This circuit was found in a 1975 documentation. The SCR can be of any type and in this case, we have the horn activation. The relay must be a 12 V type with high contact current.
Bipolar transistors are types of general use like BC548, while the power MOSFET can be of any type...
This circuit generates a signal rich in harmonics that extends up to close to 1 GHz, serving for...
This second-order low-pass Salen-Key filter was obtained from an American 1980s documentation. Formulas...
