Electronics Club. Multilayer High Frequency / High Isolation Printed Circuit Card. Electronics Project Design Schematics and circuit diagrams. Bitsbox. FC's Electronic Circuits. FC's Circuit Archive contains many electronic circuits that I have designed and documented.
I have attempted to include a number of unusual circuits, with an emphasis on useful applications over simple toy circuits. The majority of these projects can be built with readily available discrete components. Only a few of the circuits here rely on microprocessors.
