if you want another, let me know. I do not know if they work, but
would be good for spare parts.

BUT, if someone figured out how to hack these for SLOW speed to use
as a PCB marker, or etcher they could be of good use.

right now, there is a guy on e-bay with thing boards, 20 thou. that
would probably about the thickness these could handle.

Ideally, someone could make an interface that ran them from a CNC
package. drilling would be the problem as I see it.
