I guess small mak would have much better performance than these Chinese magnifying glasses :D. Still interesting project for anyone interested.

 

 

Reminded me of a project "Light Beam Communicator" in "Electronic Novelties for the Constructor" by EM Bradley (which predates the invention of the laser), one of the first books on electronics I had as a lad in the early 1960's

Boys, huh? Because girls really would not have been interested in talking to each other back then and, of course, electronics would not have been a suitable interest either! Thankfully things have changed. V1 and V2 are some strange looking transistors! ;)

Amen to that, though there is still some way to go in Physics. When I started my degree in 1969 there were just three women in my year (~5%). That has improved to ~25% now I understand

Cheers
