Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the ...

Linear Technology's recently introduced LTC4300 chip buffers I 2 C clock and data lines to and from a hot-swappable card. This task is difficult because the IC must work bidirectionally, meaning that ...

This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...

Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ...
