[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to connect an Arduino to the DS. For testing he’s soldered an IDC plug to the cartridge cover pin interface but this only requires four connections. The Arduino can both send and receive data from the DS lite as shown in the example videos after the break. The data access is made possible by making the Arduino look like a controller that the DS is happy to talk to.
[Epokh] has release some homebrew software that uses a Nintendo DS as a voice reader for documents. This is extremely useful for blind and visually impaired folks who normally use screen readers but can utilize this technology for reading books, documents, and email on the go. Future versions look to add an email client and implement OCR via the camera for reading documents on the go.
The flite package is utilized to provide the text to speech functionality. We’re familiar with this package and judging by the video after the break, it lost nothing in the port to the DS hardware. [Epokh] pointed out that similar readers can cost $1500 when a DS sells for around $130. We can’t wait to see the final version fleshed out!
Sometimes we wonder if we’re making good choices with PCB layout when using EagleCAD. Watch how the pros do it with a video of an hour-long Adafruit PCB layout session compressed into seven minutes.
[Elijah] documented his RepStrap build. This is a chicken-or-egg project in that RepStrap machines are built without the assistance of an already existing RepRap.
I’m sure nobody will raise an eyebrow when you pop out that roll of duct-tape and affix your phone to the airplane window. That’s what [floe] did to make this airline flight time-lapse video with an Android phone. Aren’t you supposed to turn off all electronics for takeoff?
It’s hard to believe we missed this one from a couple of years back but we’re thankful that reader [Christian] tipped us off about it. This a Nintendo DS with two tablet pc screens being used as an external display. He’s using an FPGA but not to emulate the processor. It is translating the video data from the DS board into usable signal for the larger LCD screens. In the video after the break you can see that pen input has been implemented, with the FPGA sending location data back to the DS.
[Neal], the creator, priced the project out at around $580. It’s worth a lot more considering the know-how needed to get the video scaling and pen input right using the FPGA. It won’t fit in your pocket, but it doesn’t have a case either so it’s not going anywhere anytime soon.
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.
[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.
