    YiHi announced this chip on their Facebook site. No specific details at this time. Since the SX Mini displays joules, hoping they release temp control with an update.

    I have my fingers crossed that Yihi gives SX Mini owners joule control updated firmware.

    Definitely excited about this (and Imeo's VIR). Hopefully they'll post an update with stats soon. Just whetting appetites does no good.

    Unless it keeps you away from the DNA40, then it does. Classic vaporware scenario for future computer software releases (not saying they won't do it...).

    My trigger finger was getting itchy for a yihi-powered box. Maybe I'll just wait a few months to see what shows up.

    we have to wait :-( but its great - hope Pioneer4You will do something with this... The rDNA MOD is hard to get in germany... So Yihi makes that we have more temp control box mods :) yeeeeeaaaah

    Well yeah. regulation in europe is about to kick the vaping scene here in the face soon. also it's expensive for european vendors to get box mods from the US because shipping is huge and our customs tax the .... out of imported stuff so the profits are super low. also 200 euro+ devices don't sell as much as 50-100 euro devices so stores are not that willing to stock those devices and when they DO they get sold out immediately meaning these things are always sold out and they maybe come in stock like once a month ish?

    plus everybody here seems to ....ing love the hana for some reason.

    Do you guys think that this unit will require nickel wire like the DNA 40? Also, what the heck are joules and why should I care?

    A joule is a Watt-second. It is a measure of power over time.

    Basically, one joule is passing an electric current of one amp through a resistance of one ohm for one second.

    It's a better measure of energy output than just saying watts.

    Very much looking forward to this new board. If their track record is anything to go on... i think this could be a game changer if they figure it out and it operates better than the DNA 40. 120 watt... 200-580°F... down to 0.08 ohm... output up to 9.5 volts... that's big.

    This is why I have trouble understanding what this has got to do with temperature control. It can be argued that any VW mod with a 10 second cutoff has joule control.

    I'm not saying that this thing doesn't though. I just don't get what they mean by it.

    Are you good with science? Meaning, hard science?

    If so, you'll undestand it better. If not, it is a LOT of learning.

    Basically, heat is measured in joules. In the UK, heat is measured in BTUs. Imagine they're the same thing. Heat is NOT temperature. Heat is what raises the temperature of something: imagine a liter of water at 100 degrees. Heat is what raises the temperature of that liter of water from 100 degrees to 101 degrees.

    Joules is the measurement of that heat.

    If you know how much heat you are applying to something (joules of heat), you can know what the temperature of that something is. Applying heat to a specific metal (joules into a specific metal) should give you an ability to estimate what the temperature of that specific metal will be.

    This is me trying to put it in simple terms. Sadly, the science is tricky enough that it isn't so easy to describe it simply.

    Would external variables change the amount of heat needed to bring something to a desired temperature? For instance could air or liquid moving over metal change the amount of heat needed to bring the metal to a desired temperature?

    Except there are many variables that change massively, airflow, liquid feed rate, liquid phase change, etc., which affect what the actual temperature is. That's kind of the point of temp control.

    Agree. Also why "variable joule" is a joke.

    Variable temperature, fine. Variable heat? BS.

    I understand the difference between heat and temperature. What I don't understand is what exactly this board is doing differently from a VW board.

    If someone can explain that in clear, scientific and precise terms (by all means, do use electrical engineering jargon if needed, and/or equations if that helps), that'd be great. :)

    Well it seems to imply an automatic time limit. So it will cut out once it hits the joule number you set.
