This traditional dimmer configuration for incandescent lamps and heating elements was found in an RCA transistor manual. SCR can be a more modern equivalent like TIC106, depending on the power grid.
This circuit has been found in an old documentation and therefore uses a lamp as an indicator. In a...
This monostable circuit uses one of the two flip-flops available on the CMOS 4098 integrated...
This project came out in an article of mine (Newton C. Braga) in the Popular Electronics magazine of...
