EU Adds Exemptions To User-Serviceable Batteries Rules

July 17, 2026 by 70 Comments

Built-in batteries put a timebomb inside devices, with especially the calendar aging feature of Li-ion chemistries setting a hard limit on when you’ll have to toss the device or figure out a way to replace the battery somehow. Here the EU’s Battery Regulation policy with the 2027 implementation of the user-serviceable battery requirement provided a lot of hope. Now six new categories of exemptions are diminishing what could have been a bonanza of easy repairability.

Most notable here are smartwatches, fitness trackers, wireless earbuds and other so-called ‘wet devices’, which as GSMArena also notes is an area where having a user-replaceable battery might affect features like being water-resistant. Something which is also relevant for e.g. outdoor wireless speakers. There’s also a new exemption for smartphones, where if its battery retains at least 83% of its original capacity after 500 charge cycles, battery replacement has to be only replaceable by professionals. Which is probably code for ‘glue, hotplates and prying tools’.

Considering just how daft of an idea built-in batteries are, this is somewhat disappointing to see. While it’s understandable that ‘wet devices’ get such broad exemptions, it should be noted here that advanced technologies like gaskets are neither complicated nor expensive. You can even hand the average user a tube of RTV silicone and let them go to town on a part in the happy knowledge that there’s never such a thing as ‘too much’ RTV silicone.

It is likely that there was some pressure from the industry on the EU to not change too much, but at the very least us happy few in the EU will be getting a new Nintendo Switch 2 with easily replaced battery in both the main unit and its controllers. For the average rechargeable device you keep kicking around the house this should also still apply as long as its manufacturer cannot squeeze it into one of these exemption categories.

The Right to Repair battles shall continue.

GOES-19 Goes Down, NOAA Investigating

July 16, 2026 by 17 Comments

Some breaking news from geostationary orbit, as the National Oceanic and Atmospheric Administration (NOAA) has announced that its newest Geostationary Operational Environmental Satellite (GOES) satellite unexpectedly went offline last night, and as of this morning, remains stuck in safe mode.

Launched in June of 2024, GOES-19 is one of four operational weather satellites that NOAA operates to provide forecast data and severe weather monitoring for the entire Western Hemisphere. The satellite is specifically responsible for covering the continental United States, Central and South America, as well as the Atlantic Ocean. This makes it a particularly critical asset even under normal circumstances, but the fact that it’s gone blind during the Atlantic hurricane season and while smoke from the raging Canadian wildfires is drifting over the Northeast and making the skies over Boston and New York City look like Mars is something of a worst-case scenario.

The good news is that two of the four satellites operate as orbital spares — the satellite that GOES-19 replaced in 2024, GOES-16, is still operational and can stand in as a backup for its coverage area. Obviously, it’s quite a bit older, having launched back in 2016, but it’s of the same design as GOES-19, and in good health, so there should be no degradation of service.

Still, getting GOES-19 back online will be critical for NOAA and the National Weather Service, and we expect they’ll be providing regular updates as the situation develops. Stay tuned.

Open Book Touch Makes Crowd Funding Debut

July 14, 2026 by 22 Comments

If you have even the slightest interest in open hardware e-readers, you’ve certainly heard of [Joey Castillo]’s Open Book project. We’ve covered his efforts to develop an affordable reader that delivers a Kindle-like experience without the Orwellian megacorp trappings for several years now, and watched with great interest as the core hardware has evolved.

So we were particularly excited over the weekend to see the Open Book Touch finally hit Crowd Supply, and judging by the fact that the campaign for the $149 device has already blown past 60% of its funding goal in just a few days, it seems like we weren’t the only ones.

2026 Hackaday Supercon: Call For Proposals

July 13, 2026 by 5 Comments

We are absolutely stoked to announce that the Hackaday Superconference is taking place this year November 6th through 8th in glorious Pasadena California, and we want to see you there!

If you’ve been to any of the previous nine Supercons, you know that it’s a fantastic gathering of the most motivated and interesting hackers around — but it’s also been a relatively small gathering. And while we love the very high signal-to-noise ratio of folks who show up, we’re always a little bit sad when the tickets sell out because it represents hackers who couldn’t be there.

So this year, we’re celebrating Supercon Ten by expanding out of our traditional location at the Design Lab so that we can accommodate 20% more hackers, while still keeping the cozy nature of the event intact. So if you’ve been wanting to come to Supercon, but procrastinated the ticket sales every year, this year is looking 20% better.

Porting The Nvidia GPU Driver To Haiku For 3D Acceleration

July 12, 2026 by 3 Comments

As good as a desktop OS may be, at some point it has to feature accelerated 3D graphics. This has been a bit of a sticking point for Haiku OS, as none of the big names in GPU cards are likely to start putting out drivers for this OS any time soon. Fortunately there is the Linux open source driver code from Nvidia that can be used as a jumping-off point for a port, which is what [X512] and the community over at the Haiku forums did over the course of more than a year.

In a recent video [Action Retro] takes a poke at the fruits of these efforts, trying out the driver with an RTX2070 Super GPU. Of note is that this driver requires the GSP (GPU System Processor) controller that got added by Nvidia with the Turing series of GPUs, meaning that you need at least a GTX16 or RTX20 series card.

You can get an installation package from the GitHub repository, such as for the v0.0.2 pre-release that was created in January of 2026. In this pre-release state quite a few things are working, with the ability to play 3D games at a reasonable FPS being the biggest improvement over plain VESA mode. Features like CUDA are not available as they’re not in the open sourced section, of course.

In the [Action Retro] video the whole installation process is demonstrated, starting with a fresh nightly Haiku build. First the gaming performance in software-rendered VESA mode is demonstrated before the GPU driver is installed. This shows a marked improvement in performance, although Minecraft needs to be updated for the newest Mesa library that omits OSMesa, so that couldn’t be tested. Overall it shows that Haiku has made another massive leap forward in becoming a viable daily driver OS.

Meanwhile, over on the ReactOS side of things we just saw a Half-Life 2 playthrough by [Aotori Hibiki], on an Intel Sandy Bridge PC with GeForce 8400GS graphics. Here ReactOS has the advantage of being Windows NT-compatible, including WDDM-style GPU drivers, allowing it to use the same drivers as Windows. Simultaneously, ReactOS is now implementing its first NT6 kernel API calls to make it compatible with modern  (Vista+) Windows.

The upshot here is that for people who want to daily drive an open source OS with all the creature comforts imaginable, things have never seemed more promising. Especially for people who don’t want Yet Another Linux Distro but just an utterly boring desktop-centric, single-user focused OS that Just Works™ these are great tidings.

Software-Defined Vehicles Loom Closer Every Year

July 12, 2026 by 70 Comments

Vehicles long ago began to incorporate electronics and software, to the point that modern vehicles increasingly have a sort of architecture problem. The software end of things evolves ever more rapidly, but vehicles and their centralized architecture are poorly-suited to continuous updates. As a result, the automotive industry is moving away from static, hardware-defined designs and more toward dynamic, software-defined platforms. In short, the era of software-defined vehicles looms nearer every year.

Flight Sim Tracking From Spatial Audio

July 6, 2026 by 9 Comments

Flight sims are wonderful to play around with to get immersed in the position of a pilot. Racing sims can give you a thrill that can only be beaten by the real thing. However, most of this tech is on the more expensive side, so it would be great if you could use some of the hardware already found in your house. Many Sony headphones already have rotation and movement data built in for spatial audio, so why not start there?

[Nicholas Slattery] had this very idea and has produced an open-source application to connect your headphones straight to your sim. There’s a surprising amount of support built into many headsets that use a known protocol called the Android Head Tracker HID protocol. This allowed [Nicholas] to connect a family of Sony headphones straight into OpenTrack, which is often used with flight sims. The best part is you can still use the headphones as normal with a Bluetooth connection.

If you want to give this a try with your own rig, check out [Nicholas]’s GitHub here. While flight and driving sims might be expensive to put together, it’s never too hard to hack together something to lower that barrier! Whether it’s a flight sim force-feedback joystick or driving sim hand-breaks we got you!
