@growinsmoke easy way to find the how acc is the TC..do a cotton burn test. 420f is scorch temp for cotton.look around youtube. I trust the cotton burn test more then IR probes with DMM to much things affect IR resistance couplers...distance, room temp, airflow. Thats why its not use that much in TC mods as a acc testing of temp.

I do plan on trying that scorch test some time. I have to guess that a wet coil will read differently than a dry one though.
Really, resistance is probably the most accurate indicator we have of temperature. If we could get more precise resistance readings, I would trust that before just about anything else.
Did you get your evil monk yet? Whats with all the holes on the deck?

Ok alpha centauri users, why is this happening?
Try pulsing the button a few times when you load it to melt the oil into the wicks. I've found it tends to splash around like that if I just through a dab on top of the coil and rip it.
On a side note I just started using the 1701 and learned that the ceramic donut cores are made of nickel so they work in temp control mode
. Just ordered a 2.5 ceramic donut atomizer from Divine Tribes to play around with too.

Happens to me too. I think I load to much at a time. I have just been dealing with it. Need like a cap / screen on top.Ok alpha centauri users, why is this happening?
Also up tech has said in the persI forum to try placing the donut on to of the single / dual coil after you load it. I have not tried this yet.

Ok alpha centauri users, why is this happening?
i have zero experience with the centari, but IME with ceramic wicks i have found that when the ceramic is clean it wicks very well. after some use it gets gunky and in turn does not wick as well. and when i vape dabs on gunky wick i notice this happen in my RDAs.
does this happen on a new centari?

I've been running an old IGO-W with Ni-200 single coil at .063 around SS mesh for wick. Having good success on my SX mini at 385 F. Need a deeper well, better wick, more airflow.... but getting there.
1. Is the RX 2000(I think that is the name of the flexible ceramic wick?)the best wicking material for extracts?
2. Any RDA's(would we call them that for our purposes?) being designed for extracts? or any new ones worth mentioning(I saw one the other day with a ceramic cup insert... not sure where?!)

@jpdnkstr... are you not getting the dry coil warning on your SX Mini? i am now eyeing up a IPV D2 that has a YiHi SX130H chip in it. i am not sure if this chip also has the dry coil warning, but i can see that being problematic for myself.
as for the RX2000... i think you mean the ReadyXWick or RXW. its a great wick for extracts. best? thats all subjective. i like ceramics myself. others like mesh or go wickless. hell with a TC device you could even use cotton i would think.
regarding the RDAs... @ArchVape posted about the postless Evil Monk RDA seen here
and ive got one of these Stumpy RDAs coming. should be here tomorrow. the pic is the deck only.

I got an evil monk in the other day and mine had some air tubes that are inserted into the air holes that raise them up off the deck a bit unlike the above pic @2clicker. I don't see anyway to fit a AC dual ceramic cup under the stock cap even after snapping off the air stem under the ceramic cup. 
I got some ni200 24g wire in but the ohms are too low for temp mode with dual coils on my evic. I can get TC to work with one coil but that thick wire takes way too long to heat up and cool down so I got some 26g, 28g and 30g to play with next.

I bet it is probably splattering because I am overloading it. Yes this is brand new. I like the ida of dropping the donut in on top, I wonder how If that allows for more to be loaded at a time, and how hard it would be to take out when finished? I do love this thing, thats for sure! I also noticed that the dual coil seems to eat a lot more oil than the single, and both will melt your face with the pulse technique. Now to decide on a TC mod...

i load a dab at a time. i think the dry coil warning would drive me nuts.
i spoke with another FCer and they cannot even get an errl rip from theirs because of the dry coil warning.
which sucks because the IPV D2 look perfect for me! i REALLY want that mod, but the DCW renders it useless from what i gather...?

If you melt the dab into the wick on vw mode does that eliminate the warning in tc mode?
It's still another step, but that might be what it takes with the more solid concentrates.

@matthend... its a "feature" in the YiHi chips only. so any device with a YiHi chip will have this issue for us trying to dab.
its there to eliminate burning wicks and providing dry hits when the juice runs out. unfortunately for us it means the coil has to be submerged before it will fire.
would love to see a firmware update that allows the user to turn this feature off, but i doubt that will ever happen.
other TC mods with other chips do not have this issue. my evic works just fine. i really wanted that IPV D2 tho... perfect form factor for me.

I ordered a Kangxin Mini VF 50W Mod KX - 50D Chip Variable Wattage Mini Box Mod Temperature Protection VW Mod for $37.99, shipping included, on July 2nd direct from Gearbest in China.
The USPS left a notice in the mailbox yesterday, and my wife is going to try to pick it up. Previous experience is that it's sometimes impossible even with a signed note etc etc. And that's 19 days from order. The alleged tracking number only shows it was shipped to US, not very informative. Granted it's a good price. But it defeats the whole Internet Ordering miracle. I'm not doing this again. It's just too frustrating. I'd rather pay more and have better tracking and contact options. What I've ordered from China via ebay that had an estimated delivery date is a different story, that's been OK.
At least this device will apparently work with dry cotton judging by the video, no dry coil warnings. We'll see. Sorry about the whole paragraph above being a link, nothing I do turns that off.

IT ARRIVED! The MiniVF! OK, first impressions. First, let's glance at my previous adjustable, the HeatVape Defender:
On the board, on the right, is the solder area on the other side of which the Micro USB charging connector used to be. It's tiny and hard to solder back in place. You can see the glob of silicone that holds the 510 connector. So for now, the HeatVape Defender is in museum mode, in the plastic baggies. It's a strange mix of high tech and paper mai-tai umbrellas. So I promised myself something, but I can't remember exactly what, with regard to my next adjustable mod purchase.
.... the MiniVF
So, here is the KangXin Mini VF.
I think it has truly good potential. It feels solid, it has a shape to die for, it handles like a Glock in a jam. All the functions I've tried so far, and of course I'm just getting started, have been ok. You can use titless or titful batteries, in this case a titful Efest, you can see the screwcap sticks out because the spring compensation is only about a millimeter, but that's OK, no problem really, except it doesn't stand perfectly on a flat surface.
The big postive, temp mode aside, is that it's truly buck-boost, meaning you can get that 2 watt mode you might want at times, as it will put out as little as a watt or a volt. At the other extreeme it will go up to 50 watts and/or 10 volts. Here's the manual, vely clir, have the enjoyment.
Anyway, this device looks like a relative winner so far. It's the usual Chinese wonder. Super-cheap components in a clever "borrowed" design. Already I see some easy surgery coming. The threading on the battery "cap" needs smoothing. As does the 510 side. I mean they work, but I don't like sharp edges. The fire button is sticking on occasion. Didn't take long. But I mean, Lawd! $38 shipped from (is it?) Holland (or) China?
It looks like there are 18 hours left on this price (and then 3 weeks' wait). For our purposes here, this little mod with temp control might be excellent, we don't really need day in day out mil-spec reliability. For THAT there are mechanical mods.
I'll be trying the nickel temp modes soon and report. I plan to use it more for e-juice than c-juice, but both really.
I would say if you're handy with tools etc, get one and see.

How does the mini VF regulate?
You can set a wattage, and the mod will output enough voltage to reach that wattage, same as usual. BUT in addition, it won't exceed the temp you set.
The mini VF temp reading seems to be off, I needed to set the target temp higher. Calibrating the temp system is important.

- If you set a very low wattage, it won't even ever reach the temp !
- If you set the wattage very high it will race up to that and then start hunting down and up and down again to maintain as close as possible to the target wattage without exceeding the wattage OR the temp.

Do you notice the power being cut as it hits the temperature limit? Sometimes with my kanger subtank I can feel it pulsing on the inhale. Something like 2 pulses a second, 50% on/off. It doesn't really bother me, but I can make it go away with more airflow or a slightly lower temp setting.

temp limiting is def the future of vaping errl.
We should get a chart going listing mods, atomizers, c-juice mix ratios, temp, watts, etc for best performance.

This is a very interesting topic IMHO. I can see the display show the "hunting", but haven't felt any pulsing on the inhale. I've built a lot of computerized "closed loop controllers" for motors on elevators, cranes, aerial trams and so on. You can design a system so it smooths out the seeking.
One way is smoothing on the feedback loop, sort of the equivalent of a mechanical spring, so it can't hunt too fast or too aggressively. Like if you're in the shower and the water gets too hot, you back off on the hot water tap too fast and it goes ice-cold, so you turn the hot water up and now it's too hot. You've overshot the setpoint. You get into an oscillation hot-cold-hot-cold unless you limit the excursion and the rate of change - that's called feeback smoothing.
A good design also incorporates feed-forward. By learning from the previous cycles and measuring the temp on the uptake, before correction is applied, you are applying "feedforward" control in addition to "feedback". A good "PID" or Proportional Integrative Derivative algorithm can achieve a very smooth control. A modern elevator doesn't jerk as the speed is varied. A good cruise control doesn't pump the accelerator. A good heating/cooling system doesn't turn on and off every second.
The Mini VF seems well-done that way, a decent PID controller. The break-even on my 0.11 ohm coil with 95% VG e-liquid is around 12 watts. If I set the wattage to 12, with a moderate airflow, the display is stable. With a higher wattage setpoint, if I listen on the drip-tip I can sometimes hear it pulsing the coil at about 10 cycles per second. If I set the wattage to 50 watts, it has to fluctuate a lot, it will slow down at times to as low as 2 cycles per second, but even then there's no irregularity in the vapor intake. It seems like a waste of battery above 25 watts or so, I get no more vapor, just more hunting. The odd thing is that sometimes it's so smoothed out I can't hear any hunting at the drip tip, even at 50 watts, it rides it like a greased swan ;-) As the coil dries up, it hunts less.
