This circuit implements a 3-way control, with outputs in A, B and C, using CMOS integrated circuits. I found this circuit in an old publication from 1978.
We found this circuit in a Popular Electronics from the 80s. This circuit eventually doesn't work with...
This traditional high sensitivity voltmeter circuit using a FET can employ the MPF102 or BF245 in its...
This circuit operates at a voltage of 1.3 V from a single mercury cell. We found in an old...
