I can think of a few uses for a radar gun around the house. For instance, I would like to see exactly how fast that teen girl flies up my street as she sends a text message. It would also be cool to see how fast the kids can ride their bikes down the hill out front. A new gadget called the Pocket Radar has been announced that will let you do these things and a lot more.

Pocket Radar can be used to get the speed of any object with accuracy to one mile per hour. The working range of the device is a full mile. The manufacturer says that NASCAR fans can even use the radar from the stands to see how fast their favorite driver is going.

This cool new ultra wide band radar system was developed by UK based company Cambridge Consultants. Working like a pair of X-ray specs, it will let you see through walls. Sadly, only moving objects can be seen, but it can detect breathing movement and even a beating heart.

Happily, that should include bouncing breasts, you know, should someone be working out on the other side of the wall. I’d hate to miss them just because this system only sees moving objects. The software in Prism 200 allows the user to remotely observe the scene in a 3D view and you can do the usual rotate the room/building to whatever angle you like.
