What do you need to build a DIY laser based 3D scanner? A camera (e.g. web cam), a line laser, plain boards, PC and laser scanner software.

"Do it yourself Gadgets" didn't want to buy the line laser so he just made his own from supplies he can find in his home.

He tried two different methods of building line lasers. For the first build he used a small DC electric motor, a cheap laser pointer and small mirrors. He glued one little mirror to a squared board and mounted on the DC motor, then he added holders for the laser.

When the motor spins the mirror that reflects laser will draw a perfect line across the object he is scanning.

The second line laser he built was from the parts he disassembled from an old hard drive. He removed the actuator mechanism and mounted a small mirror on the actuator arm. Then he attached the actuator's coil to an AC current so when the AC current caused a vibrating actuator arm the laser could draw a line.
