A series of wooden rectangles are arranged vertically around the edges of a dark wooden base, reminiscent of a very tall radial fan. Light glows from the base up the slots between the vanes. a cord runs from behind the dark base to a small puck of the same color. The setup sits on a light grey table in front of a light grey wall.

A Beautiful Lamp-Inspired PC Case

September 23, 2024 by 5 Comments

Sometimes you see something super cool and think of how it would be really neat if applied in a totally different context. [MXC Builds] saw an awesome lamp from [karacreates], but decided it would be better as a PC case.

We love seeing how different techniques can be used in conjunction to make something that no one method could produce on its own, and for this build, we see [MXC Builds] use 3D printing, laser cutting, CNC, sewing, soldering, and traditional woodworking techniques.

A large part of the video is spent on the CNC process for the walnut base and power button enclosure for the build. As with any project, there are a few places requiring some creative use of the tools on hand, like the walnut piece for the base being too tall for the machine’s usual z-calibration puck or any of [MXC Builds]’s bits to do in one pass, and it’s always interesting to see how other makers solve these issues.

If you’re looking for other beautiful casemods, how about a transparent PS2 or this Art Deco number? Before you go, may we bend your ear about how PC Cases are Still Stuck in the Dark Ages?

Custom Mini-Neon Signs In 10 Minutes

September 23, 2024 by 24 Comments

Sometimes, you see a project that isn’t a technical powerhouse but just looks so good you can’t help but think about duplicating it. That’s how we felt with the mini-neon signs made by [makerverse]. From an electronics point of view, it is just some filament LEDs and a 3D-printed casing. But, as you’ll see in the video below, these look like little miniature neon signs, and they look great.

Although we might use a different set of tools to get there, the idea is to create your text in DXF, extrude it in CAD, and then print a dark shell with a light or translucent center using a filament change. Glow-in-the-dark filament is also an option. Obviously, if you are handy in any CAD tool, you could easily pull this off.

Revisiting 1990’s Mac Games That Never Were

September 23, 2024 by 17 Comments

[John Calhoun] was digging around their old MAC hard drives, revisiting some abandoned shareware games they wrote over three decades ago, and has uploaded the recovered disk images to GitHub for everyone to take apart and play with. This repository has a few of the games complete with their development files and the compiler environment, a mixture of Think Pascal and C.

Back then, [John] had a solid mantra when creating projects, specifically prototyping fast and abandoning things quickly if they were not working out. The blog shows a list of twenty-eight projects, of which only five ever made it to release, with all the rest left to rot. This is reminiscent of the attitude around Silicon Valley of moving fast and breaking things. Anyway, reasons for ditching a project ranged from ‘too much sprite work’ for a D’n’D style game to simply ‘not fun’ for some with clunky control mechanisms. [John] even abandoned a neat-looking steampunk flight simulator due to the sheer amount of work needed. Of course, it’s not all lost effort. Much of the code written was reused across multiple projects; after all, there’s no point in re-writing a cosine lookup table if you’ve already got one kicking around in another project.

Still, it’s a fun trip down memory lane, looking deep into projects that never were and the development journey to becoming a successful programmer.

While it isn’t hard to find old Macintosh hardware, some are not in great shape. Here’s a fun Hackintosh project that uses retro parts. [John] was featured a while back, with his homage to his first mac, a sleek Rpi-powered eInk desk ornament. Finally, we can’t talk about recovering retro software without looking in detail at the floppy disk themselves.

Fukushima Daiichi: Cleaning Up After A Nuclear Accident

September 23, 2024 by 47 Comments

On 11 March, 2011, a massive magnitude 9.1 earthquake shook the west coast of Japan, with the epicenter located at a shallow depth of 32 km,  a mere 72 km off the coast of Oshika Peninsula, of the Touhoku region. Following this earthquake, an equally massive tsunami made its way towards Japan’s eastern shores, flooding many kilometers inland. Over 20,000 people were killed by the tsunami and earthquake, thousands of whom were dragged into the ocean when the tsunami retreated. This Touhoku earthquake was the most devastating in Japan’s history, both in human and economic cost, but also in the effect it had on one of Japan’s nuclear power plants: the six-unit Fukushima Daiichi plant.

In the subsequent Investigation Commission report by the Japanese Diet, a lack of safety culture at the plant’s owner (TEPCO) was noted, along with significant corruption and poor emergency preparation, all of which resulted in the preventable meltdown of three of the plant’s reactors and a botched evacuation. Although afterwards TEPCO was nationalized, and a new nuclear regulatory body established, this still left Japan with the daunting task of cleaning up the damaged Fukushima Daiichi nuclear plant.

Removal of the damaged fuel rods is the biggest priority, as this will take care of the main radiation hazard. This year TEPCO has begun work on removing the damaged fuel inside the cores, the outcome of which will set the pace for the rest of the clean-up.

New Release Of Vision Basic: Hot New Features!

September 23, 2024 by 7 Comments

As the Commodore 64 ages, it seems to be taking on a second life. Case in point: Vision BASIC is a customized, special version of the BASIC programming language with a ton of features to enable Commodore 64 programs to be written more easily and with all sorts of optimizations. We’ve tested out both the original 1.0 version of Vision BASIC, and now with version 1.1 being released there are a whole host of tweaks and updates to make the experience even better!

One of the only limitation of Vision BASIC is the requirement for expanded RAM. It will not run on an unexpanded C64 — but the compiled programs will, so you can easily distribute software made using Vision on any C64. A feature introduced in version 1.1 is support for GeoRAM, a different RAM expansion cartridge, and modern versions of GeoRAM like the NeoRAM which has battery-backed RAM. This allows almost instantaneous booting into the Vision BASIC development environment.

StratoSoar Glider Flies Itself From High Altitude

September 23, 2024 by 32 Comments

As the technology available to the average hacker and maker gets better and cheaper each year, projects which at one time might have only been within the reach of government agencies are inching closer to our grasp. Take for example the impressive work [Charlie Nicholson] has put into his StratoSoar series of autonomous gliders.

Dropped from several thousand feet by a high-altitude balloon, the glider’s avionics are designed to either guide it along a series of waypoints or head directly towards a specific target. Once at the given coordinates it can initiate different landing programs, such as spiraling down to the ground or releasing an onboard parachute. It’s an ambitious combination of custom hardware and software, made all the more impressive by the fact that it’s been put together by somebody who’s not yet old enough to have a driver’s license.

[Charlie] originally experimented with developing his own airframe using 3D printed components, but at least for now, found that a commercial off-the-shelf foam glider was a more practical option. All that’s required is to hollow out some areas to mount the servos, battery, and the avionics. This takes the form of a custom PCB that contains a ATSAMD21G18 microcontroller, an ICM-20948 inertial measurement unit (IMU), connections for GPS and LoRa modules, as well as several onboard sensors and some flash storage to hold collected data.

The goal of this open source project is to make these sort of unmanned aerial vehicles (UAVs) cheaper and more accessible for hobbyists and researchers. Eventually [Charlie] hopes to offer kits which will allow individuals to build and operate their own StratoSoar, making it even easier to get started. He’s currently working on the next iteration of the project that he’s calling StratoSoar MK3, but it hasn’t had a flight test yet.

We’ve seen various attempts to launch autonomous gliders from balloons in the past, but none from anyone as young as [Charlie]. We’re eager to see the StratoSoar project develop, and wish him luck in future test flights.

Hands-on With New IPhone’s Electrically-Released Adhesive

September 22, 2024 by 65 Comments

There’s a wild new feature making repair jobs easier (not to mention less messy) and iFixit covers it in their roundup of the iPhone 16’s repairability: electrically-released adhesive.

Here’s how it works. The adhesive looks like a curved strip with what appears to be a thin film of aluminum embedded into it. It’s applied much like any other adhesive strip: peel away the film, and press it between whatever two things it needs to stick. But to release it, that’s where the magic happens. One applies a voltage (a 9 V battery will do the job) between the aluminum frame of the phone and a special tab on the battery. In about a minute the battery will come away with no force, and residue-free.

There is one catch: make sure the polarity is correct! The adhesive releases because applying voltage oxidizes aluminum a small amount, causing Al3+ to migrate into the adhesive and debond it. One wants the adhesive debonded from the phone’s frame (negative) and left on the battery. Flipping the polarity will debond the adhesive the wrong way around, leaving the adhesive on the phone instead.

Some months ago we shared that Apple was likely going to go in this direction but it’s great to see some hands-on and see it in action. This adhesive does seem to match electrical debonding offered by a company called Tesa, and there’s a research paper describing it.

A video embedded below goes through the iPhone 16’s repairability innovations, but if you’d like to skip straight to the nifty new battery adhesive, that starts at the 2:36 mark.
