This inverter with the 555 IC provides a high voltage output, but very low current. We found it in an 80's documentation. The transformer is according to the desired voltage.
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...
