High voltage generator

This is a fun but really dangerous project, do not try this at home I give you the list of the parts but it's just as informations !

obviously you can find cheaper components !
It work with just two AAA batteries ! You just need few components as explicated on the schematic !

If you want more power you can replace the two AAA batteries by a 3.7V battery, holes for charching are predesigned !
