the mystery is the resistor connected under the capacitor take a look of it,.. thats the reason why it drops 5v dc without regulator. (y)

Robert, just for preventing any likely confusion, please read above the word “drop” as “output”…

This always depends on the input data Robert. If this 2,2 μF cap is connected at 230V/50Hz mains, then for 24 Volts drop it will let 158mA to pass through it. If the same cap is connected at 110V/60Hz mains voltage, then, for the same voltage drop of 24V it will let 89mA to pass through it. These above are the theoretical maximum current values for this cap and for the given voltage drop of 24V at the output circuit.

You are always welcome Beh. This circuit that looks strange for the time being will lose its mystery after deciphering its secrets and will become a trivial matter thereafter!
Thank you for your wish and recommendations about confronting the flu issue as well. I always take care of having my hands clean all the time, especially when being ill of flu. This is important in such cases indeed.

A 2.2uF(225) should give about 24V 100mA output.
