Scanners are not cheap, even my home built one has cost me around £250. You cant make a scanner using normal DC motors, but you can make a spyrograph. Simply stick some mirrors at a very slight angle onto the motors so that they rotate at a angle. Then set them up in a way so you can point the laser at the first rotating mirror, it bounces off that one and hits the other.

Vary the speed of them and you can create a spyrograph type effect.

i just bought a RGY scanner from chinese Dept STORE for 150 with shipping
