Hair Thin Wires Save a 3DS from the Landfill

Broken Nintendo 3DS

[Anton] recently acquired a broken Nintendo 3DS. When the power button was pressed, the device would start booting up only to shut back down after flashing a blue light and making a popping sound. It turns out this problem is pretty common with the 3DS.

[Anton] could have tossed this device into the landfill, but where’s the fun in that?  Instead, he cracked the device open like any self-respecting hacker would. It didn’t take him long to discover two broken flex ribbon cables. [Anton] could have then searched for replacement cables, but his inner hacker told him he could repair this himself. He carefully scraped the insulation off of the broken traces and then soldered on some hair thin wires to bridge the gap.

All that was left to do was to glue the wires securely in place and feed them back through the hinges. This project is a great example of how a little determination and know-how can keep a useful device from the landfill. If you attempt this repair yourself, you may find this 3DS teardown to be a helpful reference. What devices have you been able to save from an untimely demise?

Gotta Catch ‘Em All, With An Arduino

PKMN

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.

Video below, with all the code available through a link in the description.

Finding Shiny Pokemon Automatically

pkmn

In case you’re not up to speed with the world of Pokemon, nearly every species of this game’s titular creatures have a ‘shiny’ variety – a differently colored sprite for each pokemon. As far as gameplay goes, they’re exactly the same as their non-shiny brethren, but the shiny varieties are so impossibly rare not many players have seen them. [dekuNukem] over on Youtube has come up with a great way to find these shiny Pokemon automatically with the Hackaday reader’s favorite tools – an Arduino and a few parts from Sparkfun.

The build hinges on the fact that all shiny pokemon have a short animation whenever the player encounters them in the wild. This setup uses a fishing rod, so an Arduino Micro first presses the Y button to cast the rod, while the ‘duinos ADC listens to the audio signal until a bite is indicated.

A light sensor taped to the bottom screen of the 3DS then measures the amount of time the screen is blacked out. The extra animation for every shiny pokemon means this blackout period is about half a second longer. If the Arduino doesn’t see a shiny, it ‘runs away’, but if a shiny is detected a buzzer sounds to tell the extremely lazy pokemon trainer they have a shiny on their line.

From the video, it took about 36 minutes to find a single shiny pokemon, and about 8 shinies in the three hours of testing this rig has under its belt.

Galaga Mini-Cabinet using a Nintendo DS

galaga-cabinet-from-nintendo-ds

We’re not showing you the finished version of this tiny Galaga arcade cabinet because it doesn’t really testify to the awesome that was packet into this hack. In regards to the features the build is just nuts!. The user controls were customized to look like the real thing, and the attention to detail would make craftsmen from the gilded age of dollhouses proud.

Update: [eLRIC] left a link to an even better forum thread build log as a comment. Among other thing it fully details the joystick modifications.

The machine is driven by a Nintendo DS, which donates its upper screen as the cabinet display. In the image to the right you can see that the lower display is still accessible through an opening in the back of the cabinet. The joystick is a small multi-directional switch which was altered by adding the red ball. It was also housed in a custom metal bracket that includes a washer to limit the movement of the stick. Also shown on the right are the lights for the marquee as well as the two coin-slots.

Check out the video after the break to see the game play. Despite its size it still seems really playable, but if you need something larger you could model your own build off of this project.

Extreme Game Boy hack plays titles from a wide range of systems

gameboy-ds-in-original-gb-case

[Akira] can play any Game Boy, GBC, GBA, NES, SNES, or SMS game while on the go thanks to all the work he put into this portable gaming hack. The outside seems familiar; it’s an original Game Boy case. But you should immediately notice that it has a few extra buttons. That’s the first clue that what’s inside isn’t stock… which is a huge understatement.

The idea for the project started off rather simple, but quickly got out of hand (check out the build log for full details on that). He thought it would be nice to have a backlight for the original screen. After mixed results he scrapped the original mainboard and started anew with some Nintendo DS Lite hardware. It had a broken LCD connector so he tried a couple of different fixes to get it working again. After some success he started adding more equipment, like the extra pair of buttons, a better speaker on the battery door, and the microSD add-on you can see above.

You can catch a demo of the finished goods after the jump.

Nintendo DS mini USB plug

DSCompare

Noting that so many of his electronics are using the mini USB plug for charging, [Xavier] decided to modify his Nintendo DS to charge via the same adapter. It looks like the existing adapter is basically a proprietary mini USB plug, so replacing it was actually almost a perfectly clean swap job. He has nice pictures of the process and some helpful tips as well. If you’re thinking of consolidating your charging devices, this looks like a step in the right direction.

Hard Core Nintendo DSI hacking

dsi (Custom)

So, you hacked your DSI did you? Let me guess, you ran a flash cart. No? You probably added some LEDs then right? No? You must be pretty hard core, did you add a NES controler? No? Well what did you do?

We still have no idea what this guy is doing. But he is doing it very meticulously. We found [Micah Dowty]‘s photo stream on flicker and we were instantly pulled in. He has done some extensive modifications to his DSI. He has spread its innards for all to see and begun hacking. It appears as though most of this is for memory dumps and direct access to the RAM in the unit, but frankly we just want to stare at these pictures.
