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.
The critical point in this 2005 project is the adjustment of the optical system, mainly to avoid...
This simple SCR trigger was found in a 1965 General Electric SCR manual. The circuit makes use of a...
We found this circuit in a 1976 technical documentation, but it can be assembled with modern...
