Hasta La Gadget!

Laser tripwire security systems can be expensive propositions that don’t always work as planned — just ask Raytheon, which saw its $100 million Perimeter Intrusion Detection System for JFK International Airport undermined by one wayward jet skier. Taking that as a form of dare, Justin Huynh and teammates at Liquidware have devised a much cheaper (if also much smaller) tripwire of their own. Any interruption of a laser pointer’s beam is caught by an Arduino light sensor that promptly sends the alert to an Android-running BeagleBoard xM; if a toy like Bruce the shark dares cross the line, the BeagleBoard sends a Twitter message to let the authorities, or at least Huynh, clamp down on the trespasser. The invention won’t replace Raytheon’s handiwork anytime soon, although Huynh notes that additional or more powerful sensors could theoretically catch real, muscle-bound sharks and not just their plastic counterparts. The supply checklist and source code are waiting on the company’s project page below, so those who’d like to ward off miniature invasions can get started today.

We’ve already deconstructed Samsung’s Galaxy Note 10.1 on a metaphorical level, and now it’s iFixit’s turn to go the literal route. The DIY repair outlet found the pen-friendly tablet to be one of its easier tablet teardowns in recent memory: just about everything inside that frame can be swapped out individually. It’s even possible to replace the relatively cheap glass that sits on top of the considerably pricier LCD, just in case the slate plummets face-first but leaves some chance at salvaging its screen. While largely coming back with good news, the investigation also explains Samsung’s decision to go with a modest 7,000mAh battery — stuffing all those components into a 0.35-inch thick frame doesn’t leave much room for the lithium-ion pack that gives them life. Still, if you’re itching to understand what defines a truly repairable tablet, or just want to get a peek at those Galaxy S III-derived roots, the full surgical procedure is available at the source.

Extra-large phones often skew towards the, shall we say, pricey side. Micromax is keen to democratize this desire for the gigantic with the Superfone Canvas A100 (shown here on the left). A 5-inch LCD puts the Android 4.0 smartphone fully in phablet territory, but the inside is reasonable enough that those in the company’s native India won’t break the bank: an 854 x 480 resolution, 5-megapixel rear and VGA front cameras, a dual-core 1GHz processor, 4GB of built-in space and a microSD slot keep the dual-SIM phone down to Earth. Micromax also has us covered if we want a slightly more hand-portable size. The Superfone Pixel A90 touts a 4.3-inch, 800 x 480 Super AMOLED screen and brings in the added punch of an 8-megapixel rear camera on top of the A100’s baseline hardware. Either comes with the designer’s Siri-alike, AISHA, and should already be on Indian shelves with a slight twist in pricing — the bigger Canvas A100 is the more affordable of the two at a modest 9,999 rupees ($180) off-contract, while the A90’s slightly more exotic technology carries a 12,990-rupee ($234) price.

Motorola drew fresh respect after it vowed that its Android device customers could unlock their bootloaders, starting with the Photon Q LTE. Nearly everything about that process was kept in the dark, but it’s now been blown wide open: the company has posted a full page dedicated to the process. Getting started will demand the Android SDK, fastboot, new USB drivers and a slightly scary warranty release, but it otherwise goes through a very HTC-like process that provides an unlock key. Verizon subscribers who were hoping for a surprise Droid RAZR MAXX unlock won’t be happy, mind you; the Photon Q LTE is the only device on the list so far that isn’t already unchained as a matter of course. Motorola did characterize the unlock option as a forward-thinking option, which leaves us not so secretly wishing that high-profile future releases expand the list of unlockable devices a bit further.

We hope you didn’t think that Motorola would fight a purely defensive patent war against Apple after Google’s acquisition closed. Just days before a final ruling on its initial complaints, the RAZR maker has filed another dispute with the International Trade Commission that accuses Apple of violating patents through some iOS devices and Macs. Exact details of the dispute are under wraps for now; Motorola, as you’d imagine, only contends that it has no choice after Apple’s “unwillingness to work out a license.” While Apple hasn’t said anything about the subject, we already know how much it disagrees with Motorola’s previous licensing strategy — it’s unlikely Apple will just roll over, no matter what’s at stake.
