I recently wrote a guide to making a "poor man's" night vision setup for FPV. Still testing it at the moment but its coming along quite nicely. Rather than write the whole article out again I have link the pictures with the article in.... YouTube comparison video:-
We added an IR illuminator to a modified board camera to make night vision. Still needs some work, I think I need to add another IR illuminator at a different angle to get better coverage from the IR beam.
This is absolutely amazing! Brilliant work and thank you for sharing, will certainly try this myself at some point! ;D Although I have to ask, how many cameras did you go through trying to perfect this?
