@vezj420 you don't want to use stone age eGo or VV/VW technology on these lovelies! You need a temperature controlled mod that can run well at low wattage and with power to spare, preferably one that can set both a temp and a wattage ceiling, like the Joyetech evic mini. Those even have firmware updates and programmable temp coefficient curves. That will let you find a sweet spot at which you can just press the button and vape, not worry about burning the oil, not worry about blowing the coil. This, dahlink, is called technology, progress ! Wheee!
I just got my first 2.7 white ceramic. What a
beautiful object all around, Matt ! That mouthpiece is brilliant.
My mods are
KangXin VF mini 50-D 50 Watts. They apparently use a chip that's very similar to what's used on the Invader Mini. There is only one default (nickel type) curve built in. They get down to twenny six bux delivered, especially the pink one ;-) and they're well-made. You just use different offsets for different materials. When I vape nicotine type VG liquids with Titanium coils, a 320 Deg F Temp setting averages around 420 deg F at the coil.
Matt's 2.7 donut atty measures around 0.7 ohms cold and requires a very different offset from Titanium on this chip.
Setting the TC to 200 deg F and the Wattage ceiling to 10 watts I see hunting between 380 and 450 deg F, spending most time around 425, which is not a bad starting point, since most of the cannabinoids, terpenes etc boil off below 450. Many more settings to try.
That's measured with a thermocouple and a 6802 II meter, with the bead either caught under the donut, like
@OF was doing, or held against it.
If I set the Emissivity to 0.50 on my IRT12A InfraRed gun and read the white atty by placing it at the throat of the IR gun, I get values that are close to the thermocouple's.
Haven't popped its cherry with oil yet. As the donut darkens the Emissivity will probably change, but the gun is still a handy way to get a quick reading. When I tried setting the target Temp at 320 I was getting peaks over 700 deg F, and it was the IR gun that alerted me!
Has anyone tried putting a little pan on that donut to boil the oil and not have any stuff dribbling below ? You know, like maybe a little glass disk, or ?
