Inside an Arcade Joystick

If you ever played an arcade game and wondered what was inside that joystick you were gripping, [Big Clive] can save you some trouble. He picked up a cheap replacement joystick, which, as you might expect, has a bunch of microswitches. However, as you can see in the video below, there are some surprising features that make sense when you think about it.

For one, there are plates you can put on the bottom to limit the joystick’s travel depending on the game. That is, some games only want the stick to move up and down or left and right. The knobs are quite nice, and [Clive] mentions the size and thread of the knob with the idea you could use them in different applications. You can also buy replacement knobs if you don’t want to get the whole assembly.

The mechanics are rugged but straightforward. The circuit board is surprisingly stylish but also simple. Still interesting to see what’s inside one of these, even though the schematic is extremely simple.

If you need an excuse to use one of these, how about an arcade table? If you aren’t a woodworker, grab a 3D printer instead.

Using AI To Help With Assembly

Although generative AI and large language models have been pushed as direct replacements for certain kinds of workers, plenty of businesses actually doing this have found that using this new technology can cause more problems than it solves when it is given free reign over tasks. While this might not be true indefinitely, the real use case for these tools right now is as a kind of assistant to certain kinds of work. For this they can be incredibly powerful as [Ricardo] demonstrates here, using Amazon Q to help with game development on the Commodore 64.

The first step here was to generate code that would show a sprite moving across the screen. The AI first generated code in all caps, as was the style at the time of the C64, but in [Ricardo]’s development environment this caused some major problems, so the code was converted to lowercase. A more impressive conversion was done in the next steps, as the program needed to take advantage of the optimizations found in the Assembly language. With the code converted to 6502 Assembly that can run on the virtual Commodore, [Ricardo] was eventually able to show four sprites moving across the screen after several iterations with the AI, as well as change the style of the sprites to arbitrary designs.

Although the post is a bit over-optimistic on Amazon Q as a tool specifically for developers, it might have some benefits over other generative AIs especially if it’s capable at the chore of programming in Assembly language. We’d love to hear anyone with real-world experience with this and whether it is truly worth the extra cost over something like Copilot or GPT 4. For any of these generative AI models, though, it’s probably worth trying them out while they’re in their early stages. Keep in mind that there’s a lot more than programming that can be done with some of them as well.

Transforming Pawn Changes the Game

White pieces on a teal and white chess board. The line of pawns shows three segmented queens in the foreground, one piece being pressed by a man's hand from above in a state between queen and pawn, and the remainder of the pawns in the background in the pawn state.

3D printing has allowed the hobbyist to turn out all sorts of interesting chess sets with either intricate details or things that are too specialized to warrant a full scale injection molded production run. Now, the magic of 3D printing has allowed [Works By Design] to change the game by making pawns that can automatically transform themselves into queens.

Inspired by a CGI transforming chess piece designed by [Polyfjord], [Works By Design] wanted to make a pawn that could transform itself exist in the real world. What started as a chonky setup with multiple springs and a manually-actuated mechanism eventually was whittled down to a single spring, some pins, and four magnets as vitamins for the 3D printed piece.

We always love getting a peek into the trial-and-error process of a project, especially for something with such a slick-looking final product. Paired with a special chess board with steel in the ends, the magnets in the base activate the transformation sequence when they reach the opposite end.

After you print your own, how about playing chess against the printer? We’d love to see a version machined from metal too.

Problem solved? If the problem is supplying enough lithium to build batteries for all the electric vehicles that will be needed by 2030, then a new lithium deposit in Arkansas might be a resounding “Yes!” The discovery involves the Smackover Formation — and we’ll be honest here that half the reason we chose to feature this story was to be able to write “Smackover Formation” — which is a limestone aquifer covering a vast arc from the Rio Grande River in Texas through to the western tip of the Florida panhandle. Parts of the aquifer, including the bit that bulges up into southern Arkansas, bear a brine rich in lithium salts, far more so than any of the brines currently commercially exploited for lithium metal production elsewhere in the world. Given the measured concentration and estimated volume of brine in the formation, there could be between 5 million and 19 million tons of lithium in the formation; even at the lower end of the range, that’s enough to build nine times the number of EV batteries needed.

There are still a lot of unknowns, not least of which is whether any of the lithium in the brine is recoverable, and there are surely technical and regulatory hurdles aplenty. But the mere existence of a brine deposit that rich in lithium that covers such a vast area is encouraging; surely there’s somewhere within the formation where it’ll be possible to extract and concentrate the brine in an environmentally sensitive manner. And, once again just for fun, Smackover Formation.

While not ones to cheer for interstellar catastrophes, we can’t say that we haven’t been rooting for Betelgeuse to go supernova these last few years. Ever since the red supergiant star that sits on Orion’s shoulder started its peculiar dimming a while back, talk among astronomy buffs was that the activity presaged an imminent explosion of the star, one that could make Betelgeuse the brightest object in the night sky for a few months, and possibly make it visible in the daytime as well. As thrilling — and foreboding, at least by ancient astronomy standards — as that sounds, it seems as if the unusual dimming recently observed has a more prosaic explanation: a “Betelbuddy” star. According to astronomers who pored over observations, after ruling out all the other possibilities to explain the dimming, it seems like there must be a smaller star orbiting Betelgeuse that’s periodically plowing a clear spot through the cloud of dust surrounding the dying star. That would explain the periodic dimming and brightening, but why have we not seen this Betelbuddy before? It could be that the smaller star is lost in the giant’s glare, hiding in its halo of incandescent gas. So, don’t hold your breath on seeing a supernova anytime soon.

Do you find password rules annoying? We sure do, and even using a password manager with a generator that can handle all sorts of restrictions like password length and special characters, being told how to generate a password seems silly, especially since the information on what characters a valid password would have seems like valuable clues to potential crackers. But if for some reason you haven’t had enough password pestering, try out the password game. You start by entering a password — we, of course, started with correct horse battery staple — and then deal with the consequences of your obviously poor choices. You’ll be asked to do all the silly stuff that only decreases the entropy of your password, which only makes it harder to remember and easier to guess. We haven’t played it through — it’s way too annoying — but we assume that if you ever actually manage to compose a suitable password, you’ll be asked to change it every 90 days.

And finally, we’ve managed to live long enough now to have cycled completely through all the major music recording modalities except wax cylinders. Having heard them all, we’ve got to agree with the hipsters: vinyl is the best. That’s especially true after watching this fascinating look at the LP record production process, which covers everything from mastering to packaging. The painstaking steps at the beginning are perhaps the most interesting, but anyone who doesn’t appreciate the hot vinyl squeezing out from the press is a cold, heartless monster. The video is only 15 minutes long and mercifully free of narration, so enjoy.

Atari’s Pac-Man Flop: How a Classic Went Off-Course

For fans of retro games, Pac-Man is nothing short of iconic—a game so loved it’s been ported to nearly every console imaginable. But the Atari 2600 version, released in 1982, left players scratching their heads – as laid out in a video by [Almost Something]. Atari had licensed Pac-Man to ride the wave of its arcade success, but the home version, programmed solely by [Todd Fry], missed the mark, turning an arcade icon into a surprising lesson in over-ambitious marketing.

Despite the hype, [Fry] faced an almost impossible task: translating Pac-Man’s detailed graphics and complex gameplay to the Atari’s limited 4 K cartridge with only 128 bytes of RAM. Atari’s strict limitations on black backgrounds and its choice to cut costs by sticking with a 4 K cartridge left the game barely recognizable. The famous pellet-chomping maze became simpler, colors were changed, and the iconic ghosts—reduced to single colors—flickered constantly. And then, Atari went all in, producing twelve million copies, betting on the success of universal appeal. In a twist, Pac-Man did sell in record numbers (over seven million copies) but still fell short of Atari’s expectations, leaving millions of unsold cartridges eventually dumped in a New Mexico landfill.

This debacle even kind of marked Atari’s 1983 decline. Still, Pac-Man survived the hiccup, evolving and outlasting its flawed adaptation on the 2600. If you’re interested in learning more about the ins and outs of game ports, check out the fantastic talk [Bob Hickman] gave during Supercon 2023.
