Subject: laser on presensitized

Cheap UV 100mW cw lasers (BluRay) on eBay.
It emits on 405nm, but some presensitized pcb (like
Bungard's/Germany) responds to that light.
Good to replace the CNC PCB Machine's tool (to get the traces
registered with the holes) , or the plotter's pen.
See my idea/calculations in the group's archive # 7191- #7213.
