We change a few blocks and by setting the potentiometer we can adjust the charging and discharging of the capacitor.
Did you also notice that we use a 120 Ω resistor in series with the light bulb ?
This will reduce the lamp current and save our battery 🙂
In a few days, I will explain how this and previous version (part 2) works.
Did you also know that we can build these circuits also with the modern Silicon NPN transistors ?
Try it out !
The Ge transistors have other characteristics so we may need to adapt the circuit by changing resistor values.
