This circuit was obtained from Popular Electronics from June 1978. It doubles the input DC voltage. Obtained current is very low, serving only for polarization circuits.
With the presented circuit, random patterns are generated for the flashing of 8 LEDs, leading to a...
The author of this project found in a 1983 publication says that he uses this mini amplifier as a...
Found in English documentation from 1989, this circuit appears elsewhere on this site, taken from...
