Tiny N64 Controller Comes With Hand-cramp Guarantee

April 27, 2012 by Mike Szczys 7 Comments

Just looking at this little thing makes our hands ache. But [Kirren] did do a great job of building an N64 controller inside a tiny project box. It’s not a mod, but a ground-up build based on a PIC 16F628 microcontroller.

It has most of the buttons found on a standard controller, and he assures us that you can play most games without missing the ones that didn’t make it into the design. You can just make out the analog stick to the left, but that silver ring on the right is actually a 4-direction tactile switch which stands in for the C buttons. He’s also included Start, A, B, R, and Z.

The link above goes to his Wiki, and there are more than enough details if you’re interested in doing this yourself or just understanding how everything works. Check out his writeup on the protocol, and you can even get a copy of his code. There’s also a video demo after the break which shows [Kirren] playing some Bond with the controller.

Miniaturized N64 Controller Fits The Tiniest Of Hands

n64-controller-mod

The controllers that came with the Nintendo 64 don’t exactly measure up to the “Duke” of Xbox fame, but they’re not the smallest in the world either. Made by Bacteria forum member [Bungle] says that his girlfriend has incredibly tiny hands, so he thought he might try trimming some of the fat from an N64 controller by cramming its components into an N64 cartridge.

He tore down a 3rd-party N64 controller, tossing out the D-Pad, plug, and rumble motor, retaining all of the other buttons. After gutting the game cartridge, he heated the back side under a lamp and stretched the plastic over a roll of electrical tape to make room for the N64’s trademark “Z” button. Having only removed the rumble motor due to size constraints, he found a suitable replacement at Radio Shack, which fills in for the original nicely.

After a good amount of careful trimming, wiring, and mounting, he came up with the little gem you see above. We’re sure [Bungle’s] girlfriend is pleased with his work, and he seems happy with how it came out as well.

Continue reading to see a short video showing off [Bungle’s] latest creation.

A Locking Chest With A Musical Key

music-detecting-box

[Basil Shikin] was thinking about different types of locks, and was trying to come up with a locking solution that he had yet to see. It dawned on him that he had never come across a lock triggered by music, so he set off to construct one of his own.

He ordered a wooden chest online, then proceeded to piece together the electronics required for the locking mechanism as well as the music detecting logic. Using an Atmega328P paired with an electret mic, his system listens for a particular tune (the Prelude of Light from the Ocarina of Time) to be played , which triggers a tiny servo to undo the latch. To do this, he implemented a version of the Goertzel Algorithm on the Arduino, allowing him to accurately detect the magical tune by frequency, regardless of what instrument it is played on.

Be sure to check out the video below to see his musical lock in action.

Overclocking A Starfox Game Cartridge

January 31, 2012 by Mike Szczys 22 Comments

Some of our younger readers will never have experienced this before, but back in the day your video games would slow way down if there were too many moving objects on the screen. The original Castlevania comes to mind, but many will remember the problem while playing the fantastically three-dimensional Super Nintendo game Starfox. [Drakon] isn’t putting up with that hardware shortfall any longer, he hacked this cartridge to run at 42 MHz, twice as fast as the design spec.

We only occasionally look in on the cart hacking scene so it was news to us that three different versions of a pin compatible chip were used in this hardware. The first two suffer from the slowdown problem, but the final revision (SuperFX GSU 2) doesn’t. It can also be overclocked as high as 48 MHz but because of the video frame rate you won’t see added improvement with the extra 6 MHz.

[Drakon] used a Doom cartridge as a guinea pig because it offers the most RAM, and set to work rerouting the traces for the ROM chip to an EEPROM so that the hardware can be used with different games. He also took this opportunity to patch in the faster clock signal.

NES Controller Uses Capacitive Touch Instead Of Buttons

January 19, 2012 by Mike Szczys 29 Comments

Here’s one way to really keep the component count low. [David] developed an NES controller that doesn’t use any buttons. The copper clad has been milled to provide a pad which registers a button push based on capacitance. The board has a SIL header at the top, making it easy to plug into the Arduino board that reads the inputs.

[David] had trouble getting the Arduino pin read functions to respond fast enough for he NES console’s expectations. He ended up using commands to access the ATmega’s peripherals directly in order to achieve the target timing. Speaking of, he did his own sniffing of the communication scheme using a logic analyzer. The results of that work, as well as the board files and code are available at the site linked above. And there’s a demo of the controller used to play Super Mario Bros. in the clip after the break.

This is actually a tangential project using a PCB mill which he’s developing through Kickstarter. This certainly shows that the mills works as designed. Continue reading “NES Controller Uses Capacitive Touch Instead Of Buttons” →

Knockoff Game Controller Makes A Fine Remote Shutter Release

December 29, 2011 by Mike Nathan 3 Comments

remote-shutter-release

[Duncan Murdock] received a Canon DSLR camera for Christmas and wanted a remote shutter release to go along with it. Since nary a store was open on Christmas, he was pretty much out of luck. Scrounging around in his parts drawer, he found all sorts of goodies waiting to be reused, including a knockoff Wii nunchuck.

He pulled the original cable from the nunchuck and replaced it with an old telephone wire, attaching a 2.5mm plug to the end. The plug goes directly into his camera’s control port, allowing him to trigger the auto focus and shutter mechanisms with the push of a button.

We like the idea of a junk controller being recycled for use in a camera, though we think it has far more potential than being used as a simple wired trigger. If both the nunchuck and camera were fitted with some sort of wireless interface (Bluetooth, IR, etc), we think it would make a great addition to any hobby photographer’s kit.

Funtendo Connects All Your Nintendo Controllers To A PC

November 30, 2011 by Brian Benchoff 11 Comments

For those of us who can’t be bothered to dig out or N64 whenever we want to play Ocarina of Time or our NES whenever we get the urge to play Battletoads, emulators are a godsend. There is a problem, though. A keyboard doesn’t provide the right experience as a the classic NES ‘brick’ or the N64 tritopus controllers. Enter the Funtendo, a breakout box that converts all your well-loved controllers to USB.

The Funtendo uses the Gadget Gangster Propeller Platform with a terminal block module. Putting together the electronics is fairly easy; just strip the ends of the controllers and screw them down to the terminal blocks. N64, NES and Wii Classic Controllers are supported by the Funtendo. Going for the Classic Controller over a Super Nintendo controller reduces the complexity of the build. The Classic Controller can play SNES games and uses an I2C bus, making it easier to wire.

For interfacing the controllers to the computer, the Parallax Propeller Tool, Parallax serial terminal, and PPJoy convert button mashing into readable buttons for the emulator. The build may take more time than pulling an NES out of the attic, but even with a large project box it takes up much less space.

Check out the demo of the Funtendo after the break.
