For every pokemon you encounter on your adventure to become the world’s greatest trainer, you have about a 1 in 8000 chance of that pokemon being ‘shiny’, or a different color than normal. Put an uncommon event in any video game, and of course a few people will take that feature to the limits of practicality: [dekuNukem] created the Poke-O-Matic, a microcontroller-powered device that breeds and captures shiny pokemon.
We’ve seen [dekuNukem]’s setup for automatically catching shiny pokemon before, but the previous version was extremely limited. It only worked with a fishing rod, so unless you want a ton of shiny Magikarp the earlier setup wasn’t extremely useful.
This version uses two microcontrollers – an Arduino Micro and a Teensy 3.0 – to greatly expand upon the previous build. Now, instead of just fishing, [dekuNukem]’s project can automatically hatch eggs, search patches of grass for shiny pokemon, and also automatically naming these new shiny pokemon and depositing them in the in-game pokemon storage system.
The new and improved version works a lot like the older fishing-only automated pokemon finder; a few wires soldered on to the button contacts control the game. The Teensy 3.0 handles the data logging of all the captured pokemon with an SD card and RTC.
What did [dekuNukem] end up with for all his effort? A lot of shiny pokemon. More than enough to build a great team made entirely out of shinies.

It’s been just a bit over a year since the Wii U was released along with the extremely impressive Wii U controller. With a D-pad, analog sticks, accelerometer, gyroscope, magnetometer, camera and 6.2 inch touchscreen, this controller is ripe for a million and one projects ranging from FPV quadcopters and robots to things we can’t even think of yet. At this year’s Chaos Communication Congress, [booto], [delroth], and [shuffle2] demonstrated how they cracked open the Wii U controller’s encryption allowing for Wii U controller ‘emulation’ and giving us full documentation on how the whole thing works.
The guys started on their reverse engineering journey by dumping all the flash chips found on the controller’s board. In those binary blobs, they found Nintendo used a truly ingenious way of obfuscating the WiFi keys used to connect the controller to the Wii: rotate left by three. To be fair to Nintendo engineers, it was secure until someone figured it out.
Connecting the controller to a PC over WiFi is only half the battle, though. Initial information from the Wii U launch suggested Nintendo used Miracast for all the I/O between the controller and the console. This isn’t the case; instead the video, audio, camera, and button input are non-standard but very simple protocols. The hardest to break into was the video display for the touchscreen, but the guys discovered it’s pretty much H.264. After getting around some Nintendo weirdness, it’s possible to display video on the controller.
The guys have put together a small, extremely alpha library that comes with all the demos, documentation, and reverse engineering information. There’s a large wish list of what this library should include, but now that the information is public, it might be the time to pick up a Wii U.
Video of the talk below, here’s the presentation slides, and a demo of emulating a Wii U game pad on a PC.

With WiFi, Wonder Trade, and new Pokemon that are freakin’ keys, you’d think the latest generation of everyone’s reason to own a Nintendo portable is where all the action is, right? Apparently not, because Pokemon Blue just became a development tool for the Game Boy.
Despite all notions of sanity, this isn’t the first time we’ve seen someone program a Game Boy from inside a first generation Pokemon game. Around this time last year, [bortreb] posted a tool assisted run that deposited and threw away in-game items to write to the Game Boy’s RAM. Using this method, [bortreb] was able to craft a chiptune version of the My Little Pony theme inside Pokemon Yellow.
A year later, [TheZZAZZGlitch] has gone above and beyond what [bortreb] did. Instead of a tool assisted run, [ZZAZZ]’s hack can be done manually on a real Game Boy. This trick works by using an underflow glitch to obtain item ‘8F’ in the player’s inventory. Here’s a great tutorial for doing that. With this 8F item, a few items can be tossed and a ‘programming’ mode is activated where code can be written to RAM by walking to an X Y position on the map, using the 8F item, and writing a program byte by byte.
The maximum amount of code that can be written to the Game Boy RAM is 254 bytes, just large enough for [TheZZAZZGlitch] to write a very, very simple version of Akranoid, Breakout, or one-player Pong. Not much, but very, very impressive.

Like all good hackers [Osgeld] makes regular appearances at the thrift store to scavenge for raw materials. This summer he was lucky enough to come across a couple of NES clone games. These are controllers that emulate the original Nintendo Entertainment System by connecting to a television using composite video. The mechanics of the controllers were pretty much shot, but he knew he could do something with the boards inside. It was a small gamble at a dollar apiece anyway.
As you can see above, he upgraded a vintage NES Advantage controller by stuffing it full of the emulator hardware. To start he disassembled the arcade-like peripheral and gave everything a thorough cleaning. Since he was going to be soldering onto the PCBs anyway he upgraded the controller by swapping out the original switches for a different set of tactile switches. The large base provided plenty of room for [Osgeld] to fit the emulator (with included ROMs) and now he’s Playing with Power.
The NES Advantage is a very nostalgic controller. Even the Ghostbusters hacked on it!
[Travis] wanted us to take a look at his N64 portable to see if it could be featured on Hackaday. By the looks of it, we’re going to say hell yeah. Everything on this portable N64, down to the buttons, is milled from aluminum. It’s an amazing build that raises the bar of what a portabalized game system can be.
Inside this anodized enclosure is the circuit board from an original N64. To cut down on the size, [Travis] milled a new heat sink for the CPU and GPU. All the games – quite possibly all the games ever released for the N64 – are stored on an SD card and accessed through an EverDrive 64. Two 5000 mAh Lipo batteries provide three hours of play time on a beautiful high-res screen.
What’s even more amazing is that [Travis] machined all the parts on an exceedingly small, manual mini-mill. Truly a portabalized console for the ages.
You can check out a gallery of pics [Travis] sent in and his demo video below.

For reddit user [the_masked_cabana], button mashing has taken on a whole new meaning. His gigantic NES controller coffee table makes it hard to punch in the Konami code without breaking a sweat.
Even before discussing the electricals, this is one impressive build. Each component was cut from multiple layers of MDF and assembled with screws, glue, and putty. Once they were sanded smooth, he used layers of carefully applied Krylon paint to achieve a plastic sheen that is remarkably faithful to its 5″ counterpart. For the more precise lettering, custom cut vinyl stickers did the trick.
Of course, looking the part is only half the battle. Tearing apart an original NES controller, he soldered wires to the button connections and ran them to eight arcade style buttons located under the replica button covers. A collection of bolts and springs keep everything aligned and produce the right kind of tactile feedback to the user. A removable cable in the back provides the connection to the console.
If a four foot NES controller isn’t practical enough for you, he also added some storage space in the base and a removable glass cover that converts the controller into a coffee table. For more details on the build, check out the reddit discussion. You can also find an eerily similar working NES controller table in this geeky coffee table roundup from five years ago.
Released 25 years ago, the Nintendo Power Pad, a plastic mat that plugged into an NES, saw very limited success despite its prevalence in basements and attics. In total, only six games for the Power Pad were released in North America, and only 13 worldwide. The guys over at cyborgDino thought they should celebrate the sliver anniversary of the Power Pad by creating its 14th game, using an Arduino and a bit of playing around in Unity 3D.
The first order of business was to read the button inputs on the Power Pad. Like all NES peripherals, the Power Pad stores the state of its buttons in a shift register that can be easily read out with an Arduino. With a bit of help from the UnoJoy library, it was a relatively simple matter to make the Power Pad work as intended.
The video game cyborgDino created is called Axis. It’s a bit like a cross between Pong and a tower defense game; plant your feet on the right buttons, and a shield pops up, protecting your square in the middle of the screen from bouncing balls. It’s the 14th game ever created for the Power Pad, so that’s got to count for something.
Video of the game below.
