Hi Win,
In AoE (2nd ed) page 1034 you describe a demo for your students whereby
you detect a dim LED.
Did this demo use a commercial lock-in amplifier or did you roll your
own?
Is it practical to build a simple demo circuit using a smallish number
of parts?
I'm thinking along the lines of a "Saturday arvo project".
BTW, what's the latest on the 3rd revision?
Cheers,
Ian Du Rieu
