SXmini M Class (TEMP CONTROL)

[Quantum Mech]

Thanks. This is more general temp control, but why is it people say they don't like the Ni coils? Is it just tough to build or is it a flavor thing? I'd probably be going Atlantis, with the Ni prebuilt coils.

I could at first taste something with Ni200 that was not there before with kanthal A1
Was suggested I clean my wire prior to building which really helped & thought flavour had improved & was happy
But then once I tried Ti I realised there was still a taste with Ni200 even after cleaning

Ni is very soft so smaller gauge wire is a challenge but not too hard
I was using 29awg & the only real issue was holding the coil in shape whilst wicking
At this gauge I met the resistance ok but those that like thicker wire will struggle to fit them in a lot of rta's

Many are happy with Ni though & until you try Ti you don't notice the metal taste was there if using cleaned wire

So on reading this Rebel

I now get watts in equals watts out statement by HolmanGT

And see the 2A draw at 8v is 2A from each cell even though they are working as one cell

But this is half the amp draw per battery when working alone at 4A

So why does the mAh not increase [double]

George was definitely right in his very earliest of statements on this subject saying not to get involved in this again ....

The capacity is the same in series. You are doubling your run-time by drawing half the current.

Also, does any US vendor stock them? Maybe one with an ECF coupon code?

Don't know about coupon code but vapinart sell them
Its where I just ordered from & got an all black one which are still in stock if you like

[Taowulf]

Yup! But at $199, it may take a few more. How much longer do the attys last in Temp control mode? Is it realistic to expect I'll go through a lot fewer attys?

I assume you are referring to prebuilt nickel TC coils? No idea, never used one. I will have some next week though to try in a Subtank Plus. I've been troubleshooting with my Lemo, made a thread about the issue I was having and how I fixed it...in the last two days, I have rebuilt the lemo and lemo 2 I use for TC multiple times. But not because they failed, I was either experimenting or trying to fix a problem that ultimately was solved elsewhere.

Thanks! Now I just need the courage to click checkout. Usually takes me a little while. Maybe a drink or two.

There maybe some reason why e-cig devices are very inefficient? I don't know.

The largest inefficiency in an e-cigarette is likely the atomizer itself. To quote a patent application: "While the prior embodiments of e-Cig designs may vaporize approximately 4mg of e-Liquid during a puff, the heating coil heats the entire wick during the puff wherein the heating coil may hold 100 mg or more of e-Liquid." See Int'l Patent App. No. WO2015028891. That's a lot of energy being wasted as heat. In addition, you can have a lot of inefficiency as well in the vaporization process because of different boiling points and recondensation arising from chamber design and airflow control.

I wouldn't be surprised if in 20 years people look at our atomizers today and think of them as a primitive and archaic solution to a complex problem.

I do already. We need solid state micro dosing pumps to feed the juice! Regulated juice control.

Really interesting point about wasted heat!

Regarding the whole Chinese thing, most of you are posting or reading this on a PC in which the bulk of the parts were manufactured and assembled in a Chinese factory. Or using a tablet or phone which is also mostly Chinese-produced parts and labor. All connected to the internet with a Chinese made router or modem. The most important technological tools and entertainment devices in the world, and we trust the Chinese to make them for us.

The richest company in the world, with an enviable reputation for quality control is Apple, and it couldn't exist without China (and a little help from S. Korea). Same for Qualcomm, HP, Dell, Nvidia, AMD, and so on. Intel doesn't rely on China that heavily, but that's because they've found other cheaper second and third-world places to manufacture their chips. Almost all ARM-based processors are manufactured in China now.

Samsung is now (and has been) one of the world's most successful consumer electronics companies, LG is running neck and neck with them, but it wasn't that long ago when S. Korea was synonymous with cheap junk, be it electronics or cars. Just like Japan was 30-40 years ago, before the rise of Toyota, Honda, Sony, Panasonic, etc.

There's a lot of interest in it, not only from the e-cig side, but also for medical inhalers. Micro dosing pumps might work, but also one could use the bernoulli's principle and the venturi effect (akin to a carbureter), mechanical aerolizers, or even chemical processes to create an e-liquid/air mixture. Part of the problem will be figuring out what sort of e-liquid/air mixture works best for vaporization, which requires medical and other research. Miniaturization and reliability will be engineering issues to overcome. In addition, someone is going to have to figure out a high-speed atomization chamber that can vaporize the mixture at the right temperature, which is an ongoing problem in part because no one seems to have found the perfect heating source yet (i.e., quick, accurate, precise, and practical). The e-liquid too might need to change (nicotine has a high boiling point, which leads to recondensation), so we might be vaping an entirely different liquid one day.

If the industry continues to grow, I'm confident that the research and engineering work will be done to figure all these things out. However, it will also probably mean the end of vaping as a hobby (because everything will be too complicated or precisely controlled to allow for home experimentation), but the vape itself will probably be light years better than where we are today. I think I could live with that.

So you think the iPhone wouldn't exist without China? If China didn't produce it, you don't think Apple could find another vendor?

Most semiconductors are built outside of China. Or maybe I should say the designers chose the best chip, sensor, screen for the task. Those aren't frequently sourced from China for the high end gear. Assembled there, yes.

But, what is actually built there that's known for quality?

I have nothing against Asia. Sony is producing the best image sensors in the World. Actually, each country has their specialty, and seem to do them well. Samsung's screens. Taiwan and US semiconductors. Japan's optics and sensors, although Taiwan is also good with optics.

Not sure what that means, because I have a pile of sub-10 year old PC's sitting next to my desk. Mostly MOBO issues because I can fix everything else. Now, they're spare parts.

I was trying to push this idea years ago. Back when we were cutting little silicone circles to put in our cartos so we could eliminate the filler. I would've thought cotton or filler would be gone by now. But, temp control does undercut the need to eliminate it. The worst of it is the burnt hits. That may not be an issue anymore.

At some point I did find a deal breaker. Quantity. It's hard to deliver a lot of juice with a small pump like that. In truth, the amount doesn't have to be so precise, but it has to be enough. A venturi, is another idea I had, but never went anywhere with it.

I'd actually be all for eliminating most or all of the PG and VG, but just delivering the flavor and nic. Not sure what the experience would be like.

The contractors, Siemens and ThyssenKrupp were not Chinese companies. They built the Meglev.

The Chinese contractors built the track. My guess, the limited technology transfer was a way to prevent the Chinese from stealing the technology.

But, we're not talking about where something was designed, we're talking about where it was built.

I'm not immediately disregarding your point that there isn't a product the Chinese couldn't build better. I'm just pressing my brain to figure out a single example.

EDIT: BTW I posted in this thread to be TALKED INTO buying the SX Mini M-class. With e-cigs, good enough quality is good enough for me.

I was just going by the published data (pretty clearly stated by the previous post) where it said "first four car train built in China)....I wasn't there so I don't personally know.

Yes! As with cars. I remember my teenage days with a wrench in my hand trying to get a little more oomph out of a flat head Ford. I don't think that sort of thing is as popular as it used to be for the average kid.

The link you posted is from a thread discussing whether the Maglev was the German built one or whether the Chinese had copied it. My read between the lines, is that Germany builds the cars and China outfits them. Kind of like custom planes or busses.

But, it seems that China did borrow, copy, steal the technology.

My reading is that China paid the Germans to use some core technology and built the cars in China as reported in the literature using some components made in Germany.

This whole argument about Chinese manufacturing quality is not really relevant to the forum here. First, China is a huge country with a huge manufacturing base. A more proper comparison might be more with an entire continent. For example, Europe is known for making great cars and terrible cars, but everyone knows that car quality comes down to what brand you buy. Even more proper is to look at the e-cig industry as a whole and in terms of brands. Evolv, for example, has had terrible quality problems with the DNA40 at much expense to their customers. YiHi meanwhile has an excellent reputation in the industry for reliability, performance, and addressing any quality issues. Sure, the paint was defective on an initial batch one one type of model, but YiHi caught the issue and is replacing them with a brand new device. That's a lot better than what GM or Ford do when the paint goes bad on a car, which is an ongoing issue in the automotive industry.

Oh, and let's not forget where American industry got its start while we are at it.

Not really conclusive, but...

Civil Engineering « NAMTI

While construction in Shanghai progressed, ThyssenKrupp was transforming what had only been a prototype TR-08 maglev vehicle construction facility in Kassel, Germany into a full-fledged manufacturing plant. The SMTDC ordered 15 vehicles to constitute three 5-vehicle consists. Once the Kassel plant was fully converted to mass production, it produced one vehicle per month. The completed vehicles were then shipped to a facility constructed at the end of the Shanghai maintenance spur for final assembly. In addition to the maglev vehicles and guideway stator packs, ThyssenKrupp designed, fabricated, and shipped the eight bendable steel guideway switches for the system and supervised their installation.

Excellent points and to my mind exactly right. One can find good and bad everywhere and labeling Chinese=bad/American=good is irrelevant to fact. I live in the USA and I let my flag wave by the front door.

And yes, you are right. I have an interest in building timepieces as a hobby...we got our big push in the industrial revolution by taking Swiss designs for watches and building them cheaper. It's sort of a normal way that a technologically backward country becomes a technologically advanced country right?

Didn't make us bad then and doesn't make China bad now. It's the development path of the worlds societies and knocking it doesn't make much sense (at least to me).
