Kids can be pretty resourceful creatures and there are not many ways of stopping them from doing who knows what on the PC. That is until KidSafe came along, a USB key that is exactly that a key for your PC.

Computer geeks and white-hat hackers in the UK developed the KidSafe Parental Control Key to help lock down computer access in the easiest and most secure way possible. Each key is unique and cannot be duplicated. When inserted, the key allows your computer to boot and access the internet. When removed, the computer is locked tight, and unusable.

Kids today are smart, and can get around Windows passwords, and Internet filtering programs pretty easily. Proxies and workarounds exist for even the most draconian firewalls, but the KidSafe key protects your computer and your kids with a physical key. It’s stronger, more reliable, and more convenient than passwords. It can’t be uninstalled or worked around – even by booting to safe-mode. They’ve even got processes to keep your computer from booting to a live CD or other boot device.

You can buy the KidSafe security key from Think Geek for $59.99.

I always wanted to go to the Arctic Circle so I can see one thing, the Aurora Borealis. But, thanks to GensoOurora I don’t have to brave the bitter cold and ice. This neat device mimics the Northern Lights in the comfort of your home. At $60, there is no word yet on how realistic though, but it better be good.

Vent your frustrations with this remote controlled VS Tanks kit. It comes with two infrared-enabled machines, two controllers, and a battlefield.

The tanks have a rotating turret, a machine gun, can do "super spin" moves, and sports flashing LEDs to show when you’ve been hit. Each unit fires out AirSoft pellets and can be equipped with an "action cam" to record your moves for posterity. Coolest Gadgets
