The Abric Romaní site in Spain is rather unique in archeology for one simple reason: the caves in its limestone-rich cliff have seen humanoid occupation for thousands of years. A thick layer of calcium carbonate-based travertine deposit has, over time, covered and largely preserved tools and other implements, including those made of wood. Over many decades of archeological exploration, 597 wooden imprints have been uncovered, with a recent research article by [Palmira Saladié] et al. detailing these findings . Wood is one of those archaeological artefacts that are very elusive due to their fragility, even though we know that wood has been used pretty much everywhere from the first day that a humanoid critter discovered that branches make great clubs and spears, and can also easily be shaped to make them even more useful. The wooden imprints and some larger remains of wooden implements were found, ranging from wooden spears and clubs to trays (see heading image) and tripods. With eno...

Although the asking price of $209 plus shipping seems high for the Radxa Dragon Q8B, featuring the Qualcomm SC8280XP and 8 GB of LPDDR4X, this is 2026, and amid the RAMpocalypse, even the 8 GB LPDDR4X-equipped Raspberry Pi 5 now costs $175. This, to [Jeff Geerling], makes it fair to directly compare the two to see whether you may want to consider this board for more intense computing purposes. There’s also a written summary of the results and details in a GitHub issue, though the direct comparison with the Raspberry Pi 5 is in the video. Although this Qualcomm SoC isn’t new, its primary use is for Windows laptops , which gives somewhat of a hint as to what its performance may be like, tempered by the fact that it was announced in 2021. The Dragon QXB offers about 2x everything over the RPi5, plus Windows and UEFI support. For Linux, it appears that you still need customized images, which seems perplexing in light of the UEFI aspect. You also have to pick between differe...

Valve recently began shipping its long-awaited VR headset, the Steam Frame. Now, there is a hardware reference repository that includes everything a budding modder might need, and then some. No need to 3D scan or break out the calipers if one wants to design their own add-ons. Want to design and 3D print some add-ons, or a carrying case, or some other doodad? There’s no need to break out the calipers or 3D scan the hardware. The repository contains STEP format models of the VR core module, head strap, and controllers, so it’s as easy as possible to design things that’ll fit. The location of the IR tracking LEDs embedded in the controllers is also documented, so one can ensure their design doesn’t occlude them. That’s not all. The Frame has a user-accessible hardware expansion port at its front. This port exposes two interfaces: high-speed MIPI camera and PCI Express. This expansion port is documented in the repository, and even has a simple reference de...

As a portable media player, Microsoft’s Zune simply couldn’t compete with Apple’s juggernaut iPod — the latter essentially becoming the de facto personal media player until smartphones took over. But in 2026 it might be Microsoft that gets the last laugh, as thanks to [rsheldiii] the Zune can now play Super Mario 64 . The software is based on sm64ex, and notably doesn’t include the ROM file necessary to actually run the game. But presuming a legal dump of a cartridge has been done, building and loading it onto a Zune HD is straightforward enough. From there the player is presented with a controller interface on the device’s touchscreen overlaid with the video output from the game. Some interesting things are happening in the background here as well, like using NVIDIA’s Tegra tools to pre-compile shaders so the 2009-era processor can handle the rest of the gameplay. Although it didn’t enjoy the mainstream success of the iPod, the Zune was...

The sad reality is that all consumer electronics are going to be e-waste eventually. [Cory Whitesell] was determined his old NEC ProSpeed 286 Laptop wouldn’t meet that fate until absolutely necessary, so when his attempts at repairs failed, his efforts pivoted to create a retro battlestation from the stylish old machine . That screen looks too good to be stock, but otherwise you can’t tell from this angle. Externally, it looks pretty well stock, and [Cory] has retained as much of the internals as possible. The original power supply remains intact, with power taken off the original HDD’s molex connector. Said power drives a Raspberry Pi, which is small enough to fit inside without any gutting. The original keyboard connects easily enough via a PS/2 to USB adapter, while the passive-matrix LCD has been replaced with a modern screen of the same dimensions. You’d have to be a pretty hard-core purist to mourn that last change. With emulation on the Pi, he can still...

Recently [Riley] got his paws on an old Prusa i3 FDM printer that had clearly seen better days, with a hot-end that had suffered an explosive blow-out. For the project he had in mind this was of course perfect, as his intention was to replace the hot-end with a syringe system for embedded 3D printing (E3DP) , which uses a supportive medium to allow for the printing of materials and structures that would be impossible with just air. Generally in additive manufacturing (AM) methods like fused deposition modelling (FDM) the material is extruded onto a build plate or a previous layer where it solidifies. This works great for materials like thermoplastics, but for other materials having only the surrounding air as support is just a recipe for a big mess. With E3DP the liquid is instead extruded into a supportive material at a selectable depth and volume, opening up a whole range of possibilities. In a 2026 review article by [Rongji Tang] et al. in  Frontiers in Materials provide an ove...

Flying and driving simulators can go as far as money will take you, and at some point it might end up being cheaper to buy a plane or race car than to keep adding capabilities to some of the sim rigs we’ve seen. But it can also be a fairly affordable hobby as well, with entry-level components being within reach for many. The price can drop precipitously from there too, provided some parts can be sourced and a 3D printer is made available, and [Jason] is demonstrating one of the lowest-cost H-shifters we’ve seen which only uses two parts at its core . The two components only cover the electronics for the build, but this gets almost everything needed for the shifter squared away. A joystick like those found inside many game controllers is paired with an Arduino Pro Micro, with a very straightforward wiring configuration between them. These components are paired with a prototype 3D printed case and shift knob which provides the H pattern of choice. From there it’s as sim...
