Hello Psn,

I have this laser pointer and was just wondering how
it might be used with mirrors to detect ground motions ?

How about two silvered surfaced mirrors that bounce the light
between them at a slight angle sort of like you see yourself
a zillion times in a mirror at the barber shop ??

a teeter totter mirror bouncing off a light beam ?

What kind of sensor for a red LED laser pointer ??

Any ideas ?

Regards,
geoff
