You make this mini inverter 

First you have need same important components 

One Bc547 transistor 

One mini transformer from old mobile charger 

And after take one 220 ohm 2wat  resistor .

Simply you make this inverter 

And use anywhere anytime.

Very useful project 

You can use for school project

But this inverter wave line not sine 

And frequency is 150 hz 

Inverter input voltage 1v to 4v 

Output voltage 150v to 220 v

This is circuit diagram
