Just Thought that I would share a pic of a Mech Squonk mod That I made a few years ago built on the MOSFET safety system. It rocks a Squonkalishious! It is pictured with a small atty. It's just a tiny frankenskull. BF Squonk and can run single or dual coil but obviously not super low in the ohm department. However that just means that the batteries last longer...
