SXmini M Class (TEMP CONTROL)

[tchavei]

I jumped through the video (it was boring, sorry) and got the part he burned that cotton to ashes. I didn't get though if it was because he forgot to set the base resistance or was using a full contact coil?

all of the above and them some I think....eouldnt be suprised if he was actually using kantahl..lol...except that first coil would have weighed in a 25ohms...

My SX arrived this morning via FedEx... The two REO's (Avril and Camila) are chatting to the new SX and getting to know each other!

Lots of questions to follow after I have read the whole thread! ;-)

I just watched your vape Mail Baby! video nice. Particularly liked your buds at 10:35. https://youtu.be/lcZ2Y0vlWuA?t=632 lol One thing I'll mention is while I agree with you on the battery cap and I wish it were designed differently. I've used my thumb to remove and replace it since day 1. If you cant you may have dirty or gritty threads. I've heard others post theirs were dirty but mine were perfectly clean.

Not so sure about that, as far as the SXmini is concerned. What I think it's doing is always applying the correct amount of voltage necessary to apply set power per second. So it's not applying MAX voltage, but instead always applying "correct" voltage to achieve the given Joule value. So set at 30J, for example, if the coil starts at .11 Ohms at ambient temperature, it will apply 1.82V for a value of 30W, which will heat the coil, and the temp will rise along with resistance. It dynamically adjusts the voltage to maintain 30W. Mine usually reads around 3.02V at the end of the fire cycle, which would suggest that the coil fluctuates in value from .11 to .3 ohms as the temperature of the coil rises. You can see it at the very beginning of the fire cycle it is a much lower voltage than what is displayed when you let the button go.

I've also come to the conclusion that the temperature isn't so much a measure of the temperature of the coil as it is the temperature at which the juice vaporizes. We often see the temperature stall out on the SXmini, and never reach our set temp. This is the vaporizing temp of your liquid, where it stalls. Once all the liquid is gone, the temp will rise up and hit the temp limit that we set, and the voltage will get shut down. If we were heating water, for example, the coil will never get hotter than 212F until all the water is gone, only then can the coil get hotter than the water. We can apply more power to the coil, which won't effect the temperature at which water changes state, but WILL effect the rate at which the water evaporates. So changing the Joules allows us to vaporize the juice faster / produce more vapor. The temp that the juice vaporizes stays the same.

Geek out on that

Worth repeating

Lots of overnight discussion on joules/watts/etc. How does it work? Good question I think. Yihi engineers know where I can only speculate at this point. But it did peak my interest in searching for an electronic metering device that actually can measure joules. I found a volt meter, an amperage meter, an ohm meter, and a watt meter rather easily. Any of these meters can easily measure what they are designed to measure. I am having trouble finding a joules meter. Maybe some of you engineer types can point me to such a meter..... thx

Short copy about joules I ran across.... ironic how nickel is mentioned...:

James Prescott Joule analyzed the nature of heat, and established its relationship to mechanical energy. His efforts had a profound influence on the theory of conversation of energy (the First Law of Thermodynamics). He collaborated with Lord Kelvin on the formulation of the absolute scale of temperature, and carried out extensive research on magnetostriction; a property of ferromagnetic materials that makes them modify their shapes when exposed to a magnetic field.

Joule was the first scientist to identify this property in 1842 during an experiment with a sample of nickel. He established the relationship between the flow of current through a resistance and the heat dissipated, which was later termed as Joule’s law. He is also credited with the first-ever calculation the velocity of a gas molecule. The derived unit of energy or work, the Joule, is named after him.

OK should have my M middle of next week. I was reading the manual and it says optimal is .065ohms. According to Steam Engine with 28awg NI200 that is 6-7 wraps depending on leg length. I will be using a Kanger smt. So if I go 7 wraps it should work out ID3mm. Does that sound right. Then if I set it at 20-25J 410F I should be good right? I'm planning ahead trying to figure it out. Not sure on the J setting. I don't want it to ramp up quickly but is 20-25J enough? Also if I understand right you trap it on the opposite side of the screw as with Kanthal so as not to pull the coil correct?

Thanks for that! Will clean the area and give it another go! ;-) Appreciate the feedback!

Try searching "Joulemeter" one word. Not a high demand for them I'm sure but there's quite a number to view.

THX.... not much time this am but quick view of one such meter seems to input voltage and amperage and apply a load then calculate the joules as a result... on first glance it seems to use calculations to convert mechanical energy to joules.... will look further later in the day...

thanks again for the link... also a lot of software to calculate joules... mostly from microsoft...

Why can't you use the onboard joule meter? If you set the unit to say 30 joules and hold the button for 10 seconds, the meter should record 300 joules (in normal mode). In temperature mode it would register the total amount of joules used taking into account the potential throttling to hold the temperature?

Or are you trying to measure something else?

So when I'm travelling at 120km/h for a few minutes, I have no idea what my speed is because I haven't travelled 120km or during an hour?

My TV states 45W/h so I know that it will consume 45w per hour. Does that mean a
That if I turn it on for 15minutes, it doesn't use 45w/h?

I actually find the opposite to be confusing ie a mod set to 30w will use 30w on each fire press? Or during the 10 sec cut-off? Or maybe each second? If it's the latter, the correct designation should be 30w/sec which is... Wait... 30 joules?

I agree with you. Joule's makes more sense to me. There is not any magic pixie dust regardless if it's watts or joules as they are both a unit of measurement. The key is in the correct usage and implementation of those units of measurement. As far as I'm concerned the community reviews and consumers reporting in these forums are making their opinions loud and clear as to which methods have been implemented the best.

I will say that VLAD1 and TCHAVEI, i agree with your theories on the workings here. I just picked up my SX Mini M yesterday, and i cannot believe how great this thing is. This is my first experience with NI200 wire, and temperatures and such, and it is amazing. Just the fact that my cotton never burns is worth the money i paid for this thing to me. No more dry hits! And the vape is the same every time i push the fire button.

 

[Fir3b1rd]

I can't help but think everyone (myself included) is thinking wayyyy to much into this. Maybe leys try looking at the numbers not the vocabulary.





To forewarn. I have no measurements and no data to support the below.


This is only based on experience and using the mod next to another well known Temp Limiting device


in a few days we will all have charts to look at and come to an actual conclusion.





But I think what they did is so simple it's brilliant in a way.





Why would we have 60w in "power" mode and 50j in "joules" mode?


What if they took 60 and divided it by 50 then applied the unit joules to the product?


We would have 60/50=1.2 joules



Again I can't prove it I have no evidence im totally throwing a taco at a wall on that but it answers a whole lot of questions in my mind

And to be honest the vape is phenomenal and of that's all they did I wanna shake their hand

Well I'm considering buying another SXmini m. If I do I'll ask for some extra pixie dust and unicorn farts and I'll send you the pixie dust.

Am I missing something or is everyone just making this a lot more complicated/confusing then it really is?
There is not much confusion or discussion about the Powerful+/Poweful/Standard/Soft modes, why the Joules? Its just another user variable setting to fine tune your vape as you like.

I set my temperature control to 420 degrees. Whether I have it on 50J or 40J or 25J, my SXmini gives me a constant/consistent vape at 420 degrees. The Joules (or even if it was watts) is irrelevant to the vape and heat and temperature. Just how fast it will get to the 420 degrees and start throttling.

Since we are talking about cars as an analogy... Car #1 goes 0-60 in 10 seconds. Car #2 does it in 5 seconds. But once they both hit 60MPH it doesnt matter how long it took to get there, they are going the same speed ---- when my coil reaches 420 degrees it doesn't matter what my joules setting is (as long as its high enough to maintain that 420 degrees).....I hit the fire button and a get a 420 degree vape.

Although I find the analysis of the how and why of this chip's function fascinating after a week of use I find the what to be more salient. 45 ml of juice, 3 different toppers, single strand 28 AWG and twisted 30 AWG from 0.08 to 0.14 ohms,, juices as clear as Snakebite from Virgin Vapor and Forgotten Memories from Alice in Vapeland to juices as gooey as Carmel Pear from Jimmy The Juiceman, organic ball cotton and KGD...and always a satisfying vape with zero dry hits and zero scorched wicks. I stripped the wick from a Kayfun v4 after 3 tanks of use, rinsed it off, and it looked exactly as it did when I first built it. I'm using mine at 420F with a variety of J and power settings and it just plain works. If you are considering purchasing this device and functional implementation of temperature control is the deciding factor, my personal experience is that it works.

And in the end, that's exactly what matters.

I don't know, maybe I'm just shy from previous bad experiences but every time I see these strange philosophical 'potential' problems I can't stop thinking about an highly elaborate ECF rule #11 infringement.

I don't know, what's so fundamentally wrong with using joules? Doesn't it vape the same? Does it hinder you reading the screen properly? Does it make you burn your wick? Does it, somehow in some way diminish the pleasure of the vape?

And now I broke my promise not speak of this anymore... Dammit [emoji14]
