Unlocking Multitouch For Droid And Nexus One

January 25, 2010 by Mike Szczys 23 Comments

We’re fans of pinch-zooming and that means multitouch. Although the interface is natively supported by both the hardware and operating systems of the Nexus One and Droid phones, it is locked out of the stock installation. You can make multitouch work on both handsets if you’re willing to do a little firmware alteration.

The coding has already been done for you, it’s a matter of loading a custom kernel. Both the Nexus One and the Droid have been rooted, and that’s what you’ll need to do to unlock multitouch with new firmware. In addition to gaining full access to the device OS, you’ll need to load up some different apps that support pinch zooming, etc. Luckily, these are readily available and you may like them better than the stock browser, maps, and photo applications.

Android G1 Serial To Arduino

January 25, 2010 by Caleb Kraft 16 Comments

With the ability to get root access to some of these new powerful pieces of hardware we call cell phones, we’re a bit surprised we haven’t seen more interfacing with external hardware. Here’s an example of some rudimentary connections between an Android G1 and an Arduino. To do this, you must have your G1 rooted, have the Android SDK installed, and then a custom python program running. There is also a simple level shifter from 3.3v to 5v necessary for the connection to the Arduino. You can get all the details from the instructable. They’ve documented the process quite well adn we’re excited to see what kinds of stuff people come up with.

Nexus One Rooted

December 31, 2009 by Mike Szczys 16 Comments

You know it’s getting a bit ridiculous when hardware that hasn’t hit the streets is being rooted. That’s exactly what has happened, root access can now be achieved on the Nexus One. [Paul] found an exploit and packaged it nicely so that anyone can do it. We do wish he had shared the details of the exploit but we’re not complaining.

If you’re not in the know, the Nexus One is the fabled Google Phone now come to life. It’s slated for release in 2010 and some think that will be officially unveiled at a January 5th press conference. That’s right, unveiled. The device has been cracked yet it doesn’t officially exist. What it does do is join a growing number of rooted android phones.

Freerunner With Android, New Case, Battery

December 27, 2009 by Mike Szczys 6 Comments

[Dennis] got snowed in after the biggest storm in the history of the state hit. Like any good hacker he didn’t let the time go to waste. He decided to dig out his Neo Freerunner to give it a decent battery and a new OS.

The original battery for the Freerunner has a controller board integrated into the package. [Dennis] pulled out the board and attached it to a portable DVD player battery. After running it through a discharge cycle with another hack of his, the board learned the new battery capacity. The larger battery plus a fast-charger from SparkFun required a larger case. He made it happen by combining a 2.5″ HDD case with the original body courtesy of some JB weld. The final portion of the hack was to load up Android which is as simple as untarring the package onto an SD card.

It’s a bit big, but the battery will last and he’s got an open platform. Nice work!

Nook Rooted Without Being Opened

If you’ve got a nook, and wanted to get root privileges, but really didn’t want to open up your fancy new toy. We have good news. The people over at nookdevs have found that the nook looks for updates from the external microSD slot at boot time. Simply download the patch, load it and boot. Though it was previously possible to get root privileges before, you had to physically open the device. While we would have opened it anyway, we understand that there may be people who prefer not to.

Odroid: All The Open, None Of The Contract

December 14, 2009 by Mike Szczys 33 Comments

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.

AC Shield Will Take Your Breath (heart Beat) Away.

December 10, 2009 by Mike Szczys 69 Comments

[Ryanjmclaughlin] came up with the idea of a Arduino shield that uses TRIACs to switch four channels of AC power. The forum thread he started delves into several interesting discussions covering what it would take to convert this for use with 240v power and of course, a debate about safety.

A reader named [Victor] sent this tip to us and mentioned that this shield might significantly reduce the number of Arduino related projects we see. That’s because mixing high voltage alternating current with delicate 5v logic circuitry can be a bad idea. We’re not saying the creator of this didn’t know what he’s doing, but if you don’t you could fry up your Arduino, or your body.
