A simple low-frequency generator on two transistors - a pumpkin turns into a carriage.
A low-frequency generator from B.S. Ivanov's book "Oscilloscope - Your Assistant."
A homemade audio generator (also known as a signal generator), or more precisely, a prototype for testing and refining the original audio frequency generator circuit. The video demonstrates the circuit's improvement by adding an amplitude stabilization circuit. The result is a single-range low-frequency sine wave generator with a frequency range from 150 Hz to 3120 Hz. Future plans include adding additional ranges to the low-frequency generator and boosting the power supply.
This video may be useful for beginning radio enthusiasts interested in the circuit design of simple devices using discrete components, making simple analog devices.
