Team Repair Breaks Things To Teach People How To Fix Them

July 25, 2026 by 20 Comments

Would you buy a broken device, fix it, then return the repaired item? [Team Repair] hopes you will.

Many people would rather repair what they have than have to get a new device and deal with all the annoyances of shopping and getting used to a new item. The problem is, most people don’t have any experience fixing their broken electronics and are intimidated by the process. [Team Repair] has found that helping people through the process the first time is a big confidence boost, especially when they have a test piece to work with.

[Team Repair] started with workshops and now has a “Fixers Club” subscription box for 8-14 year olds where they will send a broken device every three months to fix. After the device is repaired, it gets sent back into Team Repair, or iFixit in the US, to be broken again and sent to the next fixer. For grownups, there is a similar smartphone repair kit, but it’s currently waitlisted. If you’re in the UK, they even have a classroom program if you want to recruit larger groups into your fixer corps.

Curious about other ways to get into repairing your own things? We don’t recommend starting with smart rings, but learning analog repairs like zippers or turning a laptop into a desktop could be good places to start?

Benchmarking Repairability Scores With An Asus Tablet

July 14, 2026 by 13 Comments

A few years ago, France introduced a mandatory repairability score for consumer goods like laptops and tablets. It involves five criteria that range from documentation and availability of spare parts to ease of disassembly, with the manufacturer using a government-provided checklist to determine their score.

Recently Asus determined that their Asus ROG Flow Z13 – model GZ302EA – scored a 10 out of 10 using this system. This led [iFixit] to run the same tablet/laptop hybrid through their own rating system.

You can find the filled-out spreadsheet for this device here, with this Asus-provided site showing a list of devices that all score a 10/10 or a measly 9.9/10 according to this system. As a self-reported score it is hard to take it as the objective truth, as there is every incentive for the manufacturer to tweak the truth to their own benefit and gloss over inconveniences. This is where it’s interesting to compare it with [iFixit]’s 7/10 score.

On documentation, Asus gives itself a perfect score but [iFixit] finds it to be incomplete. Removal of one fan requires the disassembly of the cooler with its liquid metal thermal interface on the CPU. The wireless card, and most ports, are soldered to the mainboard. On the bright side, after you get the screen off, the insides are quite modular, which is a plus.

[iFixit] dings three points: for documentation, soldered-down components, and a fan accessibility glitch. Parts accessibility outside of France is also significantly harder, but one can hardly blame the French system for that. Overall the French self-reported rating would seem to be a fair start, but depending on which criteria you define as required you may find yourself disagreeing with the score.

In the case of LPDDR5 RAM one could argue for example that with LPCAMM2 modules soldering RAM onto the mainboard ought to be a thing of the past, and Wi-Fi modules should always be removable as well. You can take that up with the French regulators.

Hacking Amazon Echo Show 8 3rd Gen Via UART And EMMC

July 8, 2026 by 8 Comments

Even with Amazon’s Echo Show devices running Linux in the form of the Android-derived FireOS, using them for non-Amazon approved purposes can be a chore at best. In the case of the Echo Show 8 even simple workarounds using ADB and the bootloader have been locked-down, requiring more drastic measures. Here [Vowed] over at the XDA forums shows off one such hack, involving directly tapping into the device’s eMMC.

Suffice it to say that this is not a hack for the faint of heart, with even the iFixit teardown guide for this device being rather daunting. Even after you get access to the mainboard, you still have to remove or cut open the metal can that covers the eMMC, so that you can unleash an eMMC programmer on it. It’s best to make sure to make a backup image of the original contents too, just in case you have to restore things.

With the shield out of the way you can solder fine wires to pads that connect to the eMMC to program it. You also have to solder wires to pads for the UART, though if you’re fancy you can also create a custom pogo pin adapter. With a serial connection established to the original firmware you can then enable features like ADB, and courtesy of the connected eMMC adapter it’s possible to directly alter system files to make rooting as easy as possible.

In addition to rooting the system you can also do a straight replacement of the eMMC contents, such as the demonstrated Debian installation. Even if not the most easy of mods, it’s good to see that it’s possible to repurpose these devices.

Linux Fu: Upcycling An Old Router

June 23, 2026 by 28 Comments

You’re wandering through a thrift store and spot an old router for ten bucks. Worthless, right? But in this case, it was a Google OnHub, which, at the time, was pretty premium and still isn’t anything to sneeze at. Of course, Google abandoned it long ago, and it runs Chrome, so pass, right? Of course I didn’t. In fact, I bought two for less than $20. The question is always the same: what do you do with it?

OpenWrt will run on the device. That’s a good start, but merely replacing the firmware isn’t much of a project. The more interesting question is whether the hardware can still do something useful. I had a specific need: connect a wired workstation to a reasonably distant WiFi network without running cable and without suffering the usual double-NAT headaches that come from turning the router into yet another subnet. For this, the OnHub turned out to be nearly perfect.

The Hardware

The OnHub was Google’s first Wi-Fi router, built by TP-Link and ASUS in different versions. Mine was the TP-Link model, and one was missing a bit of plastic cowl trim. Under the hood, it has a Qualcomm IPQ8064 dual-core processor — a dual-core ARMv7 — multiple radios, gigabit Ethernet, and enough memory to run OpenWrt comfortably: 1 GB of RAM and 4 GB of flash. The processor also has two network offload processors, but it isn’t clear to me that the stock OpenWrt build uses them.

These devices were expensive when new, but now show up regularly at thrift stores and surplus sales. Installing OpenWrt was straightforward. You do need to remove a screw that covers the magic switch at the bottom, but that’s not a big problem. You can just peel the rubber foot back if you don’t want to remove it. However, the interesting part came afterward.

The Repair Nightmare That Are Smart Rings

June 20, 2026 by 21 Comments

In the quest to make every wearable device ‘smart’, a lot of electronics along have to be crammed in very small spaces, along with ways to make them resistant to environments that our bodies do not mind, like getting hit by a rainstorm or simply washing our hands. These two factors combined make especially devices like smart rings an interesting case study for repairability, with [iFixit] recently taking apart a modern Oura smart ring to assess its e-waste factor after the built-in battery dies.

The subject of the teardown video is the Oura Ring 5, a $400 smart ring that’s designed to track your vitals much like a wrist-worn fitness tracker — just in a much smaller package. This metal-and-epoxy sandwich can definitely survive a good rain shower and washing of hands, but to get to the internals rather forceful methods were needed, unlike previous Oura and Samsung smart rings where some applied heat was enough.

In the Ring 5’s case even more heat was needed to make the inner ring start to slide out, but by that point the Li-ion battery inside had already popped from the heat. The inner ring then got stuck and more violence was required to continue the disassembly and get to the super-tiny, 10.5 mAh battery. Of course, at this point the smart ring really won’t be getting back together, never mind still work or be waterproof, which is a central issue with these smart rings.

With the EU’s February 2027 deadline for user-replaceable batteries looming on the horizon, it’ll be interesting to see whether devices like this can squeeze into an exception category, or whether manufacturers will have to massively redesign or stop selling these devices to this rather large market. So far this particular regulation has already forced Nintendo to make a special Switch 2 console for the EU.

Hackaday Links: June 7, 2026

June 7, 2026 by 8 Comments

Christopher Nolan’s The Odyssey isn’t hitting theaters for another month or so, but if you’re already planning your trip to the cineplex, you may want to check out this page on the movie’s website which lets you view the trailer in the six (!) different formats it’s being released in.

We don’t really have an opinion on the big-screen adaptation of the epic tale as a piece of media, but from a technical standpoint, it’s interesting to see how the viewing experience changes between the 70mm IMAX version with an aspect ratio of 1.43:1 and the 35mm cut at 2.39:1. Unfortunately, the website offers no way to approximate what the movie will look like once compressed, streamed over the Internet, and displayed on a cheap TCL TV, to say nothing of how the viewing experience will be impacted should you watch the movie on your phone by way of a series of short YouTube clips while going to the bathroom. Maybe Nolan is saving that for his next film.

If you head over to the movies in one of Waymo’s vehicles, you can feel a little better about the long-term ecological impact of your trip thanks to a recently announced partnership between the autonomous car maker and B2U Storage Solutions. Under the agreement, old batteries pulled from Waymo’s fleet of self-driving electric cars will get a second life as localized grid storage.

The idea is that batteries which no longer hold enough charge to power a robo-taxi should still have enough capacity to store the energy produced by renewable sources so it can be doled out later when the demand goes up. By installing these batteries in the cities that Waymo actually operates their vehicles in, they don’t have to worry about shipping them around either — they can just yank them out of the car, and wire them right into the grid. Of course, eventually the batteries will be too cooked to adequately perform in this role as well, but this should give them a few more productive years before they get torn down and scrapped.

2026 Hackaday Europe: Pre-party, More Workshops, And Everything Else

May 12, 2026 by 10 Comments

With Hackaday Europe no more than two days away, we want to help you wrap up all of the last loose ends. And that means last-minute changes in the workshop schedule, details on the Friday night pre-party, and more! Some tickets for the event itself, the workshops, and the pre-party (reservations required) are still available right here.

Pre-Party, Friday May 15th

Kick off the weekend with us at the official Hackaday Europe pre-party at Soqquadro Restaurant, Piazza Era 7, 23900 Lecco, Italy. Enjoy the Italian aperitivi on the gorgeous Lago di Lecco waterfront. Your ticket includes two drinks and an array of delicious snacks. It’s the Italian way to pregame the weekend ahead. Bring a hack, or just relax and hang out. Your choice. Either way, make sure you pre-register. (On the preregistration page, scroll all the way down past the workshops.)

Workshops

Unfortunately, the Let’s Mesh workshop has been canceled, but the good news, thanks to our incredible sponsors, we’ve added two great new workshops to the lineup. On Saturday, May 16th, we’ll have Tiny Tapeout, When Code Needs a Body, and Fault Injection 101. Sunday features EchoGlow: Arduino UNO Q Workshop with the brand-new Arduino Q devices, from 11:00 AM – 2:00 PM.

Tickets and full descriptions are available at registration.

Lightning Talks

On Sunday afternoon, we’ll dedicate some time to Lightning Talks. These are short, seven-minute talks, with or without slides, on whatever interests you at the moment. If you’ve got hacks or deep thoughts to share with us, you’ll never find a more receptive audience. Register now! Talk slots are FIFO.

Thanks, and See You Soon!

If you’ve never attended a Hackaday event before, we’re excited to see you. Half the fun is the crowd that convenes. If you want to bring along a hack to informally show-and-tell, it’s a great icebreaker. You won’t have to bring food or drinks – we’ve got that covered all weekend.

If you’re an old Hackaday hand, we’re stoked to see you again! A first at Hackaday Europe is going to be whatever large fraction of our SAO collection fits into carry-on luggage, and a sweet-looking SAO wall made by Hackaday Superfriend [Thomas Flummer]. If you have an SAO that you’d like to add to our pile, bring it along! It’s about time for us to do a photo gallery and write-up of everything we’ve got.

And we can’t leave without thanking our broad array of sponsors who make Hackaday Europe possible:
