Temperature is the measurement of the average amount of heat present, not the total.
Heat is the amount of energy transferred.
seeing how the same amount of energy, applied to different coil mass, will create different amounts of heat...ergo different temperature. But the temperature lets you know how much heat is present, not how much energy, therefore temp = heat.
No, the amount of heat energy transferred will be the same regardless of the coil mass. It's just the larger the coil mass, the lower the average amount of heat. Or in other words, the lower the temperature change.
50J is 50J. If you apply 50J the heat transfer is the same no matter if you are heating a 32 gauge 1.5 ohm coil or a 22 gauge .1 ohm coil. However, there will be a difference in the average heat (temperature) between the two even though the same amount of work (Joule) is being done to transfer the same amount of heat in both cases. 50J in a cup of water and 50J in the ocean results in the same amount of heat transfer. The difference is that it wont raise the temperature of the ocean but will raise the temp of a cup of water.
Someone asked how we even got on this topic. I had to go back and look as I didn't remember. It had to do with "Orivape" asking the following question:
He is suggesting here that 40w is 40w (and generates the same temperature) no matter the build. It is perfectly feasible to vape at 200w (for example) and generatre the same temperature that 40w on thinner wire would generate. In fact, this hits at the heart of the matter and actually proves that what I am saying is a fact: the total amount of heat transfer is not proportional to the increase in temperature.
An easy way to think about this is to think about a coil the size of a telephone pole. Do you think 40w would result in as high a temperature change in that coil as it would to a 1.5 ohm 30 guage coil with 6 wraps?
Brandon from Evolv talked about this in one of Phil's videos, but didn't elaborate or get technical. He said something like "heat and temperature are not the same. It's complicated but all you need to remember is that a higher temp does not mean more vapor." He is right. You can produce more vapor (because of higher watts, which means a higher heat transfer) and still maintain a vapable temp (say below 500F) if you build correctly.
Well I went and did order fresh spools of fine constantan and fine iron wire. Yes, we are going to place a thermocouple at each wrap of a spaced coil in a functioning atomizer. It will measure temperature, or heat, no temperature lol.
I'm interested to see the interplay of dna's method of limiting average temp of the wire with spot temps at each coil wrap interval along the wick. The jumping off point to try to optimize coil design to keep the spot temps within some % of average temp is next. This will be fun.
Oh and if temperature is average heat, then what is average temperature? lol. (That was a joke; don't bury me with replies). Heat is work or energy, etc. Temperature is a measure of that work or energy, etc. This ain't rocket science lol.
Edit: added a spool of chromel to the order. Let's try some type E -- supposedly more accurate (and higher dVdT)

I saw (or didn't see) their DNA200 announcement pic was taken down or hidden (or I couldn't find it) but I saw a post that said the DNA200 would be out before the end of summer
I could still find it. They also said their board will be different than others, not sure what that means.I saw (or didn't see) their DNA200 announcement pic was taken down or hidden (or I couldn't find it) but I saw a post that said the DNA200 would be out before the end of summer
Ah the old "Bait and Switch" routine. Put out a few beta boards that do what they should and then when the production run comes out it will be physically different. Clone - Oops got-cha!!!
Anyone who has been building (correctly) for long enough will understand that. But for our purpose the average amount of heat (temp) is what matters. Is not temperature the measurement of heat in a closed system? Is not an attomizer a closed system? It's the temp of the output that matters. I.e. Empirical temperature vs. Joules. Sure there are many ways to arrive at the same average, using different amounts of energy, people who build understand this without even knowing they understand it
.So basically, you are talking about joules in the coil, and I am talking about the temperature in the vapor.
haha, but if we dont get butthurt, you have to admit there is much truth in those first 4 minutes
Can we stop arguing about temperature, energy, heat, button number, menus, LiPo love, LiPo hate, YiHi vs. Evolv, etc and just get some good old info and banter going about the topic this thread was originally intended to be about? No? Oh, alright. Carry on. I guess it was too much to ask that a long thread doesn't get completely and irrevocably derailed.
A dude told me yesterday they 200W TC boards were released in the UK on the 25th in "a few outlets," whatever that might mean. I haven't seen anywhere around here where you can walk in, lay down cash, and leave with the board. Or even place a firm order online. There's nothing on Evolv's website and verybody else is still taking "preorders."
I'm not butthurt and I don't even remember most of the 4 mins I wasted on that video. I just don't like anyone lying about a product they have very little understanding of. This goes for other brands too, not just Evolv.haha, but if we dont get butthurt, you have to admit there is much truth in those first 4 minutes
I don't consider myself a fanboy of any brand. Sure, I have brands that I like more than others but I don't follow/support them blindly. I'm a huge fan of Evolv and their DNA40 for various reasons (product, support, service, design). I recently bought a couple of SX350j mods to try out because curiosity finally got the better of me. The first was the SX Mini M Class. Meh. It's heavy and still has sharp edges and my hands cramped and had sore spots (particularly on my pinky) after less than an hour of vaping and I wasn't holding it the whole time. That's the main reason it's for sale (still!!!). So if it's so great, why isn't it selling? I did like the chip enough to get a Boxer with dual batteries. I've used it almost exclusively for the past week and after the newness wore off, I find myself going back to my 8 month old rDNA40 or 1 month old DNA40. And both function perfectly and vape the same even if they're different versions of the board.
Bottom line is the bugs in the SX350j affect vape quality, the bugs in the DNA40 doesn't.
There's two online vendors we know of already selling them in the UK. I ordered mine Saturday, so I expect it to ship tomorrow and be in my hands Tuesday morning.

I can't imagine it would be in any B+Ms.. unless they're very specialist ones! Most of the B+Ms I've been in barely know what an RDA is, let alone a DIY board
I expect 'outlets' refers to online stores like the above.
Well, I understand why you want to eliminate the "what is energy?" argument, but the other things you say should stop could very well be on topic with this thread.
Just because a post isn't listing off things about the DNA200 specifically, and talking about another company, battery tech, different contact resistances of atomizers and 510 connections...and so on...doesn't mean this thread has been derailed.
If anything, you and I have derailed the thread.
The last post by KTM was a disclaimer about a video, directly relevant to the topic.. I definitely won't worry about watching it now..even though the thumbnail preview was enough for me to come to that conclusion on my own.
Who's hungry? I'm thinking Thai..

Thanks. I think I'll wait, though. I'm definitely interested, but I want to see some reviews. I know a 200W TC board would be fun to play with-- seems unlikely I'd ever be anywhere near 200W-- and I know Evolv has a good rep. But no sense being first in line about it. Besides, I have various parts for three different electro-mechs I'm working on strewn about right now anyway.There's two online vendors we know of already selling them in the UK.

so cloud9 has the boards in stock apparently and I have been thinking of just making my own box.
I do have experience in sodering and such since I used to get electronics and mechanics in school plus I have a friend that is excellent at it.
I just....don't know what parts to buy. like I have no idea on what to buy. what box. what 510. wiring is no issue. what button and so on. Hell I am not even sure what brand of lifepo4 to get.

I heard they officially released the sale of the board 6/27 at 12a.
It's not like these are Xboxes and every Walmart or BestBuy is carrying them so it's highly unlikely you'll be able to walk in anywhere to pick one up. Protovapor does have them and are available now.
