Laser cutter, start slicing stuff for under 50 dollars

Featured

Step 1: Get your supplies

I say that this costs < 50 dollars. And it does, you can even get it cheaper if you have a broken scanner.

Here's the list:
1x Laser diodes Ebay Store $36 dollars for 2
2x Old Scanners Salvation Army $10 Dollars each
2x ULN2003 Electronic Connection $5
1x Prototyping board RadioSchack $2
2x 3/8" Aluminum Rod Home Depot $3 each
1x 3/8" Aluminum Tube Home Depot $3
10x Brass Brackets Home Depot $1
1x 2" cube of wood Home Depot $1
A bushel of Patience

Here is a video showing all the supplies you'll need including the tools:

 excuse me, but the link to the laser diodes ends up in a store which no longer has diodes in it. what power was the diode that you used? and what all materials/thicknesses have you cut with it? also, have you had any issues with fire? sorry for all the questions but i've never build a CNC before XD

Could you use the Diode/laser thingys from a dvd player/recorder or Blueray thing insted, of buying them off ebay?
yes you can dvd burners and blue ray players have incredebly strong diodes that can cut paper, pop balloons, and light matches. those would be perfect for this.
