I am making this for my science fair.What I wanted to know was that
1)Which other mosfets can i use instead of IRFP260.Can i use IRFP540N or IRFP450N, IRF3205N or IRFZ44N.
2)Icant find 3.3nF capacitor
3)Any modification to make it fool proof such as installation of certain element which can protect mosfet btw I will heat sink it and keep a water reservior nearby
