Shows drawing on wood with a 1W laser at a reasonable speed

I notice 500mW (250mA @ 2V) green pointers are for sale in
NZ for $75, possibly that might be enough

Exactly what more use 500mW is over a cheap 5mW pointer, I'm
not sure. 500mW is extremely dangerous to be waving around

>From what I can gather, lasers in domestic appliances (drives
and printers) aren't powerful enough
