Laser tripwire does Hollywood-style security on the cheap, precious jewels not included

Sure, you could opt for a laser tripwire that puts intruders on blast via Twitter, but there’s something to be said for the simplicity of the latest security system to come from Instructables user EngineeringShock. You’ve seen this setup before: a group of mirrors are strategically positioned to bounce a laser beam across an open space, ensuring that even the most nimble of invaders — excepting MacGyver, perhaps — will set sirens blaring. Consisting of a programmable keypad, a laser and detector, a series of six carefully aligned mirrors, and an LED-equipped siren, the system does Hollywood-style security on a budget — the siren being the most expensive element at $20. If you’re looking to lock your stuff down like they do in the movies, follow the source link for full instructions, or check out the video demo after the break.

Skype for Android update adds US 3G calling, fixes personal data hole


Verizon Android users have had 3G Skype calling since this time last year, but the latest app release — v1.0.0.983 for those of you keeping tabs — brings 3G calling to the masses, without the need for a VZW-sanctioned app. The update also patches a rather significant security hole discovered last week, which could let third-party apps get hold of your personal information. We’re glad to see that’s no longer the case, and who’s going to object to free calling as part of the deal as well? Make sure your phone’s running Android 2.1 (2.2 for Galaxy S devices) and head on over to the Android Market to get updated.

redsn0w untethered jailbreak updated for iOS 4.3.2, still no love for iPad 2

Good news for all iOS jailbreakers: turns out the latest 4.3.2 update is still vulnerable to the same untethered hacking method used by redsn0w for 4.3.1, so Dev-Team’s @i0n1c simply had to port his code over to the new kernel to keep the jailbreak alive. As before, the almighty iPad 2 is still not supported here, and ultrasn0w unlockers are reminded to wait for the new PwnageTool release later this week; but the rest of you can go ahead and grab the new tool at the source link.

Update: Eke! Looks like the existing build is causing issues for iPhone owners — hang tight, we’re hearing that a fixed version is on the way!

Arduino geiger counter brings open source radiation detection to the geeky masses (video)

Need to detect radiation? We sure hope not — but if you’re looking for a straight-forward, altogether geeky geiger counter, the Libelium gang has your back. En route to the Tokyo Hackerspace as we speak (and believe us, they need it), the Radiation Sensor Board for Arduino is a low-cost alternative to existing devices. It’s available now either with a compatible geiger tube for €95 ($135) or without for €65 ($50). Hit up the source link to get started, but not before peeping the thing in action after the break. Is there anything you can’t do with Arduino?

Desire HD tries on Sensation’s Sense 3.0 suit, needs some tailoring for it to fit

So you got all excited after seeing HTC’s latest UI on the Sensation, but were dismayed to discover your hoary handset wouldn’t be getting the same Sense 3.0 love? As usual, the folks at xda-developers have just the tonic for what ails you… as long as you own a Desire HD. Yup, a clever fellow by the name of capychimp took the Sensation’s ROM and ported it to yesteryear’s HTC European flagship phone. The port isn’t perfect — those who dive in will lose camera support and the images need some resizing to properly fit on the HD’s 800 x 480 display — but brave souls who hit the source link for the download still get all those mellifluous movements that Sense 3.0 provides. See all the smooth scrolling in action after the break.

Update: XDA-developers have also given the HTC HD2 a quick Sense 3.0 hug, along with Android 2.3.3 in a similarly incomplete custom ROM.

ViewSonic G Tablet overclocked to 1.4GHz, goes on sale to celebrate

ViewSonic G Tablet overclocked to 1.4GHz, goes on sale to celebrate

The G Tablet hasn’t been getting much attention of late, slowly fading into obscurity as newer and fancier slates come floating on down the river. Now, thanks to XDA member pershoot, Viewsonic’s Tegra 2 tab has a little extra spring in its step. He’s managed to get it running at 1.4GHz (a 40 percent boost over stock) and, with the ability to run CyanogenMod 7, this 10.1-incher is definitely earning a reputation as something of a hacker’s delight. Now it’s even easier to afford, too, with Amazon knocking the price down to $280. Cheap and tweakable? Really, it doesn’t get any better than that.

Kinect-driven ‘Jellybean’ armchair hands-on (video)

Yes, this is what happens when you combine Kinect with a recliner on a motorized platform — perfectly normal people doing awesome zombie impersonations! This week at Microsoft’s MIX 11 web developer conference, the enterprising Clint Rutkas of Coding4Fun / Channel 9 fame showed off his Kinect-driven “Jellybean” armchair on stage during the keynote, and later let our very own Sean Hollister take it for a spin. Sadly, we missed our chance to capture this special occasion on video for posterity when the laptop used to control this armchair overlord ran out of juice in the final stages of our practice run. The motorized platform uses eight batteries, four omnidirectional wheels each with its own motor, and a pair of motor controllers connected to a laptop which interprets the input from Kinect (using the new SDK for Windows) and provides visual feedback to the driver. A gesture interface brings the entire contraption to life and even includes a hand signal to recline the armchair. Take a look at some closeup shots in our gallery below and watch our video of the recliner in action after the break.

Skype for Android vulnerable to hack that compromises personal info

If you didn’t already have enough potential app privacy leaks to worry about, here’s one more — Android Police discovered that Skype’s Android client leaves your personal data wide open to assault. The publication reports that the app has SQLite3 databases where all your info and chat logs are stored, and that Skype forgot to encrypt the files or enforce permissions, which seems to be a decision akin to leaving keys hanging out of the door.

Basically, that means a rogue app could grab all your data and phone home — an app much like Skypwned. That’s a test program Android Police built to prove the vulnerability exists, and boy, oh boy does it work — despite only asking for basic Android storage and phone permissions, it instantly displayed our full name, phone number, email addresses and a list of all our contacts without requiring so much as a username to figure it out. Android Police says Skype is investigating the issue now, but if you want to give the VoIP company an extra little push we’re sure it couldn’t hurt.

Sony Ericsson’s Android bootloader unlocking site goes live, modders rejoice

As promised, Sony Ericsson has just flipped the switch for its Android bootloader unlocking service, meaning those with an unbranded Xperia device from 2011 and onwards — Play, Arc, Neo, and Pro so far — will be able to try out custom ROMs and other dirty mods with ease. All that’s required here is your phone’s IMEI number, which in return gives you the unlocking key to go with the Android SDK’s fastboot program — all will be clear once you’ve read the instructions at the source link. But remember: SE does warn that this service may void your warranty if all goes pear-shaped, so just be careful, won’t ya?
