If you’ve ever wanted to take a dive into and visualize a game’s code, this could be a seminal example in a literal sense. After twenty-one months of effort, the entire Pokemon Red game is now playable inside Minecraft.
[Mr. Squishy] is the mad genius behind this project, laboriously re-coding the game literally block by block. A texture pack is needed for the specific sprites, but otherwise it is playable without mods. It’s not immediately apparent when loading in to the level, but chip your way through the floor of the stadium and you are confronted by something awe-inspiring: sprawling constructions, like great soaring cliffs, comprising approximately 357,000 command blocks — equating to the same in lines of code. Every animation, tracked stat, attack and their effects, the various pokemon and their properties, and so on are rendered in the game’s physical space for you to wander through.
Beneath that are levels of maps, positional data, properties of those areas, NPCs, and a clever glitch that [Mr. Squishy] used to keep everything loaded at once.

If you’ve played even just a few minutes of Minecraft, you know what a creeper is. For those not familiar with the wildly popular sandbox game, a creeper is a monster that creeps along silently until it’s close to a player, whereupon it self-destructs by exploding. Sometimes it kills the player outright, and other times the explosion blows them into lava or off a cliff, or off a cliff and then into lava. Creepers have no friends.
But now there’s a way to avoid creeper attacks, or at least get a little heads up that these green nasties are lurking about. With [John Allwine]’s creeper detector, Minecraft players can get a real-world indicator of the current in-game creeper threat. The hardware end is simple enough — it’s just a SparkFun RedBoard and a small strip of Neopixels in a laser-cut plywood case. The LEDs lie behind a piece of etched acrylic to diffuse their glow — extra points for the creeper pattern in the lens. The detector talks over USB to a Minecraft mod that [John] wrote to interface the game with the real world. The closer a creeper gets to the player, the brighter the light. — and when it flashes, watch out. See it in action in the video below, if you can stomach watching someone dig straight down. Never dig straight down.
If interfacing the Minecraft world and the real world sounds familiar, maybe it’s because we featured [John]’s SerialCraft mod a while back and admired the potential for using Minecraft as a gateway for getting kids into hardware hacking. We agree that this is a great project to work on with kids, but we may just order the parts to do it for our own Minecraft world. Creeper hate isn’t just for kids.

I’ve got virtual circuits on the mind lately. There are a myriad of tools out there that I could pick up to satisfy this compulsion. But the one I’m reaching for is Minecraft. I know what you’re thinking… a lot of people think Minecraft is getting long in the tooth. But chances are you never tried some of the really incredible things Minecraft can do when it comes to understanding logic structures. This goes way beyond simple circuits and easily hops back and forth over the divide between hardware logic and software logic.

Doom is now running on the ESP32. This is some work from [Sprite_tm], and the last we heard about Doom on the ESP32 is that there was a silicon bug or something. Now we’re knee deep in the dead on a tiny WiFi and Bluetooth-enabled microcontroller.
Loading animations have a long and storied history. What originally began as an hourglass quickly turned into a hand counting to five and progress bars. There were clocks, the Great Beach Ball of Death, and now loading animations are everywhere. However, the loading animation has still not been perfected — until now, that is. This is a fidget spinner loading animation. It’s beautiful.
Just a quick reminder that a Minecraft scholarship exists. Yeah, I know what you’re thinking, but there is a scholarship from the Klingon Language Institute for studying any language, and last year’s winner built a redstone computer from scratch,
[8bit generation] recently released a documentary, about the rise of Atari. Easy to Learn, Hard to Master is about the rise of Atari under [Nolan Bushnell]. Now [8bit generation] is working on a new documentary: Firing Steve Jobs. The [Steve Jobs] story is fascinating, and no matter what you think of him, he probably knew what he was doing.
Want to build and sell some hardware? Over on Tindie, we’re taking a look at some of the most successful designers of custom crafted hardware. This time it’s [Albertas Mickėnas] of Catnip Electronics who has sold five thousand soil moisture sensors.
You can just go out and buy a CNC machine, but that doesn’t quite underscore the difficulty in getting a CNC machine running. Our ‘ol pal [Jeremy] recently picked up a Romaxx CNC machine and put together a video of its commissioning. There’s a lot of work here, from building a shelf/stand for a rather beefy machine to cutting into the bed for t-tracks, and figuring out how dust collection is going to happen.
Before there was KiCad and Eagle and a ton of web-based PCB design tools, there was Autotrax. Want to know what PCB design and GUIs look like in DOS? I did a walkthrough for designing a small PCB in the DOS version of Autotrax late last year. There are thousands of designs locked up in discontinued EDA suites, and [Erich] has a way to revive them. He’s developed an Autotrax/Easytrax layout import/export plugin for pcb-nd. Now legacy Protel designs can be imported into software released in this century. This is really cool, and you can check out some screenshots here.
Apex Minecraft hosting recently held a scholarship competition. The person who sent in the best essay would win a $2,000 scholarship. The winning essay starts, “Five years ago, at age 13, I built an entire computer from scratch. Assembled from basic components: wires, torches, repeaters, pistons, and blocks, it was capable of rendering images to a display, multiplying and dividing numbers, and even calculating square roots.” I had to read it twice before it clicked that he was talking about a computer built entirely in a fictional universe.
It’s no wonder that he’s now a freshman at college, pursuing a degree in computer engineering. After reading this, I started to reminisce. The first computer I ever had access to was my mother’s laptop. It had an install of QBASIC on it, and I remember using it to make a few text based games. Later on when we got our first family computer I remember spending hours getting no better at video game programming using QBASIC.
It went on and on. I remember doing AI for video games in DarkBasic. I remember doing physics and collisions. Eventually I found my way to html, then php, to make websites about games (which are too terrible to share with you). So when the time came to program robots I was absolutely fearless. It just seemed like such a natural extension of what I already knew that it never occurred to me to be thankful for the time I spent trying to make my own simple little games until much later.
In the end I am still occasionally making little forays into game programming when I want to learn a new language or get back up to speed. It never occurred to me that perhaps this was just the way I’ve always learned a language.
Later on in the winner’s essay he goes on to describe his minecraft community. They taught new players. They taught themselves. They hung out and became friends. The writer gained a sense of self as a user of computers, a teacher of skills, a good member of a community, and a solver of problems. Unlike some of his classmates he won’t go to college and have to learn if he’s good enough. He’ll already know. All it took was a silly block based game.

With All Hallow’s Eve looming close, makers have the potential to create some amazing costumes we’ll remember for the rest of the year. If you’re a fan of the hugely addict-*cough* popular game Minecraft, perhaps you’ve considered cosplaying as your favorite character skin, but lacked the appropriate props. [Graham Kitteridge] and his friends have decided to pay homage to the game by making their own light-up Minecraft swords.
These swords use 3D-printed and laser-cut parts, designed so as to hide the electronics for the lights and range finder in the hilt. Range finder? Oh, yes, the sword uses an Arduino Uno-based board to support NewPixels LEDs and a 433Mhz radio transmitter and receiver for ranged detection of other nearby swords that — when they are detected — will trigger the sword to glow. Kind of like the sword Sting, but for friendlies. Continue reading “Minecraft Sword Lights Up When Nearby Friends”
In a clever bit of miniaturization, [JediJeremy] has nearly completed a gyro-mouse controller for a Raspberry Pi Zero! Ultimately this will be a wearable Linux-watch but along the way he had some fun with the interface.
Using the MPU6040 gyroscope/accelerometer card from a quadcopter, [JediJeremy] spent a week writing the driver to allow it to function as a mouse. Strapping an Adafruit 1.5″ PAL/NTSC LCD screen and its driver board to the Zero with rubber bands makes this one of the smallest functional computer and screen combos we’ve seen. Simply tilt the whole thing about to direct the cursor.
It presently lacks any keyboard input, and [JediJeremy] has only added a single button for clicking, but look at this thing! It’s so tiny! In his own words: “I think this is the first computer that I can accidentally spill into my coffee, rather than vice versa.”
