Update: more pink wireless-terminal hacking

[Dave] poked around inside of an IM-ME wireless toy and compiled his findings. He read about the device when we covered it in November and picked up a couple to see what he could do. He patched into the debug port in the CC1110 processor and enabled it by performing a chip erase. He then began mapping out how the processor connects and communicates with the qwerty keyboard, the wireless radio, and the LCD screen. The board is full of test points which make the hardware easy to access. [Dave's] experiments show that this hackable device is full of potential so let’s see what you can do!

PS3 wireless visual interface ( Free Play Games Online)

[Technott's] at it again, this time extending the Playstation 3 with a wireless interface. This handheld isn’t actually a PS3. It provides a wireless connection to your PS3 to receive audio and video, as well as to manage controller data. Think of it as a wirelessly tethered handheld that allows you to play Playstation when your wife is watching the Real Housewives. This is similar in size to his Xbox 360 WVI but the case shape and appearance are a big step up (not that we disliked that one). We’ve embedded a video tour of the device after the break.

Composite video output from chumby

[bunnie] posted this pretty slick way of getting composite video out of a Chumby. The Chumby is an open source connectivity device that has already seen some decent hacking. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.

Reverse engineering off-brand media players

[Marcan] picked up this device on the cheap and is working to reverse engineer the controller. This media player is an off-brand Chinese model that can be had for the low-low price of $33.97 with free shipping. That’s worth it just to scavenge the parts for other projects, but the challenge here is to hack the controller because a datasheet was never produced for it. Warm up your logic analyzer, check out the wiki, and you can be pounding away at this ARM926EJ-S based system in no time.

The call to arms comes from [Marcan's] blog. You may remember him as the guy who is working to solidify iPhone sync in Linux or… what else did he do? Oh yeah, he had this little project called the Wii Homebrew Channel a while ago. Get involved and you can learn from some folks who really know what they’re doing.

[Thanks Mr. Seeker]

How to root a Nook

Here’s the latest in rooted consumer devices, nookdevs.com has rooted the Barnes & Noble Nook eBook reader. The process is extremely easy, as the operating system is stored on a 2GB SD card inside the device. In fact, once you have the case open the hard part is over. From there, the card should be backed up for safe keeping. Now mount the card, enable the Android Debug Bridge and reassemble. The Android SDK can then be used to log into a shell on the Nook wirelessly.

We’re not sure there’s much that can be done past this point yet. It’s up to you to get Doom running!

[techknott]’s portable dreamcast

[Sydney] sent in this fantastic portable Dreamcast, built by [techknott], in response to the one we posted yesterday. While we agree, this one is much more polished, we want to point out why the post yesterday is more Hack A Day material. Sure, it looks more “hackish”, but that’s not what we are referring to. What we want to draw your attention to, is the lack of information. Yesterday, there was a build log. Today, there is not. Sure the other one could have had much much more information and we’re not commenting on which one is “better”. We’re just reminding you to please please please document your projects. Oh, and also, this thing is awesome.

Odroid: all the open, none of the contract

The Odroid derives its name from the combination of Open and Android. The hardware is aimed at the portable gaming market and runs Android. The specs are amazing, the device is open and begging you to develop for the platform.

The Samsung S5PC100 System-On-A-Chip provides the device with an ARM Cortex-A8 processor running at 833MHz. The usual suspects are all here, a capacitive touchscreen, accelerometer, SDHC slot, and WiFi. What you usually don’t expect to see is a serial debugger and 720p HD output. But the best part, we get all of this without a 2 year contract or the hardware being locked down as we’re used to with and Android based cell phone.

8-bit device quenches iPhone envy

[Peter] deserves an award for doing more with less. He’s built a handheld device based on an AVR controller that has features normally associated with much more powerful devices. Here’s what it doesn’t do: no phone calls, no text messages, no accelerometer, and best of all no app approval needed. What it does do is leverage inexpensive, readily available components combined with common homebrew development techniques to create a touch sensitive handheld.

The demo video embedded after the break details the device playing video, rendering 3D objects, and displaying pictures and ebooks with touch scrolling. All of this is running at 60 fps for a smooth picture. The whole thing is no larger than the 320×240 LCD that he salvaged from a broken MP3 player. An Atmel AVR ATmega644 microcontroller ties together the display, a resistive touch screen, and a microSD card for storage. The chip also controls the backlight, a Lithium Polymer battery, and uses USB for PC connectivity, charging, and even a mouse or keyboard interface. He etched the PCB himself for surface mount components and managed to do it with just four jumpers needed on the underside.

This is a big leap forward from the last AVR based touch sensitive device we saw. All of the functionality seen in the demo is run using 4k of memory and 32k of programming space. Because [Peter's] powering this at 3.3v the system clock is limited to 12MHz but he’s managed to make it work. We asked him to post code and schematics and he didn’t hold back. Head over to the microtouch project page to download the code, Eagle CAD files, and PCB artwork. All of the demo files are there just waiting for you to build on his hard work. When you’ve got something running, don’t forget to share it with us!

Midify now available

The people at Division 6 have begun selling Midify, a board that add a MIDI port to an DS and many other Nintendo handhelds. The board has 12 outputs, plus two for power and two for the MIDI port. Configuration and mapping are also very simple. This is the same board that was used to add MIDI control to a microwave.

Hack Guitar Hero DS into a guitar controller

[Eric Ruckman] sent us this awesome Guitar Hero hack. He wanted to get a more “true to the series” game play out of his DS when playing Guitar Hero: On Tour. If you’ve seen the adapter that comes with it, you’ll understand his desires. He found a wireless PS2 Guitar Hero controller on EBay to hack.

He’s cut a hole in the controller and removed all the guts. In the picture above the DS fits in the hole to allow strumming in the correct position. The controller buttons are connected to the DS by wiring into the adapter. He’s added an FM transmitter to the controller so he can play the sound through his home sound system.

No Nintendo DSi homebrew

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.

Control your camera remotely with a DS

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.

Nintendo DSi teardown

[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.

LED crazy DS

Click To Play

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.

Nintendo DSi gets its first flash cart

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).

UK raid seizes 1,800 flash cartridges

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.

Gameboy Color boot ROM

It’s only been a week since the Super Gameboy’s boot ROM was dumped by [Costis] and he’s already at it again. This time he’s managed to grab the Gameboy Color’s boot ROM. He found the newer Gameboy Color’s hardware is able to cope with a clock speed up to 100MHz, so the original clock increase trick he used on the Super Gameboy wouldn’t work again.

Instead he discovered a quick disconnection of clock and power before 0xFF50 would make the Gameboy jump to a random area within the ROM. Then it was only a matter of entropy, luck, and some special NOP instructions until eventually he had the boot ROM. Keep up the good work [Costis].

PSP Go gets butchered (teardown)

Not due to be released until the beginning of October, a PSP Go demo unit (shipped to G4TV) has already earned itself a teardown from [iFixit]. Among what was discovered:

- Once a few screws are removed, the battery is user replaceable (as-in: no soldering iron required)

- Wireless connectivity is only supplied through a 802.11b chip (no update to ‘n’, or even ‘g’, by Sony)

- Almost all chips are EMI-shielded (making them a bit more annoying to get to)

With a cheaper version of the PS3 ready to hit shelves, one can only wonder whether the relatively high price tag on this new PSP is worth it.

Update: It seems as though no party involved wanted the info leaked this early, which explains why the video and picture gallaries (up courtesy of Google) have been removed.

With Zipit, who needs a netbook?

[Hunter Davis] keeps rolling out the hacks for the Zipit. In the past he showed us how to run DOSbox, and then how to get NES emulation working on this tiny device. Now he’s got Linux kernel 2.6.29 running Fluxbox with mouse (newly added), audio, and WiFi functionality. Follow his step-by-step flashing instructions to load the kernel into the Zipit. Once flashed, a partitioned microSD card servers as the filesystem and swap.

Who needs a 10.1 inch screen or an Atom processor when you can get this 2.8″ QVGA beauty with an XScale processor for around $40?

[Thanks Matt]

Vintage Hack – Game Boy Camera

Back in 2005, a member of a French robotics team named [Laurent] wrote a wonderful how-to that we somehow missed on using the Game Boy Camera as a vision device for a robot. The images above are actual shots from his project. The Game Boy Camera features a stunning 128×123 pixel resolution in a gorgeous 4 color gray-scale palette. Possibly the most attractive feature of this hack is that it is still possible to get a hold of these cameras for under ten dollars on ebay.

He connected the camera sensor to an Atmel AT90S4433 using a combination of digital and analog signals, and then used the microcontroller to echo the data back to his PC. His write up includes schematics for wiring up the sensor/microcontroller, the datasheet for the sensor, his C code for the whole project, and an easy to read pin out of the GBC connector. Although his project simply offloaded the image to a computer, it would be entirely possible to have the microcontroller respond to the image or simply just log and store it. It would also be just as easy to replace his Atmel chip with your own favorite microcontroller, as long as it has a couple Digital I/O ports and at least one Analog port (or an external analog to digital converter).

UPDATE: Good catch r4v5, it would require an ADC, not a DAC.
