Portable NES Console Gets It Oh So Right

March 24, 2011 by 16 Comments

nes_portable

[Doug] over at the moddedbybacteria forums has been working hard on a fantastic looking portable NES console and wrote in to let us know it was complete.

The console started as a simple idea to use a Nintendo on a chip (NOAC) board in order to create a portable console that played original NES cartridges. Once a plastic case and some batteries were sourced, along with the NOAC board, the project was well on its way.

[Doug] eventually decided that he would rather use a real Nintendo motherboard in the project, so the NOAC was scrapped…temporarily. He accidentally fried the Nintendo board, so it was back to the NOAC, but with upgraded wiring to take care of some interference problems he was having earlier in the build. An original NES controller was disassembled for use in the console, which gives the portable an authentic feel. Getting the case to look just right was a long process, but we think he did a great job with it.

If you want to take a look at his entire build log, be aware that it is 23 pages long. If you’re impatient and want to jump straight to the unveiling, that happens on page 22.

Keep reading to see a pair of videos [Doug] put together both during the production and after his build was completed.

Real Life Super Mario Coin Block

March 23, 2011 by 15 Comments

mario_coin_block

Instructables user [Bruno] recently constructed a fun little toy that brings a bit of the Mario nostalgia out of the video game universe and into ours. His Super Mario coin block is instantly recognizable from the first Mario game and performs just as you would expect it to. Punching or tapping the bottom of the block releases coins one at a time, complete with sounds straight from the game.

The coin block is constructed from thick cardboard and wrapped in color mock ups of the in-game block. Inside, a spring-loaded tube of coins is placed above a launch arm which is also connected to a spring. A servo actuated arm pulls the launch arm down, dropping a coin from its tube on to the launch arm which is then flung from the top of the box once the servo arm rotates far enough. When this occurs, the built-in MP3 player is triggered to play the “coin sound” from the game. A 555 timer is used to ensure the servo actuated arm rotates once per activation, and a LM386-based amplifier is used to increase the output volume of the MP3 player, both of which operate using rechargeable batteries.

Be sure to check out some of the inner workings as well as the final product in the videos embedded below.

N64Boy Advance

March 17, 2011 by 11 Comments

[Hailrazer] found a Game Boy Advance carrying case in his closet and thought he could pull off an N64Boy Advance in a few weekends. Despite the fast build time, [Hailrazer] built something that wouldn’t look out of place sitting on a shelf at a toy store.

This isn’t the first time we have covered an N64 Advance portable gaming system that uses a GBA carrying case, but this hack keeps the original styling of the Game Boy Advance without all the epoxy, bondo and sanding. Inside is a 4.3″ screen, GameCube joystick, N64 expansion pack, and enough Li-ion to get 5-6 hours of play time. The build doesn’t include a D-pad because [Hailrazer] doesn’t use that while playing. It also doesn’t have controller or A/V ports, because he doesn’t, “want to sit around with friends playing N64 on a 4.3″ screen.” A very pragmatic build, indeed.

We love seeing people re-purpose odd bits of plastic they have lying around, so we’re wondering when someone with an Original Game Boy Carrying Case will build an NESBoy. Video after the jump.

RoboTouch Adds Physical Game Controls To The IPad

[ProtoDojo] wanted to play a racing game on his iPad, but he was not a big fan of using the touch interface for this particular title. Instead, he put together a pretty neat little hack that allows him to play games on his iPad using an old NES controller.

He built a set of custom conductive arms which he mounted on three micro servos. The servos were attached to the iPad screen using small suction cups in the locations where it expects to receive button presses. They are also wired to an Arduino that interprets button presses from the attached NES controller. When the Arduino senses that the D-pad or buttons have been pressed, it triggers the servos, which in turn press the virtual buttons on the screen.

In the video below, you can see that after adjusting the servo positions, the setup seems to work pretty well. You might expect to see some sort of lag with a setup like this, but we didn’t notice any. The [ProtoDojo] web site is currently down due to heavy traffic, but you should be able to find some more build details there, once it becomes functional again.

Wiimote-based Whiteboard Lets You Write On Any Surface

March 7, 2011 by 15 Comments

The Wiimote is a fantastic tool for hackers, given their affordability and how easy they are to work with. [Gareth] had a “eureka” moment while working on another Wiimote-based project, and with some alterations, converted it into an electronic whiteboard.

The whiteboard was built using the IR sensor he extracted from a Wiimote, which is wired to an EasyProp board to process the input. The Wiimote is aimed at a LCD screen, which can be “drawn” upon using a light pen he constructed from an IR led and a few batteries. Any movement of the pen is tracked by the Wiimote’s IR sensor and converted to an XY coordinate, which is then painted on the screen. The sensor has the ability to track up to four points at a time, so you can theoretically use up to four pens simultaneously.

[Gareth] points out that the sensor is not limited to tracking small displays, as the white board can be easily scaled up in size using any kind of rear projection device.

DrunkenNES Makes A Game Out Of Getting Hammered

March 2, 2011 by 5 Comments

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 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.
