DrunkenNES Makes A Game Out Of Getting Hammered

While handheld breathalyzers are pretty novel to have around while drinking with friends, there’s nothing exciting about a $50 off the shelf unit. If you really want to grab people’s attention, you have to get creative and built something like [Batsly Adams] and his friends did.

One evening, he was casually drinking with some friends and playing around with an electronic alcohol sensor. They quickly put together a NES ROM that would play sounds, changing the pitch depending on how much alcohol the sensor detected. It quickly became apparent to them that a full-fledged breathalyzer video game was in order. In no time, he and his friends had compiled graphics, a soundtrack, and the code to drive their game, DrunkenNES.

To play the game, each player must blow into a gutted NES cartridge that has been fitted with the alcohol sensor. The Nintendo computes the player’s BAC, reporting how intoxicated they are using simple graphics and cheesy animal puns. We don’t know when the code and schematics will be made available, but when they are, you can guarantee we will be building one for “research” purposes to pair with our Power Hour shot glass.

Walking Motion Analysis Using Wii Remotes

March 1, 2011 by Mike Szczys 10 Comments

WiiGait is not a political scandal, it’s a project that records motion data while walking. [Bilal Chishti] and [Zassa Kavuma] are strapping a Wii remote onto each leg and recording the sensor data while making video of the walker at the same time. The two are using an Ubuntu box to pull the sensor data from the Bluetooth-enabled devices and utilizing its built-in webcam for the video. They graph the data for each axis and we’re sure that syncing up data anomalies with the video is just a matter of matching timestamps.

So what good is this? The creators are keeping us in the dark about an end-goal for collected data; this may just be for the experience of using the hardware. But we could see it having uses in making distance runners more efficient, or teaching that bipedal robot how to balance.

NES Game Pad Wireless Light Commander

Annoyed that the new lights he bought for his apartment lacked power switches, Instructables user [p.arry.drew] decided to install a pair of wireless light switches. Not content to use the remotes separately, he decided to see if he could cram them both into an old NES controller, making for a nice all-in-one wireless light commander.

He disassembled the light switch remotes, cutting off a bit of the battery contacts to ensure they fit in the game pad. He then pulled apart his NES controller, removing the cord and adding some foam padding to ensure that the buttons fully contacted the wireless switches when pressed. A few bits of wooden dowel were added to keep everything in place, then the controller was reassembled.

His creation makes for a very convenient method of controlling several light switches from once source, plus the packaging is pretty handsome as well. These remote light switching solutions seem to be all the rage lately, so keep them coming!

Read on for a quick video of his remote light switches in action.

Bluetooth-enabled Wii Nunchuck

February 18, 2011 by Mike Nathan 16 Comments

The wireless controller for the Nintendo Wii has been used in many a hack due to its simple to use Bluetooth interface. The nunchuck portion of the controller however, has always required a physical tether to the wireless controller, or an aftermarket wireless dongle. [Rousselmanu] is looking to change that with his Bluetooth-enabled wireless Wii nunchuck. He is able to retrieve a slew of data from the nunchuck, including information from all of the accelerometers, buttons, as well as the joystick. The data is read into a PIC MCU and relayed via serial to a Bluetooth module he purchased online.

The Bluetooth module looks fairly easy to interface in Linux, and [Rousselmanu] has a video showing off how well the nunchuck can be used to interact with 3D models. He admits that the controller is a bit ugly at the moment as all the components don’t quite fit so well, but future revisions will surely remedy that.

NES Paul Game Controller

[NeoTechni] wrote in to share the new game peripheral she built, dubbed the NES Paul. The ultimate goal of the project was to build a NES-styled controller for an upcoming game she is working on, tentatively titled 8-bit Hero. The guitar is constructed primarily from wood, as well as some scrounged bits she had around the house. An Xbox 360 controller was dismantled and wired to provide input for the guitar’s buttons and D-Pad. Even the Xbox controller’s rumble packs were used in order to provide visual feedback of missed notes via LED tuning pegs on the guitar’s headstock.

The writeup is broken into several pieces as it was put together in a handful of Google Buzz posts, but it is still relatively easy to follow. We can’t wait to see how the project comes together once the game portion has been completed.

Recordable SNES Belt Buckle

[Andrew] recently offered to help out a friend who was looking to get her husband a SNES controller belt buckle. Rather than simply slap one together, he decided that it would be far cooler if the belt buckle played audio as well. He gutted a broken SNES controller, removing most everything inside, leaving just the buttons and a few wires.

To allow for the belt buckle to record sounds, he pulled apart a recordable balloon that would play a 10-second audio clip when shaken. He moved around a few wires, allowing for the audio board to be triggered by a button press rather than motion. Once that was done, he went about fitting it into the SNES controller, drilling speaker and microphone holes in the process. With the electronics components all set, he reassembled the controller shell and mounted it to an old belt buckle he had sitting around.

The final product looks extremely fun, and would make any die hard Nintendo fan’s day.

NintendOscope

[Craig] has taken his gameboy hackery to the next step, using an oscilloscope as an external display. Back in November of 2010 [Craig] showed us how to extract the video data from a classic gameboy’s screen, armed with that information, and a pretty powerful XMega128A1 controller it seems straightforward to process that data and output it onto a oscilloscope that is in XY(z) mode, especially since he has done all of the hard work for us.

Scopes that feature XY mode typically have a Z input on the back, X controls where the beam is positioned from left to right, Y controls the beam from top to bottom, and Z controls the intensity of the beam. By sweeping the X and Y to act as lines, and Z to control the shade of the beam, its fairly easy to reuse your typically vector display as a raster display similar to televisions or computer monitors (as long as you have your math and timing right), making scopes very useful as output displays for devices like the gameboy, which do not have “standards” friendly display systems.

Join us after the break for a short video, and also check out the scope terminal, or the VGA-to Sope converter for more examples of how to use your oscilloscope as a raster display.
