How to make Step up booster 1.5V to 3V 5V 9V 12V

[@madhusudangupta3661]

You claimed for multiple voltages from the circuit! Why did you fail and disappoint the poor viewers. Bad manners. There is no voltage measurement. What is the purpose of not proving the voltage. Why is Zeher not used? Hope you will like to respond.
