[Samuel] is working on one of the most important electronics projects of our generation. He’s building a device for the Game Boy that will allow Pokemon trades between generation II and III. Yes, This means bringing your Charmander from Pokemon Red to your team in Pokemon Ruby, Sapphire, or Emerald. and finally completing the National Dex you’ve been working on for 20 years. Before he gets to designing this system, he first needs to listen in on the Game Boy Link Cable, and that means creating a breakout board.
The Game Boy Link Cable – sometimes inaccurately referred to as the Zelda cable – is a special proprietary connector. The design is well documented, but unlike the Wii Nunchuck controller, there’s no readily available breakout board available for this piece of obsolete technology.
Together with a his friend [David], [Samuel] loaded up a copy of Eagle and designed a board that will fit on a small piece of copper clad FR4. This design was then sent over to a small CNC mill, The traces were machined away, and a sextet of pins were soldered into the holes.
With a breakout board for the Game Boy Link Cable, [Samuel] now has a great platform for peering into the strange and magical world of Pokemon. He’ll be using a Teensy microcontroller for his trading device, and with several similar projects already completed by others around the Internet, the potential for a Gen II to Gen III Pokemon trader is palpable.
If you grew up playing Pokemon Red or Blue, you might have moved far away from your childhood friends by now. If you’re still playing Pokemon Red or Blue, you can now literally reconnect with these friends using [Pepijn]’s new and improved Game Boy link that lets players trade Pokemon over the internet.
Based on [Pepijn]’s previous work building an Arduino-based Pokemon storage system (which was inspired by a separate project that was able to spoof trades), the device allows a Game Boy (including Pocket, Color, and Advance versions) to connect to the Internet via a Teensy shield. The online waiting room software is called TCPoke which facilitates the Internetting of the Game Boys. From there, all you have to do is connect via the project’s wiki!
The TCPoke software is available on the project’s site. Also, be sure to check out the video below which shows a demonstration of how the software works. There is noticeable delay compared to a direct link between Game Boys, but it functions very well. We didn’t see this link system work for a battle, but it would be interesting to see if it is possible. If so, you might never have to go to a Pokemon League meeting again!

Pokemon is a great game by itself, but when you realize that not all of the ‘mon are available in one game, trading is required for completion, and some pokemon aren’t available without either hacking or going to a Toys ‘R Us in 1997, you start to see how insidious this game can be. Figuring he could finally complete the game with an Arduino, [Pepijn] decided to build a pokemon storage system.
This build was inspired by an earlier post that also spoofed trades. Instead of building this project around a high-power micro, [Pepijn] decided to use an Arduino. The protocol Game Boys use to communicate with each other is extremely well documented, although that’s only half the battle. Each game using the link cable used specialized data structures for transfer, and after grepping through a disassembled Pokemon ROM, [Pepijn] figured out how everything worked.
The completed hardware keeps one Pokemon in the EEPROM of an Arduino. It’s not very fast if you want to catch all 151 Pokemon in the Gen 1 games, but any way you look at it, you’re going to be catching a lot of Magikarp anyway.
Misumi is doing something pretty interesting with their huge catalog of aluminum extrusions, rods, bolts, and nuts. They’re putting up BOMs for 3D printers. If you’ve ever built a printer with instructions you’ve somehow found on the RepRap wiki, you know how much of a pain it is to go through McMaster or Misumi to find the right parts. Right now they have three builds, one with linear guides, one with a linear shaft, and one with V-wheels.
So you’re finally looking at those fancy SLA or powder printers. If you’re printing an objet d’arte like the Stanford bunny or the Utah teapot and don’t want to waste material, you’re obviously going to print a thin shell of material. That thin shell isn’t very strong, so how do you infill it? Spheres, of course. By importing an object into Meshmixer, you can build a 3D honeycomb inside a printed object. Just be sure to put a hole in the bottom to let the extra resin or powder out.
Remember that episode of The Simpsons where Homer invented an automatic hammer? It’s been reinvented using a custom aluminum linkage, a freaking huge battery, and a solenoid. Next up is the makeup shotgun, and a reclining toilet.
[Jan] built a digitally controlled analog synth. We’ve seen a few of his
FM synths VA synths built from an LPC-810 ARM chip before, but this is the first one that could reasonably be called an analog synth. He’s using a digital filter based on the Cypress PSoC-4.
The hip thing to do with 3D printers is low-poly Pokemon. I don’t know how it started, it’s just what the kids are doing these days. Those of us who were around for Gen 1 the first time it was released should notice a huge oversight by the entire 3D printing and Pokemon communities when it comes to low-poly Pokemon. I have corrected this oversight. I’ll work on a pure OpenSCAD model (thus ‘made completely out of programming code’) when I’m sufficiently bored.
*cough**bullshit* A camera that can see through walls *cough**bullshit* Seriously, what do you make of this?
Early this year, Twitch Plays Pokemon, a webstream of tens of thousands of people playing the same game of Pokemon via web chat. It was certainly an interesting sociological phenomenon, but as in any system where thousands of people try to do a single thing, progress was exceedingly slow at points. This was compounded by the fact the Twitch stream delayed the chat by about 30 seconds.
At the time, there was some talk about setting up an alternative to the emulator-based Twitch stream. Ideas were floated, but until now, no one has yet come up with a workable solution. Now we have Pokáde: real Pokemon games (Red and Blue) running on real hardware (two Super Game Boys, two super Nintendos, and two Game Genies), streamed live to the Internet with an IRC-like chat function.
Simply for the ease of capturing the video of the stream, [Johannes], the guy behind all of this, is using a pair of Super Nintendos and Super Game Boys connected to USB video capture dongles. The Super Game Boys are modded to enable trading between the Red and Blue versions of the game, and controls are handled with a USB connection to the PC running the server.
Anyone can play the game, simply by going to the Pokáde Chat, entering the chat, and clicking on random buttons on the brick Game Boy GUI. The game ROMs have been slightly modified to disable the option of starting a new game, but this is still the classic Twitch Plays Pokemon experience: people all around the globe mashing buttons and creating a religion around a fossil pokemon.
Check out this Pokemon Yellow cartridge for Super Nintendo. Wait, what? That is a Game Boy game! Well there is a Super Gameboy cartridge that lets you play them on SNES. This mashes the guts of the two into a custom-decorated SNES cart. Now if you’re more interested in the guts of that Super Game Boy cartridge you’ll want to check out this classic hack which dumped the ROM from it. [Thanks Nick]
Here are a couple of interesting things from our friends over at Adafruit. First off, they have a high-res gallery of the Raspberry Pi compute module and carrier boards which we heard about earlier in the week. Also, the latest Collin’s Lab has a great video on soldering. We especially appreciated the discussion of soldering iron tips and their effect on heat transfer.
[Marius] got tired of the static shock from the office coat rack. You know, like the scene straight out of Office Space? But he didn’t disassemble the infrastructure to solve the issue. Instead he connected it directly to ground. Just make sure you stick the wire in the correct hole!
It’s as if Hackaday is on a quest for the most perfect DIY cyclonic separator. Here’s the latest offering which you can cut out from sheet stock by hand. It’s the alternative for those of us without access to a 3D printer.
If you think it’s too difficult to build what we refer to as a Daft Punk table you need to check out what [Dan] pulled off. He proves that your LED matrix coffee table project doesn’t have to take up a ton of time or cost an exorbitant amount of cash.
We should have mentioned this to you before the weekend so you’d have something to watch: you can now download BBS: The Documentary from the Internet Archive. We’ve watched the entire thing and it’s fantastic. If you know what a dial-up modem handshake sounds like, you’re going to be awash in nostalgia. If you don’t know the delight of those sounds you need to watch this and see how things used to be back in the day when connecting your computer to a network definitely wasn’t what the cool kids were doing. [Thanks Larry]
Gameplay is simple – users type their command (Up, Down, A, B) into their IRC or web client. In the original configuration, commands were processed in the order they arrived at the game. The system worked until the whole thing went viral. With thousands of people entering commands at any given time, poor “RED” would often be found spinning in place, or doing other odd things. The effect is so compelling that even [Randal Munroe] has written an XKCD entry about it. To help the players get through some of the tricky parts of the game, [TPP’s creator] added a game mode selection. Users can play in “Democracy” where the system takes votes for several seconds, then issues the highest voted command. The original anything goes game mode was renamed “Anarchy”. Switching from one mode to the other is determined by the users themselves in real-time.
[Devon], one of our readers, has been busy as well. He’s written up a tutorial on turning a Raspberry Pi into a dedicated TPP viewer. We’d love to see a TPP battlestation – a Game Boy modified to display TPP, as well as send commands to the IRC servers when buttons are pressed. Who will be the first reader to knock that hack out?
