sure, that thread is ridiculously long - it covers 9 years of iterating. here is the diagram of air flow: there are three pieces of glass: the oven tube, the vial that holds the herb, and the draw tube. the heater ribbon is outside the oven tube. air is isolated from the heater - which...

don't want to sidetrack the conversation but need to correct this … the air comes in through the top of the cube, then up through the vial, and out the top of the vial into the draw tube. 100% all glass vapor path. 100% isolated from anything but glass and herb. there are diagrams in my...

it's July/August, so … watermelon!!! the perfect sports drink after my morning workout. otherwise only well water or coffee.

forgot to answer this … i find 400F to be sufficient to get good vapor. the pcb is on the side opposite the heater and below the heater - so components are not noticeably affected by the heater, except the temp drifts up about 5F toward the end of the 7.5 minute session.

i had a cylinder design several iterations ago, and it is easy to hold, too. i have an all glass airpath also: borosilicate flat bottom vial holds the herb, that fits into an oven tube that is heated on the outside with a nichrome ribbon heater, so ambient air travels between the inside of the...

i meant my cube is easy to hold in my hand … and my pid controller and a k-type thermocouple, are in the cube - two buttons for temp setting.

yes, and after the first 5 or 6 hits i need to stir and break up the pieces, which are quite crispy at this point … the cube is easy to hand hold.

the purpose of the decarb is to convert the THC acid molecules into THC delta9 molecules, which is the bioactive form, while THC acid is not. the terps are vaporized at a fairly low temperature, so they are wasted during the decarb. the NOVA is doing about 110C (maybe 105C?, there is a chart...

@Mookie0608 - i use the Ardent/NOVA for decarboxylating - it contains the smell very well and has been tested to do virtually 100% decarb of THCa to THC ... however, some FCers have had negative experiences. i like mine. thread: http://fuckcombustion.com/threads/100-decarb-with-the-nova.20534/...

i think to get the vap cap to click in a reasonably short time, it would take about 1000°F - far too hot for the cube, i'm afraid. plus, it shuts down if it goes > 500°F. the induction heater is a better tool.

first of all, thank-you for your continued interest in my vape. if i can get it ready for mass production - well, that's me and my workshop - it will just be available for purchase. no preorders or deposits - just buy it and get it. but still quite a few steps between here and there. and...

@felon167inc - thanks for asking … i have finally finished some work and household projects that have been nagging at me for about a year - plus pop-up projects like replacing the wax gasket under the toilet in the mens room, because for sure the world stops until both commodes are back in...

@ClearBlueLou - i got a NOVA almost 2 years ago - used it a bit, then April a year ago ran about 12 oz thru it to make RSO for gf who was dealing with melanoma - evidently that was successful. And two nights ago i watched a video of Shanel explaining decarboxylation and it dawned on me that...

to get a "properly" performing vape takes about 50 watts … that would be a LOT of hand pumping. to answer your first question, yes i have designed and built my own vape. i went the: all glass vapor path, computer controlled heater, digital temp display, battery powered, and with a carrying...

with only a quick read-through, it seems the 446°F is optimal for a single bag extraction. That is, more cannabinoids will be extracted at once at such a high temp. But, at lower temps the cannabinoids didn't disappear, they are still in the sample and can fill another one or two bags. I...

i made this calculation for my Bud Toaster vape back in 2015 when the topic first came up ... Surface area of the heater tube exposed to the air flow = 1552 mm^2 Volume of air being heated = 842 mm^3 So, Surface Area to Volume is 1.84 ... i can't remember: did RBT ever state his ratio? i know...

that fucking cracks me up ... but, then again, i am high. bump.

also, a volume increase cools the vapor nicely ... such as, going from the 11 mm vial in the heater into a 18mm dia x 150mm long stem, which is a noticeable improvement over a 14mm dia x 100mm stem, so maybe wider rather than longer. it is also very satisfying to see the bigger tube fill up...

there are threaded vials and test tubes that take a plastic cap - only a couple dollars each - so a threaded collar could couple two pieces together. but, if it gets knocked over it will most likely break the glass ... i had one knock-over-glass-break 10 years ago and my design ever since has...

well, i was going to dish some dislike for the original PAX, but, as the vapor settled in just now, i realize it is the girl friend (it was her vape - my BT is too fiddly for her usage habits, and as even god knows, she has no need to change) (and i say was, because after a while she gave up on...
