Can any one simplify the YiHi joules temp control

[Marc411]

Well at least they are talking about it, we didn't get much information on the dna until it was released. Very hush...hush

That being said I guess we'll all find out in a week or so like we did with the dna chip.

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?

According to a post from a guy who has actually held one of the units, it is using nickel for TP just like the dna-40. This means the joules have nothing to do with it. So, it appears they are just using the exact same technique as Evolv.

 

[BigEgo]

This is why I asked if It is Total Joules per Hit. Or if it is Joules per Second. (Which is Kinda Redundant because the Unit of a Joule is per second.)

I believe they are saying the Range is from 5 Joules/sec to 50 Joules/sec.

And doesn't that Jive with a 5W ~ 50W type board?

Joules per second = Watt. That's the definition of a Watt, so it makes no sense to say joules/sec. A joule is a unit of work, a watt is a unit of power. A joule is a joule and a watt is how many joules per second.

Good assumption imo....joules just replacing the wattage setting... ex. set to xx joules as opposed to xx watts...my search for info thus far is sparse... maybe Yihi will answer my correspondence....Yihi says release middle March...one vendor doing pre-order says middle to late March for the mini M...

At least you guys now know what I felt working with fahrenheit.
I guess YIHI thought "why only screw Europeans if we can screw everybody?"

Yep.

I though about this "Joules Mode" concept last night. And I kept asking myself why Express a Value in a Time Dependent Unit.

The Only thing that came to mind is perhaps they want to Express Work over 1 Second where the Watts vary.

Take the Graph below...

I know. It Isn't probably the Best Graph to use. But it was Easy to Grab so I did.

If 1 Second is Defined on this Graph as the Horizontal Distance from the Vertical Axis to where the Shaded Red portion intersects the Horizontal Axis on the right, what would be the "Wattage" for this 1 Second Interval? Verses, what would be the "Joules"?

I very confused by this Entire "Joules Mode" thing. And am wondering if it is a Way of Limiting the Peak of a Non-Linear Wattage Graph when doing Averaging?

That, or I need more Coffee.

to all I started the thread for the reason of finding out what the joules measurement meant and how it was useful info in the SX mini M class mod. The point of the thread is for my self and other less informed members to understand what joules are and how they can be applied to vaping.

I can see the twist and turn and side conversations about NR wire but your opinions about the DNA and or clones good or bad dont really belong here and just junk up any information others might want to gain from this thread.
Thank you for being respectful to me and others who do not want to read these comments when they learn about Joules.

Basically it's how hard your battery has to "push" in order to give you the wattage you need to vape. Take note of the number, with a brand new battery the number will be high, and as it wears down it will decrease. Basically shows the wear and tear of your battery over time.

Not really. To me that Joules indicator will show the wear and tear of your battery over time. As it wears down, the joules delivered will be less and less.

I have an SX Mini and one thing I've noticed is that if I use two identical batteries that are of different age (charge cycles) the newer one will deliver more joules before it hits low power cut-off.

My take is that joules are monitored vs resistance beings monitored in the Evolv chip. Both based on achieving the watts selected. As an atomizer's resistance changes with temp increases, the joules required also changes. Coil temperature would be calculated form the joules change vs it being calculated from the resistance change used by Evolv. Using nI200, of course.

That would be smart... Instead of monitoring resistance change, they monitor the joules which basically relate directly to the resistance and necessary power... Hum... That's interesting... Maybe deep down they're smarter than we think. The temp in fahrenheit or Celsius would be then a mere representation of what they think relates to the amount of joules needed to heat a coil to a certain temperature... Ok. My brain froze lol.

No that would not be smart imo.
First of all one cannot "monitor" joules, it is a calculated unit 1 joule = 1 watt for 1 second.
yihi will have to monitor resistance change because it is the only thing changing that can be detected via coil "monitoring".

 

[tchavei]

Are you sure?

I have this temp limited mod, I fire it for 5 seconds, during that five seconds the watts will vary considerable.
Knowing that J=W/S how many joules did I create?
How does that relate to coil temp in any way?

What if the board is showing live current joule/s output instead of displaying joules over the total time one takes a draw?

at about 11 min in the video he talks about the Joules portion of the meter but it looks like Im wrong about the this being the heat sensing measurment its just part of the YiHI board because this review is for the way outdated S class its already a few months old!

Still not much info out there on the J chipset.... Still pondering how joules plays a part.... posting the following thoughts just as an OBSERVATION ONLY...

At 12:30 minutes in the video shown above it talks about the 3 modes..... Soft, Standard, and Power Mode.... and at the 11 minute mark it talks about joules... This is the video of the SX mini.(no TC)... Yihi boards are known for their ability to be usb updated so I ponder why a new chipset is needed to use joules to do Temp Control? They say they are doing TC with joules with this new J chipset.. Why is the firmware not just updated?

My request of Yihi for information was partially answered.... The warranty questions were addressed but none of the questions about joules (temp control). I am gonna guess that this J chipset will be doing a similar function and process as other (evolv) TC chipsets and will await a valid explanation as to how joules is used in TC...

Noted that Yihi uses the same Soft/Standard/Power Mode graph (shown above) for the SX mini and the soon to be released J chipset....

 

[Woofer]

Why is the firmware not just updated?

Why not indeed, that is the 200 dollar question.

What if the board is showing live current joule/s output instead of displaying joules over the total time one takes a draw?

I don't see how that changes anything, joules is over time by definition.

How many KPH can I go in zero time, how long does it take a photon (traveling at the speed of light) to arrive at it's destination?

What does the board know about the coil?
It kind of knows the coil resistance, stable connections at all that jazz and it knows the temp/resistance coefficient for Ni.
That is about all it knows.

Put another way if you tell me the base resistance and temperature and the end resistance I can calculate the end temp
If you tell me the base resistance and temperature and the number of joules I can not tell you what the end temp is.
yihi can display whatever they please I maintain they will have to use resistance monitoring to arrive at something to display.

If I were yihi and even if it was possible, why should I upgrade boards if I can sell new ones with temp control?

That's the same as saying why does Evolv insist of making non upgradable boards? Obviously to sell more. There isn't much profit in upgrading unless it's to fix bugs.

I don't understand why even asking or implying something about that... That's economics 101...?

Everything is made with a certain time frame in mind and then we move to the next great thing.

Evolv replaces problem boards under warranty. Evolv boards are not intended to be reprogrammed. Evolv has NEVER done anything via firmware for the purpose of selling more boards to people who already own the board.
