How To Tether Your iPhone With NetShare
Posted by Matt Hickey at 8:00 PM on August 4, 2008
We've been covering NetShare a lot the last couple of days, and with good reason: Apple consciously left the ability to tether out of the iPhone, yet for some reason has no problem letting someone else sell an app that does just that. Some users, though, might find the concept of tethering confusing, or at least intimidating. It's actually quite straightforward, and the staff at Apple Insider has put together a really handy and detailed step-by-step guide that shows how in just a few minutes you can configure your MacBook (or other Wi-Fi device) to share your iPhone's internet connection so you can have truly mobile access anywhere you get coverage.

Maclife suggests ferrite beads as a fix for the GSM buzz emanating from speakers when placed near a busy mobile phone. I found some of the snap variety you can order

Don't you hate it when your perfect heist is foiled by some hidden camera that serves your head to the police on a platter? Well some deviant genius posted a video on Metacafe showing you how to create a pair of LED shades that hides your face on CCTV. All you need are a couple of LEDs, some wire, tiny batteries and a bit of skill. But if committing felonies aren't quite your thing, maybe you'll appreciate the fact these also make you look like some possessed spawn of Satan on camera. [
There's a Lucid Dream Machine sleeping mask on Instructables that pulses LEDs in your eyelids four hours after you fall asleep, waking you up just enough to notice your dreams and control their outcomes. The mask requires a fair bit of soldering and programming experience, so it isn't for DIY luddites like me. Which is good, because my sleep is too precious and my dreams are too weird to want one of these anyway. [
With the possible announcement of the 3G iPhone only a week away, many current iPhone owners are itching to upgrade, which takes money. Other people, finally bitten by the iPhone bug, are eager to buy one, only they are harder to find in stores. This creates a nice, natural supply-and-demand formula that we managed to exploit not once but twice on eBay. Not only did I sell my iPhone in 24 hours, but I sold it for more than I paid.
No wonder Tony Stark managed to do an arc reactor in a desert cave. According to this tutorial, you really only need some LEDs, a 9-volt battery, plywood, 22 AWG gauge copper wire, assorted resistors, and a substance called polymorph—which can be made into any shape—to create your very own virtually-unlimited power source. Or look like the geekiest homeless person at any costume party. The mask is even better.
Like with any major purchase, you simply can't walk in to the nearest electronics store, point at a HDTV saying "gimmie" and expect to get a great price. If you want that great deal, you will have to do a little research on the subject. Fortunately, the guys at HD Guru have provided some CliffsNotes to help out the novice consumer on a budget.
Giz reader and Batman-wannabe Suneth Attygalle has built these cool, albeit a bit goofy looking, ultrasonic batgoggles. As you can see in the video, they allow the wearer to detect the proximity of objects using just US$60 in components, including welding goggles, a microcontroller, and ultrasonic sensors.
