NFC Tags Control Your Home’s Lighting

Here’s a home lighting hack that doesn’t require you to think about it after the initial setup. Instead of requiring the user to launch an app and select a lighting state, it uses NFC tags to select a lighting configuration. The tags can be placed in different parts of the house so that setting your phone on the table beside the door while putting your coat on will turn everything in the house off. Of course you need to crawl before you can walk so right now this proof-of-concept only switches the Phillips HUE bulb in the desk lamp.

That bulb is compatible with the Ninja Blocks system — but a Ninja Block or an Arduino with an Ethernet shield could be used to switch whatever you wish. The Ninja client code is an integral part of the system which is why the hardware side needs to relate to the platform. Also used is the On{X} service which bridges the gap between your Android phone and the home automation hardware. Once that is in place it’s only a matter of programming the NFC tags to do as you wish. Don’t miss a demo of this in the clip after the jump.

Freezing Android To Crack The Encryption

Build a better lock and someone will make a tool to open it without the key. Or in this case they’ve made a tool to discover the key using a trip to through the deep freeze. The Forensic Recovery of Scrambled Telephones — or FROST — uses cold temperatures and a custom recovery image to crack Android encryption keys.

Cold boot hacks go way back. They leverage use of low temperatures to slow down the RAM in a device. In this case, the target phone must already be powered on. Booting a phone that uses the encryption offered by Android 4.0 and newer requires the owner’s pass code to decrypt the user partition. But it then remains usable until the next power cycle. By freezing the phone, then very quickly disconnecting and reconnecting the battery, researchers were able to flash their own recovery image without having the encryption key cleared from RAM. As you can see above, that recovery package can snoop for the key in several different ways.

CASUAL Seeks To Make Android Hacking OS Agnostic

CASUAL-android-hacking-scripts

[Adam Outler] tipped us off about a cross-platform Android hacking suite he’s been working on. The project, which is called CASUAL, brings several things to the table. First and foremost it breaks down the OS requirements seen on some hacks. It can perform pretty much any Android hack out there and it doesn’t care if you’re using Linux, OS X, or Windows.

We’ve embedded two videos after the break. The screenshot seen above is from the first clip where [Adam] demonstrates the package rooting the Oppo Find5 Android phone. He then goes on to show off the scripting language CASUAL uses. This layer of abstraction should make it easier to deploy hacking packages, as CASUAL handles all of the underlying tools like the Android Debug Bridge, fastboot, and Heimdall (an open source Odin replacement which brings the low level tool to all OS platforms) . The second video demonstrates a Galaxy Note II being rooted, and having a new recovery image flashed.

The Universal Geospatial Light Switch

February 3, 2013 by Jeremy Cook 14 Comments

Home automation has existed in one form or another for quite some time, but we thought this take on controlling lights was quite interesting. Instead of having a menu of lights that you can turn on and off, this Android app lets you point your phone at the device and turn it on or of. Undoubtedly similar to how [Darth Vader] controls his lights at home.

Although the really technical details of this project aren’t listed, this setup reads the compass and GPS output of the Android device to figure out where it’s pointed in space. Combined with a script that understands the layout of the room, and an [X10] automation controller, it’s able to control lights accurately.

Be sure to check out the video of this device in action, or check out [Mike]’s [Project Rita] blog to see the other interesting projects that he’s working on!

Adapting The Nexus 7 For A Double DIN Car Dashboard Opening

January 29, 2013 by Mike Szczys 33 Comments

It turns out that the Nexus 7 Android tablet is the perfect size to fit in a double DIN opening. DIN is the form factor of a single CD head unit for an automobile. Many models have room for a double DIN, which is defined as 4″ high by 7″ wide. Once [Meta James] figured out that the dashboard bezel for his Subaru framed the Nexus 7 perfectly he set out to fabricate the mounting system for an in-dash tablet installation.

Unlike a lot of these dashboard tablet installs, [James] didn’t need any Bondo, sanding, or painting to get things to look right. Like we mentioned, the bezel is a perfect fit so his alterations are hidden behind the tablet itself. He removed the stock head unit and ordered a DIN adapter kit to get the black bracket plate seen above. He built an acrylic box the same size as a double DIN head unit, then mounted the plates to the sides and a Nexus 7 case to the front. This holds the tablet in firmly, lets him mount the entire assembly using the factory mounting points, and leaves plenty of room for the cabling that connects the device to the car. Since he already had a hands-free phone system he just uses that to amplify the audio fed to it via Bluetooth.

New IOIO Is Faster, Cheaper

January 25, 2013 by Brian Benchoff 29 Comments

For the last few years, [Ytai] has been working on the IOIO, a device that connects your Android devices to the other homebrew peripherals. There’s a new version of this really cool board out now that includes a few much-needed features like USB-OTG and a lower component cost that is passed on in savings to you.

A few months ago, our own [Mike Szczys] caught a glimpse of this new IOIO board. It’s the same size as the previous revision, but with USB-OTG, the new IOIO can be a master when connected to a phone, or a slave when connected to a PC.

In addition to USB-OTG, [Ytai] improved the power regulation circuit, and even went so far as to refuse royalties to the board to get the costs down. It’s currently available at Sparkfun for $40.

[Ytai] says he’s working on a few software upgrades to the IOIO, including making capacitive sensing a possibility and including support for stepper motors and controllers. There’s also support for the Raspberry Pi coming up, but we’re just glad [Ytai] managed to put a yo-yo graphic on the bottom silkscreen. Finally, and hopefully, everyone will know how to pronounce IOIO.

XBMC Workaround For Android Hardware Video Acceleration

January 22, 2013 by Mike Szczys 33 Comments

An unofficial, but fully functional release of XBMC should make the uber-popular media center software work with almost all Android devices. About six months ago the developers of XBMC announced that it had been ported for Android. That was true, but there was one caveat. The port was made functional on one specific Android device. The hardware company Pivos paid for the devs to add support for their Xios DS device. Although that build could be run on other Android devices, the hardware video acceleration could only be use if it was the same as the Xios. When not using the hardware acceleration many common video formats would only play at a few frames per second, if at all.

This build is a workaround and is not officially supported. What it brings to the table is the ability to use an external media player with XBMC. This way any video format which your Android device is capable of playing (with hardware acceleration) can be launched from XBMC but will be played by the native video application. We haven’t tried it for ourselves. If you have we’d love to hear about your experience in the comments.
