T-Mobile Probably Did Not Sell 1.5 Million G1 Pre-Orders
4:45PM Gizmodo US Edition | Did the announcement that T-Mobile sold 1.5 million G1 pre-orders sound a little too fantastic to be true? Information Week thought so and talked to the guy behind the astronomical number–a mathematician at The Motley Fool. Turns out that some iffy multiplication may have been involved and the number of pre-orders sold is probably closer to 200,000 to 300,000. Big, but not crazy big. More »

1:46PM Nick Broughall | Turn A Calculator Into A Metal Detector – video powered by Metacafe
Our good friends over at Lifehacker found this video tutorial gem on how to create your own metal detector on the cheap.
Essentially, by just sticking a calculator on the back of an AM radio you can create an annoying tone sound when you put the two near a metal object. There’s something about radio frequencies and digital signals or something, but who cares how it works when you know that it does work.
As far as hacks go, you won’t get much easier than this. Plus, you’ve probably got the necessary components somewhere in your garage. What better way to spend your evenings?

Piano Calculator Makes for Musical Math
12:40PM Sean Fallon | If math wasn’t already annoying enough, this unique piano shaped calculator plays a tune with each key pressed. In the right hands, crunching numbers could become a tiny concerto. But in your hands, it will undoubtedly result in a swift and brutal retaliation by your fellow co-workers. Let’s just hope Phillip Glass doesn’t get wind of this. Available for 1000 Yen or around $10. [Product Page via TFTS] More »

Make a Metal Detector For Like 5 Bucks and 2 Minutes
8:10AM Mark Wilson | We’ll admit it: we’ll lack the ambition to perform most of the hacks you read about on Giz. But taping a calculator to an AM radio to make a metal detector? That’s right up our alley. And by “right up our alley” we mean probably still too much effort…but not by much. More »
Digital Card Calculator Spycam Is Sneaky Circa 1985
12:45AM Wilson Rothman | You’re in a hotel lobby when your mark walks in. You pull out the Digital Card Calculator Camera and pretend to casually crunch sums, while in reality you are snapping Top Secret Digital Photographs. Your target would only know you’re a spy if he/she spots the enormous VGA lens and bezel right next to the keypad. It’s a good thing, then, that you’re reasonably inconspicuous in trenchcoat and matching fedora. A technical question, though: if it’s got a lithium-ion battery for the camera and a 1.5V button battery for the calculator, how’s come the solar panels? More cloak n’ dagger deception, I imagine.

ThinkGeek’s Calculator Bot May Love You
5:55AM Haroon Malik | When you are having difficulty with your arithmetic, would it not be great to have a small, robotic calculator at your beck and call? Thanks to ThinkGeek, now you can! The Robot Calculator will not only confirm parts of multiplication tables you are unsure of, it will also hold down your spare paper clips on its magnetic back, illuminate your face with an LED light it comes randomly supplied with and store your rather short memos on the back of its small, calculating head. If that was not enough for $14.99, it may also cuddle up to you in bed…if you forced it to. [Retro to Go] More »
Chocolate Calculator Counts Calories
5:20AM Jason Chen | We’re not really sure what’s going on with this chocolate calculator, or Chocolator, but we’re pretty sure it’s not edible. Well, probably more edible than the LG Chocolate, but less edible than say, an actual chocolate bar without electronics inside. Now I can do my taxes and make a big mess all at the same time.
