Circuit Pattern Cards Provide a Resource for Tinkerers

Nick Johnson’s circuit pattern cards each feature an important circuit that you’re likely to need if you’re an electronics tinkerer. For example, the voltage doubler circuit on the card above shows you how to use capacitors and an inverter to double the voltage output by the circuit.

Nick’s company, Arachnic Labs, offers a deck of 32 different pattern cards that detail commonplace circuits. You can buy the decks at Nick’s Tindie store or you can also find them on Adafruit.
