Hi, In this Video I tried to explain how a coil gun works and what may get wrong in process of making it.
The gun I made today is pretty harmless (if you don't shoot in your eye) and low powered but the principle of low powered and high powered guns are almost similar. and my low powered gun will work greatly for demonstration purposes.
Note:-
The Circuit used in this video is not perfect, For Example if there is no bullet in the chamber then the Voltage of the Mosfet gate will drop very slowly because our optical sensor will not ground the charges. That Results in high Drain to Source Resistance and that will Heat Up The Mosfet very Quickly due to voltage drop across it and kill the Mosfet.
The Easy Solution of this problem is you can use Two way Switch (Where One way is connected To Ground) but if you push Button for long period of time then this will not work.
Thanks for Reading
