We find this oscillator in a 1980s documentation. The frequency depends on the crystal and the transistor used must be able to oscillate at the desired frequency.
This 1987 circuit has a very interesting concept. It powers a second set of rhythmic lights from...
This circuit was found in a 1970s documentation. The integrated circuit used is uncommon today....
This circuit was found in a 1964 Electronic Design. The circuit makes use of transistors of the...
