I happened to catch this interesting hack on core77 and tried it for myself. You take four business cards, cut them up to interlock, leaving enough space for your earbuds to nestle inside, pop it open a bit and voila -- instant speaker cones for the tiny music makers. My MacBook Pro's headphone port recently became stuck in the line-out mode (the Cylon light is glowing and yes, I've tried to slide the little switch), and until I can get it to a shop I'm using these as my "speakers." Obviously the primary use would be for iPods, or anything without a built-in speaker.

Does it work? Hey, it's better than nothing. But don't expect to hear much if the noise in your area is anything north of murmur. The decibel boost is negligible, and the amplification is somewhat directional. It works well if you have an ample belly to rest the speakers upon when lying on the couch, as I do. A neat exercise in creative thought, all the same. If anyone can figure out the exact pattern the designer used, post a link in the comments.

I snapped some pics of me trying to replicate the design. I wound up altering it a bit, although my final speaker cone locks the headphones in quite firmly and can stand up in a variety of ways. It is narrower than the original, which doesn't help amplification. Check the gallery for details. Oh, and be sure to check out the neat iPhone earbud winder made from paper.

Check this out, folks. Some enterprising young hackers have got an IR keyboard working with a non-jailbroken iPhone. With nothing more than $20US worth of parts and the iPhone 2.0 SDK, they built an adapter for the headphone port that talks with a modified version of the audio port modem microcontroller firmware.

Of course, this isn't a rig that my Aunt Ethel is going to run out and buy for her own iPhone, but it's the first time we've seen an external keyboard working with an intact iPhone. Back in the day, my Stowaway keyboard brought my Palm ///e to unknown heights of usefulness. I'd like to experience the same glee with my iPhone.

Update: We've heard from two separate developers (Ari Weinstein and Jake Marsh) that they've put together quick and easy methods for enabling tethering on 3.0 iPhones (an all-in-one tool and a full user guide, respectively). Check out the links for details.

When something so appealing as the possibility of wireless Internet access anywhere you go is dangled in front of you, is it any surprise when you reflexively reach for it? After developer Steven Troughton-Smith inadvertently turned on the tethering controls on his upgraded-to-3.0 iPhone, several people made a deliberate effort to enable the feature. Posts on personal blogs and at the MacRumors forums testify to the successful quest, and there's a specific walkthrough posted and a UK-specific IPCC file kicking around.

Of course, it goes without saying that tethering your phone, in the absence of a carrier contract that permits such connectivity, is the sort of thing that may get you in a spot of trouble. Examples of such potential hazards include extremely large data bills, summary termination of your account, or hair on your palms. While jailbroken phones have been tethering for some time with few issues, past performance is no guarantee of future outcomes.

There's a very cool video at Ralf Ackermann's blog showing an iPhone receiving input from an Apple Bluetooth keyboard. Of course, it requires a jailbroken phone, but Ralf claims that it works in all iPhone apps that make use of the keyboard.

This reminds me of the Stowaway Keyboard I used with my old Palm IIIe. I didn't mind Graffiti as much as some others did, but attaching that keyboard to my Palm increased its usefulness many times over.

Of course, I'd love to use a wireless keyboard with my iPhone. Since I won't be jailbreaking, here's hoping Apple (or someone else) will make this available to scaredy cats like me.

Around here, we used to call her "the unstoppable Erica Sadun" -- well, not to her face, but sometimes when she wasn't paying attention. The Queen of the iPhone Hackers has leveraged the undocumented video-out features in the iPhone 2.2 SDK, in cooperation with the clever folk at Freeverse Software, to produce the first playable demonstration of an iPhone game that displays on an external monitor. The one-off build of Moto Chaser plays best on a 2nd gen iPod touch (since it's got the fastest base hardware) and uses the device accelerometer for steering. On an HDTV, it outputs a respectable 20fps at 640x480.

Erica's post at Ars goes into the details of the work that Bruce Morrison and his team at Freeverse did to bring this custom build to rapid fruition, and it notes that this is in no way a product at this point; it's just a tech demo, although an impressive one. I had the opportunity to see this build in person earlier today at Freeverse's offices, and the surprising thing is how natural it seems to use the iPod touch as a game controller for big-screen play. With a less-intensive offering (a quiz or music guessing game would be ideal) and a design that takes advantage of the iPod's screen for simultaneous content display... well, I'd be game for that.

Video embedded in the 2nd half of the post. Check it out, and let us know what your dream game would be for a video-out setup from your iPhone or iPod touch.

While you're geeking out with your techie friends building battle bots or pumpkin cannons, why not give your dog a little love at the same time?

TUAW reader Stephen Myers sent us a link about a fun little project he worked on. He wants to be able to check on his dog's well-being and reward the dog with treats from anywhere he can use his iPhone. Stephen found out about ioBridge, a company that develops electronic monitoring and control modules that connect to any Ethernet network and can be controlled via an encrypted web front end.

Myers used an I/O module and servo smart board from ioBridge, a servo, an old CD spindle case, some cardboard and wood scraps, a large syringe plunger, and a webcam to build his device, and then used the ioBridge web interface to create a widget that controlled the device. No programming was required. The system generated javascript that was then embedded into a web page optimized for the iPhone screen, and now Myers can check up on Cooper, his dog, and give Cooper some treats.

Myers has many more details about the system in his blog entry, and he will be writing future posts about how he's using ioBridge and X10 controllers to turn lights on and off in his home -- from his iPhone.

Be sure to check out the YouTube video below!

Perhaps you've seen a Volkswagen Beetle driving around with a flower in its dashboard bud vase. People put all sorts of things in there, but we say ditch the gerbera daisies and go for something more useful.

Bug owner Nathan Barry has hacked his bud vase to accommodate his iPhone. By sawing away one slot for his USB car charger's cable and another to steady the iPhone, he made a clever stand that's easy to see from the driver's seat.

Good job, Nathan! My iPhone can be found bouncing around the passenger seat when I'm in my wife's car. The audio jack in my car is hidden inside the arm rest, which is even less convenient. Yes, I've tried FM transmitters but decided that they're manufactured by Satan himself.

So, how do you listen to your iPhone (or iPod) in your car?

Since the iPhone's introduction at Macworld in 2007, a large number of people have wanted a tactile keyboard. So far, Apple has not obliged. So, one iPhone owner took the initiate to make his own iPhone keyboard. Using a bit of Ruby code on a jailbroken iPhone, this user is able to connect a Palm keyboard via a 30-pin Dock Connector. The end result is an iPhone with a tactile keyboard. While we can't vouch for the validity of this video, it does look like a cool hack.

Here's a video and setup instructions for getting Mac OS X to run on a HP TouchSmart. The machine's main feature, of course, is the touch screen. It kind of works with OS X in that elements respond to touch, but the calibration is way off and, as the guy in the video says, there's no way to adjust it. He does offer to test out any other aspect of OS X on the Touchsmart, so speak up.

The setup instructions were written for a HP TouchSmart IQ507 and do require you do "grab a torrent" as the kids say. It doesn't look too tricky, though. The author notes that audio, the wireless card, Bluetooth and the TV Tuner won't work under OS X.

Still, it could be a fun project for anyone who's got a spare Touchsmart lying around. Don't we all?

I can always tell when I'm bored, because that's when I think up some challenge for myself. The initial spark for this challenge came when I wrote a post a few months ago about how Paul O'Brien at Modaco had successfully installed Leopard on a Windows-based "netbook". TUAW's Mike Schramm further fueled the fire with this post about an Eee PC running OS X.

Netbooks are tiny laptops with a mini price tag to match. Many netbooks sell for less than $500, with 1 GB of RAM, either a 16 - 20 GB solid state disk drive or 160 GB hard disk drive, Wi-Fi, and a built-in webcam. When you consider that these little machines also weigh about the same or less than a MacBook Air, they're a bargain. However, they usually run Windows XP or Ubuntu Netbook Remix, and frankly I'd rather have good old Leopard.

Asus has been making netbooks for a while under the Eee PC moniker, while MSI (Wind), Acer (Aspire One), and even HP have jumped into this growing market recently. It wasn't until I received a direct mail catalog from Dell featuring the new Inspiron Mini 9 that I started thinking seriously about trying to load Leopard on it.

Despite the fact that I'm sure that Apple will announce a low-cost netbook soon, I ended up buying a Dell Inspiron Mini 9 netbook to install Leopard onto. The rest of this post describes how I did it using instructions and files found at various Web sites.

If you use Stacks like we do, then you probably love any additional hacks you can do to them. While this Terminal Tip provides no really useful features, it does provide you with some awesome eye candy for your Stacks. This hack gives you a mouse-over gradient (seen above on Terminal) in your Stacks; just open Terminal (/Applications/Utilities) and type in the following command:

defaults write com.apple.dock mouse-over-hilte-stack -boolean YES

After you type in the command, type "killall Dock" to restart the Dock. You will then see the gradient in your Stacks. To get rid of the gradient, just replace "YES" with "NO" in the command above.

Have you been paging through a document and wished that the scroll arrows were at both ends of the scroll bar? With a simple Terminal hack, you can have it your way. Just open Terminal.app (Applications > Utilities) and type in the following command:

defaults write "Apple Global Domain" AppleScrollBarVariant DoubleBoth

You will need to restart your Mac to see the changes. If you want to change the scroll bars back to the normal way, just open the Appearance System Preference pane and select "Together" from the "Place scroll arrows section."

Mac owners often look on with envy at the Ultra-Mobile PCs (UMPCs) in the Windows world. These are truly tiny laptops, often with 10" or smaller displays and weights that make a MacBook Air seem downright obese by comparison.

MoDaCo network founder and Microsoft MVP Paul O'Brien decided to get his OS of choice, Mac OS X 10.5.4, up and running on one of these little wonders. The machine is a variant of a recently released UMPC called the MSI Wind, which weighs in at 2.3 lbs and sports the new Intel Atom N270 CPU running at 1.6 GHz.

While Paul admits to a few small issues, he was not only able to load and run Leopard on the Wind, but he also documented the entire procedure in text and video (see above) if you want to make your own Ultra-Mobile Mac. After watching how easy the process is and finding out how inexpensive the Wind is, I'm tempted to try this myself! Be sure to let us know if you're successful at following Paul's footsteps.

If admiration of an iPod-powered Lego vehicle indicates that one is a nerd, then buy me a pocket protector and hike my pants up to my ribcage.The folks at BattleBricks have constructed just such a creature. Here's (briefly) how it works. There are two iPhones involved. The one on the vehicle displays certain colors based on commands issued from the 2nd controller iPhone via a Safari app written with Google's Web Toolkit. The vehicle executes a command based on the color it "sees."

You can download the source code for yourself from Battle Bricks. Think of the applications! Frighten children and small animals, attach a small brush and clear away dust bunnies or deliver very small parcels.

Good work, guys. We love it.

An enterprising OQO user has gotten Leopard running on his tiny PC. If you aren't familiar with the OQO, it is billed as 'a full PC that fits in your pocket.' It has a slide out keyboard and runs a full version of Windows, and not Windows Mobile.

According to trf's forum posting Leopard is running pretty well except that video resolution is stuck at 800x480 and the WWAN card isn't working yet. Check out this YouTube video to watch the OQO boot up (it takes about 2 minutes to fully boot). Leopard seems to be running fairly well on the OQO, but don't whip out your wallet just yet. As with all non-Apple hardware that is running OS X, this isn't supported by Apple.
