Do you have a bunch of people sneaking around that you want to not only catch, but expose to the world? If so, then this laser tripwire project is worth a try. You have to hook up a laser pointer, a photoresistor, and a webcam all together, and voila, you have a laser tripwire that will capture a photo of the intruder and upload a link to the photo on Twitter.

Think of it as a basic home security system. In fact it would be great if more security systems used this while the home-owner is away. The cops and Twitter would have a picture of any perks who break in.

If anything will get you to change your existing mouse, this will. Canon has just introduced the X Mark I Mouse, a wireless laser mouse that doubles as a fully functional calculator and a numeric keypad. Bluetooth 2.0 is responsible for the connections, and it has A 1,200dpi sensor.

It’s also compatible with both OS X and Windows platforms. Get ready to crunch some numbers while mousing in November when it launches. Just £39.99 / €48.99 .

At the Taiwan Broadband show Ericsson showed off it’s take on a portable computer of the future. It uses a pico-projected screen and laser-projected keyboard. At least you won’t make any noise while typing. Pictured above is just the prototype.

With these Lazer Trip Wires you can set up an invisible perimeter to alert your of any unwanted invasions of your “space”. The devices don’t actually use real laser beams (hence the spelling ‘lazer’), but use infrared beams to create an invisible trip wire that sets off an alarm when anyone crosses it.

The kit comes with three devices, one main and two secondary units that each send and detect a beam. You can set up two that point at each other or all three or more to create a perimeter. Each …
