Most of the people responding in this thread are very savvy with TC.

I'm not worried about you guys at all.

I worry about the ones who aren't.

Don't get an SX then they don't auto sense at all.

In this case......for those people......that's better as it's LOCKED into a mode and cannot switch to blast a ton of watts through a ni or ti coil.

Not sure if it comes out of temp mode if you have kanthal I didn't bother to check, but they must do.  

I don't know about the Evic but with a DNA regardless of the resistance including changing resistance the all the DNAs have real time power regulation and will only put out the watts required.  I think you are confusing Volts with watts, at set volts that would be a problem, but not with set power as resistance is part of what makes a Watt.  I know that the IPV2 YiHi board did not react to changing resistance and judging by the oscope traces the SX Mini M has a test pulse between voltage blasts to check resistance so I am not sure that YiHi have done real time power management yet. Does Phil put this on the lazy box and change the resistance while firing?

That's true but a TC mod is IMO advanced, if you don't understand them you shouldn't buy them. I've said this many times in here, some agree and some take it to heart. 

Its a a bit like newbies asking about drippers and some advising get this and bang a 0.1 ohm coil in you'll love it, bit of a step up from maybe an ego for example. Good idea or madness, you decide !

I think in most things there's simple and then an upward curve of specialist items and IMO it makes to sense to work your way up and learn how things work.

I have a shot gun licence for a specialist reason but I've never used a standard shotgun. There's nothing stopping me going and buying a standard shotgun and blasting about with it but that's not something I'd consider without proper training first.

Has been his way with temp limiting since the beginning, he sat next to Brandon from Evolv and was told the tempored nickel was easier, but come the DNA40 review he forgot and had a good moan about building with standard annealed nickel.  He then renamed it temperature guessing because the YiHi was so different to the rest.  He normally gets there in the end and changes his mind quietly and sometimes admits he was wrong as we all can be, I can remember when he had his genesis epiphany, he hated them for ages before someone built one for him.

I remember that video...

He basically did a whole video of 'ok now I get it'. Lol.

PBus has never been the sharpest with TC but it was the battery parts of this mod I'm interested to find out. For that PBus is normally the man.

Itching to watch the review but downstairs with Mrs Tom at the minute. Will go to bed soon and see what he has to say

Case in point I thought I should watch the video and around 20 mins he has a new force meter and it reads higher than theo old one so he s ordering a new one, didn't think to go down the post office and push it into their calibrated letter scale, put a weight on it or use the kitchen scale.  I am a PB fan because he puts a lot of effort into doing things better and not trying to slag him off we all do silly things.

I am now and I never wanted one of these, they look nice, just not for me.


Greg I think it should be easy for people using nickel coil heads, advanced for rebuilders yes, but should be easy with say a sub tank with the right head.

He also failed to notice the measurement was in newtons not Pounds!

I don't disagree with the sentiment VB, I'm just suggesting the onus is on the end user to understand what they are buying and how it works etc.

Vaping is not particulary special, you can buy lots of stuff in many fields than can do you damage if you don't understand it.

i remember a vendor being cautious regarding selling stock Ni heads when they first came out. 
Nothing to stop a user buying stock Ni Subtank head then using it on a mech for example !

The only surprising thing is that no-one has done this and made it into the papers already!

No adjusting down!!! Like an very old digital watch where you have to go all the way round again.

He has got the jumping out of temp control all wrong, the watts won't matter (unless you set them to something silly) they will cause it to act as a non temp sensing mode and not cause any nasties in general, but they could if you take short cuts designing your board and software. The problem is lack of real time power regulation and he goes on to tar the Evolvs with the same brush and all of them since the Darwin have can not do what he described.

What is real time power regulation: using the product of current and voltage to control watts.
What do other mods do: measure the resistance and pick a voltage to fire at, so if the resistance changes the wattage changes because the voltage is set.

(This is also why I say the SX seems to do temp limiting in a silly way IMO and not because I am an Evolv fan boy)

Did you guys make it far enough into the video to see the results of the temperature tests?

Yes, I wrote this after watching it

PB is blaming the wrong part of the process, it would not matter if it had real time power regulation, but it seems to be one of the devices that intermittently measures resistance to regulate power I have been pointing this out for at least a year but just get people shouting back how good the IPV etc is so don't often bother.

I meant the bit where he puts the temp sensing probes inside the coils on the Evic and a dna40 and an sx350 to see how close they are to hitting the temperatures the mod is set for.

Yep, seemed very silly as the max temp will allways be on the coil and the probe wasn't touching the coil.  As for the SX being almost as accurate as the DNA40 letsavit and I have had a very different experience as IIRC PB did when he reviewed the SX.

[Deleted]

It was at the higher wattages that they all go way out......the SX and the DNA40 were way over and the Evic chip way under

From a usability, safety.....or any other perspective.......is is better that it's over or under?
