This 1 MHz oscillator was found in an Electronics World of 1969. The circuit uses a general-purpose FET and the output circuit must be resonant at the generated frequency.
This 40-second timer uses common components. The output can be used to excite a power stage. With...
This circuit is from 1997 documentation, a time when the parallel port was the most common means of...
We found this circuit in a 1987 magazine, but the use of still common components allows its...
