The Arduino powered Laser trip wire system project is currently over on the Kickstarter crowd funding website looking to raise $3,000 pledges to make the jump from concept to production.

In the video above, MAKE Magazine shows how to create your own laser tripwire for just a few dollars worth of electronics equipment. If you want to get into the nitty-gritty, you may need some ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

It works in a home aquarium with toys, but could this laser tripwire alert people to hungry sharks approaching swimmers?

You’ll learn how to build and program a motion detector with a laser tripwire, a long-distance Bluetooth listening device, a voice modulator, and even connect anonymously to the internet.
