Laser DIY – How to Make a Laser Pointer Controller!

Here’s a rather interesting laser pointer project that can detect where laser is pointed on a surface and will execute a desired command that you can set.  I think this type of project can be very useful for certain applications, enjoy~~

Laserspotcam is a software I wrote to control xmms using a laser pointer by pointing defined areas on a wall.

The software monitors the wall for the presence of a small spot using a webcam. When the spot appears somewhere, if it is inside a defined hotspot, the appropriate command is executed.
