Damn, those 0402 Leds are tiny

A project log for LIGHT LOGIC - HIC SVNT DRACONES

Using a LED/LDR pair to form inverting Photonic logic gates. The entire Boolean logic set handled by resistors and diodes! Who'd'a thunk

Now that is a little bit more secure.

With bare hands and my glasses off, I managed to attach a 0402 led onto a CdS LDR and solder tiny wires to the led.


First I found out how much of a size difference there was between the two parts.

Yes, the led is on top of the LDR
