VaporShark rDNA

I have a copy of the original data sheet fro Evolv and its the same as the one on their site now. AFAIK it has always said .1 min/.4 typical.

Maybe Busardo is having too much eggnog???

Looks like they did bump their typical ohms to .4 That would be hard to get to. Wonder if these guys actually build their own coils? For me to get to .4 would require a lot of wraps with 32ga and probably would need to wrap it directly around the rayon. Forget about .4 on a dual build. They recommend up to a 1.0 build. How could you even hit that? It would have been better if they lowered the target to .1 Then you could use 26-28ga for easier builds, and get duals with 30ga. Seems like all it would take is a software fix. Maybe the TP doesn't play as nice with lower gauges. It would be interesting to hear from them how they hit the typical .4 target.

Funny. I have looper in one of my lemo too. Heehee

The lemo's been my single most consistent performer so far.

After about an hour and a half it went haywire: voltage mode...hold the fire button, back to TP...rinse, repeat...checked the 510, no love...back and forth V to F.

I had a problem Lemo doing the TP to V dance.
Thought it was a 510 issue.
Finally, disassembled everything and soaked the parts in alcohol.
I think it was some oil in the positive block threads.
Has been working great since the thorough cleaning.

I did not intend rinse, repeat literally. ;-)

Dammit Kiwi, your gonna end up making me buy a Lemo.

I'm surprised I still haven't gotten into your head yet!

My best, most consistent performer has been my orchid with 15 wrap dual coils around a 2.4mm mandrel ... Measures 0.09 ohm, 410 degrees with 20-24watts

Rock steady and has been the same coil for 4 weeks! Just change cotton weekly

A couple of days ago, after 21 days and 80 ml my perfectly performing main vapin' Russian 91% fell back to voltage mode occasionally.

Open it up and this is what I found. The rayon wick was still completely white except for a few loose specks of coil gunk.
The coil was not bad, less then 20% gunked, maybe 15%.
The coil was slightly arched and there may have been minor contact, I couldn't say for certain.
I was able to tighten the coil terminals 1/2 turn each. They were tight 21 days ago.

Groomed the coil, dry burnt, re-wicked and it is functioning perfectly again for two days now.
Juice was an RY4, I'm very pleased with the run but disappointing that I can not say what exactly caused the resistance to vacillate.
The screws were pretty tight already, was it the screw contact, the gunk or both. FWIW I believe the gunk caused the coil to deform.

Gunk, I be watchin you!

 

[Flyfishsick]

when you re-wick are you dry burning the coil? do you up the temp and dry burn? or move it out of temp mod and burn? i was under the impression the nickel coils did not like to be dry burnt?

 

[TheKiwi]

Lawl. I just turn off TP and pulse fire it. Sometimes I straight up dry burn it the same way I do for kanthal.

I thought about ordering another one [Kayfun V4] but decided to see how the first one works. I don't think I'll like it enough to get an authentic @ $180 though.

Do keep us updated on your experiences with it.

I can confirm that. (That the typical resistance with temp sensing wire was .4Ω on previous data sheets, not that Busardo had too much eggnog.) Two separate downloads of the Evolv datasheet still in my download folder, one from Oct 24 and the other Nov 9.

I've been really close to pulling the trigger on a lemo a couple of times and Kiwi isn't helping any, I'm more interested in the K4 but 180 is too steep for me and I doubt there will be a good clone for a while. At least I've ruled out the erlk for now, too many mixed reviews.

 

[freedogg]

I have a K4 and a couple Lemo's.

There is nothing wrong with the Lemo's, especially at 35 bucks!!

The lemo is an awesome tank, actually prefer it over my authentic russian 91%. Have to say that the flavor is kinda muted with the airflow wide open though.

 

[TheKiwi]

Yeh yeh.

Also, flavor is going to suffer whenever you open up the airflow, there's just no way to escape that. Buuuut you can always overcome it by cranking up the power. I get extremely get flavor off my lemo. Omnomnom

I've barely touched a Kayfun since getting the Lemo. I enjoy it wide open.

Yes I'm dry burning both in temperature limiting at 600F and out at > red hot temps.
I don't see any problem dry burning coils. Ni200 is not code for use in pressure vessels that operate at greater than 600F I believe this is where the idea comes from.

 

[KTMRider]

Same here but I don't let it glow red hot for very long. Just enough to burn off the crud a little at a time. As soon as I see it start to glow, I let off on the fire button and blow the coil to get the burning crud off and cool it down.
