Game jams are a fun competition in which the aim is to write a game under a particular theme while under a time constraint, usually a weekend.  [Hoani] entered one where the aim was to write a game within the constraints of the Nokia 3310’s user interface: a 94 by 48 pixel grey LCD, a buzzer, and a keypad. His entry was Trick Shot II, a ball-bouncing game running on his game engine, which is cool enough, but making a custom PCB for a Nokia 3310 case to run it on ? Next level. Look away if you don’t like restomods, for a real Nokia 3310 is gutted to take this board. On it is a Pi Pico, the Nokia LCD, which has outlasted the original phone as a part by decades, and a Nokia keypad layout. The first prototype was not a perfect fit because it had a 1.6mm board rather than 1mm. The engine meanwhile is written in Go, and has both graphics and sound APIs. Considering that the Pico’s power exceeds whatever CPU the phone had by many orders of magnitude, we’d imagine it h...

It probably goes without saying that if you send four humans to observe the Moon up close, they’ll see things that those of us stuck here on Earth have never noticed. Luckily for us, they took impeccable notes and brought plenty of cameras, which NASA has shared with the rest of the class as Artemis II: Sights & Sounds of Science . Well, technically it’s called the Artemis II Preliminary Lunar Science Report, but we appreciate the space agency adding a little flair to it and formatting the findings for public consumption. Arguably the most significant observations detailed in the report are the impact flashes on the lunar surface. As you may recall, the trajectory of the Orion spacecraft meant the crew experienced a unique solar eclipse on the sixth day of the mission , giving them an unprecedented close-up view of the darkened Moon. During this time, they were able to see flashes of light with their unaided eyes, which NASA has since confirmed were small rocky fragmen...

Although the demise of the Zilog Z80 processor has long been predicted, it would seem that this moment has finally arrived. The owner of the Zilog name – Littelfuse – recently sent out PCN ZAC26-0074 , notifying customers that they will be taking final orders for the eZ80 and all other microcontroller lines that they currently own. Over at Mouser, eZ80 parts have correspondingly all been marked as “End of Life”. This comes a few years after the original Z80 and its peripherals were discontinued , with the eZ80 still being an alternative until now. Any potential sellers will have to put in their orders today, with orders still accepted until December 21 2026, with final deliveries taking place throughout 2027 as Littelfuse winds down its MCU manufacturing. This means that for commercial customers are least this is pretty much the end of the road for any circuit that still uses the eZ80 or similar. Many of us have fondness for the Z80 , which also has led to a p...

Small displays are affordable and easy to use, but their size can present a challenge. To help address this, [mcer12] created PixelFonts , a family of condensed fonts designed specifically for low-resolution displays, making sure every line holds as much text as it can fit. PixelFonts works alongside either the AdafruitGFX or U8g2 libraries; one writes to the display using the common syntax of the chosen library, and the font itself comes from PixelFonts. Text can be displayed in regular and 3D shadowed versions, as well as in a wide variety of heights and weights. There’s support for accented letters, albeit only in lowercase due to space constraints. Want to make some changes? Every font comes with a BDF file to make alterations as widely accessible as possible. Making the most of every pixel is important with small displays, but there’s more than one way to do so. For example, when it comes to color LCDs, subpixel rendering can improve legibility of small fonts; ano...

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...
