The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...
