My laser arrived few days ago. Here is a demonstration I made, from some plastic (half-transparent plastic lid), and a HDD (works good as a mirror).
It’s very powerful, it reaches as far as 1km (couldn’t test further, I got no buildings that far from me). Here is the photo with low exposure time, you can see the beam clearly in the night.
You should’ve picked a green one instead. I’ve got a 100mW green laser pointer which emits a beam that just doesnt want to end at night :P
Green lasers are more expensive and less cool (classic red ftw)
:V
Omg. Can you burn people with it? :P
Human skin is too reflective to give someone burns, but you can burn through dark clothes
