Reading about all those lucky people that have access to a laser cutter, i was wondering: can we make one? I mean, build a custom (cheap) laser cutter?
I think it should be something like a plotter, so with a couple of fine-grained steppers and a frame structure (maybe some old scanner) that should be ok.
The problem is the cutting :P where can one find a good laser? i thought about CD-Writer but they have about 100 mW.. I don't know, maybe it's enought for a small dark acrylic sheet.. But i think the optical stuff won't fit :)
