We found this circuit in a 2002 documentation. This die shows numbers 1 to 6 on a common anode display when the switches S1 and S2 are pressed. The circuit can be powered by voltages from 5 to 12 V.
Here we show a configuration in which we have a control voltage applied from a voltage divider, which...
This different power control circuit with SCR was obtained from a 1967 magazine. The SCR can be...
The circuit that gave rise to this configuration was found in a magazine of the 1980s with the...
