His requirements were to create a minimalist, credit card sized design, with his contact details printed on the silk ... [Dennis] has shared KiCad schematic and PCB layout files for anyone looking ...

Earlier this year [Skyhawkson] got ahold of an Apollo-era printed circuit ... point and create KiCad schematics. Hopefully we can figure out what this circuit board does along the way.

Printed-circuit-board ... Finally, the circuit extraction includes de-layering the PCB to generate schematics and netlists. As reverse engineering is usually applied to old PCB designs, ...

The two diagrams above are of the same circuit for a simple night light. How it works: when darkness falls on the light dependant resistor (LDR), its resistance increases causing a higher voltage ...
