Nook Simple Touch As A Glider Computer

October 12, 2012 by Mike Szczys 13 Comments

Look at the beautiful screen on that Nook Simple Touch. It has a lot of advantages over other hardware when used as a glider computer running the open source XCSoar software. The contrast of the display is excellent when compared to an LCD or AOMLED. That’s quite important as gliding through the wild blue yonder often includes intense sunlight. The display is also larger than many of the Android devices that have been used for this purpose. There are a few drawbacks though. One is that unlike other Android devices, this doesn’t have a GPS module built into it. But the price point makes up for the fact that you need to source an external module yourself.

This isn’t the first time we’ve seen the device used as a navigational display. This other hack put a simple touch on a sailboat for the same direct-sunlight-readability reason. For $100, and with the ability to root the system for use as an Android device, we expect to see this to keep popping up all over the place as a simple interface for a multitude of projects.

After the break you can see a video comparing the software running on a Nook display to one on a Dell Streak 5 LCD tablet.

There’s A Friggin’ Cellphone In The Most Recent Entertainment Weekly

October 5, 2012 by Mike Szczys 131 Comments

Hackaday readers were stumbling over each other to send in a link about this Android cellphone inside of an Entertainment Weekly magazine. Thanks to all who sent it in, and keep them coming. We’d rather get too many tips than none at all!

The first thing we should address is the discomfort you will feel while watching the video after the break. If you’ve got any experience tearing open electronics to see what’s inside you will be physically uncomfortable watching this pair bumble through it. It makes us want to do some MST3K-style overdubbing of the video, but their content ownership claim in the description makes us sure we’d get an immediate take-down notice if we did so.

At any rate, what we have here is some really cool tech you almost certainly will not be able to get your hands on. In the image above you can see the small LCD screen to the right. It comes to life when the page is opened thanks to the sliding switch being pointed to in the image. A few television show promos will play before the device starts scrolling items from the CW Twitter feed. When the hardware is pulled out of the pages there’s some interesting tinkering to be done. Shorting the contacts on the keyboard overlay (about 8 minutes into the video) brings up an Asian-language menu which is pretty obviously Android.

This is not the first time the magazine has done something like this. CBS embedded video a few years back but we’re pretty sure that one didn’t use the full guts of a cellphone. It’s just too bad these issues are so rare (only 1000 are available in two cities) as we had a lot of fun hacking that Esquire issue with the epaper in it.

IPad External Battery Case Forced To Work With A Non-iPad Tablet

October 2, 2012 by Mike Szczys 10 Comments

[Carnivore] uses a Pipo Max M1 tablet. It’s an Android device that is very responsive thanks t the 1.6 GHz dual-core processor and it runs Jellybean (latest version of Android OS). The one thing he wasn’t so happy with is battery life. Under heavy load it lasts about three hours. When reading an eBook that use can be stretched to 10 hours. His solution was to add an external battery. It turns out the 9.7″ screen makes the body of the device almost exactly the same size as an iPad, so he made an iPad external battery case work with the Android tablet.

[Carnivore] started the hack by disassembling an iP6000 case which houses a 6000 mAh battery. He removed the dock connector and fitted in a 2.5mm power jack. Luckily the buttons on the Android tablet are in nearly the exact same place as those on an iPad, with the power button hole needing just a bit of enlargement. The case charges itself and the tablet’s internal battery using a microUSB port which means he no longer needs to carry around a special power cord. The new hardware increased the battery life by about 75%.

Galaxy SIII Hack Puts Android In Your Dashboard

September 21, 2012 by Mike Szczys 43 Comments

Here’s how you can have a hands-free, no worries about the battery, Android experience while you drive. [Steve] removed the head unit from his car and replaced it with a Samsung Galaxy SIII Android phone. The look is pretty nice, but we do have a few suggested improvements if you try this one for yourself.

It started simply by removing the factory stereo which left a double-height opening in the dashboard. [Steve] cut a piece of wood to fit the gaping hole, painting it a grey that would compliment the interior colors of the car. The phone is mounted on this plate, with plenty of room for the USB and audio cables. From there it is finished up with another wooden plate which has a cutout for the touch screen. See the final project, as well as glimpses of the installation, in the video after the break.

[Steve] demonstrates using the GPS features and playing music. We’d improve this in a couple of ways. First off, using something like the IOIO board you could add a physical volume knob, which we’re not interested in giving up for a touch screen quite yet. If you were willing to go the extra mile, a CAN-BUS chip could be added too that would monitor button presses from the steering wheel music controls.

Android Hack: Cracking WiFi Passwords With Your Phone

September 18, 2012 by Brian Benchoff 61 Comments

The WiFi adapter in your laptop has a special mode – monitor mode – that can be used to listen in on WiFi traffic and, with a little patience, can be used to crack a WEP password. Surprisingly, this monitor mode can’t be found on any Android device due in part to the limitations of the hardware. A group of three researchers, [Ruby], [Yuval], and [Omri], decided to spend their vacation adding monitor mode to their Android smartphones, allowing for a much more portable version of WiFi pwnage tools.

The phones used by the researchers – the Nexus One and Galaxy S II – used Broadcom chipsets that didn’t support monitor mode. To get around this limitation and allow the OS to see full 802.11 frames the team needed to reverse engineer the firmware of this Broadcom radio chip.

The team has released a firmware update for the bcm4329 and bcm4330 chipsets found in the Nexus One and Galaxy S II. The update may work for other phones with the same chipset, but don’t take our word on that.

There’s still a lot of work [Ruby], [Yuval], and [Omri] need to do. They’d like to add packet injection to their firmware hack, and of course create an APK to get this into the wild more easily.

If you have experience with kernel development and would like to help out, send the team an email. The source can be found at google code if you’d like to play around with it.

Video Preview: New IOIO Prototype

September 15, 2012 by Mike Szczys 9 Comments

We got our hands on this prototype of the new IOIO design. It’s a breakout board that makes adding hardware to an Android device pretty easy. [Ytai Ben-Tsvi] sent it our way, and took a bit of time to explain some of the differences between this board and the original version. You can see our video preview embedded after the break.

The size and form factor of the board remain the same, but the choice and layout of parts has changed. Most obviously, the USB-A connector is gone, replaced by a USB ~~mini-B~~ micro-B connector. This makes it possible to use the board as a USB-on-the-go device, or as a USB host device with the help of an adapter that will ship with the board. The JST connector is for external power. The previous revision included a footprint for it but it was never populated. There has also been an upgrade to the voltage regulation circuit, using a newer part as the switch-mode regulator.

There was a last-minute bug discovered in the layout. [Ytai] wants iron-clad 5V to ground short protection and is re-spinning the board to ensure he achieves that goal. He can’t say for sure, but as we mentioned in our previous post about the prototype, a price cut is planned. It could cut the current price of $50 down to just $30, but that won’t be decided until all of the choices have been made for the first production run.

IOIO Controller Replacement For An RC Truck

September 11, 2012 by Mike Szczys 5 Comments

This RC truck can be controlled with the tip of your thumb or the tilt of a wrist. That’s thanks to the IOIO which was inserted in place of the toy’s original controller. [Exanko] made the hardware changes in order to use his Android phone as the controller. The white circle is a software joystick that acts as throttle when your thumb moves along the Y axis, and steering when it moves along the X axis. But while he was at it he also included accelerometer input as an alternative control option.

The IOIO board has a Bluetooth dongle connected to its USB port as a means of wireless communication. The dongle was hacked to accept an external antenna, thereby increasing the truck’s range. There is also some on-board flair like LEDs for lights and even a laser diode for… well we’re not sure what that’s for. Get a better look at the hardware internals in the clip after the break.
