Disassembling the US Nintendo DSi
An anonymous reader writes "Yesterday iFixit tore apart the Nintendo DSi and found several internal upgrades from the outgoing DS Lite. It seems that an experienced hand can completely disassemble the DSi in less than ten minutes using standard tools, especially since the job does not require a tri-wing screwdriver. This should make repairing and tinkering with the DSi substantially easier. The DSi now includes two integrated cameras that, unfortunately, have only 0.3 megapixel resolution. This is certainly a bit underwhelming considering most mainstream phones have cameras of at least 1.3 megapixels. As for chips, Nintendo is using a Samsung MoviNAND integrated 256 MB Flash memory / MMC controller chip, as well as a custom ARM CPU + GPU is stamped with the revision code 'TWL.' The DSi's chips all had manufacture dates around September 2008, indicating that Nintendo has been stockpiling these devices for quite a while prior to the North American release."
I'm surprised that they decreased battery capacity. I thought the reduced battery life was a side effect of the component upgrades. Apparently, that's not the case. Even more surprising is that the DSi mainboard is technically smaller than the DS Lite, but the unit has a larger footprint thanks to an expansion board hanging off the side. The board appears to be the contact points for the system's buttons.
I wonder if the larger footprint was necessitated by the larger screens? One would think that Nintendo would shave off a bit of space from the sides, but perhaps that didn't yield as good of a grip as the DS Lite.
Javascript + Nintendo DSi = DSiCade
0.3 megapixels is equivalent to a resolution of 640x480 pixels, which is twice the resolution of each individual Nintendo DS screen. The lower resolution CCD costs less, and the images are far easier to process in real-time with the DSi's limited resources.
I am wondering if you can send the picture anywhere after you take it. with the recent sexting lawsuits I am sure nintendo doesn't want jr. high kids sending pictures of sex organs to each other in class on their DSi.
That could really kill off their new DRM ridden pile of crap.
0.3 megapixel pictures are far easier to share and probably far easier for the ARM CPU to manipulate than 1.3 megapixel pictures. From a usability perspective the megapixel makes a lot more sense than trying to edit a much larger picture on such a small screen or trying to use such a small device to transmit the picture wirelessly to your friend's DSi.
The real question is, does Flashme work with it?
I'm really curious if the various mechanisms for running homebrew applications still work.
I have an R4 chip from my regular DS - my guess is they've closed up whatever hole was opened and a new method will be found, but has anyone tested this so far?
How does this
The DSi's chips all had manufacture dates around September 2008, indicating that Nintendo has been stockpiling these devices for quite a while prior to the North American release."
mean that nintendo was stockpiling? They could have bought the chipsets and just built instead of you know stockpiling

A non-experienced one will take 10-30 seconds with no tools at all. This may not make repairing and tinkering with the DSi substantially easier

Or it might have something to do with the fact that the DSi was released in Japan in November 2008.
Till the DSi is rebuilt into something geeky like the Millennium Falcon or the Battlestar Galactica? That's the sort of hand held gaming that I can get behind!
The musings of just another geek and his junk.
Surely they are CMOS cameras not CCDs.
That they are, my apologies to the camera gods.
This rev of the DSi is really underwhelming. I traded my old DS phat in for $50 off of the DSi, and though the upgraded screen is nice, I'll never use the damned camera. It doesn't support mp3. Downloadable games are nice, but I haven't found a single one worth downloading at launch. I'm hoping somebody comes up with a way to play old snes roms on it via the SD card -- if that happens, then my purchase was totally worth it. Otherwise, I'd have stuck with a DS lite if I had that option.
Because it is Slashdot "The nuts and volts of news for nerds" Which means this documentation is now the first step of any modifications. I and many other NERDS, Love modding and getting the most bang for your buck. It is just like Car Guys who are always looking for more performance.
How in the fuck are pictures of the internals of an electronic device front-page worthy?
What? Get the fuck out.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Wow.
OP aside, please feature more stories about disassembled electronics. Thank you.
There are a number of DS homebrew games I'd love to use, if I ever have the disposable income to spare on the adapters and cards. There's a painting app ( http://colors.collectingsmiles.com/about.php ) which looks neat, especially if you are traveling and want to sketch something, or just like to doodle. There are also some PDA-like programs which might be handy, though I don't know how I'd find them useful.
ScummVM ( http://scummvm.drunkencoders.com/ ) is a homebrew app to let you play old LucasArts games, as well as newer (free) games made for the Scumm interpreter. (Yes, one could pirate the old LucasArts games. The morality of playing a no longer published game on a newer platform is not something I wish to discuss. I don't plan to pirate it, if that's any consolation to you.) There are some free games, such as several from Revolution Software, that have been re-released from Amiga to Nintendo DS.
There are even e-book and comic reader homebrew apps for the DS... though I've not used them. (I prefer paper books.)
I'd get a lot more geek cred if I were part of the nintendo DS demo scene, but I'm not. (: However, I hope I have adequately debunked your claim that all we'd want to do is use it to run pirated games.
Hummm .. what? This is Slashdot by the way, not Perez Hilton.
Components or GTFO!
That's better.
What adverts? I use adblock because I'm superior to you
Now I won't have to buy it.
Homebrew my arse. You want to run pirated games. Just admit it.
Is Linux a pirated copy of Solaris? No. Is Nintendo's Balloon Fight a pirated copy of Midway's Joust? No. Is Lockjaw a pirated copy of Tetris DS? No. Is MoonShell a pirated copy of Windows Media Player? No. Is DSOrganize a pirated copy of Hello Kitty Daily, an organizer for DS? Hell no.
I am wondering if you can send the picture anywhere after you take it.
I don't see any reason why it would use privacy rules different from the Wii Numbers used on Wii.
Each side of the sensor bar has half a dozen infrared LEDs in a line. But have you ever noticed that the dots on the Wii Remote sensitivity screen are always perfect circles? The screen actually reads the four biggest blobs (X, Y, brightness) and draws them to the screen as circles with radius proportional to brightness. So you're not seeing the direct output of the 128x96 pixel* sensor in the Wii Remote but instead an interpretation of this info.
* The effective resolution is 1024x768 because the remote's firmware uses brightness and area information to refine the estimated position of the centroid of each blob to 1/8 pixel increments.
They aren't, especially since all of the images are so small. It looks like they link to something, but when I click them, nothing happens.
Thank you.

"most mainstream phones have cameras of at least 1.3 megapixels"
Where? Most mainstream phones where I live is 3-5MP. I think iPhone is the only one with a limited MP.
TOTALLY front page worthy!!! iFixit is actually really great. I've ordered several screwdrivers and such from them!
Never have words so important been said so eloquently.

Can't wait for this to be (jailbroken? is that an applicable term?) opened up. As in, really, I can't wait, so I asked Nintendo how to become a developer "officially". Still waiting for a response, not expecting one.
Why do people lock down hardware? I definitely wouldn't have bought one myself without a clear path to being able to develop things for it :/

The TWL codename stands for TWeLve, as it is the 12th Nintendo Hardware platform. Can you name them all?
Chris
Can you boot Linux on that thing?
This is slashdot. We get hardons looking at picture of naked electronics. If you don't, try hanging out somewhere else.
I've abandoned my search for truth; now I'm just looking for some useful delusions.
