I posted this in the modding forum first and probably should have posted here anyway each time I build a mod I learn something new and reading this forum. I love building mods it's in my blood now,I have no electrical experience but I can read a picture if that's the right way to put it anyway I got the cover on e-bay for 2.89 I think I'll post a link if you want (not to good at posting links ) got the 5 volt regulator and switch from madvapes, I have made vv mods and I rarely use them but my sweet spot is 5 volts so I'll be making only 5 volts anyway here it is .
