A telling quote to describe the Arduino community can be found in MAKE:Blog's talk with Intel CEO Brian Krzanich who relates a conversation with a developer who preferred to use Arduino boards for prototyping even when offered Intel boards for free. Today Intel has officially joined the Arduino team with the release of the Galileo which features a new 400MHz Intel Quark SoC with 256 MB of DRAM and Mini-PCIe slot, 100Mb Ethernet port, Micro SD slot, RS-232, and USB host and client ports for interfacing with the device. That puts it on even footing with the popular Raspberry Pi but with the ability to use Arduino shields and a mini-PCIe slot to open up some new possibilities which you will likely be reading about on Hack a Day after it is released.
That was not the only interesting bit of Arduino news out of the Maker Faire, Texas Instruments is also releasing the TRE which is essentially two Arduinos in one. The 1GHz Sitara AM335x processor is described as performing 100 times better than either the Arduino Leonardo or Uno and there is also a full AVR based Arduino present on the board to help process some tasks and to offer a more familiar environment to start playing with the Sitara from. According to The Inquirer you will be able to pick up a TRE sometime in the spring of next year.
"Krzanich’s own interest in Arduino was piqued when an outside developer told him about his product development project, and Krzanich asked him why he was using Arduino instead of an Intel board. Even when Kryzanich offered to make Intel products available to him at low cost or no cost, the developer said he valued the Maker community and the Arduino platform and he wasn’t willing to switch. Members of Krzanich’s team reached out to Massimo Banzi and they forged a partnership to develop the Galileo board and work together on future projects. Banzi said that he’s glad to have more resources and the scale of Intel to help the Arduino platform continue to develop new capabilities and reach new audiences."

Over the past few weeks, I have been developing a device that enables external control of Wirecast and XSplit. Here's a video of the device in action:
But now, let's get into the a little bit of background information:
While the TriCaster from NewTek has made great strides in decreasing the cost of video switching hardware, and can be credited with some of the rapid expansion of live streaming on the Internet, it still requires an initial investment of about $20,000 on the entry-level. Even though this is down from around 5x or 10x the cost just a few years ago for professional-grade hardware, a significant startup cost is still presented.
This brings us to my day job. For the past 4 years I have worked here at PC Perspective. My job began as an intern helping to develop video content, but quickly expanded from there. Several years ago, we decided to make the jump to live content, and started investing in the required infrastructure. Since we obviously didn't need to worry about the availability of PC Hardware, we decided to go with the software video switching route, as opposed to dedicated hardware like the TriCaster. At the time, we started experimenting with Wirecast and bought a few Blackmagic Intensity Pro HDMI capture cards for our Canon Vixia HV30 cameras. Overall, building an 6 core computer (Core i7-980x in those days) with 3 capture cards resulted in an investment of about $2500.
Advantages to the software route not only consisted of a much cheaper initial investment, we had an operation running for about a 1/10th of the cost of a TriCaster, but ultimately our setup was more expandable. If we had gone with a TriCaster we would have a fixed number of inputs, but in this configuration we could add more inputs on the fly as long as we had available I/O on our computer.

You can buy the USB Infrared Toy v2 from Dangerous Prototypes and get right to turning cheaply made IR devices off and on but you would miss out on a chance to build one yourself. If you follow the links from Slashdot you will get a quick tutorial on how to determine the oscillation frequency of a broadcaster by looking at the components of the circuit and how to use an Arduino UNO to create your own. If you are already familiar with this type of project consider teaching someone who needs their fear of electronic devices reduced through understanding how these magic boxes work.
"Cheap home alarms, door opening systems and wireless mains switches can be bypassed with low-cost and home-made devices that can replicate their infrared signals. Fixed-code radio frequency systems could be attacked using a $20 'toy', or using basic DIY componentry."

Tagged: arduino, hack, sd card
It would seem that there is more than one way to access an SD Card, and the usual interface used by your devices called SDIO can be the failure point preventing you from accessing your data. The alternative method is called SPI mode which is significantly slower but also less complex which means that when SDIO fails you may still be able to access and copy your data using SPI mode. Over at Hack a Day you can read about how to use a Playduino One Arduino clone and a SD card shield along with some custom Python scripts to recover those vacation snaps.
"A few days ago, one of [Severin]‘s SD cards died on him, Instead of trashing the card, he decided to investigate what was actually wrong with the card and ended up recovering most of the data using an Arduino and an immense amount of cleverness."

During Google IO, Google announced for their Android cell phone operating system a new Open Accessory API. This API is currently supported on Android 2.3.4 and 3.1 (Honeycomb) for cell phones and tablets respectively. This Open Accessory API is a "complete solution" of hardware and software for an Android ADK (Android Accessory Development Kit). On the hardware side of things, Google's reference design uses an Arduino board as well as USB host circuitry from Circuits@Home. using the Google ADK or Open Accessory compatible boards from Microchip and RT Corporation compatible boards, developers are able to offer hardware accessories that are able to communicate over USB (and Bluetooth in the future) to software applications.
The interesting part about Open Accessory is that when first plugging an Android phone into an Open Accessory piece of hardware, the hardware is able to indicate to the phone what software applications it needs in order to interact with and be controlled by the phone.
According to Hugo Barra, “with the ADK, we are welcoming hardware developers into the Android community, and giving a path to building great Android accessories quickly and easily.” He emphasises that the openness of Android Open Accessory means that there are no NDAs, no licensing fees, and no approval process in building the hardware or accompanying software.
Along with the ADK comes Android@Home, which is a new open wireless protocol that will allow "every appliance in your home" to communicate with your android phone.
Google wants to ramp up the imaginations of developers, and encourage them to develop new methods of notification systems and more immersive game-play. Much as the popular Parrot AR.Drone has augmented reality gaming aspects, Google wants to encourage game developers to utilize Android@Home to make their games more immersive by using the environment. During the IO presentation, they demonstrated flickering lights while playing Quake which reacted to gunfire in the game.
By choosing to go open source for not only the software but the hardware behind the Android Open Accessory API, they will enable as many people with as many ideas as possible to have a chance to develop accessories for the Android platform. This freedom of imagination will encourage innovation, and in a competitive OS market, innovation is good for the consumer.
