I was thinking 28 g 8 wraps on a 1/16 drillbit , is this a safe build ? With sony vtc5 s
8 wraps of 28 ga on a 1/16" should come in right at 1.0 ohm.
And yeah, the issue is battery safety. It is super important to have a good grasp of Ohm's Law anytime you start building coils, really at any ohm.
Sub-ohm just gets a vaper closer to the point where a mistake or misjudgment can result in a battery short and runaway thermal event. Real low sub-ohm can get a vaper right up to the edge.
