We found this circuit in the July 1994 Radio Electronics magazine. The circuit uses a general-purpose transistor, and the power supply can be up to 12 V depending on the relay.
We found this sine wave oscillator in the December 1995 issue of Electronics Now. The circuit uses...
With this voltage regulator we can build a source of 1.7 to 17 volts and a maximum current of 1.5 A. The...
This circuit was found in a 1986 documentation. The circuit has a common configuration with the...
