This circuit, very critical due to the frequency at which it operates, was found in an American documentation that uses a resonant cavity in a beer can. The transistor can be of any type for RF.
The circuit shown has the component values calculated for a frequency of 1 kHz. TL064 can also be...
Voltage regulators from 5 to 15 V for currents of 1 A, can be easily obtained in the form of...
The frequency of this astable multivibrator depends not only on the capacitors, but also on the...
