This is version 1.0 of my circuit.
The LEDs at bottom center is on a wire to sunglasses you drill out as to position the LED over the center of the closed eye.
I’ll write a detailed explanation and how-to soon. But for those who understand this schematic, here it is.
Simple as it can be and fast to make.
Let me know your progress.
