Anyhow, I hope the "educational kit" is fo adults, I would hate to see a kid working with mains voltages in a kit. Total agree! Vishal, what you are doing is very dangerous!! Why? Because thousands of volts can be present on mains lines, and this not only during lightnings! Your parts can hardly withstand these high potentials and involved fast voltage rise times and you don't use any protecting parts!! I recommend always the use of transformer isolation, when handling with mains voltage!!!!!!!!!! There are so many traps which you can fall into and can make you die, that any direct contact to mains should really be avoided, avoided, AVOIDED!!! Use a wall mart safety class II transformer (safety transformer) and use the secondary voltage for experimenting, as it is shown in the link I recommended earlier:  Kai |
