One Kindle Launcher To Rule Them

Ask around and chances are you can find a friend or family member that still has their early generation Kindle but doesn’t use it anymore. There are quite a number of different things you can do with them, and now there’s a single Launcher that works for all models of hacked Kindles. KUAL is the Kindle Unified Application Launcher.

Loading the launcher on your device does require that it be Jailbroken/Rooted, but that’s really the entire point, right? Once on your device the system is easy to configure. Menus themselves can be customized by editing the XML and JSON pair for each list. The screenshot on the left illustrates some of the applications you might want to run. We could see a VNC viewer being useful, and everyone likes to have games — like Doom II or the entire Z-machine library — on hand when they unexpectedly get stuck somewhere. But MPlayer? Does anyone actually use their ePaper device to watch videos?

Jailbreaking The Kindle Paperwhite

October 5, 2012 by Brian Benchoff 32 Comments

The Kindle Paperwhite, Amazon’s newest e-ink reader featuring a touch interface with a higher contrast display, is now officially jailbroken.

[geekmaster], the geek master behind this hack, based his jailbreak off [Yifan]’s previous hack to jailbreak the Kindle Touch. Installation is a snap, and only requires you to upload the data.stgz file to the root directory of the Paperwhite and restart the device. On the next boot, the Paperwhite will be jailbroken, allowing you to do tons of cool stuff with a tiny Linux device connected to an e-ink screen.

We’ve already seen a few really cool uses for jailbroken Kindles including a weather station display and a serial terminal for your Raspberry Pi. Cracking the newer and better Kindle Paperwhite means those e-ink projects you’ve been thinking about building just became much more attractive.

One word of warning from [geekmaster], though: USB downloader mode isn’t yet enabled. If you brick your device, you’ll need to connect your Kindle to a serial port. This shouldn’t be a problem for Hackaday readers, but it is something to watch out for.

Turning A Kindle Into A Weather Display

September 17, 2012 by Brian Benchoff 29 Comments

Since the first time [Matt] saw an e-paper display, the idea of using it as a regularly updated, non real-time display consumed him. It really is the perfect platform for very readable calendars, agendas or, as [Matt] found out, a weather display.

[Matt]’s build uses a server to fetch and parse weather data and forecasts from NOAA. This data is then inserted into an SVG file, rendered, converted into a PNG, and finally converted into a grayscale, no transparency image required by the Kindle.

After the image is crafted by [Matt]’s server, a small script running on the Kindle fetches the image, clears the screen, and displays the image. This entire process happens twice a day, often enough for [Matt] to get a good idea of the weather outside without having to look out a window.

The really striking feature of [Matt]’s build is how good his weather display looks. The wonderful iconography of this weather display comes partly from graphics found on The Noun Project, with a few weather conditions drawn by [Matt] himself. It looks great, and is an awesome example of an excellent use of e-paper.

Using A Raspberry Pi As Your Travel Computer

September 11, 2012 by Mike Szczys 29 Comments

Do you think you could travel for the entire summer and leave your laptop at home? [Gef] did just that. With the help of his Kindle he used a Raspberry Pi as his travel computer. This was an easy association to think up, since he planned to bring the Kindle along as his reading material anyway. All it was going to take was some creative hacking to get it working as a display for the single-board computer.

The Kindle is merely connecting to the Raspberry Pi through a terminal emulator. This happens via USB, and requires that you Jailbreak the kindle and install a package called USBnetwork. The problem with the technique is that you’re going to go crazy trying to use the tiny keyboard that is built into the eBook reader. [Gef] decided to take a USB keyboard along with him, but how is he going to use it to control the terminal screen on the Kindle? The answer is the ‘screen’ application. We’ve used it a lot to keep programs running on a machine after we’ve exited from an SSH session. It turns out it can also be used to host multiple users on the same terminal session. Pretty neat!

Tethering A Kindle For Free 3G

February 27, 2012 by Brian Benchoff 94 Comments

[Excelangue] just posted a guide to using the free 3G connection in your Amazon Kindle to browse the Internet on your computer.

The hack requires a Kindle Keyboard 3G and the free worldwide Internet access that comes along with the purchase price. After jailbreaking the Kindle and applying a USB network hack, [Excelangue] managed to connect his laptop to the Internet through his computer. The process of tethering the Kindle’s 3G is remarkably easy, but we expect a one-click solution will pop up on the web sometime this week.

Of course we have to note here that tethering a Kindle is against the Amazon terms & conditions, and the data going through your Kindle is tied to a unique ID. If you do this, Amazon knows who you are and is more than likely willing to brick your device. [Excelangue] is looking into tethering to the Kindle over WiFi so Android and iOS devices can get in on the action, but he’s still in the process of experimenting with his build.

Tablet Cover From Old Hardcover Books

February 15, 2012 by Mike Szczys 17 Comments

Here’s a way to look hip and destroy books at the same time. This table cover is made from an old hardcover book. It’s not difficult to do, an afternoon is all it takes, and if you follow all of the instructions we’d bet this will hold up for a long time.

It’s basically another version of the Moleskine cover for the Kindle Fire. You find a donor book (second-hand shops are packed with ’em) with a hardcover which you really enjoy. Kids books would be the most fun because of the artwork – if you can find one thick enough. With book in hand remove all of the pages. This will leave the binding a little flimsy, and since this is a project by the company which make Sugru, you can see why they used the moldable adhesive for that purpose. But check out the brackets in the picture above. They covered the Kindle in cling wrap, then molded Sugru around the corners. Once set, it can be peeled away from the plastic wrap, but will retain its shape. Nice.

Custom Screensaver On The Non-touch Kindle 4

January 5, 2012 by Mike Szczys 98 Comments

[Kubbur87] put together a guide to replacing the Non-touch Kindle 4 screensavers with your own images. We’ve already seen a way to remove the Special Offers banners from the newest version of Kindle Hardware, this hack lets you use your own 600×800 Portable Network Graphics (.png) file instead of the images pushed to the device by Amazon.

Frankly, we’re shocked at how easy this hack is. [Kubbur87] puts the device into developer mode, enables SSH, and then goes to work on the Linux shell within. It seems the only line of protection is the root password which he somehow acquired.

After the break you’ll find his videos which show how to enable developer mode and how to perform this hack. By putting a file named “ENABLE_DIAGS” with no extension on the device when it is recognized as a USB storage device you’ll gain access to the diagnostic menu system. From there it’s just a matter of cruising that menu to get SSH access. Like we said, you’ll need the root password, that that’s as easy as naming your favorite video game character from the 1980’s.
