Wizards Slay The Dragon That Lays The Golden Egg

January 11, 2023 by 77 Comments

Hail, and well met adventurers! There’s rumors of dark dealings, and mysterious machinations from that group of Western mystics, Wizards of the Coast (WotC). If this pernicious plot is allowed to succeed, a wave of darkness will spread over this land of Open Source gaming, the vile legal fog sticking to and tainting everything it touches. Our quest today is to determine the truth of these words, and determine a defense for the world of open gaming, and indeed perhaps the entire free world! Beware, the following adventure will delve into the bleak magic of licensing, contract law, and litigation.

Ah, Dungeons and Dragons. The original creation of Gary Gygax, refined by countless others, this table-top role-playing game has brought entertainment and much more to millions of players for years. In 2000, WotC made a decision that opened the mechanics of that universe to everyone. The 3rd Edition of Dungeons and Dragons was released under the Open Gaming License, a very intentional port of Open Source licensing to table-top gaming — obviously inspired by the GNU Public License. Ryan Dancey was one of the drivers behind the new approach, and made this statement about it:

I think there’s a very, very strong business case that can be made for the idea of embracing the ideas at the heart of the Open Source movement and finding a place for them in gaming. […] One of my fundamental arguments is that by pursuing the Open Gaming concept, Wizards can establish a clear policy on what it will, and will not allow people to do with its copyrighted materials. Just that alone should spur a huge surge in independent content creation that will feed into the D&D network.

Roll-On Deodorant Controller Heats Up Racing Game

January 10, 2023 by 24 Comments

What do you get when you combine roll-on deodorant containers and a soccer ball with an optical mouse and an obscure 90s Japanese video game about racing armadillos? Well, you get a pretty darn cool controller with which to play said game, we must admit.

We hardly knew they were still making roll-on deodorant, and [Tom Tilley] is out here with three empties with which to hack. And hack he does — after thoroughly washing and drying the containers three, he sawed off the ball-holding bit just below the business part and fit each into the roll-on’s lid. Then [Tom] constructed a semi-elaborate cardboard-and-hot-glue thing to hold them in an equilateral triangle formation. Out of nowhere, he casually drops a fourth modified roll-on ball over an optical mouse, thereby extending the power of lasers to the nifty frosted orb.

Finally, [Tom] placed the pièce de résistance — the soccer ball — on top of everything. The mouse picks up the movement through the middle roll-on, and the original three are there for stability and roll-ability purposes. At last, Armadillo Racing can be played in DIY style. Don’t get it? Don’t sweat it — just check out the brief build video after the break.

Tetris Joins Minecraft And DOOM In Running A Computer

January 10, 2023 by 6 Comments

There is a select group of computer games whose in-game logic is enough for them to simulate computers in themselves. We’ve seen it in Minecraft and DOOM, and now there’s a new player in town from a surprising quarter: Tetris.

One might wonder how the Russian falling-blocks game could do this, as unlike the previous examples it has a very small playing field. And indeed it’s not quite the Tetris you’re used to playing, but a version played over an infinite board. Then viewed as a continuous progression of the game it can be viewed as somewhat similar to the tape in a Turing machine.

The various moves and outcomes are referred to through a Tetris scripting language, so states can be represented by different sets of blocks and holes while logic elements can be be built up using the various shapes and the game logic. From those a computer can be built, represented entirely in Tetris moves and shapes. It’s a little mind-bending and we’d be lying if we said we understood every nuance of it, but seemingly it works well enough to run the game from within itself.. If it had the catchy music from the NES version, we’d declare it perfect.

Hungry for more? Here’s DOOM doing some adding, and of course Minecraft has a rich computing history.

Is It A Game? Or A Calculator?

January 6, 2023 by 27 Comments

If you are a certain age, you probably remember the Mattel Football game. No LCD screen or fancy cartridges. Just some LEDs and a way to play football when you should be in class. While these might seem primitive to today’s kids, they were marvels of technology in the 1970s when they came out. [Sean Riddle] looks, well, not exactly at the games, but more like in them. As it turns out, they used chips derived from those made for calculators.

[Sean’s] post is a glimpse into this world of over four decades past. Football was actually the second electronic game from Mattel. The first one was Auto Race. There were also games called Space Alert, Baseball, and Gravity. Inside each are quad in-line packages with 42 pins, a Rockwell logo, and a custom part number.

Logic Gate Game Is Fun AND Educational

December 30, 2022 by 1 Comment

How well do you know your logic gates? For their final submission for STEM Projects class, [BKriet] gamified the situation using a Raspberry Pi Pico, some blinkenlights, and a not-insignificant amount of 3D printing. The result is Name! That! Gate!, a fun and educational toy that [BKriet] ultimately donated back to the class (that’s a hot move in our book).

The objective of this game is to figure out which logic gate is being used to make the output shown on the screen, given A, B, and/or C as inputs. There are ten stages to the game, and each correct stage awards the player 14 points, for a perfect score of 140. Although a random gate is loaded for every stage, code ensures that no gate is ever repeated during a single game.

This project is completely open source, so the gate is wide open. Don’t have a 3D printer? Here’s a big set of PCB logic gates, but really, you can make logic gates out of almost anything.

Self-Hosted Gaming With Friends

December 26, 2022 by 27 Comments

One of the best parts of gaming is gaming with friends, but often this requires everyone involved to have the same expensive piece of hardware. Almost everyone has a computer with a browser already, though, so if you’d like to play online with friends who don’t have the same gaming machine as you, they can play along now simply by opening a web browser thanks to this project called Qwantify.

There are a few requirements to get this to work, though. At least one person needs to have a computer with a GPU to run the docker container that hosts the game, but once that’s done anyone with a browser can connect to it and play. The entire project is open source as well, and since it’s currently a very young project there is only support for AMD and Intel GPUs but it does have a fairly intuitive user interface as well as some other features like allowing for various gaming peripherals and supporting streaming gameplay to Twitch and YouTube.

Being able to host your own gaming server is pretty common in some games like Minecraft, but we are excited to see something that is self-hosted take this idea to the next level. We haven’t seen something this ambitious since we were all talking about cloud gaming, but at least this time the games can be hosted on our own hardware.

Not Can It Run DOOM, But Can DOOM Run It?

December 25, 2022 by 15 Comments

It’s the standard test for a hardware hack, half serious half in jest, “Can it run DOOM?”. The iconic early-90s shooter from id software has made an appearance on everything from toothbrushes to LEGO bricks, but nobody has yet posed the opposite question: Can DOOM run it?“. It’s one answered by [Danny Spencer], who has proved that it’s possible to perform computational tasks in the game by producing a working adding machine in a DOOM level.

If you’re familiar with the folks who build working computers within Minecraft, this is in a similar vein. Game elements are used to create logic elements, and from there more complex systems can be assembled. DOOM doesn’t have the in-game logic that Minecraft has, but by clever combination of monster behaviour with in-game actions involving rooms, buttons, and doors, it’s possible to create the simplest of building blocks, the NAND gate.

The video below the break shows the adder in action, first in operation (we like the monster-driven display!), and then a tour of the logic area with its rooms full of computational monsters. It’s important to note that this isn’t a computer, he hasn’t proved it as Turing complete, and that the maximum size of a DOOM level whatever it is will impose an upper limit on what can be done. But it does show that in theory at least a computer can be made in DOOM, and we’re sure people will continue this work.
