectly honest, we’d advise any Kindle user to decouple their device from the Amazon mothership by using Calibre or even jailbreaking it and installing KOReader, so the end of official support is fine by us. In fact, if a surge of unsupported Kindles brings more attention and users to those projects, that suits us just fine.

Hackaday Links: April 19, 2026

We’ll start things off this week with a story that’s developing more than 25 billion kilometers from Earth — on Friday, NASA announced that the command had been sent to shut down Voyager 1’s Low-energy Charged Particles (LECP) instrument. As the power produced by the spacecraft’s aging radioisotope thermoelectric generator (RTG) continues to dwindle, engineers at the Jet Propulsion Laboratory have been systematically turning off various systems to extend the mission for as long as possible. It’s believed that deactivating LECP should buy them another year, during which engineers hope to implement a more ambitious power-saving routine. If this sounds a bit familiar, you’re probably thinking of Voyager 2. The plug was pulled on its LECP instrument back in March of 2025.

The JPL engineers hope that their new plan may allow them to reactivate previously disabled systems on the twin space probes, but even if everything goes according to plan, there’s no fighting the inevitable. At some point, there simply won’t be enough juice in the RTGs to keep the lights on. Although it’s going to be a sad day when we have to bring you that news, surviving a half-century in space is one hell of a run.

Speaking of ending a run, just a week after Amazon announced that pre-2012 Kindles would no longer be supported, the company is letting users know that the Kindle software for PCs will be discontinued in June. In its current form, at least. As Good e-Reader reports, Amazon is developing a new client for users who want to access the Kindle ecosystem from their computers, but it will only run on Windows 11. Since older software could be used to strip DRM from purchased ebooks, it seems likely this is another attempt to lock the platform down.

Reverse-Engineering An Amazon Blink Gen 3 Camera

April 13, 2026 by 12 Comments

After some water intrusion apparently killed one of [electronupdate]’s Amazon Blink Gen 3 cameras he took this opportunity to do a full teardown and analysis of all the major components. Spread across its three PCBs there are no fewer than two wireless ICs and a custom ASIC for all the major processing. There’s also a blog post with easy-to-ogle pictures.

The most basic PCB is effectively just a PCB antenna for the Silicon Labs EZR32 IC on the main PCB, using which the ~915 MHz connection with the central hub is maintained. The other smaller PCB is a bit surprising in that it contains a Cypress CYW43438 W-Fi b/g/n and BT 5.1 chip. This would seem to be used for the setup process, but considering that it also uses a central hub it is a bit of a mystery as to what it is used for exactly.

Finally, the main PCB contains all the major parts, with the custom Amazon Immedia ASIC that’s an integral part of this very low-power camera. Given that two AA cells being enough to run the camera for about two years, using off-the-shelf parts probably wasn’t good enough without some serious customization.

As for why this outdoors-rated camera failed after a few years in the outdoors, the reason appears to be water intrusion via the speaker opening. As for why a camera needs a speaker and not just the microphone is left as an exercise to the reader, but maybe it could be useful for yelling at the local kids to get off your darn lawn?

At this point, we’ll assume you already know that four humans took a sightseeing trip around the Moon and made their triumphant return to Earth on Friday. Even if you somehow avoided hearing about it through mainstream channels, we kept a running account of the mission’s highlights stuck to the front page of the site for the ten days that the crew was in space.

On the assumption that you might be a bit burned out with space news at this point, we won’t bring up it up in this post… other than to point out that excitement for the lunar flyby has driven the number of simultaneous players of Kerbal Space Program to its highest count ever — nearly 20,000 armchair astronauts spent this weekend trying to cobble together their own rocket in honor of the Artemis II mission.

With so many folks focused on the Moon it would be the perfect time for a company to sneak out some bad news, which is perhaps why Amazon picked this week to announce they would be dropping support for Kindles released before 2012. Presumably there aren’t too many first and second generation Kindles still out there in the wild, but the 2012 cutoff does mean the first iteration of the Paperwhite will be one of the devices being put out to pasture come May 20th.

On Friday, Reuters reported that Amazon is going to try to get into the smartphone game…again. The Fire Phone was perhaps Amazon’s biggest commercial misstep, and was only on the market for about a year before it was discontinued in the summer of 2015. But now industry sources are saying that a new phone code-named “Transformer” is in the works from the e-commerce giant.

At this point, there’s no word on how much the phone would cost or when it would hit the market. The only information Reuters was able to squeeze out of their contacts was that the device would feature AI heavily. Real shocker there — anyone with an Echo device in their kitchen could tell you that Amazon is desperate to get you talking to their gadgets, presumably so they can convince you to buy something. While a smartphone with even more AI features we didn’t ask for certainly won’t be on our Wish List, if history is any indicator, we might be able to pick these things up cheap on the second-hand market.

On the subject of AI screwing everything up, earlier this week, the Electronic Frontier Foundation reported that The New York Times had started blocking the Internet Archive’s crawlers, citing concerns over their content being scraped up by bots for training data. The EFF likens this to a newspaper asking libraries to stop storing copies of their old editions, and warns that in an era where most people get their news via the Internet, not having an archived copy of sites like The Times will put holes in the digital record. They also point out that mirroring web pages for the purposes of making them more easily searchable is a widely accepted practice (ask Google) and has been legally recognized as fair use in court.

Assuming we take the NYT’s side of the story at face value, there’s a tiny part of our cold robotic heart that feels some sympathy for them. Over the last year or so, we’ve noticed some suspicious activity that we believe to be bots siphoning up content from the blog and Hackaday.io, and it’s resulted in a few technical headaches for us. On the other hand, what’s Hackaday here for if not to share information? Surely the same could be said for any newspaper, be it the local rag or The New York Times. If a chatbot learning some new phrases from us is the cost of doing business in 2026, so be it. Can’t stop the signal.

Auto-Download Your Kindle Books Before February 26th Deadline

February 18, 2025 by 86 Comments

With the news that Amazon will no longer be allowing users to download their Kindle books after February 26th, many are scrambling to download their books before it’s too late. The most up-to-date project for automating this process appears to be Amazon Kindle Bulk Downloader.

As the company that famously removed 1984 from thousands of devices without users permission, this is a move that shouldn’t be surprising, but is still disappointing, especially for those of us that were somewhat early adopters of ebooks with Kindles that don’t have a WiFi connection. (Yes, you can tell us about how you bought a Sony reader before the Kindle even came out in the comments.)

The Typescript-coded tool runs inside bun which can be installed in any of the big three OSes and even has a handy Docker image if that’s more your speed. Whether you use this tool or not, if you have any Kindle books we’d implore you to download them now.

Once you’ve downloaded those books, how about cracking the DRM either with LEGO or with software like Calibre. You could load it on a completely Open Source Reader then.

Disappointing news this week for those longing for same-hour Amazon delivery as the retail giant tapped the brakes on its Prime Air drone deliveries. The pause is partially blamed on a December incident at the company’s Pendleton, Oregon test facility, where two MK30 delivery drones collided in midair during light rain conditions. A Bloomberg report states that the crash, which resulted in one of the drones catching fire on the ground, was due to a software error related to the weather. As a result, they decided to ground their entire fleet, which provides 60-minute delivery to test markets in Arizona and Texas, until a software update can be issued.
