If you have the possiblity to raise the voltage the resistance doesnt matter, but if you only have something like a GP every millivolt countsThat said, I'll be making an R only coil for my BB. What I lose in power I can make up by cranking the volts up.efficiency be damned.

@Konstantinos: I give up for now with the V2 in the SnP, this tank is more than tight
I will try again as soon I have new O-rings.
for the moment I use it with the V1, maybe the V1 is a little bit complicated, but I now him now for a long time and nothing anymore can surprise me - and its still a very good atomizer![]()
As a EE, I like seeing people make circuit diagrams. That said, I'll be making an R only coil for my BB. What I lose in power I can make up by cranking the volts up.efficiency be damned.

I have a BSEE, too...and a billet box. Missed the first run of diver V2's, but will order one when they are available on Monday.
This is not my first atty with a ceramic cup, and I had the same theory as you. But there are two other factors to consider. 1). Higher voltage creates more heat, so more chance to melt the insulators. 2) the wire thickness...0.2mm is the thickest you can go and still get the cup seated without breaking it, so 32awg. It's about 14.5ohm/ft, pretty high...depending on where your sweet spot is on vaping, it's possible it might not work as well in real life as well as on paper.

You're completely right about that. But my experience with the diver V1 with 30 AWG all R wire micro coil leads me to believe that it should work well. I really need a welder. 80% of it would be the fun of welding.

The ceramic big tolerance (~0.3mm) was the reason for the delay of a week of V2 release![]()
The pin on the diver may be a slightly smaller than my Sophia, thus allowing a thicker wire. The uncontrollable variable in all this is the ceramic. Making industrial ceramics is a bit of a black art, as they are made large, and fired to size. The diameter can vary a lot, both for the interior positive pin diameter, and the external ground diameter. When I was in the semiconductor business, we sourced mil spec ceramics from a Japanese vendor, and they were so expensive, because of the variances of the ceramics even from within the same firing. Needless to say, these cups are far from mil spec...

Happy day. V2 just arrived. Will give the provided coil a try.![]()
Happy Diving finagle![]()
Konstantinos, I hope you have lots flangeless and 35mm tubes coming up shortly. I just got lucky and snagged a piebald BB earlier today. Now I need 2 divers.
As did I, can't say no to mother-of-pearl.
Just wanted to put in a quick word. Stock coil is pretty loose. Had to double up the NR wire negative to get it to hold contact. Set it up in the BB and she fits like a glove and gives off great flavor. I'm betting it'll do even better with a micro coil and cotton.

You mean between the ceramic and side wall?

Correct. It was not wanting to stay put. Also my center pin wasn't super snug. My V1 was much tighter. But this is all just fine. Working on a 30awg micro coil right now.

Better too loose than too snug. I went thru several ceramics that would not go onto my Sophia without breaking due to the positive pin hole inthe ceramic being too narrow.
