Supercon 2025 Badge Gets Vintage Star Trek Makeover

October 29, 2025 by Tom Nardi 3 Comments

There are still a few days before the doors open on this year’s Hackaday Supercon in Pasadena, but for the most dedicated attendees, the badge hacking has already begun…even if they don’t have a badge yet.

By referencing the design files we’ve published for this year’s Communicator badge, [Thomas Flummer] was able to produce this gorgeous 3D printed case that should be immediately recognizable to fans of the original Star Trek TV series.

Metal hinge pin? Brass inserts? Scotty would be proud.

Although the layout of this year’s badge is about as far from the slim outline of the iconic flip-up Trek communicator as you can get, [Thomas] managed to perfectly capture its overall style. By using the “Fuzzy Skin” setting in the slicer, he was even able to replicate the leather-like texture seen on the original prop.

Between that and the “chrome” trim, the finished product really nails everything Jadzia Dax loved about classic 23rd century designs. It’s not hard to imagine this could be some companion device to the original communicator that we just never got to see on screen.

While there’s no denying that the print quality on the antenna lid is exceptional, we’d really like to see that part replaced with an actual piece of brass mesh at some point. Luckily, [Thomas] has connected it to the body of the communicator with a removable metal hinge pin, so it should be easy enough to swap it out.

Considering the incredible panel of Star Trek artists that have been assembled for the Supercon 2025 keynote, we imagine this won’t be the last bit of Trek-themed hacking that we see this weekend — which is fine by us.

Building A Handheld Pong Game

March 21, 2025 by Lewin Day 2 Comments

Pong was one of the first video games to really enter the public consciousness. While it hasn’t had the staying power of franchises like Zelda or Call of Duty, it nonetheless still resonates with gamers today. That includes [Arnov Sharma], who put together this neat handheld version using modern components.

An ESP32 development board serves as the brains of the operation. Capable of operating at many hundreds of megahertz, it has an excessive amount of power for an application as simple as this. Nonetheless, it’s cheap, and it gets the job done. It’s paired with an SSD1306 OLED screen of 124 x 32 resolution. That might not sound like much, but it’s plenty when you’re just drawing two paddles and a ball bouncing between them. Control is via a pair of SMD push buttons for a nice responsive feel.

What’s really neat, though, is the presentation. [Arnov] wrapped the electronics in a neat bean-shaped housing that vaguely apes game controllers of the 16-bit era. Indeed, [Arnov] explains that it was inspired by the Sega Genesis specifically. It looks great with the black PCBs integrated so nicely with the bright orange 3D printed components, and looks quite comfortable to use, too.

It might be a simple project, but it’s done rather well. Just by thinking about color choices and how to assemble the base components, [Arnov] was able to create an attractive and functional game that’s a lot more eye catching than some random boards thrown in an old project box. Indeed, we’ve featured stories on advanced FR4/PCB construction techniques before, too. Meanwhile, if you’re creating your own projects with similar techniques, don’t hesitate to let us know!

3D Printed Case Turns Pixel 6 Pro Into Palmtop

January 3, 2025 by Tom Nardi 33 Comments

Despite initial interest in the 1990s and early 2000s, palmtop computers never really took off. Realistically most consumers were probably satisfied enough with smartphones as they became more widely available, but those of us who would prefer a real keyboard on our mobile devices are still feeling the pain. Today there are still a few commercial palmtop-like machines out there, but they aren’t exactly mainstream.

Which is why this 3D printed case for the Pixel 6 Pro from [TypingCat] is so interesting. It takes a relatively popular and capable contemporary phone, pairs it with a physical keyboard, and manages to create something that looks quite practical. Thanks to Termux, you can even get a fairly usable Linux environment going on the thing.

There aren’t too many components at play here, but still, we appreciate the fact that [TypingCat] provided links for not only the specific Bluetooth keyboard used, but the fasteners required to hold the three printed parts together. A link is also provided to the Termux-Desktops project, which allows you to get a Linux X11 desktop environment running on Android. It’s not the pocket Linux computer of our dreams, but it’s pretty close.

While the Pixel 6 Pro is a solid enough choice to base this project around, we’re interested in seeing if the community will come up with variants of this case to hold other similarly sized phones. It’s interesting to note that [TypingCat] has decided to use the “No Derivatives” variant of the Creative Commons license for the bottom half of the case. But since the top half is a remix of an existing Pixel 6 Pro case from [JoshCraft3D], it carries a more permissive license and must be distributed separately. Long story short, folks can create and distribute custom versions of the phone-side of this case, but the bottom needs to remain the same.

If you’ve got filament to ~~burn~~ extrude and would rather have a more pure Linux experience, we saw a printable Raspberry Pi Zero palmtop a couple months back that looked quite promising.

FlatMac: Building The 1980’s Apple IPad Concept

December 7, 2024 by Maya Posch 16 Comments

The Apple FlatMac was one of those 1980s concepts by designer [Hartmut Esslingers] that remained just a concept with no more than some physical prototypes created. That is, until [Kevin Noki] came across it in an Apple design book and contacted [Hartmut] to ask whether he would be okay with providing detailed measurements so that he could create his own.

Inside the 3D printed enclosure is a Raspberry Pi 4 running an appropriately emulated Macintosh, with a few modern features on the I/O side, including HDMI and USB. Ironically, the screen is from a 3rd generation iPad, which [Kevin] bought broken on EBay. There’s also an internal floppy drive that’s had its eject mechanism cleverly motorized, along with a modified USB battery bank that should keep the whole show running for about an hour. The enclosure itself is carefully glued, painted and sculpted to make it look as close to the original design as possible, which includes custom keycaps for the mechanical switches.

As far as DIY projects go, this one is definitely not for the faint of heart, but it’s fascinating to contrast this kind of project that’s possible for any determined hobbyist with the effort it would have taken forty years ago. The only question that’s left is whether or not the FlatMac would have actually been a practical system if it had made it to production. Although the keyboard seems decent, the ergonomics feel somewhat questionable compared to something more laptop-like.

Printed Rack Holds Pair Of LattePandas In Style

October 8, 2024 by Tom Nardi 25 Comments

ARM single-board computers like the Raspberry Pi are great for some applications — if you need something that’s energy efficient or can fit into a tight space, they’re tough to beat. But sometimes you’re stuck in the middle: you need more computational muscle than the average SBC can bring to the table, but at the same time, a full-size computer isn’t going to work for you.

Luckily, we now have options such as the LattePanda Mu powered by Intel’s quad-core N100 processor. Put a pair of these modules (with their associated carrier boards) on your desktop, and you’ve got considerable number-crunching capabilities in a relatively small package. Thanks to [Jay Doscher] we’ve got a slick 3D printed rack that can keep them secure and cool, complete with the visual flair that we’ve come to expect from his creations.

Portable Multi-SDR Rig Keeps Your Radios Cool

September 3, 2024 by Tom Nardi 12 Comments

With as cheap and versatile as RTL-SDR devices are, it’s a good idea to have a couple of them on hand for some rainy day hacking. In fact, depending on what signals you’re trying to sniff out of the air, you may need multiple interfaces anyway. Once you’ve amassed this arsenal of software defined radios, you may find yourself needing a way to transport and deploy them. Luckily, [Jay Doscher] has you covered.

His latest creation, the SDR SOLO, is a modular system for mounting RTL-SDRs. Each dongle is encased in its own 3D printed frame, which not only protects it, but makes it easy to attach to the base unit. To keep the notoriously toasty radios cool, each frame has been designed to maximize airflow. You can even mount a pair of 80 mm fans to the bottom of the stack to really get the air moving. The current design is based around the RTL-SDR Blog V4, but could easily be adapted to your dongle of choice.

In addition to the row of SDR dongles, the rig also includes a powered USB hub. Each radio connects to the hub via a short USB cable, which means that you’ll only need a single USB cable running back to your computer. There’s also various mounts and adapters for attaching antennas to the system. Stick it all on the end of a tripod, and you’ve got a mobile radio monitoring system that’ll be the envy of the hackerspace.

As we’ve come to expect, [Jay] put a lot of thought and effort into the CAD side of this project. Largely made of 3D printed components, his projects often feature a rugged and professional look that really stands out.

FauxTRS Is Definitely Not A Trash 80

July 22, 2024 by Jenny List 12 Comments

Among the 8-bit home micro boom from the late 1970s through early 1980s, the introduction to computing for many wasn’t a pricey Apple or Commodore, instead it was the slightly lower budget machine from Radio Shack. The TRS-80 series of computers live on and have a loyal following among retro computing enthusiasts. But like all such machines the original hardware is harder to find in 2024, so how about the TRS-80 experience without the failing vintage parts? The FauxTRS from [Jpasqua] is just that, the feel of a Model 3 or Model 4, powered by a Raspberry Pi.

In a sense then, this is a very well-designed case for a Raspberry Pi that looks a lot like the Tandy of old. With a modern LCD and keyboard it could just as easily be a normal desktop machine, but when the emulator fires up it does indeed look very much like a small version of the real thing. You can download the STL files from Printables, and for the cost of a few extra parts you can have one too.

Alternatively, if a faux TRS doesn’t do it for you, there’s always the chance of making a more real one.
