Just look at everything on this
mod forum. I went through it and have sucessfully used hints and tips to make 5
mods so far. I will be posting them soon. I have made everything from standard to a bottom feeder and even one with a voltage display. It takes alittle searching but you can find a starting place and once you start your imagination is the limit.
look up the nico drip v2 that has a link to the photobucket of the making I used image 29 to get the wiring down which is the hardest part if you are not familiar other than that everything else comes down to imagination and the space you want to cram it into.
Good Luck
