Can any one simplify the YiHi joules temp control

[zoiDman]

The thing is we don't measure heat directly.
We measure heat by noting material behaviour in its presence.
A T coupler monitors voltage change, a resistive temperature sensor looks for resistance change. (What Evolv is now doing)
A bi metal strip or analog thermometer rely on movement.
I am told IR is not a good method for coil temps.

What could this direct temp measurement be and how would one do it.
Using the coil as both the heat source and temperature sensor is brilliant engineering and it is as direct as can be.

If I do the Math and tell you What Temperature a Piece of Nickel Alloy Wire should be for a Given Resistance and Volts, does this take into account the Size of the Air Hole on the Side of your Favorite rta?

Or if you are using a Huge Strand of Cotton? Verses a Very Small Diameter of Silica?

A Direct Measurement of a coils Temperature Doesn't Know or Care what your Setup is. It just tells the Circuit Board How Hot the Coil is at a Given Time.

Greek to me..... I only see Pretty colors....if you see red.green, black, with blue writing it means you aren't color blind...lol

 

[Woofer]

bust out your O-Scope FLIR and dummy loads and show us how he is wrong then

I don't remember the FLIR or load testing showing much other then being 0.5 volts short of the 9 volt max spec.
Anything I have read about it says FLIR is a terrible way to measure coil temps.
I assumed with all his test gear and experience he could wind a coil and find and eliminate weak connections.
I was wrong, he is two thumbs and a mouth.

Thankfully most reviewers have a different opinion on the dna 40.

Yes, that is exactly what sensors do is do the math.
The size of the air hole, the size of the wick, the wire size etc. do not change the temperature coefficient of resistance for Ni wire.

The DNA makes one small assumption that is common knowledge at this point.
It assumes the mod and the atomizer are the same temperature while establishing the base coil resistance.
From that point on it accurately and directly measures the average coil temperature.

I believe that is an acceptable assumption given that this method means all existing attys potentially are usable with TL.

You seem to have left out the way nickel resistivity variation with temperature is being used to measure temperature in dna40 mod.

I think where I see the Benefit of Direct Measurement is it would Allow for the Use of Any Type of Coil Material. And Not be Limited it to a Nickel Alloy.

No. The Consideration of Nickel Alloy is Actually what is Driving my Chain of thought.

What happens if a Person Doesn't use a Nickel Alloy coil on their DNA Temp Control Board? Does it Still do what it is Supposed to do?

 

[Susaz]

Think basically this:

Car stranded, you have to push it to make it work and that work generates electricity. Joules would be the mesure of how much you had to push to convert that into electricity. Hope it's less confusing that way.

 

[retird]

Asked google: How do you convert Joules to degrees Celsius?

Answer: There is no conversion. These units are not compatible. For water only multiply by 4.184 since 1 calorie = 4.184 joules, and 1 calorie is the amount of heat needed to raise 1gram of water 1 degree Celsius.

temp control chip SX350J

It over/correct/under volts for the first second of firing. Less ramp up time in Power mode, more ramp up time in Soft mode. All this works with Kanthal already on the SX350. I would assume you still get that option with Ni200 on the SX350J.

Keep in mind Evolv does something similar to Power Mode with their "preheat" mode on nickel builds, but it's not optional, and it it's not configurable, and it's not available on Kanthal.

I can go for that....but the SX350J is said to do Temperature control....with joules....nobody can give a straight answer... can ya shed some light?

Gotcha.

The More I hear about this Chipset the More I am curious what people who are Using it think.

How long has the SX350J been out?

 

[SavePaperVapor]

I have a feeling this will be about as accurate as the DNA chip. In fact, I'm pretty sure it will be doing the exact same thing but have a different readout. For all the variables involved the evolv chip does a solid job. With it, I've had the best vaping experience of my life thus far. Hopefully the ipv4 I preordered will give me a similar experience.

No, the dna40 temp control is calibrated for Ni200; if you use Titanium as some people posting on this forum do, it works, but the numbers are just different because the dna40 is calibrated for Ni200; if you use kanthal, you use regular mode not temperature control mode; the resistance variation of kanthal is not high enough to use for temp measurement at the moment.

SX Mini M is supposed to ship to vendors on the 20th. Outside of Yihi no one has one in their possession unless they're bound by an NDA because nothing's leaked yet.

i don't know how soon the chip will be available. I imagine they're throwing everything at satisfying initial demand for the mod first.

 

[Croak]

I think there's a mountain over there, which is everyone's speculation. It used to be a molehill.

Seriously, does anyone think Yihi, which has a track record for at least a decent user interface and understandable features will release something as arcane as a lot of you are trying to make it out to be?

For temp protection, you'll use a nickel coil. You'll set your temperature. You'll select power. You'll vape. It'll limit power once it hits temp. It will have an (optional?) display and control parameter, joules, which might do nothing more than give you a better idea of battery economy.

Like Croak said.... a lot of speculation....From Yihi's web site:

We are glad to share this chip with you. Stock available in the middle of March

I've found no reviews, no videos, and no vendor stocking them.... and no information about the temperature control feature other than the spec sheet info.. that should change when they hit the market.... and am hopeful that Yihi will reply to my request for information...

I think my issue may be with your use of direct measurement.
It is not possible (ever) to take a more direct measurement then using the actual coil.
Any additional sensor will use a similar strategy to arrive at the temperature, voltage change, resistance change, size/position change etc.
External sensors bring no magic to the party, they are hamstrung by the same physics as Evolv's temp sensor.

Lets say that we had an atty/mod combo that used an additional sensor to determine coil temperature.
If this sensor is not touching the coil it is not measuring the coil temp it is measuring the air temp at the sensor.
Now things like airflow levels are a huge problem.

No. The Consideration of Nickel Alloy is Actually what is Driving my Chain of thought.

What happens if a Person Doesn't use a Nickel Alloy coil on their DNA Temp Control Board? Does it Still do what it is Supposed to do?

The board is a top performing power supply regardless of the coil material.
It does what it is speced to do.
For the foreseeable future all TL mods will require Ni or possible Ti coils.
Alloys don't hold much promise and we are fresh out of new stable elements.

Its a Cadillac it has some features most will not ever use, but the regulation is done well and the mod quality is up there with the best of them Im buying it if for no other reason than to finally have something quality from China in my collection. When I saw it had Joules on it I think its cool to learn something new its cool an interest of mine vaping has turned out to be such a learning experience.

I had zip zero knowledge of IMR batteries very little about DC power period other than DC is direct and AC is alternate Now I have a mulit meter oscilloscope I made a Hammond DNA box if soldering with a magnifying glass with one eye shut to is not skill I dont know what is ;-)

as vaping evolves so dose the hardware and if you try to keep up and understand what your uesing so dose your knowledge.

just a thought if a device was prosperity and had lets say a built in Kayfun type atomizer could it not have a temp reader kind of like whats in a multimeter?

So you have one and can fill us in on all the questions asked in this thread? ?? I'm interested in what ya have to say...
