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.

This is just a quick note for a small subset of our audience. If any of our developer-minded readers are in the Phoenix, Arizona region on February 19th, Intel will be hosting a meetup at UAT (the University of Advancing Technology). The processor vendor will perform a technical presentation about the Edison Internet-of-Things (IoT) developer kit. Shortly after the presentation, the group will move to Aunt Chilada's for a social event.
The presentation will take place in the theatre (there is only one as far as I can tell) at 6:30pm. Admission is free and there will be 10 Intel Edison kits to be raffled. Food and beverages will be provided by Intel (at Aunt Chilada's restaurant).
Microsoft Filed for "Windows 365" Trademark in Late January. Jeremy Prepares to File for Windows 340 through 364?

While it is trivial for a large corporation to file for a trademark, there are fairly strict guidelines with how they are used (or, more accurately, not-used). Because trademarks can be forever, the law outlines numerous procedures that can classify them as abandoned, which lets Coca Cola be a known, legitimate source of Coca Cola for as long as Coca Cola makes Coca Cola, while preventing businesses from being created that do nothing but license names.
Patents! I'm looking at you!
So the news is that Microsoft filed for the trademark, “Windows 365”. Knowing their trademark on Office 365, people are assuming that this will lead to a subscription version of Windows. The trademark filing is then compared to the statements made by Terry Myerson about Windows as a Service and the free upgrade from Windows 7 and Windows 8.x for a year. You can see where this is headed.
But I have another idea. Perhaps this is intended to lead into their not-yet-disclosed enterprise licensing arrangement for Windows 10 (and related services)? Despite its consumer sound, Office 365 seems to have a fairly large adoption rate with business and education customers. As an example, which is not statistically relevant but is still interesting, the local public school board where I live has licensed a non-commercial, 5-PC license for every staff and student in their organization. This concept has a lot of potential for those customers.
If, of course, they give us a per-device and system builder license option, too.

After the great experience Phoronix had setting up the X1 Carbon with both Fedora and Ubuntu, they purchased a new Broadwell based NUC to experiment with. This model uses the Core i3 5010U with an onboard 900MHz HD Graphics 5500, support for 2 DIMMs of up to 64GB of DDR3-1866, an M.2 SSD card and a 2.5" HDD or SSD. Intel has stated that Ubuntu, Linux Mint, Fedora, and openSUSE will all be compatible so Phoronix has a bit of testing ahead of them. There are no benchmarks as of yet but you can see their teardown of this new NUC here.
"With wrapping up my Core i7 5600U Broadwell Linux tests using the new ThinkPad X1 Carbon in the next few days, fortunately the Intel BOXNUC5I3RYH just arrived as the first available NUC Kit shipping with a Broadwell processor. The NUC5i3RYH features a Broadwell Core i3 processor, HD Graphics 5500, and support for a M.2 SSD card and 2.5-inch HDD/SSD."

SFF PCs get an upgrade
Ultra compact computers, otherwise known as small form factor PCs, are a rapidly increasing market as consumers realize that, for nearly all purposes other than gaming and video editing, Ultrabook-class hardware is "fast enough". I know that some of our readers will debate that fact, and we welcome the discussion, but as CPU architectures continue to improve in both performance and efficiency, you will be able to combine higher performance into smaller spaces. The Gigabyte BRIX platform is the exact result that you expect to see with that combination.
Previously, we have seen several other Gigabyte BRIX devices including our first desktop interaction with Iris Pro graphics, the BRIX Pro. Unfortunately though, that unit was plagued by noise issues - the small fan spun pretty fast to cool a 65 watt processor. For a small computer that would likely sit on top of your desk, that's a significant drawback.
Intel Ivy Bridge NUC, Gigabyte BRIX S Broadwell, Gigabyte BRIX Pro Haswell
This time around, Gigabyte is using the new Broadwell-U architecture in the Core i7-5500U and its significantly lower, 15 watt TDP. That does come with some specification concessions though, including a dual-core CPU instead of a quad-core CPU and a peak Turbo clock rate that is 900 MHz lower. Comparing the Broadwell BRIX S to the more relevant previous generation based on Haswell, we get essentially the same clock speed, a similar TDP, but also an improved core architecture.
Today we are going to look at the new Gigabyte BRIX S featuring the Core i7-5500U and an NFC chip for some interesting interactions. The "S" designates that this model could support a full size 2.5-in hard drive in addition to the mSATA port.

Tagged: razer blade, razer, nvidia, Intel, GTX 970M
When the Razer Blade launched, it took a classy design and filled it with high-end gaming components. Its competitors in the gaming space were often desktop replacements, which were powerful but not comfortable, every-day laptops. The Blade also came with a $2800 (at the time) price-tag, and that stunted a lot of reviews. It has been refreshed a few times since then, including today.
The New Razer Blade QHD+ has a 14-inch 3200x1800 display, with multi-touch and an LED backlight. The panel is IGZO, which is a competitor to IPS for screens with a high number of pixels per inch (such as the 4K PQ321Q from ASUS). This is housed in a milled aluminum chassis that is about 7/10th of an inch thick.
Its power brick is rated at 150W, which is surprisingly high for a laptop. I am wondering how much of that electricity is headroom for fast-charging (versus higher performance when not on battery). Most power adapters for common laptops that I've seen are between 60W and 95W. In a small, yet meticulously designed chassis, I would have to assume that thermal headroom of either the heatsinks or the components themselves would be the limiting factor.
On the topic of specifications, they are expectedly high-end.
The GPU was upgraded to the GeForce GTX 970M with 3GB of VRAM (up from a 3GB 870M) and the CPU is now a Core i7-4720HQ (up from a Core i7-4702HQ). The system memory also got doubled, to 16GB (up from 8GB). It also has 3 USB 3.0 ports, HDMI 1.4a out, 802.11a/b/g/n/ac, Bluetooth 4.0, and (of course) a high-end, backlit keyboard. Razer offers a choice in M.2 SSD capacity: 128GB for $2199.99, 256GB for $2399.99, or 512GB for $2699.99. This is kind-of expensive for solid state memory, $1.56/GB for the jump to 256GB and $1.17/GB to go from there to 512GB.
The New Razer Blade Gaming Laptop is available now at Razerzone.com in the US, Canada, Singapore, and Hong Kong. It will arrive at Microsoft Stores in the USA on February 16th. China, Australia, New Zealand, Malaysia, UAE, Japan, Korea, Taiwan, and Russia can purchase it on Razerzone.com in March. Prices start (as stated above) at $2199.99.

ASRock has unleashed an update to its small form factor VisionX series. The new VisionX 471D adds a faster Haswell processor and dedicated Radeon mobile graphics to the mini PC.
The 7.9” x 7.9” x 2.8” PC chassis comes in black or silver with rounded corners. External I/O is quite expansive with a DVD optical drive, two audio jacks, one USB 3.0 port, one MHSL* port (MHL compatible port that carries both data and video), and a SD card reader on the front. Further, the back of the PC holds the following ports:
- 5 x Analog audio jacks
- 1 x Optical audio out
- 1 x DVI
- 1 x HDMI
- 1 x Gigabit Ethernet jack
- 802.11ac (2 antennas)
- 5 x USB 3.0
- 1 x USB 2.0
- 1 x eSATA
ASRock has gone with the Intel Core i7-4712MQ processor. This is a 37W Haswell quad core (with eight threads) clocked at up to 3.3GHz. Graphics are handled by the AMD Radeon R9 M270X which is a mobile “Venus” GCN-based GPU with 1GB of memory. The 28nm GPU with 640 cores, 40 TMUs, and 16 ROPs is clocked at 725 MHz base and up to 775 MHz boost. The PC further supports two SO-DIMMS, two 2.5” drives, one mSATA connector, and the above-mentioned DVD drive (DL-8A4SH-01 comes pre-installed).
The VisionX 471D is a “barebones” system where you will have to provide your own OS but does come with bundled storage and memory. Specifically, for $999, the SFF computer comes with 8GB of DDR3 memory, a 2TB mechanical hard drive, and a 256GB mSATA SSD (the ASint SSDMSK256G-M1 using a JMF667 controller and 64GB 20nm IMFT NAND). This leaves room for one additional 2.5” drive for expansion. Although it comes without an operating system, it does ship with a Windows Media Center compatible remote.
This latest addition to the VisionX series succeeds the 420D and features a faster processor. At the time of this writing, the PC is not available for purchase, but it is in the hands of reviewers (such as this review from AnandTech) and will be coming soon to retailers for $999 USD.
The price is on the steep side especially compared to some other recent tiny PCs, but you are getting a top end mobile Haswell chip and good I/O for a small system with enough hardware to possibly be "enough" PC for many people (or at least a second PC or a HTPC in the living room).

Tagged: nuc, fitlet-x, fitlet-i, fitlet-b, fitlet, compulab, APU, amd
The Israeli PC manufacturer, CompuLab Ltd., has announced three lines of small, fanless systems. They will be smaller than the NUC and run AMD APUs, from the E1 to the A4, which CompuLab claims are more powerful than NUCs of comparable prices. They can be configured with either Windows (7, 8, or 10) or Linux Mint. They are officially classified as Industrial PCs, and the 5-year warranty reinforces that association, but others might also be interested.
Let's start in the middle with the Fitlet-i. With a TDP of 4.5W, it is powered by an AMD A4-6400T APU at 1.0 GHz (1.6 GHz boost). It can be configured with up to 8GB of DDR3 memory.
The other features of the Fitlet-i are:
- Two 3.5mm stereo audio jacks (one in, one out)
- One S/PDIF port
- Four USB 2.0 ports
- Two USB 3.0 ports
- Two HDMI 1.4 ports
- Two Gigabit Ethernet ports
- 802.11ac (clarified Jan 17th: built in, with external antennas I believe)
- One microSD card slot
- One eSATA port, rated at 6Gbps
- One serial port (because industrial)
- One mSATA socket (low profile)
- One mini-PCIe socket (high profile, half or full size)
The Fitlet-X is similar to the above, except that it has four Gigabit Ethernet ports (instead of two), but it loses one USB 2.0 port (three total), has its Wireless downgraded to a USB 802.11n dongle, and it has no eSATA port. The extra pair of Gigabit Ethernet adapters is not the only perk though, as it has their “FACET card” interface, which provides 3 lanes of PCIe (if you want to take a risk on the interface).
That leaves us with the Fitlet-b, which is the base model. Its TDP is slightly lower, 3.95W, and is powered by an AMD E1-6200T APU at 1.0 GHz (1.4 GHz boost). It has just one Gigabit Ethernet port, two USB 3.0 ports, three USB 2.0 ports, the USB 802.11n dongle, and just a full-size mSATA (low profile) expansion for storage. It does have both HDMI 1.4a outputs though.
The Fitlet will be available in February, starting at $129 for the Fitlet-b barebone, via Amazon for North America and Europe. It will also be available directly from CompuLab and resellers for the rest of the world.
Introduction, Specs, and First Impressions
In our review of the original LIVA mini-PC we found it to be an interesting product, but it was difficult to identify a specific use-case for it; a common problem with the mini-PC market. Could the tiny Windows-capable machine be a real desktop replacement? That first LIVA just wasn't there yet. The Intel Bay Trail-M SoC was outmatched when playing 1080p Flash video content and system performance was a little sluggish overall in Windows 8.1, which wasn't aided by the limitation of 2GB RAM. (Performance was better overall with Ubuntu.) The price made it tempting but it was too underpowered as one's only PC - though a capable machine for many tasks.
Fast forward to today, when the updated version has arrived on my desk. The updated LIVA has a cool new name - the “X” - and the mini computer's case has more style than before (very important!). Perhaps more importantly, the X boasts upgraded internals as well. Could this new LIVA be the one to replace a desktop for productivity and multimedia? Is this the moment we see the mini-PC come into its own? There’s only one way to find out. But first, I have to take it out of the box.
Chipset: Intel® Bay Trail-M/Bay Trail-I SOC
Memory: DDR3L 2GB/4GB
Expansion Slot: 1 x mSATA for SSD
Storage: eMMC 64GB/32GB
Audio: HD Audio Subsystem by Realtek ALC283
LAN: Realtek RTL8111G Gigabit Fast Ethernet Controller
USB: 1 x USB3.0 Port, 2 x USB2.0 Ports
Video Output: 1 x HDMI Port, 1 x VGA Port
Wireless: WiFi 802.11 b/g/n & Bluetooth 4.0
PCB Size: 115 x 75 mm
Dimension: 135 x 83 x 40 mm
VESA Support: 75mm / 100mm
Adapter Input: AC 100-240V, Output: DC 12V / 3A
OS Support: Linux based OS, Windows 7 (via mSATA SSD) Windows 8/8.1
Thanks to ECS for providing the LIVA X for review!
Packaging and Contents
The LIVA X arrives in a smaller box than its predecessor, and one with a satin finish cuz it's extra fancy.

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.
