The points A and B on the circuits with LM386 can be used to stop the oscillators with elements having open collectors or open drains; for the NE555, the reset input serves the same function.

I wondered what was going on, but at that point I was in the midst of some other circuit work, so I put the parts aside. Recently, I got a new power supply, a Siglent SPD3303X. It was about time! I ...

the NE555. (Video, embedded below.) The circuit is simplicity itself, just an astable of the type that has made a billion beepers and flashing LEDs. It drives two ultrasonic transducers in ...

Many integrated circuits have undocumented features or abilities ... While it can be seen that the NE555 has the higher current rating, its saturation voltage is grossly inferior and this is a ...

One of [NE555]’s boards from the 90s. Over on twitter [NE555] has been posting beautiful SMD prototypes. Back in the 90s when surface mount components gained widespread adoption, the quick and ...
