The guys over at Olimex Ltd have created one of the smallest and most efficient models on the market. Their Arduino separates into three pieces and is designed to plug right into a breadboard. Their design is completely revolutionary and their product is ingenuous. For more information see the link below.


Nook Simple Touch hacked into an Android Tablet


With the release of the last Harry Potter movie (Deathly Hallows Part Two) there were several parties going on at local businesses. My brother participated in one of these parties and took 2nd place for his costume. His prize, a Nook Simple Touch. If you’ve ever played with one of these e-readers you would know how limited their functionality is. The home screen shows your recent books you’ve read and has a link to the online store. He had no need for it, being a 7 year old, and it was given to me. After reading a few books on it, I cast it aside thinking I would never find an actual use for it.

But recently that thought changed, I read an article on someone who put Android operating system onto their Nook Simple Touch. I was ecstatic that I finally had a use for this junky e-reader. Using a Micro SD card and Touchnooter, a boot loader found online, I was able to install and run the Android OS on the Nook ST. The screen refresh is almost unbearable to work with, but using a NO REFRESH hack I was able to work around that. I will post a video soon with a demonstration on the Nook ST Android tablet.  I am currently able to run the Android app store and install .apk files from there, and use Opera Mobile as an internet browser. If you are “fortunate” enough to have one of these tablets I strongly recommend looking up Touchnooter and attempting to hack your own e-reader. I keep mine in my tool bag and use it as an emergency hacker tablet. It is able to communicate with Arduino the same way an android phone would, though i’m not sure what use it would really have. For now, I will use mine as a virtual file folder and GBC emulator. Let me know what you think with a comment below.

Sneak Peak at the Arduino TRE


Partnering with TI, (Texas Instruments)  Arduino has created the most powerful model to date. The Arduino TRE. This is the first Arduino able to run “Full Linux”, meaning that users will be able to run desktop applications and high speed communication. Due to the new 1-GHz Sitara AM335x processor users will get up to 100 times more performance out of the TRE then the Leonardo or the UNO. IN a recent post on Arduino blog, Author Zoe Romano says…

In addition, the Arduino TRE is partially the result of a close collaboration between Arduino and the foundation. These open hardware pioneers share a passion for expanding open source development and making technology accessible for artists, designers and hobbyists. The TRE design builds upon the experience of both Arduino and BeagleBoard, combining the benefits of both community based boards.

So look forward to more information on Arduino’s new micrcontroller, it is scheduled to be available Spring 2014, but you can see it live at Maker Faire Rome.

Inside the Arduino Yún



The Arduino Yún is the newest member to the Arduino line up and is in a class all its own.  The Overview from…

The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the AtherosAR9331. The Atheros processor supports a Linux distribution based on OpenWRT named Linino. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.

The Yún distinguishes itself from other microcontrollers with its ability to communicate with the Linux distribution onboard. This feature allows users to easily interact with their Yún using Python script and shell in onboard.  Below are more detailed specs on the Arduino Yún.
