SXmini M Class (TEMP CONTROL)

[Hitcat44]

It's All Good
So far the 0.2 range is suiting me. Might try around a 0.1 with 26 ga on the STM rba Base when it comes in just to test and get a good Comparison.
Thanks again.

30 ga Twisted? Man I'm twisted enough. Any more and ima gonna Snap

Stainless Steel has been around and is used commonly as a wick (mesh). It can be used for heating a coil if desired.

Per posting on reddit..

I had a metallurgist in a top defence contactor break down some 20awg gplat haywire. I just received this email. : electronic_cigarette

Well aware of SS as a mesh, I use it in my Veritas, however, the 316L/317L wire for use in a coil setup seems to be coming back around, Ive heard from several folks who are testing it with temp control using another method for measuring temp aside from resistance change from cold to hot (Stainless Steel doesnt change resistance in a measurable way when heated).

I mentioned it because I thought I saw someone else mention it in this thread, could be mistaken, I hadnt gotten much sleep.

Most Stainless Steel has more carbon in it so you wouldnt want to heat it higher than 425 degrees, that is why you want to use low carbon (denoted by the L after the 316/317). Different variants of Stainless Steel (denoted by the number) will be more or less usable, depending on the variant, SS can become very brittle (if my memory serves, sigma phase?) when heated, some variants have a tolerance only to 425 degrees while other variants can tolerate up to near 600 degrees before there is a composition breakdown.

Anyway, very curious how it will be used in a temp control mode and also curious HOW the temp is being measured...

Looking at their web site I see that they are out of 26ga Ti but it would have been $9.95 for 35'. They do currently have 24ga at 30' and 28ga at 40' for the same $9.95. Maybe all the Ti vapers have already hit them up for the 26ga wire which appears to be the sweet spot for coil our Ti attys.

Just got a Message back from Phillip at Unkammen. The 26 ga was received by them and is back in Stock as of Monday the 6th.
Good to Go so Order Up.
Also, I told him they are catching on as a Reliable and Proven Source of Ti for the vaping Community and are greatly appreciated.
He thanked for the kind words and the Business and Support from Us all.

Sorry guys. I tried searching for an answer before posting.

Received my all black mini yesterday and noticed I have a gap under the 510 plate like some have noticed. I have some serious OCD and the tanks sit at slight tilt.

Anyone know if the plate is press fitted so maybe I can hammer it straight?

Or anyone come up with a solution on how to eliminate the gap?

Thanks in advance.

errrrr...yihi recommend 0.065 as the optimum for TC vaping....you may be reading the wrong spec sheet?!?!

Yeah I have read nothing about recommended or upper and lower limits from YiHi which I think is kind of a bad move on their part. They put the test firmware out but no instruction. I d/l the upgrade and have it on my computer and from what I have been getting on this thread it works OK depending on the atty. One thing I have been wondering if you do install it on your SX does it make any changes in the way the nickel settings work or do they still work the same.Has anyone given any feedback to YiHi on the firmware. Seems like it is kind of hush hush on how to use it but I have seen people using it. The thing about the Ni firmware is you have a limit of .3ohms and I have seen people using.4+ which won't work on the Ni setting. I would load it on my SX's but want to make sure that it doesn't screw up the way it works with nickel which I am very happy with. Planning on .24 on Ti from others recommendations on the STM. Is there a spec sheet for Ti I haven't seen it if there is. It's kind of a shot in the dark.

 

[2legsshrt]

Oh and you can get 170' from Vape Mesh. You buy 4 10meter rolls get one free thats 170'. And a friend of mine said that the company has been in metal products since way before vaping even became popular. That's more then I ever will need but that free roll is awfully tempting. And I understand some other countries get their stuff from the US but Vape Mesh makes their own. A friend of mine told me that he would trust anything metal made by them.Many places get their stuff from them. And their prices can't be beat. Thanks for the tip QM

 

[Hitcat44]

The same RDA w/Ti Build that is Quirky on the Ti Profile is working like a Champ on the Ni200 Profile.
From that, I can attest that the Test Firmware upgrade does not skew or corrupt the SX Mini M when used in the Ni200 Profile.
Upgrade at Will without trepidation.

 

[2legsshrt]

So what do you guys recommend about loading the new firmware on the SX. If I do it will it screw up the nickel part cause I love the way it works but if it makes no changes there then no reason not to load it up.

errrrr...yihi recommend 0.065 as the optimum for TC vaping....

From what I have seen, the spec sheet mentions 0.065 Ohm as a typical resistance for TC (with Ni200). Typical, not optimum. In fact, I see no reason for any "optimum" resistance in the supported range. "Typical" could mean something like "ordinary", e.g. 26g, 7 wraps, 3mm id, which results in a 0.065 Ohm build with Ni200 (and 0.33 Ohm with Ti). I would not interpret too much into this.

this has been discussed ad nauseam earlier in this massive thread. 0.065 came from yihi as a response to an enquiry as far as I remember. Thats why I said it.....there could very well be an optimum range for the best temperature control dependening on their implementatiuon of it, chip design, feedback algorith etc....

 

[dr3d]

Sorry...I'm new to Ti and I forgot the recommended resistance range on the sx mini (and lazy to scroll back the pages [emoji14]).

Can anyone recommend a decent gauge (and optimal resistance if possible) using Ti to build dual 2mm - 2.5mm diameter coils? I have a UD Zeph (and Billow v2 on the way) and building it with nickel is somewhat PITA

Both my Billow 2s are built with 26g Ti on 2.5mm with 5 spaced wraps. They both ohm at .13 and prevent me from even picking up my other atties.

I think the static resistance of the atomizer is more important to the optimization of temperature accuracy than the apparent resistance of the coil. I'm just about ready to measure static resistance of my favorite atomizers to see what differences that makes as soon as some silver wire arrives to short the posts.

There's quite a bit of discussion about static resistance and the potential consequences at TheBloke's thread

I am liking this Ti ... I notice I am getting about another 4k-5k joules per battery charge, I am using 26650 battery though so 18650's might be different, I was usually at about 48,000 to 49,000 joules now I see about 53,000 joules on a charge.

I am using 26ga spider silk Ti ... about 3mm 5/6 wrap though it might be a shade bigger cause this stuff is a lil springy

I am also still using the old firmware that doesn't include Temp Ti option since I am using my own mod, will be wondering what the update will prove to do once I can actually download it into my mod since they have yet to release a firmware for the board itself.

Duane,

I took a copper penny buffed it with a soap Brillo Pad until it was shinny and then used the penny to short across the Lemo 2 terminals. On my Atty (cheapo ohm meter) I got a Zero reading. I didn't try it on my SX or Flask because I assume I would just get a "Resistance Too Low" message. But as I am telling you about this I think I will try it anyway.

Just don't thing those $20 dollar Atty meters are all that accurate. I know, I know big surprise. Cheap is as cheap does or something like that.

Not all Stainless Steel is the same. For example, 317L does have a usable TCR provided your accurate to about a milli-ohm:

Other Stainless I believe is as bad as Kanthal.

I take it you mean a final firmware upgrade because they have released the test firmware on their website. Sorry I misread that you mean an upgrade for the board itself not for the SX.

Armed with all this knowledge, you should go and beat up the Ti experts in the other sub group... and tell the where they can go.. Unkamen

You mean that GG cult thread?

If we all put all our extra wire together we could probably encircle the earth. I have about 1000' to get us started.

1000 feet?????
Some quick math...... 6" to make a coil. 1 new coil per week = 26 feet per year.
1000 feet = 38.5 years worth of coils.

I'd forget about titanium for a while if I was you. By the time you run out of nickel, they'll be vaping with wireless technology.

The 3rd STM arrived today from the HK along with some Ni200 OCCs.
Loaded her up, wet her down, sighted her in (sync'ed), pulled the Trigger and let her Rock.
No issues whatsoever. Finally settled at 30J & 365* F and it's settin 'em Up and layin 'em down nicely (50/50 mix).
The Ti Test Firmware definitely isn't quirky or twitchy using Ni.

That being said and done, the El Cabron has been reassigned back to the Mechanized Division here at Ft. Vape where he belongs.
Anxiously awaiting the 26 GA Ti on Friday to outfit the Lemo 2 and let it send some Rounds down-range.
Will build an STM RDA Base at the same time to lay in Reserve.

Thanks again to all you Ti Commandos for dragging me along for the ride.

Oh yeah, when ya think this "Wireless Vape Tech" Stuff will be ready to Beta?
Will we need to recruit some IT Guys to spearhead the R&D learning curve?
