MicroPython Is This Summer’s Hottest Title For The SNES, Thanks To Claude Fable

July 11, 2026 by 25 Comments

MicroPython, for the uninitiated, is a pared-down version of python meant to run on today’s powerful microcontollers. As impressive as it was for its day, the SNES is not quite in their league in terms of computing power. Time marches on, and so while there may be other indie releases worth mentioning, we’re declaring the hottest SNES game this season to be [Fabian Kübler]’s port of MicroPython.

Well, except he didn’t exactly do the porting himself: the Antrhopic LLM Claude generated the code, and performed most of the testing, as [Fabian]’s test of its new Fable 5 model. A brief pause during an export ban showed that Opus would crash and burn on the same task, but Fable was able to get things quickly back on track. It might be “AI slop” by some definitions, but the port scales 430 out of 468 on MicroPython’s core test/basics, which makes it usable to play some simple python games… slowly.

As you can see for yourself in an embedded emulator if you check out [Fabian]’s blog, spooling up MicroPython takes about twenty seconds at 3.58 MHz, and after that you can watch some sprites bouncing around at a blistering 0.8 FPS. [Fabian] seems satisfied with that performance, and impressed with Fable’s efforts at optimization. What to you think? Does the hardware have much more to give, or is that about it, given the nature of the Pythonic beast? Perhaps some plucky human could become a digital John Henry by producing a better, faster port — if you do, please let us know. If you’d rather just to see what Fable can do, the project is available on GitHub, so you can judge for yourself how sloppy the code is or test out the ROM.

Putting Python onto limited hardware may not to be to everyone’s taste, but there’s a good case to be made for it. The SNES may actually be too limited, though. It makes sense — the kind of micros you run MicroPython on can emulate the SNES.

Reject Modernity, Return To 80s, Learn C.

July 10, 2026 by 114 Comments

We’re not exactly sure how old [SnailMail] is, but he’s probably a member of Generation Alpha considering that to our wizened eyes the lad looks only slightly older than a fetus– which makes it all the more impressive that he’s written his own text editor, from scratch, in C– on a 386. See, [SnailMail] tried to learn the modern way, with IDEs that have code completion and AI integration, but his thoughts couldn’t gel in the modern environment. So he went online and bought an old IBM-compatible complete with monochrome amber monitor, and a whole 4MB of RAM. Big spender that he is, [SnailMail] upgraded that to 8MB.

Rather than fall victim to the siren song of Wolfenstien 3D or SimCity, he set out to learn to code: C, specifically, since that language bridges four decades between [SnailMail] and his new PC. Even more specifically, he got ahold of disks for Borland Turbo C and Turbo C++, which brings back memories for some of us. Of course the lad also had to learn how to use a DOS PC at the same time, but a teen in the 80s with a fresh box would have climbed the same steep learning curve. Some of you probably remember doing so yourselves. Just like you–or the hypothetical teen in the 80s–[SnailMail] did it not by googling or begging Claude for answers, but by digging into books. Many books.

After all the reading, he started with a text editor, something we remember being a pretty big project not given to first year students. Video evidence suggests he pulled it off. He describes how his solution works from about 8:00 in the video, so you greybeards in the audience can judge his work for yourself.

If you’re a member of Gen Alpha reading this and looking to learn to program, we cannot recommend this technique highly enough– [SnailMail] is going to have a better understanding of the underlying logic of computer science than a lot of CS grads being frocked today. Especially when you consider he ends by promising to learn assembly, something we heartily endorse.

3D Printed Scooter Fits In Your Luggage, Some Assembly Required

July 10, 2026 by 17 Comments

Though [Ivan Miranda] calls the 3D printed vehicle in his recent video a motorbike, what he ultimately pulls out of his suitcase is clearly a scooter. Linguistic confusion aside, the “Mirandetta” looks like an awesome build and pulling a scooter out of your suitcase and whizzing past everyone in the taxi line just sounds amazing, especially knowing you made it yourself.

Aside from a whole lot of filament, he’s got a couple of tool batteries for hot-swappable energy that Airport security shouldn’t mind too much — provided you carry them with you, anyway — plus the usual e-bike motor and electronic speed control you might expect, and lawnmower tires which you might not. The narrow 3D printed rims round over the normally-flat tires to make them usable for this application. He seems particularly taken with the bi-stable mechanism he built for the kickstand, and we can’t blame him as we love seeing that kind of thing ourselves. The TPU seat is also a nice touch to keep with ‘everything printed’ vibe.

Now while the finished product does indeed fit into his suitcase, it needs to be completely disassembled. Well, unless you have an over-sized suitcase, perhaps. So our dreams of zooming away from the luggage line from the first paragraph were perhaps a bit premature. Still, from the footage at Prague Maker Faire at the end of the video, it looks like it was a fun enough ride that we can forgive [Ivan] for our overactive imaginations.

If you want an open-source e-bike, we’ve seen those too — but that won’t fit in any kind of suitcase.

Radio-Gaga Is A Toddler Friendly Remote In A Radio

July 9, 2026 by 2 Comments

Humans of all ages like music, but you can’t exactly pass a toddler the aux cable. That’s not to say the younger set don’t have their own particular tastes– they absolutely do, and they absolutely love to take control and inflict them on the rest of us. [nbr23] has a toddler who loves both music and tactile controls, and decided to combine the two for them with a project he calls Radio-Gaga, which is a gutted Panasonic radio that calls up tunes via Home Assistant.

Interestingly enough the radio is now just a remote control– the speaker has been removed along with the rest of the radio hardware. The buttons and dials are still there, though, letting the toddler control what tunes are on offer and at what volume via couple of potentiometers hooked to an ESP32. The sound itself is being served up from the homelab to a USB speaker. There’s one notable flaw with this architecture: if the batteries die on the remote, “Let it Go” does not until an adult intervenes manually or recharges the remote.

One interesting lesson [nbr23] wanted to share was that he was able to improve an unsatisfactorily slow startup time by assigning the device a static IP on his network– apparently the single longest step in getting the tunes going was negotiating a DHCP lease. Skipping that gets the tunes playing in under a second, which is fast enough even for the most impatient of tiny humans.

If you prefer a more self-contained device, we’ve seen toddler jukeboxes that keep storage and speaker built-in, many with NFC control. 

Overpowered RC Car + Gimbal Cam = The Greatest Chase Vehicle We’ve Ever Seen

July 9, 2026 by 8 Comments

Modern cinema relies very heavily on quadrotor drones, because they make for very smooth, very easy to position platforms. From slow pans to chase shots, drones are great– if your shots can be taken at a high enough altitude. Close to the ground, things get a bit dodgier. That’s where [Transistor Man]’s camera chase vehicle comes in— it’s a rover, so it excels close to the ground. In fact, it can’t go anywhere else, except perhaps if provided with a jump. It’s got a hefty gimbal to hold the camera steady on any terrain, a decade-old surplus radio to provide full HD FPV to the remote driver, and a powerful 1/5th scale radio control rally chassis to make it all go. Plus googly eyes, because everything is better with googly eyes.

It looks like an enormous amount of fun to drive, but more importantly it provides smooth, cinematic shots from the professional Sony camera held in the gimbal. One big takeaway is that when 3D printing something that will bounce around this much, you can’t rely on pure strength– flexible filaments are your friend. Just about everything printed ended up remade in TPU if it didn’t start that way. The other takeaway is that we’ve reached enough of a technological plateau that if you scrounge around, you can build something to take a top-of-the-line footage with decade-old castoffs, like the gimbal and radio used in this project, which is a great thing for hobbyists and small studios.

If you can’t find surplus, you could always DIY a gimbal. We’re not filmmakers, but we find ourselves wondering how shots made with this rover would compare to a camera slider.

Die Casting Comes Home

July 9, 2026 by 11 Comments

You don’t normally think of die casting as something to do at home. Pressurized fluids demand respect at all times, which is perhaps in part why we see most projects skipping hydraulics for linear actuators. When the pressurized fluid is molten metal? Well, we’d say don’t try this at home, except that’s exactly what this video by [Know Art] is making us want to do. He’s doing die-cast aluminum, and it looks way easier than we thought it would.

If you’re wondering why anyone would attempt such a thing, it’s for the same reason die-casting has been an industrial powerhouse for the last couple hundred years — you can crank out a lot of parts, very quickly, with excellent detail and dimensional stability. You just need a mold, which in this process is called a die, and a way to squeeze metal into it with some force.

In this case the die was carved on a desktop CNC machine. Depending on how long you want your die to last, you’ll need something hard and heat resistant, like the graphite used in this video. Graphite is also used in constructing the piston for the injector, which is made from a modified hydraulic cylinder and a couple of old trampoline springs.

He first tests the setup with molten wax before moving onto aluminum, as the process is the same regardless: pour the hot liquid in, release the springs to provide the pressure that forces it into the die, and a part is made. It looks easy, if a bit frantic, as you have to work fast before the metal cools in the cylinder.

After CNC milling, EDM machining and all the fun things we’ve learned how to do with lasers and 3D printers, and now this we’ve got to wonder– is there any industrial process you can’t hack onto your desktop? We’ve even seen the chemists get in on the game.

C64 Finally Gets The SRAM Corporate Wouldn’t Pay For

July 8, 2026 by 35 Comments

If you think RAM is expensive now, try putting yourselves in the shoes of a Commodore engineer, circa 1981. RAM was eye-wateringly expensive by modern standards, and Jack Tramiel wanted 64K of the stuff for the next computer — hence the name, Commodore 64 — but he didn’t want to pay for it. The solution was to use cheaper dynamic RAM over the more expensive static RAM that later took over the market in the kilobyte range. That’s a small problem for retrocomputer hobbyists, because while we’re complaining about the price of gigabytes of the stuff, you can’t buy new DRAM chips that fit a Commodore at any price. That’s why [Fabio Battaglia] aka [hkzlab] came up with an adapter board to fit easily-available SRAM chips onto aging C64s. 

Nothing lasts forever: not cold September rain, and not DRAM chips. Heat damage? Internal corrosion? There are probably multiple failure modes, but someday the old stock of chips will run out and the retrocomputer community is going to be ready for it. [Keith Olson] sent us a tip on a video by [The Retro Shack] about this very problem that serves as a good demo of what you get when you put SRAM into a C64. (Thanks [Keith]!) That said, the adapter board on offer is only good for C64s with the 250407 motherboard. If yours is different, you may have to modify the board. But hey, it’s open source, so go ye and do that thing. Let us know via the tips line if you do.
