BTW (sorry a bit offtopic):
Did again quite some tests last night, and just have to say, I cannot anymore be high all the time, just for testing...
What would you think could be a good substance for tests (non psychoactive), for not wasting any precious material? It should also be pretty temp sensitive, in that it starts to burn easily, when too much heat is applied and should also already vape at lower temps. So basically with similar properties.
What I again discovered last night is really, that blowing instead of sucking drastically improves vapor production.
(Attention boring Text Wall coming...)
BTW: Did last night tests with the G9 enail dab rig, the QQ, the motar and the MBT.
And as strange as it seems, in the end, I still found the MBT to be the best one (if you blow into it), if your goal is not to burn any substance at all. The QQ is just not really usable for TC. I always burn substance, no matter what. The MBT seems to be the most evenly tempered one,but unfortunately still far from good IMHO. That's why IMHO it needs an atomizer design, where such different temp zones cannot exist (which is why I came up with the tube and foil atomizer ideas)
The motar lacks any TC and is heightened where the coil is, which is totally impractical for small amounts of substances. But other than that I found it actually pretty decent.If they would correct these points it could be a blast (except that it is making an annoying whistling sound, when you draw...)
What I discovered with all of them is, that quite some material condenses on the "cup" walls and wont evaporate anymore from there. Also with all of them the middle is the hottest, so that there it quickly evaps, but then not much anymore as a lot of substance creeps/condenses to the walls and the middle remains dry. So then you have to increase temp, that it also evaps there, but this leads unavoidable to some burnt material.
If you, like with a dab rig, constantly move a pin around in it, smearing the stuff from the corners/walls into the middle, where it is hot and no substance anymore, it works pretty good. But that is a tedious process and should not be needed. E.g. one could theoretically have some electronic means for this (e.g. like in an ice machine). I also tried adding some small metals balls into the cups and wiggling the cup while inhaling to improve this smearing. And yes, it improved a bit, but not worth it.
I could imagine adding a small metal bar and controlling it magnetically from outside so that it rotates constantly could work, but quite an effort...
Especially on the enail this was very extreme,as the central nail is very hot, but the cup around where your substance melts into is way way cooler. But I already asked in another thread about this problem.
So my conclusions are: I will definitely try to make the e-foil atomizer. But from SS316 not titanium. Simply because much cheaper, and SS has more resistance, so the device need no to be overly large. I will probably make two foil surfaces about 1-2mm apart, as mentioned before with either glass fiber paper or ceramic paper on the surfaces. Also planned with some simple heat exchange between incoming and outgoing air. And I try what difference it makes,if I would incorporate a pump to blow, instead of sucking. E.g. I could even imagine it could be beneficial to have many small holes in the foils and their mounting plates, so that the air comes in everywhere. This should help in not getting high temp differences, which would be unavoidable if you make one long part where the air gets it at one side and out the other.
The TC will always control the mean temp of your "coil"! (if one area of the coil is colder, then another area is hotter)
BTW: Another idea would be to heat the substance as liquid to a good evap temp (e.g. going through a small heater tube), where it will not yet burn and then spray it into fine droplets, which should then immediately evap. The second part is e.g. used in some oil nebulizers for aroma oil, where a small air pump disperses the liquid.
Oh boy...me and my stupid ideas...
