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.

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.

[Raguaviva] shows us in this video how he’s using an optical mouse as a low quality camera for his DS. This seems like a pretty cool hack, but we’re at a loss to think of a good use for it. As he gets to the end of the video, he seems to also have trouble thinking of a good use for it. Do you guys have any ideas?

Now that the Nintendo DSi has been officially released in the US, the team at iFixit has worked their magic. That magic being: completely disassembling it. They found the new 840mAh battery to be much smaller than the DS Lite’s 1000mAh. The device features two cameras, but both are a paltry 0.3megapixels. They note that this is the first Nintendo device that they’ve taken apart that didn’t require a tri-wing screwdriver.

Many more DSi compatible flash carts are available now than our initial report in December, so you can pick up a Nintendo DSi for homebrew without worry.

You can get most of the old NES games for the DS, but they just don’t feel the same. Sure your hands still cramp up, but its just not the same cramp we remember. What is the solution? Put an old Nintendo Entertainment System controller on your DS.  [Parker] did exactly that. The method he used is fairly strait forward. He opened the DS, wired extensions onto the buttons he wanted to use to a controller. Instead of making it permanent though, he chose to wire it through the GBA slot. This allows him to plug the controller in whenever he wants to use it.  This reminds us of the PSP with a SNES controller we covered back in October.

You can see a video of it in action after the break. You’ll notice in the video, he has also modded his buttons to have LEDs behind them.

In the comments, [tri-edge] points out that you can follow his build in the acidmods forum. There seem to be some other variations as well, including an SNES controller.

[dark sponge] decided to make his DS lite, solar powered. Or, at least charged via solar panels.  He was able to find solar cells that were 60×60 mm, which means he could fit 4 of them on the outside of the DS. This gives him a total of 6V at 80 mA output. These panels charge the battery between uses. The DS has to be open and laying on its face for all 4 panels to be exposed, but this way of mounting them didn’t alter the pocket-ability of the unit. He says he’s been using it for a while and hasn’t had to plug it in yet, but we have concerns about wiring the panels directly to the battery. As [cyrozap] points out in the comments on the instructable, this is a Lithium Ion battery, shouldn’t there be some charging circuitry involved?

[palmertech] and [Bibin] have both completed backlight projects for the Game Boy Pocket recently. The most difficult part of the transplant is carefully removing the reflective backing on the LCD. After a thorough cleaning, a diffuser and backlight panel were added. [palmertech] used a backlight salvaged from a DS, while [Bibin] built his own using LEDs. You can see his backlight in the video embedded below. There’s a disassembly video too.

South Wales Police raided a store in Cardiff seizing 1,800 Nintendo DS flash carts. The devices can be used for playing pirated games or running homebrew software. In the UK, the carts are illegal under the Trademarks and Copyright Acts. The 21-year-old suspect had imported the devices and was selling them both online and in-store. He had over 1,000 devices in his home. Many of them packed and ready to ship. Official statements by the Entertainment and Leisure Publishers Association claim that the hardware irreparably damages the DS handhelds.

We covered [Steve Chapman]‘s Nintendo DS control for his Canon DSLR in September. He’s since improved the software so that it has a timer for sunset/sunrise amongst other things. He also shot about 30GB worth of timelapse images while in Vancouver and assembled a couple test videos. He’s still working out the processing to take full advantage of the 15megapixel images. We look forward to future results since YouTube is now using a much larger player for high def content.

OpenSound Control protocol is an emerging standard for communication between musical programs. It’s meant to replace MIDI. The DSMI, DS Music Interface, team has just added support for OSC. You can now use your DS as generic OSC music controller over WiFi. OSC has TCP/IP support built in, so there is no need to run a host sever to talk to DSMI like you did when they only supported MIDI. We’ve seen OSC used in other projects like the monome. It’s also the basis for the multitouch communication protocol TUIO.

A month ago, we reported that Nintendo’s new DSi portable didn’t work with any of the current crop of flash cartridges. Things didn’t look good for homebrew. Here we are a month later and looking at the release of the Acekard 2i. It’s the first DSi compatible flash cartridge. The features appear to be identical to previous versions and we expect other manufactures will be updating their product lines in short order. You can find a video of the Acekard 2i after the break.

These carts may exist because of pirates, but we happily use them for homebrew. There are a lot of great programs out there; here’s a list of 24 apps that are dedicated to music creation. You can run Linux on it too. It’s as easy as copying a file to a flash drive. If you have a DS and aren’t using homebrew, you’re wasting it. We’ll be picking up a DSi as soon as they’re in the US (they’re region locked).

Adding LEDs makes everything better. Watch this video as a regular old DS gets turned into one of the most awesome things on the planet. A ton of LEDs were added, some to the body, some to an extra cartridge, some behind buttons. Parts are wired into the speakers, so you get nice effects to your music. We’ll bet the battery life suffers, but who cares. This thing is worth it. This was originally taken from Nico Nico Douga, which overlays the comments on the video.

[bunnie] managed to pick up a Nintendo DSi while in Japan. It seems he had the device running less than an hour before he tore it down for an impromptu hotel photoshoot. There’s nothing too surprising and he mentions that the CPU certainly feels more capable than the previous model, which may explain the shorter battery life. The ARM processor sits under an RF shield directly below the WiFi card. The best photo is the top side of the board with every single debug point labeled in plain English on the silkscreen. We’re sure that’ll help with the development of new homebrew hardware.

[bunnie] has posted some interesting teardowns in the past. Have a look at his Sony XEL-1 teardown to see the inner workings of an OLED TV.

The latest version of the Nintendo DS, the DSi, has officially launched in Japan. It features larger dual touchscreens, dual cameras, and an SD card slot. The members of GBAtemp.net have decided to tackle the most important question: will it run homebrew? Current DS systems just need a purpose built flash cartridge to load homebrew software (usually stored on MicroSD). Forum members have tested at least 10 different flash carts, and none of them worked. While not completely exhaustive it’s proof enough to us that current generation carts will not work. We hope this is something that can patched with a new firmware. Most carts load their firmware off the flash, so upgrades are easy. The blocking of homebrew maybe a side-effect of Nintendo’s announced region-locking on the DSi.

We hope this gets sorted out soon. Maybe we’ll see hackers figure out how to take advantage of the SD slot instead. If you’ve got a Nintendo DS, there’s no excuse not to be playing with homebrew. It’s as easy as copying files to a card. We’ve had success with the DSTT, which you can find on DealExtreme for just $10.

Using a custom built cable connected to the lower GBA slot and a copy of Canon’s SDK, [Steve Chapman] has come up with a very clever way of taking pictures remotely with a Nintendo DS Lite.

Currently the software supports bracket shooting as well as bulb mode. [Steve] points out that he is currently testing an audio based trigger system using the mic built into the DS and the software is still a work in progress.

While the weight saving benefits of using a DS instead of a notebook are obvious, there are things you do give up going this route. Traditionally, when you tether a camera to a computer the photos are saved directly to the computer where you can view the image on a much larger monitor. With the DS, it seems all you can do is remotely trigger the camera. Given the size and resolution of the screens maybe that’s all it can do.
