Wii U RetroPie Console Looks Gorgeous

November 1, 2016 by James Hobson 8 Comments

What to do with your broken gaming consoles? Gut it and turn it into a different gaming console! Sudomod forum user [banjokazooie] has concocted his own RetroPie console from the husk of a WiiU controller — an ingenious demonstration of how one can recycle hardware to a perfectly suited purpose.

[banjokazooie] actually used an original shell for this build, but if you happen to have a broken controller around — or know someone who does — this is a great use for it. A Raspberry Pi 3 is the brains of this operation (not counting [banjokazooie]), and it features a 6.5″ HDMI display, a Teensy 2.0 setup for the inputs, a headphone jack with automatic speaker disconnection, dual 3400 mAh batteries, an external SD card slot, and a lot of hard work on the power supply circuit — although [banjokazooie] reports that the hardest part was cutting to size a custom PCB to mount it all on. The original plan was to see if the idea was possible, and after a three month effort, it appears to work beautifully.

Become Very Unpopular Very Fast With This DIY EMP Generator

October 12, 2016 by Gerrit Coetzee 141 Comments

Taking a break from his book, “How to Gain Enemies and Encourage Hostility,” [FPS Weapons] shows us how to build our own handheld EMP generator which can be used to generate immediate dislike from anyone working on something electronic at the hackerspace.

The device is pretty simple. A DC source, in this case an 18650 lithium battery cell, sends power to an “Ultra High Voltage 1000kV Ignition Coil” (as the eBay listing calls it), when a button is pressed. A spark gap is used to dump a large amount of magic pixies into the coil all at once, which generates a strong enough magnetic pulse to induce an unexpected voltage inside of a piece of digital electronics. This usually manages to fire a reset pin or something equivalent, disrupting the device’s normal operation.

While you’re not likely to actually damage anything in a dramatic way with this little EMP, it can still interrupt an important memory write or radio signal and damage it that way. It’s a great way to get the absolute shock of your life if you’re not careful. Either from the HVDC converter or the FCC fines. Video after the break.

Beware Of Tall Grass: Pokemon Go On The Gameboy Pocket

July 25, 2016 by Gerrit Coetzee 13 Comments

[Pepijn de Vos] was excited to interact with the world’s most popular augmented reality pedometer, Pokemon Go, and was extremely disappointed to find that his Blackberry couldn’t run it. Still, as far as he could tell from behind his wall of obsolete technology, Pokemon Go is all about walking distractedly, being suspicious, and occasionally catching a Pokemon. That should be possible.

Not a stranger to hacking Pokemon on the Gameboy, [Pepijn] put together a plan. Using his TCPoke module, he took it a step further. Rather than just emulating the original gameboy trade signals over the internet, he hacked a Pokemon Red ROM with some custom Z80 assembly to add some features to the Cable Club in the game.

After some waiting for the delivery man to bring a flashable cartridge and along with some Arduino code, he could now translate the steps he took in the game to his steps in the real world. Well, mostly. He could pick the location where he would like to catch a Pokemon. The character stands there. Somewhere around 100m the game will trigger a random pokemon battle.

[Pepijn] is now no longer a social outcast, as you can see in the video after the break. On a simple trip to the grocery store he caught two Pokemon!

Case Modding The Old School Way

July 17, 2016 by Brian Benchoff 11 Comments

Since the release of the Raspberry Pi, the hallowed tradition of taking game consoles, ripping all the plastic off, and stuffing the components into nice, handheld form factors has fallen off the wayside. That doesn’t mean people have stopped doing it, as [Akira]’s masterful handiwork shows us.

This casemod began with a Nintendo GameCube ASCII keyboard controller, a slightly rare GameCube controller that features a full keyboard smack dab in the middle. While this keyboard controller was great for Phantasy Star Online and throwing at the TV after losing Smash, the uniqueness of this controller has outshadowed its usefulness. [Akira] began his build by ripping out the keyboard and installing a 7 inch LCD. It fits well, and makes for a very unique GameCube case mod.

The rest of the build is about what you would expect – the motherboard for a PAL GameCube is stuffed inside, a quartet of 18650 batteries provide the power, and the usual mods – a memory card is soldered to the motherboard and an SD Gecko allows homebrew games and emulators to be played.

The completed project is painted with the same theme as [Samus Arans]’ Varia suit, making this a one of a kind casemod that actually looks really, really good.

Cheating At Video Games: Arduino Edition

June 22, 2016 by Elliot Williams 9 Comments

[Javier] has put in his time playing Final Fantasy X. In the game, there’s a challenge where you have to dodge 200 consecutive lightning strikes by pressing a button at just the right time. [Javier] did this once, but when he bought a new PS Vita handheld, he wanted the reward but couldn’t bear the drudgery of pressing X when the screen lights up 200 times.

So he did what anyone would do: hooked up a light-dependent resistor to an Arduino and rubber-banded a servo to press the X button for him. It’s a simple circuit and a beautiful quick hack, all the more so because it probably only took him a half hour or so to whip up. And that’s a half hour better spent than dodging lightning strikes. According to his screen-shot, he didn’t stop at 200 dodges, though. He racked up 1,568 dodges, with a longest streak of 1,066. You can watch a video on his blog and pull the code out of his GitHub.

Why do this? Because that’s what simple computers are for. We hate these silly jumping mini-games with a passion, so we applaud anyone who cheats their way around them. And while not as hilarious as this machine that cheats at Piano Tiles, [Javier]’s hack gets the job done. What other epic video game cheats are we missing?

Modifying A Raspberry Pi 2 To Fit In Small Places

April 22, 2016 by James Hobson 30 Comments

Still can’t get your hands on a Pi Zero? We know. Why not de-solder a few headers from a Raspberry Pi 2 to fit in your next project instead? Using a pair of 2.5″ HDD enclosures, [nodenet] made a mini linux laptop using the Raspberry Pi 2 — It even has a touch screen, and features a 1000mAh battery!

All in all it cost him about $120 for all the components, but before you rush out to make your own, you will need pretty good skills with a soldering iron to successfully downsize your Raspberry Pi 2. The modifications require removing both USB ports, the Ethernet plug, the GPIO pins, the HDMI port, the A/V jack and the camera connectors.

He used a combination of a mini hacksaw, and a soldering iron to remove all the components — what you’re left with his a business card sized computer — but the real fun part is re-attaching all the components with leads.

Tiny ATtiny85 Game Console

April 10, 2016 by Jenny List 10 Comments

[Ilya Titov] has made a game console. Not just any game console, but an extremely small ATtiny85-based console suitable for putting on a key ring and assembled into a very professional product with PCB and 3D printed case. This is a project that has been on the go since 2014, but the most recent update is a new version designed for tighter and more easy assembly.

All construction is through-hole rather than SMD, and aside from the ATtiny85 the console uses an OLED screen, piezo buzzer, tactile switches and a handful of passive components. Power comes from a single CR2032 coin cell which sits under the screen. Best of all the PCB design is available as a PDF and the 3D printed case can be found on Thingiverse.

There are two games for the console, as well as the Breakout clone whose code is in the 2014 piece linked above he’s written UFO Escape, an obstacle-avoiding side-scroller. You’ll have to burn both game and 8MHz internal clock bootloader to the ATtiny85 yourself. There are no cartridges with this console, though if the processor sits in a DIP socket the game can be changed over simply by swapping processors programmed with the appropriate game.

He’s produced a full assembly video with some UFO Escape gameplay thrown in, shown here below the break.
