Tagged: Raspberry Pi, raspberry pi zero
The Raspberry Pi Zero is a new version that lowers the cost of gigahertz-class computing devices to just $5. It is based on a 1.0 GHz ARM11 core from Broadcom that is about 40% faster than the original Raspberry Pi. It also has 512MB of RAM, which is a lot for embedded or hobbyist applications. In fact, it doubles the original Raspberry Pi Model A (and is on part with the Model B). Storage is handled by a microSD card slot, as is the case with every previous Raspberry Pi except the Compute Module.
They also offer an alternative to the $5 price tag. If you pick up the print edition of MagPi magazine #40, which is the Christmas 2015 issue, you will receive a free Raspberry Pi Zero. The Raspberry Pi Foundation says that they printed 10,000 copies of this magazine. This is probably much more interesting than a CD-ROM demo of Battlezone II.
Due to high demand, I'm not sure when you can expect to get one though.

Western Digital recently made storage simpler when it comes to the Raspberry Pi micro computer. The aptly-named PiDrive Kit allows you to easily pair the company’s 1TB 2.5” hard drive with the SFF PC.
Released last week, the PiDrive Kit consists of a 1TB laptop-style mechanical hard drive, a custom Micro USB cable, a microSD card, and a 5V USB AC power adapter. The hard drive has a micro USB 3.0 port (though the Raspberry Pi only supports 2.0 speeds) for data and power. One end of the cable connects to the drive. The cable then breaks out into three cables which connect to one of the Pi’s USB ports, the Pi’s micro USB power input, and the USB wall adapter. This allows the drive and Raspberry Pi to be powered off of one USB connection.
Looking up the model number from the WD website, it looks like the hard drives are part of the company’s Passport Ultra line. The biggest bottleneck is likely to be the USB 2.0 interface, especially when it comes to burst speeds though. The included micro SD card (WD does not specify capacity or speeds) can be used to test out alternative operating systems or to test out setting up the external storage in Linux without messing with your main development install.
If you are using a Raspberry Pi Model B+ or a Pi 2 Model B and need a hefty terabyte of storage, WD has a simple option that is currently for sale on their website for $52. I’m sure enthusiasts will find uses for the massive storage upgrade beyond what micro SD can offer (at the moment).
Is it time to dust off the Pi?

With a Raspberry Pi and a cheap WiFi dongle a researcher has shown an effective way to completely block 2.4Ghz transmissions in a 120 metre radius. By disabling the backoff wait time, aka Short Interframe Space (SIFS), which is accomplished by firmware modification the WiFi dongle will continually resend a frame and block any device with a higher bitrate. This will block WiFI, Bluetooth and most IoT devices including security systems. They did not provide the source code used in this procedure, so you won't be able to block your friends for your own amusement but security researchers can reach out to the inventor for access to see if there are ways to circumvent this vulnerability. The story at The Register also has some information on TKIP vulnerabilities and possible ways to block transmissions on the 5GHz band.
"The wireless security boffin presented his work at the BruCon conference last week and revealed his weapon of choice is a bargain WiFi dongle bought off Amazon that, when paired with a Raspberry Pi and a small amplifier, can block 2.4Ghz transmissions for up to 120 metres."

The Raspberry Pi and its various flavours have been out for a while now and we have heard of a variety of projects developers and hobbyists have come up with but this story from The Register has them all beat. With a little Googling and a lot of creativity and inspiration there are kids out there creating all sorts of new uses for the little device. One 11 year old was a little worried about her Grampa and used a Pi along with PHP and HTML to pair a device with a webpage which can bring up a web browser for him, allow simple texting capabilities and to photos to make sure he is still OK. Others have created a scanner to keep track of scores in netball or to make sure that the sushi they grab from a restaurant's conveyor belt isn't getting too old. Give kids a chance to create and what they come up with will blow you away.
"Completely at home with Raspberry Pis, these kids Google around for the things they don’t know how to do - because when you’re 11, you don’t know what you can’t do. They are inventing the future, and for them it’s just child’s play."

Eltechs has been very successful at building emulators for the Raspberry Pi, until now focusing on the newer ARMv7 versions of the low cost systems. They have just finalized support for previous versions of the the Pi running ARMv6, reputedly at speeds almost matching the code running on native hardware. If you are developing on the Raspberry Pi or Pi 2 you should follow the links on the Slashdot article as there is currently a sale on the ExaGear Desktop software, $14.95 for the Pi 2 and $9.95 for the Pi.
"Russia-based Eltechs announced its ExaGear Desktop virtual machine last August, enabling Linux/ARMv7 SBCs and mini-PCs to run x86 software. That meant that users of the quad-core, Cortex-A7-based Raspberry Pi 2 Model B, could use it as well, although the software was not yet optimized for it. Now Eltechs has extended ExaGear to support earlier ARMv6 versions of the Raspberry Pi."

It did not take long to find a problem with the Raspberry Pi 2. As it turns out, the Pi 2 contains a power regulator chip that is susceptible to bright sources of light. The light will force electrons to move when a metal is struck by enough photons with the correct, per-photon energy, which is its frequency/color, and that will be perceived as a voltage (because it actually does cause a voltage).
In the Raspberry Pi 2, this manifests as a voltage drop and the device immediately powers down. This was first discovered by Peter Onion on the Raspberry Pi forums while he was taking photographs of his Raspberry Pi 2. He noticed that each time he snapped a photo, the Pi would shut down. Liz Upton of the Raspberry Pi Foundation promptly confirmed the issue and wrote a long blog post explaining what actually happens. She borrows Peter's joke from the forum thread, that the Pi 2 is camera shy, and explains that “everyday light sources” will not cause this to happen. She then explains the photoelectric effect, the role of the above pictured U16 chip, and the issue itself.
I definitely appreciate Liz Upton and the Raspberry Pi Foundation, founded on the premise of education, taking the time to explain their bugs from an educational standpoint. That said, it is easy to lose sight of your goal when you have a product to defend, and I am glad that it did not get in the way.
A final note: this will not damage the Pi 2, just cause it to crash and power down. The only real problem is that shutting down your device mid-task will crash your task. If that is a write to the SD card, that will likely corrupt that write.

Microsoft has announced that a version of Windows 10 will not only run on the Raspberry Pi 2, but that the OS will be available free of charge to members of its IoT (Internet of Things) developer program.
Microsoft made this announcement on their Dev Center website:
We’re excited to announce that we are expanding our Windows Developer Program for IoT by delivering a version of Windows 10 that supports Raspberry Pi 2. This release of Windows 10 will be free for the Maker community through the Windows Developer Program for IoT.
Windows 10 is the first step to an era of more personal computing. This vision framed our work on Windows 10, where we are moving Windows to a world that is more mobile, natural and grounded in trust. With the Windows for IoT developer program we're bringing our leading development tools, services and ecosystem to the Raspberry Pi community!
We see the Maker community as an amazing source of innovation for smart, connected devices that represent the very foundation for the next wave of computing, and we’re excited to be a part of this community.
We are excited about our partnership with the Raspberry Pi Foundation and delivering a version of Windows 10 that supports Raspberry Pi 2, and we will be sharing more details about our Windows 10 plans for IoT in the coming months.
For the last six months we've been working closely with Microsoft to bring the forthcoming Windows 10 to Raspberry Pi 2. Microsoft will have much more to share over the coming months. The Raspberry Pi 2-compatible version of Windows 10 will be available free of charge to makers.
Though Microsoft has effectively killed WinRT after revealing that it would not be upgraded to Windows 10, the support for the ARM-powered Pi demonstrates that the upcoming version of Windows still has more than just potential to run on ARM devices. This only makes sense considering the strategy of unifying Windows with a single version, and it is possible that the fork available for the Pi is more akin to mobile than to the desktop variant. Either way it sounds like it's worth the $35 to find out!

The Chromecast (and its open siblings) and the Raspberry Pi are interesting devices because they shrunk our concept of a compute device, which put them into new roles. Whether it is streaming media to your TV or controlling electronics on a high altitude balloon, you can use a full computer to do it. Full computers in new roles sound exactly like something Intel wants to research into lately.
The Intel Compute Stick, aptly named, seems to fit somewhere between these two devices. It is an HDMI dongle enclosing an x86, quad-core, computer with 2GB of RAM and 32GB of internal storage. Intel eventually plans to have the device powered by the HDMI port, but it currently requires power over micro USB. Besides power, it also has a standard USB (Type A-Female) port and a micro SD card slot. It also has 802.11n wireless networking inside it. Being a full Windows device, you can stream media, browse the web, and use many other applications on it.
The Intel Compute Stick with Windows will cost $149, which is significantly more than either a Chromecast or a Raspberry Pi. A Linux version, with 1GB of RAM (half of the Windows version) and 8GB of storage (a quarter of the Windows version), but at a significantly lower price of $89.

Tagged: usb computer, Raspberry Pi B+, Raspberry Pi, Education
The Raspberry Pi was intended as a learning device. David Braben, previously known for Rollercoaster Tycoon and other video games, noticed that computer science education was lacking and he wanted to contribute to its advancement with a cheap, portable, and highly-programmable PC. Yesterday, the organization announced a new model, the Raspberry Pi A+, which is (theoretically) cheaper, smaller, and has a few better components. This announcement follows the release of the Raspberry Pi B+ from last July.
I say “theoretically cheaper” because, although the organization is touting a price reduction from $25 to $20 USD, that always depends on the reseller. MCM Electronics, one of the foundation's US-based distributors, is selling the A+ for its list price of $20 (plus an extra ~$10 in shipping, before tax). In the UK, however, the currency conversion works out to about $25 before VAT. That said, the UK is known to be expensive for electronics.
Whatever the price, the device is slightly improved. While it keeps the same, Broadcom BCM2835 SoC and RAM, the memory has been upgraded to a locking MicroSD card slot, the audio's power delivery has been improved to reduce noise, and the number of GPIO pins has been increased from 26 to 40. The latter enhancement will allow the Pi to interface with more, and different, sensors and motors for robotics and other embedded applications.
The Raspberry Pi A+ and B+ are both currently on backorder for $20 and $35, respectively, before a $10 shipping fee and any applicable taxes.
