    Raspberry Pi founder demonstrates upcoming touch panel accessory, Pi tablets a possibility

    Raspberry Pi owners will soon be able to ditch their phablets, iPads and Android-powered slates. Why, you ask? Because they’ll be able to build their very own “Pi Pads” using a brand-new accessory for the credit card-sized computer.
    During a recent interview at TechCrunch Disrupt in London, Raspberry Pi founder Eben Upton said his foundation has been promising fans that a display accessory was coming – and now it’s finally going to happen.

    The first official display from the Raspberry Pi Foundation is a 7-inch VGA capacitive touch panel with a mount for a Raspberry Pi board on the reverse. Upton said it’s kind of like a tablet, if you’re prepared to put up with a very thick tablet. The idea, he added, is that it gives users something they can embed.
    Upton said they hope to make the display available by the end of the year or early next year. Pricing wasn’t mentioned although given the nature of the computer that’ll be driving it, I wouldn’t expect it to be too terribly expensive.
    In related news, Upton said they plan to make an announcement soon regarding a Raspberry Pi model A+. He didn’t divulge any information on the board outside of saying he thinks it’s going to be an exciting product.
    The Raspberry Pi Foundation has sold more than four million mini computers since offering its first board nearly three years ago. That’s quite the accomplishment when you consider Upton envisioned selling roughly 10,000 units. Ever.

    Rapsbery PI A+ chega a $20

    [QUOTE] There's a new Raspberry Pi, and it's smaller, more efficient, and cheaper than ever before.

    Today, the Raspberry Pi foundation launched its Raspberry Pi Model A+, a tiny computer that has a footprint smaller than a credit card. It measures just 55 x 65 mm.
    The Model A+ uses the same 700 MHz BCM2835 processor as found previously in earlier Raspberry Pis, and it comes with 256 MB of memory. It has a single USB port (with support for USB hubs), an HDMI interface, a push-push Micro-SD card slot, and a dedicated low-noise audio solution.
    It also has a 40-pin GPIO interface for expansion cards, making it compatible with Raspberry Pi HATs add-on boards. Also on the board are camera and display adapters, and it is powered by a single micro-USB interface.
    The removal of the network interface, along with a revised board design, has resulted in significantly lower power consumption, making the Model A+ ideally suited for low-power battery operated applications.

    It should be noted that while the Model A+ features many of the improvements that the B+ also received, it's not built to replace that model but rather to work as a lower-cost, smaller, and more efficient unit that can be used for different applications. [

    Astro Pi: Raspberry Pi computers to voyage into space

    The humble Raspberry Pi computer has been used in what already seems to be an amazingly broad range of gadgets. Developers keep on surprising us with the devices and applications they can cook up with the mini computing marvel. Today you can add two more interesting and diverse RasPi projects to that list; the Astro Pi and the Pitendo.
    Pis in space
    Primary and secondary school children have been invited to design apps for the Raspberry Pi, to be run in space. British ESA Astronaut Tim Peake will take Two Raspberry Pi computers to the International Space Station (ISS) as part of his 6 month mission. The Raspberry Pi blog says that both Pis will be connected to a new 'Astro Pi' board, loaded with a host of sensors and gadgets. The Pis will run the winning apps code, collect the programmed data readings and then the data will be downloaded to Earth for the winning teams.

    The competition opened yesterday and the winning code will be loaded into the Raspberry Pis in orbit early next year. The school students will "devise and describe an original idea for an experiment or application which can be conducted on the Astro Pi". The two best submissions will be implemented by RasPi programmers and a class-set of these mini computers given as a prize to both winners. The top 50 entrants in each KS3, 4 and 5 category will also win their own Raspberry Pi computer and an Astro Pi sensor board (as seen in the picture below).

    The Astro Pi will include the following:

    • Gyroscope, accelerometer and magnetometer sensor
    • Temperature sensor
    • Barometric pressure sensor
    • Humidity sensor
    • Real time clock with backup battery
    • 8×8 RGB LED display
    • Several push buttons
    • Camera module/ IR camera module

    Pitendo console
    This is a pocket sized version of the classic NES games console. Compared to the ambitious project above this might seem a little trivial, but it will definitely appeal to some retro gaming fans. The core of the system is, of course, a Raspberry Pi (B+) and it is available as a complete kit.

    The Pitendo Ultimate kit costs $119 including the Raspberry Pi Model B+, a Pitendo case, an SD card pre-loaded with RetroPie (but no ROMS included of course), a SNES layout controller, wall wart power supply and an HDMI cable. That's everything you need except for the games. However if you already have a RasPi in your drawer, and perhaps several other of the bits above like a gamepad, power adaptor and HDMI cable, the Pitendo case is available on its own for $49.

    Miguel the Electric Eel Uses Raspberry Pi to Tweet

    An electric eel at Tennessee Aquarium has been tweeting from his tank, thanks to a modified Raspberry Pi. The eel, named Miguel Wattson, triggers tweets whenever he expels an electrical discharge. The charge is detected by sensors hooked up to a Raspberry Pi, which triggers a tweet – purporting to be from Miguel, but written by the aquarium’s team – to the eel’s Twitter account, @EelectricMiguel.




    “In the wild, Electric Eels use their voltage to navigate, stun prey and as a defense mechanism,” said Brad Thompson from the Tennessee Aquarium. “They have complete control of their discharges varying the amount of energy released to meet their needs.”
    The project was set up in conjunction with the Tennessee Tech University’s Business Media Center. “This was a really fun project for our multi-disciplinary team,” Kevin Liska, director of the Business Media Center, said. “They combined electrical engineering and emerging business communication to give the eel a voice.”

    Raspberry Pi kicks up a notch



    New BCM2836 chip

    The new Raspberry Pi 2 model B is out and, thanks to a new BCM2836 chip, is heading towards becoming jolly useful.

    The Broadcom CPU has quadrupled the cores so that each run at 900 MHz. The previous model had a single-core 700 MHz. Raspberry Pi has included a small tweak that allowed them to support 1 GB of RAM which is double the 512 MB on the other models. More RAM equals more space for apps to run in.
    Raspberry Pi Foundation head Eben Upton says that the changes make the new model usable as a PC. The Raspberry Pi 2 model B is otherwise the same as the current B+, which is good for those worried about transitioning.
    The price will also be the same $35 that made Raspberry Pi a name in the industryWhen the Raspberry Model 2 becomes available, there will be as much as 100,000 units immediately ready to prevent the kind of backlog that it experienced in the past.
    Raspberry Pi will continue to sell its B+. The logic is that there will be many who prefer to keep the same hardware.

    Microsoft vowes to support the Rasberry Pi 2 - offering up Windows 10

    Unsure if the Rasberry Pi 2 is for you? Microsoft are putting their might behind this latest product offering - announcing that it's "delivering a version of Windows 10 that supports Raspberry Pi 2."


    The 2nd generation of Rasberry Pi offers a more powerful processor and twice as much RAM. Often toted by retro-game emulators worldwide as an optimum product, you could always install versions of Windows on the device, however Microsoft is now working to directly offer up an Operating System tailored for this tiny computer system.

    There will be more information released later as to how exactly Microsoft will be supporting the Rasberry Pi 2, with them stating this will come "in the coming months."

    Set to retail for $35 and now with a specially-tailored Windows 10 offering - you can likely sort yourself out a fully-functional home computer for a tiny price.

    Interested in seeing what the Rasberry Pi 2 looks like? Look below!

    Raspberry Pi 2 Crippled By Xenon Camera Flash 'Death Ray'

    As we discovered at the start of the month, the Raspberry Pi 2 brings a lot of good stuff to the table. We're talking double the RAM, a quad-core processor, Windows 10 support - it's all great stuff. But one thing we didn't realize it also introduced was a bizarre flaw that's been dubbed "XENON DEATH FLASH".
    You see, if your camera happens to have a Xenon flash, taking a picture of the RPi 2 while it's operational might cause it to lock up, or power off. It sounds ridiculous, but it's true. After user PeterO asked on the official RPi forums about why the latest model is so "camera-shy", others eventually jumped in with their confirmations.
    image: http://hothardware.com/ContentImages...pberryPi_2.jpg
    As you might expect, it took very little time before YouTube videos showcasing the issue popped-up.






    Considering the fact that others were able to confirm this issue so quickly, it doesn't seem like this issue would affect just a small number of second-gen RPi units. Some chip - likely the SoC - seems to be lacking shielding, and in some cases, even covering it up with light reflective material doesn't help. In one case, the issue would go away if the unit was turned upside-down.
    It's hard to gauge at this time just how much of a problem this issue is. If the only gotcha is that you can't take a photo using a Xenon-based flash, that's not so bad. But I do wonder if what causes this to be an issue could cause further issues down the road. That wouldn't be a great thing for the Raspberry Pi Foundation to have to deal with, especially as these units are sold so cheaply to begin with.

    Xenon Flashes Make a Case for a Raspberry Pi 2 Case

    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.
