Asteroids: Kessler Syndrome Edition

August 5, 2024 by 6 Comments

Asteroids, the late-70s arcade hit, was an immensely popular game. Often those with the simplest premise, while maintaining a fun, lighthearted gameplay have the most cultural impact and longest legacy. But, although it was popular, it doesn’t really meet the high bar of scientific fidelity that some gamers are looking for. That’s why [Attoparsec] built the Kessler Syndrome Edition of this classic arcade game.

The Kessler Syndrome is a condition where so much man-made debris piles up in low-Earth orbit that nothing can occupy this orbit without getting damaged or destroyed by the debris, and thus turning into more debris itself in a terrible positive feedback loop. [Attoparsec] brings this idea to Asteroids by reprogramming the game so that asteroids can be shot into smaller and smaller pieces but which never disappear, quickly turning the game into a runaway Kessler Syndrome where the chance of survival is extremely limited, and even a destroyed player’s ship turns into space junk as well.

To further the scientific accuracy and improve playability, though, he’s added a repulsor beam mechanism which can push the debris a bit and prolong the player’s life, and also added mass effect reactions so that even shooting bullets repels the player’s ship a bit. The build doesn’t stop with software, either. He also built a custom 70s-style arcade cabinet from the ground to host the game.

Asteroids is still a popular platform for unique builds like this. Take a look at a light-vector game using lasers to create the graphics, or this tiny version of the game that uses a real CRT.

Tiny Arcade Uses Tiny CRT

July 27, 2022 by 16 Comments

Restoring vintage electronics is a difficult hobby to tackle. Even the most practical builds often have to use some form of modern technology to work properly, or many different versions of the machine need to be disassembled to get a single working version. Either way, in the end someone will be deeply hurt by the destruction of anything antique, except perhaps with [Marco]’s recent tiny arcade with a unique CRT display.

The CRT is a now-obsolete technology, but Arcade and MAME purists often seek them out because of the rounded screen and vintage feel these devices have when compared to modern LCD or LED displays. For a build this small, though, [Marco] couldn’t just use parts from an old TV set as there wouldn’t be clearance in the back of the cabinet. An outdated video conferencing system turned out to have just the part he needed, though. It has a CRT mounted perpendicularly to a curved screen in order to reduce the depth needed dramatically.

The final build uses a tiny Namco system meant to plug into the RCA jack on a standard TV, but put in a custom case that makes it look like an antique video game cabinet. It’s an interesting build that doesn’t destroy any valuable antique electronics, while still maintaining a classic arcade feel. If you’re building a larger arcade cabinet which will still satisfy the purists out there, make sure you’re using a CRT with the right kind of control system.

No Tool Left Behind With The Help Of Homemade Shadow Boards

June 21, 2022 by 38 Comments

Shadowed tool storage — where a tool outline shows at a glance what’s missing from storage — is a really smart way to keep your shop neat. They’re also super important for cases where a tool left behind could be a tragedy. Think, where’s-that-10-mm-socket-while-working-on-a-jet-engine? important. (It’s always the 10-mm socket.)

But just because shadow boards are smart, doesn’t mean they’re easy to make. That’s why [Scott Prince] came up with this semi-automated method for making toolbox shadow boards. The job of tracing around each tool on some sort of suitable material and cutting out the shapes seems straightforward, but the trick comes in organizing the outlines given the space available and the particular collection of tools.

[Scott]’s method starts with capturing images of each individual tool. He used a PiCam and a lightbox housed, strangely enough, in a storage bench; we’d love to hear the full story behind that, but pretty much any digital camera would do for the job. After compensating for distortion with OpenCV, cropping the images, and turning the image into a vector outline of the tool, [Scott] was left with the task of putting the tools into logical groups and laying them out sensibly. After tweaking the tool outlines and adding finger cutouts for easy pickup, [Scott] put his CNC router to work. He chose to use a high-density polyethylene product made by his employer, which looks fantastic, but MDF would work fine too.

We have to admit to a fair degree of toolbox envy now that we’ve seen what shadow boards can do. We’re a bit torn, though — [Zach Friedman]’s Gridfinity storage system has a lot going for it, too.

Miniature Space Invaders game

Arduino And An OLED Make This Space Invaders Cabinet Tiny

January 12, 2022 by 15 Comments

For as simple as it appears now, Space Invaders was one machine from the Golden Age of video games that always seemed to have a long line waiting for a chance to lose a couple of quarters. And by way of celebrating the seminal game’s influence, [Nick Cranch] has executed what might just be the world’s smallest Space Invaders replica.

It appears that this started mainly as an exercise in what’s possible with what’s on hand, which included a couple of quite small OLED displays. For the build photos it looks like there’s an Arduino Nano running the show; [Nick] relates that the chosen hardware proved challenging, and that he had to hack the driver library to make it work. Once he got a working game, [Nick] didn’t rest on his laurels. Rather, he went the extra mile and built a miniature cabinet to house everything in.

The video quality below may be poor, but it’s more than enough to see how much work he put into detailing the cabinet. The graphics of the original US release of the game cabinet are accurately represented, right down to the art on the front glass. The cabinet itself is made from 1.5 mm plywood which he cut by hand. It even looks like he recreated the original scheme of cellophane overlays on the monochrome screen to add a little color to the game. Nice touch!

We really appreciate the attention to detail here, with our only quibble being no schematics or code being posted. Hopefully, we’ll see those later, but for now, this looks like a fun project and a nice trip down memory lane. But if you think it’s too small, no worries — we’ve got a much, much bigger version of the game too.

Solid Oak Arcade Cabinet: When Particle Board Won’t Do

January 8, 2021 by 25 Comments

Having an arcade cabinet of one’s own is a common dream among those who grew up during the video game arcade heyday of the 80s and early 90s. It’s a fairly common build that doesn’t take too much specialized knowledge to build. This cabinet, on the other hand, pulled out all of the stops for the cabinet itself, demonstrating an impressive level of woodworking expertise.

The cabinet enclosure is made with red oak boards, which the creator [Obstreperuss] sawed and planed and then glued together to create the various panels (more details are available on his Imgur album). The Mario artwork on the sides and front aren’t just vinyl stickers, either. He used various hardwoods cut into small squares to create pixel art inlays in the oak faces. After the fancy woodwork was completed, the build was finished out with some USB arcade controllers, a flat-panel screen, and a Raspberry Pi to run the games.

While the internals are pretty standard, we have to commend the incredible quality of the woodworking. It’s an impressive homage to classic arcade machines and we wouldn’t mind a similar one in our own homes. If you’re lacking the woodworking equipment, though, it’s possible to get a refined (yet smaller) arcade cabinet for yourself with a 3D printer instead.

One Man’s Quest To Build His Own Speakers

October 23, 2018 by 49 Comments

Why build your own stereo speakers? Some people like to work on cars in their garage. Some people build fast computers. Others seek the perfect audio setup. The problem for a newcomer is the signal to noise ratio among audiophile experts. Forums are generally filled with a vocal group of extremists obsessing on that last tiny improvement in some spec.  It can be hard for a beginner to jump in and learn the ropes.

[Ynze] had this problem. He’d finished a custom amplifier and decided to build his own speakers. He found a lot of spirited debates about what was important for good speakers. He tried to wade through the discussions and determine which things had real practical value. The results and his speaker build are documented in a post that you’ll want to check out if you would like to design and build your own speakers.

Some of the topics ranged from solder type to capacitor construction and 700 Euro capacitors. [Ynze’s] goal was to build something that sounded good while keeping costs in line. He claims he spent about 250 Euro and wound up with speakers equivalent to 750 Euro store-bought speakers.

The DIN Rail And How It Got That Way

September 13, 2018 by 56 Comments

Unless you’ve spent some time in the industrial electrical field, you might be surprised at the degree of integration involved in the various control panels needed to run factories and the like. Look inside any cabinet almost anywhere in the world, and you’ll be greeted by rows of neat plastic terminal blocks, circuit breakers, signal conditioners, and all manner of computing hardware from programmable logic controllers right on to Raspberry Pis and Arduinos.

A well-crafted industrial control panel can truly be a thing of beauty. But behind all the electrical bits in the cabinet, underneath all the neatly routed and clearly labeled wires, there’s a humble strip of metal that stitches it all together: the DIN rail. How did it come to be, and why is it so ubiquitous?
