This very detailed Dimmer was found in an English documentation from the 90's. The SCR could be a modern equivalent like the TIC106. The circuit is only suitable for incandescent lamps.
We found this circuit in an old American publication. The transistors can be BC558 and diode 1N34....
This simple circuit operates with only 1.5 volts of a battery and detects low resistance making a...
The cascade connection of two flip-flops allows division by 4, as shown in the figure. Note that...
