New studies find carcinogens in vg and pg at high temps, even in tootle puffers

[mikepetro]

OK, so looking at that image full size:
(hopefully you won't mind that I stole it and cropped it)

It looks like about
10-11 seconds on
~15 seconds off
11 or 12 seconds on,
~23 seconds off
~17 seconds on.

The last one is like:

4-5 seconds is a long hit for me.

No way...
Remember that the peak would be when I let go.

In looking at it close, the Escribe graph gives a better picture, I think it scans every 1/10th of a sec..
I didnt capture the first puff in this snap,
The second puff was about 3 sec
The last puff was 7 secs

OK, I was thinking each line segment was drawn between 1-second samples. But if it's one minute from 0 on the X-axis to the dashed vertical line, that can't be right. I don't suppose you kept the raw data in a .CSV or something?

No, sure didnt. Could have, the software is capable, wasnt concerned with it at the time.

 

[Rossum]

Yep, drippers and squonkers should be a heck of a lot easier than these tanks.

Something like this is well within my budget....

Looks decent, do you know what the fastest sample rate is? Thats the most limiting thing with the Solo software, 1 sec scans are actually pretty slow for this application.

When picking a thermocouple, the smaller the better, faster response time. I used 30awg last time, will be using 36awg tomorrow, the 40awg intimidates me.

It says: "250 ms Conversion Time", so I'm thinking 4 samples per second?

I was gonna ask if you'd be willing to share your sources?

Yeah, wasnt quite sure what "conversion time" meant, but if that is the same as sample rate it is better than the AutomationDirect Solo stuff.

I got my thermocouples here:
Insulated Thermocouples

These might be better as they already have the connector on them, otherwise you have to buy connectors too. Assembly is no big deal.

Gave it a go with some 50/50 juice. Looks like I am going to need to make some high VG juice for this thing.

I am cranking it all the way up to 28w and it still acts like it is flooded, lots of gurgling etc. The anemic vape I am getting is hot, not burnt, but hot to the throat, yet it only measures 300-400f. If I take the tank off it looks flooded. With the tank off after I fire 3-4 times it starts looking normal.

Anyway, what I am getting now would not be a satisfactory vape to anyone, so its not worth methodically testing. A little later I will mix some vg juice and see what I get.

still acts like it is flooded, lots of gurgling etc.

That's strange. From the looks of the way you are doing it, it should not affect wicking to the coil, IE if 50/50 worked before, it should work now.

Sounds like a vacuum seal problem?

I don t know that it work before. It was a brand new coil, and I dont vape these so I dont have a feel for them. My GF vapes the 1.2ohm coils.

Anyway, I made some Vg juice with 3.6% nic and 3% DW. I let another new cartridge soak for about an hour, going to string the thermocouple in there now.

 

[mikepetro]

Well, it looks like I had two problems.

The first cartridge was packed much much looser with cotton than the second. What I was doing was sticking a sewing needle through the cotton next to the coil to make a "hole" to stick the thermocouple in. I could tell a huge difference in this second coil, the cotton was much more dense. That explains the flooding on the first one.

The second problem is that I am not getting good contact with the coil. I was getting temps I didnt believe. Like in the low 200s on a decent hit at 20w. So I started jiggling the thermoucple and the temps jumped up.

So now I am playing with it to figure out good contact that will stay in place through several hits.

 

[mikepetro]

It was tricky, but I figured out a way to snake the thermocoubple in through the bottom and up through the center of the coil. I made a wide radius 90 bend at the end of the sensor so it bends over and keeps contact with the coil, like a spring. If the tension stays there this will be an even more robust setup than my first attempt. A few test fires gave me believable temps. Letting the coil prime well now as I started with another new one. The cotton starts swelling with juice, and that prevent me from snaking the sensor up through the bottom of the cartidge, the sensor is pointy like a needle and kept getting stuck in fiber loops of the cotton. Anyway, that why I couldnt start with a saturated coil.

So, which view would you rather see? The top view is much easier for me to do as its a simple copy paste into ECF. The bottom one I have to do screen capture, save it, then u/l it to photobucket as ECF wont let me paste that large of an image.

This is at 13w btw:

 

[mikepetro]

10w

The easier for you seems fine.

 

[mikepetro]

11w

 

[mikepetro]

12w, curious it is hotter than my earlier 13w sample, perhaps because the mod is warm now?
