This simple circuit consists of a blinker for a very low consumption neon lamp, found in a 1982 documentation. The circuit can be powered by 110 V for 1N4004 diodes or 220 V for 1N4007 diodes.
The circuit shown in the figure triggers a relay when S1 is pressed, but this only in the absence of...
This circuit uses operational amplifiers that must be powered by a symmetrical source to implement a...
This regulator can use BD'136 as the main transistor and as a reference next to a BC548 zener. The...
