Hello!

New to the community but I've been studying whiteboards for a while now.



I've already made myself 5 IR pens (4 shown in the picture, another one is now disassembled).

I would like to take some further steps in long distance recognition of the IR light beams (even if laser is not an option).

Thanks!

Giuseppe :-)
