DIY'er Steve Hoefer used a piezo speaker, a tiny gear reduction motor, an Arduino, and a PVC pipe to make his secret-knock door lock.
(Credit: Steve Hoefer)I've been hearing more and more about the Arduino microcontroller project lately, and this is by far one of the coolest uses for it I've seen. Arduino is an open-source hardware project meant for easy prototyping of hardware ideas. This is Steve Hoefer's great vision for a mechanism that opens a door when it detects a secret knock. Here it is in action:
As you can see, he's programmed the microcontroller to listen for a specific knock sequence. When it hears it, it turns the deadbolt, meaning you can open the door. It's a simple but genius idea.
We're hoping something like this comes to market. Sure, it's not the most secure idea in the world, but it's fun enough that it'd be great for the inside of homes or backyard sheds or underground sex dungeons.
EA demos a 3D car-racing game on the BlackBerry Storm.
(Credit: Photo by Jessica Dolcourt/CNET)"OpenGL ES" and "Eclipse" may not mean much to you if you're not an application developer, but ordinary BlackBerry owners will soon be able to benefit from the string of announcements uncovered on Monday at RIM's second, annual BlackBerry Developer Conference.
BlackBerry-maker RIM announced on Monday enhancements to its BlackBerry application development platform--including four APIs for developers to more easily integrate ads, payment services, geolocation, and push notifications for third-party developers.
What does that mean for you? The new tools and features for developers should make it easier for them to create richer apps and do so faster. For instance, new support for OpenGL ES, a graphics API, makes it possible for developers to create 3D games for BlackBerry. Electronic Arts (EA) hopped on stage to demo the car-racing game Need for Speed-Shift on the Storm. The game includes new touch controls, like swiping to activate a speed boost or touching the screen to apply the brakes.
Very soon you'll start seeing visual themes and widgets available for purchase and download in BlackBerry's App World. RIM's new BlackBerry Theme Studio 5.0 will let developers include ringtones in themes. As a result, a theme you download through App World might replace your default ringtone with one that matches the visual theme, like the "Batman" theme song to mirror your "Batman" wallpaper. The ringtones sound very cool, but are limited to BlackBerry phones running the 5.0 operating system or higher.
As Apple has done, RIM will soon be adding the capability to make in-app purchases on a BlackBerry.

This is the 411, my Q&A column answering all your questions about cell phones and cell phone accessories. I receive plenty of questions about these subjects via e-mail, so I figured many of you might have the same questions, too. At times, I might solicit answers from readers if I'm stumped. Send your questions and comments to me at nicole.lee@cnet.com. If you prefer to remain anonymous, let me know in the e-mail.
First off, thanks for your recent piece comparing the smartphone voice and data plans. Very helpful! My question pertains to smartphone flash drives. Most of the current smartphones allow the user to add storage via a flash drive, usually a microSD or SD card. When I read the review about the smartphones, I often see some kind of statement regarding flash memory that seems to indicate that their is a maximum amount of storage that a device will accept.
For example, the review of the HTC Tilt 2 says, "The Tilt2 has up to 32GB of expandable memory while offering 512MB ROM/288MB RAM." So my question is: is the maximum amount of flash drive space that a device will accept limited by the device itself (e.g., hardware/software limitations) or is it limited by the amount of flash card storage that is currently available in the market (referring back to the Tilt2, the device will accept a 64GB card when it becomes available)? -- John, via e-mail
HTC TouchPro2
(Credit: Verizon Wireless)As far as I know, the expandable memory limit is indeed limited by the device itself. So even if a 64 or 128GB card becomes available, you will not be able to use those cards in the phone. Perhaps the firmware of the phone might be upgraded to handle the new cards, but I'm not sure if that is possible.
Nicole, I'm a 56-year-old with big hands and bad eyes, so a lot of this smartphone technology is wasted on me. My office wants me to get a HTC Touch Pro2 (bigger screen and keyboard), but I'd prefer to use my Verizon cell phone as a Wi-Fi device to access my company's Web site and my e-mail account through the Web through my laptop. What would you recommend for me? -- Paul, via e-mail
... Read moreYour friends call you a klutz, Mom calls you careless, and you beat yourself up every time you drop your phone in the toilet or step on your MP3 player. We can't help you with your overall clumsiness, but there may be a solution for your soaked devices.
The Bheestie Bag is a small, lightweight pouch that draws moisture out of personal electronics using small, liquid-absorbing beads. After the device has been soaked or spilled upon, take the battery out, dry the device, and place it in the bag for 24 to 72 hours. The beads absorb water in much the same way rice absorbs water, as they are made to physically bond with liquid and don't release the moisture back into the bag when they've reached their absorption capacity.
At first, I thought Bheestie Bag was just another mythical solution for rescuing drenched devices, but after putting it to the test using a soaked Insignia MP3 player, I'm far less skeptical.
Other well-known device-drying methods come to mind, of course, the most infamous bring the blow dryer. Unfortunately, it's more likely that you'll further damage your device under the dryer's heat, so it's not recommended.
There's also the "just let it sit" myth. Many, like CNET News reporter Ina Fried, have tried this and seen positive outcomes. But I have a feeling that the success of this method has a lot to do with the inner workings of the device and how crammed the parts are. If there's a sufficient amount of open space in the device for air drying, it's more likely that if you "just let it sit," the device will work again.
The last, less obvious tactic is the bag of rice. Here, you simply dry off your device, remove the battery, and place it in a bag of rice for a couple of days. Since rice is a natural soaking agent, it supposedly removes the moisture from the device. Like many others, I can say this method works.
Despite these available solutions, none have proven to be consistently successful. Luckily, after trying the $20 Bheestie Bag, I can say there's a more dependable solution for those of you who are accident-prone. See our photo gallery for more on our experience with the product.

Creative's ZiiLabs announced on Monday the ZMS-08 processor, its third-generation product that brings 1080p H.264 decoding to the table.
According to ZiiLabs' specifications page, the second-generation ZMS-05 is capable of H.264 720p video decoding at 8Mbps, while the new chip does H.264 1080p at 40Mbps and also boasts OpenGL ES 2.0 support, an integrated HDMI controller, and Flash acceleration.
This chip is powered by a 1GHz Arm Cortex A8 processor. It's targeted at media-rich applications, yet is supposed to have low power requirements. ZiiLabs does not make any consumer products itself but intends for the ZMS-08 to be used by manufacturers in devices such as Web tablets, Netbooks, connected TVs, video conferencing systems, and home media hubs.
While 1080p video playback would be pointless in some of these products because they usually come with small screens, it will allow the devices to output HD material to larger displays, effectively giving you a media hub in your pocket. The company says it's working with partners, but there hasn't yet been any product announcement from third-party manufacturers.
The Zii Egg portable media player is an example of what ZiiLabs' processors are meant for. The ZMS-05 is found in that device, which is a developer platform for the company's own Plaszma OS and Google's Android OS.

The hardware added to this cell phone costs around $10.
(Credit: Ozcan Research Group/UCLA)To picture the next-gen microscope, don't picture a microscope at all. Aydogan Ozcan, an assistant professor of electrical engineering and member of the California NanoSystems Institute at UCLA, is adapting cell phones to sample biological images.
This is no iPhone app. Ozcan, who formed the company Microskia (on the heels of the UC Berkeley team that developed CellScope), has built a prototype whose cell phone camera sensor can detect a slide's contents at a cellular level--reading, for example, an increase in white blood cell count that might indicate a new infection or injury. That information can then be forwarded wirelessly to a lab or hospital.
The brilliance of Ozcan's design is that magnification is done electronically, requiring no lens. (CellScope, on the other hand, takes a more conventional approach as a miniature microscope with expensive lenses.)

The Pyramids at Giza sound like the perfect place for an Apple Store.
(Credit: Crave UK)Apple has opened an Apple Store at the Carrousel du Louvre in Paris, an upscale shopping center beneath the famous Louvre art gallery. We reckon Apple products will look right at home in an art gallery, and we've come up with some suggestions for where Monsieur Jobs should open the next branch of Apple Store.
The new Magasin du Pomme, which opened this weekend, is located beneath the Louvre Museum. It features the usual white decor and split-level glass staircase.
The Paris shop is the first Apple Store in France. A branch in Montpellier was ready sooner, but the opening has been held back until Saturday to let the Paris branch grab the headlines. Microsoft, which is branching into its own dedicated stores, has a cafe on Rue Sebastopol where Parisians can try out, but not buy, Windows 7.
So where next for Apple? Here are our suggestions.

Initially inspired by the keyboards on the Treo smartphones, the OOMouse was designed by a game designer who was annoyed with the paltry number of buttons available on high-end gaming mice.
(Credit: WarMouse)First impression of the OOMouse? Wow! Never have we seen so many buttons on a pointing device (18 at last count). To top it off, it may even be the first mouse to sport an analog joystick on the side.
Private company WarMouse is primarily marketing the OOMousebeing as a peripheral for OpenOffice (a Microsoft Office alternative), but we feel it's targeted at the wrong audience. With the 18 programmable mouse buttons, clickable scroll wheel, three different button modes (key, keypress, and macro), and up to 16 macros on the joystick, the OOMouse can launch 52 different commands with the touch of a button. This makes it perfect for real-time strategy games like World of Warcraft and StarCraft 2. Thanks to the onboard memory, the mouse itself can store specific macros for up to 63 different games and applications. The resolution can also be adjusted from 400dpi to 1,600dpi.
Our only complaint? With so many buttons you'll probably need an exceptional memory, especially when switching between programs. The OOMouse supports Windows, Linux, and Macintosh operating systems and will retail for $74.99 when the online store opens.

The iPhone gets HD radio.
(Credit: RadioShack)Staying competitive in an iPod-ruled marketplace is a challenge, and not just because of the player's built-in virtues (or Apple's massive marketing budget). The reigning king of the MP3 players has an advantage simply because it resides at the top of the heap, and that advantage comes in the form of feature-adding third-party accessories. Case in point: the Gigaware In-Line Remote with HD Radio, an $80 add-on for the iPhone and iPod Touch.
That's right, kids...that would be the iPod addressing a major selling point and advantage of the Zune HD. Please don't act surprised. You knew this day was coming. And yes, the Gigaware remote does allow display of track information on the iPod screen as well as song tagging, which let's you find songs easily for later purchase.
So let's recap: 32GB Zune HD costs $289; 32GB iPod Touch with HD radio addition costs $379. Not exactly apples to apples, but which one do you find more attractive? Does HD radio even matter? Discuss.
Just before it got out of control
(Credit: Wilson Tang, Justin Yu/CNET)Now that we've had ample time to recover, Wilson and Justin take a few moments out of today's episode of The 404 Podcast to attempt to retrace the events of Wilson's Friday night birthday bash. The night started with a stomach full of Korean Fried Chicken, which you should definitely check out if you live in New York--it's addicting, for real. After that, Wilson surprised us all (not really) with a night of karaoke, which started off innocently enough with Aqua's Barbie Girl and Enrique Iglesias' "Escape," but quickly turned into a rockstar-wannabe free-for-all as Justin and Wilson laid waste to their dignity and belted out that awfully addicting Black Eyed Peas song "I Gotta Feeling." MAZEL TOV! Check out the show to hear all the details and follow the photo slideshow to witness our humiliation.

If you've ever wanted to show a Facebook friend how much you despise their mundane status updates and links, a "dislike" button might be your dream feature come true. French developer Thomas Moquet created a Firefox Extension that adds a dislike button to Facebook pages, but other Facebook users must have the extension installed as well to see the note. If you're not a fan of the open-source browser, there's also a Facebook Group that you can join to petition for the absent feature. The question is, should we really bring that element of negativity to our beloved social network? Listen the entire episode to hear our point of view.
In atypical Monday fashion, we actually dig deep into Internet censorship and the age that kids should be allowed to play games rated "Mature." The conversation is sparked by a very informed 13-year-old who left us a voicemail bringing up a great point about the different maturity levels that exist within a specific age bracket, and we're happy to discuss a topic that raises so many questions about maturity level, parental responsibilities, censoring Web content, etc...it all goes down in the second half of the show, so listen up and leave us a voicemail (1866-404-CNET) or e-mail the404[at]cnet[dot]com to voice your opinion!
