Yet another computer mouse combo thing (we had the Ezkey Keypad Mouse yeterday). At first look the USB Mouse Calculator ($30) doesn’t feel as useful as the Ezkey can be, considering all computers already have a calculator. The good thing is that it actually doubles as a keypad. The question is how comfortable this mouse really is?

The Shake-u-lator Calculator ($20) doesn’t require any batteries to operate. Simply give it a quick shake and you’re set to do your algebra.
This 8 digit display calculator uses Faraday’s Principle of Electromagnetic Energy to operate. You will no longer have to buy replacement batteries for your calculator. This battery-free calculator is powered by shaking the calculator side to side. Shake the calculator so that the magnet slides through the copper coil in the visible chamber around 20-25 times, and enough electricity is generated to operate for 10 minutes. If the digits on the LCD screen dim, just shake it a few more times to recharge – their calculations won’t be lost during recharging…
