Google AirShow streams Google I/O live from several RC blimps (hands-on video)

Yes, there's a fleet of camera-equipped, remote-controlled blimps live-streaming a bird's-eye view of Google I/O on YouTube, right now. It's called Google AirShow and it's taken over the airspace within Moscone Center. We briefly chatted with Chris Miller, a software engineer with AKQA (the company that put the dirigibles together for Google), about the technology used in each aircraft. It all begins with an off-the-shelf model airship that's flown manually via standard a 2.4GHz radio. Each blimp is outfitted with a servo-controlled USB camera and 5GHz USB WiFi dongle which are both connected to a Raspberry Pi board running Debian, VLC and Python. A custom-designed Li-polymer battery system powers the on-board electronics. The webcam encodes video as motion-JPEG (720p, 30fps) and VLC generates a YouTube-compatible RTSP stream that's broadcast over WiFi. Python's used to pan the servo-controlled camera via the Raspberry Pi's PWM output. The result is pretty awesome. But don't just take our word for it -- check out the gallery and source link below, then watch our hands-on video after the break.

Screen Grabs: Raspberry Pi survives electronics blackout for a cameo on Revolution

Screen Grabs chronicles the uses (and misuses) of real-world gadgets in today's movies and TV. Send in your sightings (with screen grab!) to screengrabs at engadget dot com.

The original premise of NBC's show Revolution is that in the near future some unknown worldwide catastrophe devastated all electronic devices, plunging everyone into a blackout. As the plot has progressed however, in limited cases the power is coming back on. That includes a nanotech machine a couple of characters are planning to use to perform emergency surgery -- by shoving what appears to be a USB stick into an open wound -- and its configuration is enabled thanks to a very familiar-looking $35 device. Keen eyed viewers spotted a Raspberry Pi (top center) as it popped on screen a few times, however like our own prime time cameo it flashes by very quickly, the screencap above may be your best look at it.

Raspberry Pi camera module comes to the UK May 14th, lands early for some (updated)

Remember that Raspberry Pi camera module we wrote about a few months ago? It looks like UK-based electronics retailer CPC / Farnell will start taking orders for the shooter on May 14th. Users on the Raspberry Pi forums who signed up for info about the camera module have received an email from the retailer inviting them to order. As a reminder, the five megapixel fixed-focus shooter -- which only measures 25 x 20 x 9mm -- can snap 2,592 x 1,944-pixel images and capture video at 1,080p (30fps), 720p (60fps) and VGA (60 or 90fps). While the accessory is expected to cost about $25, there's no actual pricing details on CPC / Farnell's website. Wanna see the camera module in action? One lucky Raspberry Pi user's received the device early and shared a video -- check it out after the break.

Update: As promised, the boards are now officially available to order per a blog post on the Raspberry Pi website. And the price is indeed $25. Hit the source link for a list of commands needed to activate the add-on, or check after the break for another video demonstrating the setup process and some PR explaining Element 14's competition to promote the Pi and its camera.
