Turning the Samsung Galaxy Note 10.1 into a proper Linux box

deb

Over on the xda developers forum, [exception13] shows us the work he’s put into geting Debian running on his Samsung Galaxy Note 10.1, allowing him to dual boot Android and Linux on a single device.

The project is still in a fairly early state, but so far [exception13] has most of the goodies required for a decent Linux experience running already. There’s WiFi, bluetooth, sound, usb-otg and touchscreen support, as well as support for the Note’s S Pen, the Wacom digitizer that basically turns the Galaxy Note 10.1 into an Intuos touch pad.

There’s still a lot of work work to be done, including getting the camera up and running, as well as enabling the GPS receiver. Still, it’s a very cool project that puts the power of a proper desktop interface into a tablet with enough horsepower to get something useful done.

If you’d like to get this running on your Galaxy Note, [exception13] has a download avaiable over on Google Code. There’s also a video [exception13] put together demoing all the cool stuff his Note can do, you can check that out after the break.

Dedicated Pandora player plus AirPlay built around the Raspberry Pi

rpi-pandora-radio

[Shaun Gehring] wanted an Internet radio player. Although he did have some troubles along the way, the final project turned out very well. Housed inside this case which used to house a spindle of bland CDs is a Raspberry Pi that plays Pandora radio and serves as an AirPlay receiver.

The GPIO header of the RPi makes this project a lot easier. [Shaun] used Adafruit’s breakout board to solder connections for the six buttons and the character LCD screen. Plug some speakers into the audio jack and the hardware end of the deal is finished. The software side of things is very similar to the BeagleBone Pandora player we looked at in September. It uses a Linux distribution (Rasbian Weezy) and the Pianobar package.

Pianobar is very versatile. You can control it using a First-In First-Out file. Once [Shaun] figured out how to use mkfifo to set up the file, he was able to control it from a script by monitor button presses and echoing the associated command to the FIFO. The finishing touch was to add AirPlay support via the shairport package.

Playing video games on your office phone

So IT has your computer locked down, but if you’re lucky enough to have this model of telephone you can still play video games while at work. [AUTUIN] was at the thrift store and for just $8 he picked up an ACN videophone on which he’s now playing video games. We don’t know what magical second-hand stores sell functioning electronics of this caliber  but you should never pass up an opportunity like this.

It turns out the phone is running Linux natively. After some searching [AUTUIN] found that it is possible to telnet to a root shell on the device. Doing so he was able to figure out that the phone uses standard packages like ALSA for the Audio and /dev/input/event0 for the keypad. It even includes an SD card slot so he loaded one with a Debian image and used pivot_root to switch over to that OS. At this point the phone is his to command and of course he loaded up a video game which you can see in the clip after the break.

Raspberry Pi wedded to a DSLR

This is a Raspberry Pi outfitted in a DSLR battery grip. [Dave H] was very interested in the idea of combining a single-board computer with a high-end camera. The size and cost of such a computer was prohibitive until the RPi came along. He managed to fit the board into the broken battery grip he had on hand, and he already has the prototype up and running.

[Dave's] alterations to the battery grip allow access to the USB, Ethernet, and Composite video ports. Powering the RPi was a bit of a challenge. He tried using an iPhone charger with four AA batteries but that only provided 4.2V. After going back to the drawing board he discovered he could rework the parts that he removed from the grip, using a Cannon 7.2V 1800 mAh battery. So far he can automatically pull images from the Camera and transmit them over a network connection. But since the RPi is running Linux, there’s a whole world of hacks just waiting to be exploited. What comes to mind first is image manipulation software (like ImageMagick) which has a command-line interface.

Fattening a thin client to run a Debian desktop

While watching his thin client boot up [Nav] noticed that it’s using some type of Linux kernel. He wondered if it were possible to run a full-blow desktop distribution on the device. A little poking around he got a Debian desktop distribution running on a thin client.

The hardware he’s working with is an HP t5325. It’s meant to be a dumb client, connecting to a backend machine like a Windows Terminal Server or via SSH. But it’s got a 1.2 GHz ARM processor and [Nav's] preliminary investigations revealed the it’s running a version of Debian for ARM. He used CTRL-C during the boot sequence to derail that process and dump him to a shell. The login was easy enough to guess as the username and password are both ‘root’.

Once he’s got that root access it was slash and burn time. He got rid of the HP-specific setup and made way for additional Debian modules like the apt system. This isn’t trivial, but he’s worked out a bunch of sticking points which makes the process easier. With the repository tools loaded you can install Xserver and Gnome for a full-blown desktop on the embedded hardware.

Flashing Arduinos with a Zipit

zipit_arduino_flashing

[Giacomo] finds that every once in awhile, he needs to flash a sketch to an Arduino while on the go. While he doesn’t always carry his laptop with him, he almost certainly has his Zipit Z2 on hand. He prefers to use the Zipit because it’s tiny, it uses Debian, has built-in WiFi, and can run for about 5 hours before requiring a recharge. The only shortcoming is that the device lacks a serial port.

Following instructions we featured last year he added a serial port to his device, then built a small converter cable that allows him to connect it to virtually any Arduino. He says it only takes a moment to get avrdude up and running on the Zipit via apt-get, and once that’s done, he is in business. He wrote a short script that saves him from entering the flash command over and over, so the process couldn’t be simpler.

He does mention that since the Zipit does not have a DTR line, Arduino resetting must be done manually. For the convenience of flashing sketches from the palm of our hand, we can deal with that.

Check out the video below for a quick demonstration of his setup.

Nexus one gets Linux

Considering how hackable the Nexus One is already, we can only imagine a whole new host of interesting things thanks to Ubuntu running on the device. [Max Lee] set his heart out on getting not just Ubuntu on the Nexus One, but also Debian, and he wrote a perfect install guide to help out those wanting to give it a shot.

He cheated a little bit by having Ubuntu run in the background while the X11 interface is simply VNCed, but he still did an awesome job with plenty of pictures and details to help you achieve Ubuntu on your Nexus One.
