Spotify has lost all enthusiasm for the little music devices it sold for just half a year. Firmware hackers, as usually happens, have a lot more interest and have stepped in to save, and upgrade, a potentially useful gadget.
Spotify’s idea a couple years ago was a car-focused device for those who lacked Apple CarPlay, Android Auto, or built-in Spotify support in their vehicles, or just wanted a dedicated Spotify screen. The Car Thing was a $100 doodad with a 4-inch touchscreen and knob that attached to the dashboard (or into a CD slot drive). All it could do was play Spotify, and only if you were a paying member, but that could be an upgrade for owners of older cars, or people who wanted a little desktop music controller.
But less than half a year after it fully released its first hardware device, Spotify gave up on the Car Thing due to “several factors, including product demand and supply chain issues.” A Spotify rep told Ars that the Car Thing was meant “to learn more about how people listen in the car,” and now it was “time to say goodbye to the devices entirely.” Spotify indicated it would offer refunds, though not guaranteed, and moved forward with plans to brick the device in December 2024.
It was always open source, just not publicly
Enter Dammit Jeff, a YouTuber who dove into his device and shows off some alternative software ideas for it (as we first saw on Adafruit’s blog). He even likes the little thing, noting that its wheel feels great, and that the four buttons on the top—originally meant for favorite playlists—present a lot of possibilities.
Disposable vapes are indefensible. Many, or maybe most, of them contain rechargeable lithium-ion batteries, but manufacturers prefer to sell new ones. More than 260 million vape batteries are estimated to enter the trash stream every year in the UK alone. Vapers and vape makers are simply leaving an e-waste epidemic to the planet’s future residents to sort out.
To make a point about how wasteful this practice is—and to also make a pretty rad project and video—Chris Doel took 130 disposable vape batteries (the bigger “3,500 puff” types with model 20400 cells) found littered at a music festival and converted them into a 48-volt, 1,500-watt e-bike battery, one that powered an e-bike with almost no pedaling more than 20 miles. You can see the whole build and watch Doel zoom along trails on his YouTube video.

To be clear: Do not do this. Do not put disposable vape cartridges in a vise clamp to “pop out” their components. Do not desolder them from vape cartridges that have a surprising amount of concentration still in them. Do not wire them together using a balance board, group them using 3D-printed cell holders, and then wire them in series. Heck, do not put that much power into a rear hub on a standard bike frame, at least more than once. Doel has a fire extinguisher present and visible on his workbench, and he shows you what happens when two of the wrong batteries happen to make momentary contact—smoke, coughing, and strong warnings.
And yet, when you see Doel get 33 kilometers (about 20.5 miles) on his vape-powered ride, almost entirely without pedaling, hitting 32 miles per hour once, the point is made. We are tossing out a lot of battery materials that could be doing a lot of other things. Doel estimates his “dodgy bike” cost about $60 in filament and materials to piece together. Most of the cells are rated for a minimum of 300 cycles, which is both not a lot, but also more than some bikes and scooters actually take on.

Georg Lukas
Back in 2010—after the first iPhone, but before its camera was any good—a mirrorless, lens-swapping camera that could upload photos immediately to social media or photo storage sites was a novel proposition. That’s what Samsung’s NX cameras promised.
Unsurprisingly, Samsung didn’t keep that promise too much longer after it dropped its camera business and sales numbers disappeared. It tried out the quirky idea of jamming together Android phones and NX cameras in 2013, providing a more direct means of sending shots and clips to Instagram or YouTube. But it shut down its Social Network Services (SNS) entirely in 2021, leaving NX owners with the choices of manually transferring their photos or ditching their cameras (presuming they had not already moved on).
Some people, wonderfully, refuse to give up. People like Georg Lukas, who reverse-engineered Samsung’s SNS API to bring back a version of direct picture posting to Wi-Fi-enabled NX models, and even expand it. It was not easy, but at least the hardware is cheap. By reflashing the surprisingly capable board on a USB 4G dongle, Lukas is able to create a Wi-Fi hotspot with LTE uplink and run his modified version of Samsung’s (woefully insecure) service natively on the stick.
What is involved should you have such a camera? Here’s the shorter version of Lukas’ impressive redux:
Installing Debian on the LTE dongle’s board
Creating a Wi-Fi hotspot on the stick using NetworkManager
Configuring the web server now running on that dongle
The details of how Lukas reverse-engineered the firmware from a Samsung WB850F are posted on his blog. It is one of those Internet blog posts in which somebody describes something incredibly arcane, requiring a dozen kinds of knowledge backed by experience, with the casualness with which one might explain how to plant seeds in soil.
The hardest part of the whole experiment might be obtaining the 4G LTE stick itself. The Hackaday blog has detailed this stick (and also tipped us to this camera rebirth project), which is a purpose-built device that can be turned into a single-board computer again, on the level of a Pi Zero W2, should you apply a new bootloader and stick Linux on it. You can find it on Alibaba for very cheap—or seemingly find it, because some versions of what looks like the same stick come with a far more limited CPU. You’re looking for a stick with the MSM8916 inside, sometimes listed as a “QualComm 8916.”
Lukas’ new version posts images to Mastodon, as demonstrated in his proof of life post. It could likely be extended to more of today’s social or backup services, should he or anybody else have the time and deep love for what are not kinda cruddy cameras. Here’s hoping today’s connected devices have similarly dedicated hackers in the future.

There is the mental image that most people have of electronics recycling, and then there is the reality, which is shredding.
Less than 20 percent of e-waste even makes it to recycling. That which does is, if not acquired through IT asset disposition (ITAD) or spotted by a worker who sees some value, heads into the shredder for raw metals extraction. If you’ve ever toured an electronics recycling facility, you can see for yourself how much of your stuff eventually gets chewed into little bits, whether due to design, to unprofitable reuse markets, or sheer volume concerns.
Traditional hard drives have some valuable things inside them—case, cover, circuit boards, drive assemblies, actuators, and rare-earth magnets—but only if they avoid the gnashing teeth. That’s where the DiskMantler comes in. Garner Products, a data elimination firm, has a machine that it claims can process 500 hard drives (the HDD kind) per day in a way that leaves a drive separated into those useful components. And the DiskMantler does this by shaking the thing to death (video).

The DiskMantler, using “shock, harmonics, and vibration,” vibrates most drives into pieces in between 8–90 seconds, depending on how much separation you want. Welded helium drives take about two minutes. The basic science for how this works came from Gerhard Junker, the perfectly named German scientist who fully explored the power of vibrations, or “shear loading perpendicular to the fastener axis,” to loosen screws and other fasteners.
As Garner’s chief global development officer, Michael Harstrick, told E-Scrap News, the device came about when a client needed a way to extract circuit boards from drives fastened with proprietary screw heads. Prying or other destruction would have been too disruptive and potentially damaging. After testing different power levels and durations, Garner arrived at a harmonic vibration device that can take apart pretty much any drive, even those with more welding than screws. “They still come apart,” Harstrick told E-Scrap News. “It just takes a little bit.”
Improving the recovery and sorting ease of hard drives is itself a useful thing, but the potential for rare-earth magnet recycling is particularly attractive. Most rare-earth magnet recycling involves “long-loop” recycling, or breaking them down into rare earth elements and then putting those back into the magnet production stream, which is energy-intensive and not very cost-effective. Electric vehicles and wind turbines have huge amounts of rare-earth magnets in them but rarely see recycling. Hard drives, while individually small, are massive in scale, with roughly 259 million shipped in 2021.
One Canadian firm, based on a University of Birmingham-patented process, wants to reuse drive magnets more directly, creating new sources that don’t require extraction and aren’t quite so globally concentrated. That Canadian firm, HyProMag, uses robotics to find and extract drives’ permanent magnets, then sends the rest of the disk off for recycling.
The technology is not all there yet, but soon enough, it looks like something interesting will shake out.

Fairphone
Fairphone has spent years showing us that it could do what major phone manufacturers suggest is impossible: make a modern-looking phone, make it brazenly easy to open up, design it so battery swaps are something you could do on lunch break, and also provide software support for an unbelievable eight to 10 years.
Bluetooth headphones, specifically wireless earbuds, seemed destined to never receive this kind of eco-friendly, ownership-oriented upgrade, in large part because of how small they are. But the Fairbuds have arrived, and Fairphone has made them in its phones’ image. They’re only available in the EU at the moment, for 149 euro (or roughly $160 USD). Like the Fairphone 4, there’s a chance interest could bring them to the US.
The highlights include:
Seven replaceable parts from the buds and charging case, all sold by Fairphone
A two-year warranty, expanded to three if you register them
Batteries in both the case and buds that are replaceable
IP54 sweat and water resistance
Individual left or right buds and a charging case that Fairphone will sell to you
Made with “fair and recycled materials,” in “fair factories,” and “climate conscious and electronic waste neutral,” (as explained by Fairphone).
Of course, the buds also, you know, produce sound, with 11 mm titanium drivers. The Fairbuds sport active noise-canceling and ambient sound modes, Bluetooth 5.3 with “dual point connectivity” for quick-switching between devices, and a Fairbuds app for customizing EQ and preset settings. The buds’ 45 mAh batteries carry about six hours of listening per charge, and their 500 mAh case adds another 20 hours.

It’s not Fairphone’s first foray into fair, repairable sound devices. The firm previously made the since-discontinued True Wireless Stereo Earbuds and still offers Fairbuds XL, which are not buds at all but full over-ear headphones (and also EU-only).
The best that major-brand earbuds have ever done in repairability is “maybe you can do it, if you’re careful, and you don’t mind losing water resistance.” Taylor Dixon took apart six buds for iFixit back in 2020, and only Sony’s WF-1000XM3 didn’t require soldering, cutting and re-applying glue, and a steady hand working in very small spaces.
AirPods? AirPods are something else. One firm, The Swap Club, has figured out some means of getting the battery out of AirPods and selling them refurbished. But they only accept regular AirPods, not AirPods Pro. Alternatively, Apple will send you a pre-paid label to send in your spent AirPods for recycling, though with no trade-in credit. Even if Apple gets some kind of material out of the AirPods, a lot of them (and nearly every other wireless earbud) end up as waste after 18 months or however long their batteries last.
Fairbuds may or may not take a big chunk out of the market for AirPods, Beats, Pixel Buds, or other use-and-toss airbuds. But at a minimum, they give people something to point to as proof this category could be a lot better.
