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.
We found this circuit in an old documentation from the 70s. The sensor is an LDR that must be...
This low noise audio amplifier stage uses only one transistor and has a high enough gain to...
In fact, the 556 consists of a double 555, which can be replaced by these integrated ones. The...
