Using a 106 series SCR, this circuit was found in the May 1971 Radio Electronics magazine. The quiescent current is very low and is given by the value of R1.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
