    Salutations everybody,

    Today may seem like an ordinary date on the calendar to most anyone else - but me - because that's marking the end of a 5-yr mission... « To boldly go... », there:


    But that was then and this is now:


    It seems i've lost the fresh perspective which would have allowed me to express the novelty but at least i can invite adventurous readers to a simple challenge; i always tried to keep replicability in mind, after all.

    ;)

    VaporGenie has made the most promising move with their present line of products but that's not the end, i even believe they've got a potential killer in their hands that's also sturdy, reliable and ex-smoker friendly on top of being quite affordable - especially for a DIY.

    Please consider replication followed by peer reviews, with IH mode in mind, eventually.

    By using VG's pipe as a "Prototyping Platform" i've managed to open a window which provides a view i can only wish to share. Yet i'd like it even better if i could read about it in words other than my own.

    The "17-Holes Metal Disc" could happen to pose a problem but i've evaluated its weight must range around 0.75 g if SS304. Possibly DynaVap's "CCD Screen" may work sufficiently well as a substitute.

    Go wonder. Fingers crossed!...

    Good day, have fun!! :peace:

    Salutations,

    When words keep failing try falling back to simpler schematics, pictures and/or even animated video. For example:

    [ www.youtube.com/watch?v=jXNWOub5_Uc&t=7940 ]
    YouTube: Pac-Man World 2 [22] 100% GameCube Longplay (2016-Dec-21) @ 2:12:20​

    This legacy sample of Ms. Pac-Man is about its accelerator button being pressed in order to build up some rotational cinetic momentum, before symbolic "wheels" (so to speak) mate solidly with the ground and transfer such kinetic potential in a way to actually move at greater speed than usually possible.

    A temporary "Thermal Bottle" does a similar trick by allowing some time-compressed experience where there hardy was any that satisfied before. Just expect some longer pre-heating delay, i figure.

    Good day, have fun!! :peace:

    Hi Egzo, can I assume you are calling you're mod hybrid cause it transfers heat both by conduction and convection?
    Does this mean less or no stirring?

    My VG didn't see a lot of use lately, but I'm happy to say I recommanded it a few years ago to some friends and they still use it! Although I'll consider to test your mod in order to see the difference, I'll keep you updated!

    Salutations PPN,

    Thank you passing by!! :cool:

    Actually conduction comes last as a delayed/degraded mix of captured and re-converted energy... Primary convection heat gets carried into the Flame-Catcher via hot H2O & CO2 exhaust gases while projecting intense radiative heat that also degrades in ways i can hardly explain myself. The trick solving this puzzle was to proceed with successive iterations until i could decide what to try next, e.g. by trial & error until a "Sweet-Spot" configuration was found. It's all based on subjective criterias at each new step, compounding acquired skills in the process. Months were necessary to simply perceive some vague impressions in the begining, which is why i kept tweaking for years, literally. Besides such aspects i should equally mention that i exploited my own limitations as a "radar", trying to figure out when i had reached one boundary of an applications range that seemed to "move" with time. In other words there were human variables in the equation as well!

    So, the reason why i called it a "Hybrid Core" simply revolves around VG's contrasting monolithic design: based on 1 single SiC Puck. That's 1 component with only 1 set of properties. My core has many.

    At 1st i thought of the "composite" label but feared confusion so that's how the word was prefered instead. A set of materials with very different properties are juxtaposed and this causes interesting hybrid properties to emerge that weren't possible before. Creating a "solid-state" heat valve operated by airflow: shield (and temporary storage) when idle, radiator when dynamic.

    That's a relevant question, i just wish i could compare with the genuine VG pipe. Yet i'd have to reply there are 2 modes: "Plan-A" with Induction Heat as the main power source, then "Plan-B" where butane is a fall-back option with stirring made necessary. N.B.: "Plan-A" offers provisions for ultra-sonic stirring, at least in theory.

    Truth is i failed to operate my 1st genuine VG pipe in 2012 and never succeeded with a few more tries ever since. By chance it made a lot of sense to pick VaporGenie for their selection of materials which proved most appropriate all along. It's a mystery to me how the company appeared to stop development before they evaluated a hybrid core of their own.

    Anyway i realize there's been so much modifications it won't hurt posting instructions. Hence here come my "10 commandments" (...):

    0) About Bowl loading, Always Fill and Never Pack. Keep in mind the Support Loop located right under a pipe's Cannabic Bowl needs to be "flipped" after removal as this greatly eases reinsertion, simply by screwing it in clockwise. Bowl size/weight is ajusted using that Support Loop.

    1) With butane and/or it's related compounds present in the lungs path just make sure there's ALWAYS a clean burning flame to convert butane from such stream into relatively safe superheated Water Vapor and Carbonic Gas, while taking care to inhale with much less force (by lifting the thumb over a pipe's PinHole) to pre-heat the Hybrid Core of a customized Sphere.

    2) NEVER let a flame touch anything as this will result in the addition of soot plus other nuisances. All that is required to be captured by the Flame-Catcher to inject a "Heat Charge" (or "Energy Bubble") has to do with the Energy-Carrying Exhaust + some Radiative Heat.

    3) NEVER light up or extinguist a butane lighter close to the Flame Catcher. Flint-Wheel Yellow-Flame models generate health-hasard particles in the spark while the Blue Flame ones may fail to consume butane cleanly (extinguish at random and/or spitting out liquid butane droplets not converted by fire)... Briefly put, ALWAYS wait for a flame to stabilize before it's taken close to the Flame-Catcher Aperture.

    4) When a primary PinHole is available lift thumb during Pre-Heating. Once the Sphere is sufficiently energized, e.g. between 2~5 seconds depending on a butane lighter, use its stored heat which has just been temporarily injected into the Hybrid Core WITHOUT any butane and/or related stream present near the Flame-Catcher Aperture. This indirect/residual energy-source alone suffices to proceed with the actual Vaporization process.

    5) While vaporizing try obstructing the PinHole in brief pulses, in very short bursts at first then increasingly longer to compensate for lost heat from the Hybrid Core as its energy reserve gets depleted. The periods with no PinHole-obstructive thumb in action contribute to oxygenation of the cannabic stream while promoting early detection of vaporization signs, especially hints as aroma/taste. Think of some method vaguely similar to "pumping" a car's breaks in an emergy maneuver situation, the goal being to probe using a sequence of short pulses instead of attempting to get it done in 1 single long pulse. The start/stop transitions appear to cause turbulence which helps with stream movement.

    6) A ~125 mg Bowl provides about 5~6 tokes, the left-over can be made useful at a later time to produce relaxing cookies. Don't forget that once in a while even an empty cannabic Bowl can provide some satisfying toke (or two) from a sticky screen alone. Evidently stronger cookies should result from leaving more THC behind from vaping. These days i just vape it dry: used vegetal substrate falls off easily...

    7) It's time for cleanup maintenance when the pipe stops working as usual. Pick a pipe stick wetted with 94 % pure grain alcohol to clean wood VG Handles fast. NEVER allow the wood to absorb water as this would promote cracks in the wood. Metal models are to be prefered when condensed noble molecules need to be "reclaimed", though these feel heavier in the hand while wood's near organic-like aspects would prove more "sexy". Alternately, wood is an absorbing material so this makes it less desirable if/when resin reclaims are desired. The back face of metal pipes proves handy for quick torch-cleaning of a screen with no risk of a skin burn. Choose the "Classic" look Aluminium for superior aroma/taste performance.

    8) Initially i found the genuine layout with VG's DuckLips MouthPiece was getting uncomfortably hot, the addition of a half-ball stainless steel object down under my cannabic Bowl paved the way to lower-temperature cannabic vapor being sent towards the lungs; as an option it may also help to capture particles in the cannabic vapor using a tiny cotton ball which somewhat adds to the cooling action after getting moist. This half-sphere screen was gradually dropped in more recent versions though, in favour of an auxiliary PinHole located on the MP base...

    9) When attempting to reconfigure DuckLips MouthPieces to reflect the side-wise preference of an operator (e.g. right vs left rotation) try to never forget about twisting it lightly while pulling on it with care as its stem proved very brittle. Somehow an helix motion seems more gentle.

    10) The need for eye-contact on a flame tip may require some Flexible Plastic PVC Tubing Extension. A length of 12.5 cm will do and that's a better place where to install the optional cotton ball (strongly recommended), unless a plastic/metal Mating junction is available of course. Last but not least, clear plastic makes it easy to monitor butane consumption based on water vapor condensation creating droplets in the tube after a potential abuse situation, or operating error, etc. The Tubing Extension will opacify if/when abuse continues, ultimately. End the session and re-evaluate operator skills if this occurs, don't forget to shake off liquid water droplets after removing that tube. Consider this a true "Harm Reduction" self-awareness feature.

    Good day, have fun!! :peace:

    NOTICE:



    Pictures from PostImages are "broken" today, for example:
    A temporary remedy is to replace its "org" domain with "cc":
    Another possibility is to switch back to TinyPic, though its lack of reliability was what caused me go with PostImages in the 1st place...

    Now trying it anyway:
    M'well, lets hope such inconvenience won't last...

    Update



    This is the fix for a previous broken picture link:
    That pretty much illustrates the essential changes while this revised diagram below expresses its revised associated "ritual":
    Very little succion force is applied initially as i only intend to pre-heat my Hybrid Core, or at least faster than i pre-heat my vegetal load anyway. Once a satisfactory red-hot spot is obtained in that core's silicon-carbide (SiC) Front Puck i know visually that sufficient heat got stored. The flame can be removed then the final process begins, at 1st actually heating the bowl before it starts producing a cloud for inhalation. The pumping action promotes movement of the noble molecules collected in the path. It's also a way to prevent early hot-spotting.

    Good day, have fun!! :peace:

    The Problem:

    [​IMG]
    Tiny trichome glands conveniently collect nature's gift on a molecular basis, right at the site of genesis... Hence i find impossible to imagine any man-made "filtered" alternatives of comparable quality being delivered at such little cost!

    Only, there's a catch: we'd want to extract the goodies and the goodies only.

    :hmm:

    By chance dame nature gathers those noble droplets as a delicate layer supported by vegetal substate of contrasting mass. Even after it's been shreaded in a grinder (upper-right corner) the trichomes remain relatively tiny in comparison...

    [​IMG] [​IMG]
    [​IMG] [​IMG]

    The solution:

    [​IMG]
    [​IMG]

    ...

    [​IMG] LAVA!

    More cuts to perform:

    [​IMG]

    The Hybrid Core:

    [​IMG]
    [​IMG]
    Be advised this is where the "PinHole" of my "Prototyping Platform" still needs to be relocated today (...), in order to further reduce delays, to promote enhanced "conservation" by bringing "baking" to an absolute minimum via fast heat removal that's as quick as a heat burst can be.


    "Plan-A" (IH mode):

    [​IMG]
    [​IMG]
    In Induction Heat mode it's just too easy to multiply "susceptor" (IH) elements if/when convenient. For example, in Near-Symetrical "capsule" scenarios it's no problem power-driving 2 Hybrid Cores instead of only one, which doubles available "Heat charges" and consequently bowl size/weight. As a bonus it also becomes tempting to implement analog heat control by adjusting airflow as a function of a core's Curie point, which in turn determines stored energy by virtue of mass, specific heat capacity and temperature... All it takes is a way to control the mix between 2 fixed references, no complex IH Driver required: simply inject "Heat Charge" until Curie "saturation" point.

    :cool:

    Now lets divide vaporizers as 2 groups, the "Mainly-ON" which correspond to classical thermo-static designs i call "Hot Dry Air Ovenizers", then the "Mainly-OFF" type as presented in my dedicated thread. One device gets heated over long periods (with plenty of energy wasted in parasitic leaks...), the other only heats up for very brief moments on the contrary.

    M'well, this may be a most interesting difference when it comes to heat vs mass: propagation of heat in matter isn't instantaneous, there's a delay. In other words tiny structures thermalize 1st.

    :nod:

    At least that's what my experiments with "Micro-Bursting" appear to validate: paradoxically, improved aroma/taste appreciation results from more risky (shorter/potent) heat bursts. The trick is to exploit "Packetization" in a way to match the temporary "Heat Charge" and its cannabic "Workload", which is to target that delicate sugar layer previously illustrated while attempting to leave its associated substrate relatively unaffected - or at least to delay "baking" which causes all sorts of compounds present in vegetal tissue to infuse, reach the contact-surface then melt, ultimately...

    Though tricky ain't synonymous to impossible. Hence my proposal is to develop a consumption method where the heat front is strong enough to challenge noble contact-surfaces while it's still too weak to significantly interact with less noble plant material (or delay such interaction sufficiently to be done with extraction by the time a whole bowl starts to look 'n feel roasted). It's sort of reminding me about ice cream degustation: some people like to take bites into the solid, others prefer leaching of the melting surface.

    :D

    Anyway i came to conclude that no "Hot Dry Air Ovenizer" can pretend to offer access to a similar challenge; it's frozen in a static thermalized perspective while my LAVA engine concept relies on transitory dynamic properties capable of bridging this gap i believe.

    :2c:

    I've noticed the same thing with my Newvape Flowerpot Showerhead and have been talking about it for months, preserved flavor at higher temps, utilizing short micro bursts of heat which can completely milk a tube in seconds.

    This is at 777F

    Salutations Invertedisdead,

    Nice to meet you! :D

    Indeed, i have no difficulty to imagine it happens; actually i may be familiar with a similar feeling. :nod:

    And there's more... What i came to call the "Release/Transport Agent" for example, e.g. where Inlet Water can be expected to make a significant difference between "Hot Dry Air Ovenizers" and my customized "Clean-Burning Butane" VG pipe: my exhaust gases are a mix of super-hot H2O + CO2, seasoned with comet dust (15 ~ 30 ppm) i must confess, which finally implies that my "Release/Transport Agent" has its specific heat capacity raised by the addition of water vapor to dry air:

    Only a tiny amount is involved, maybe it's a modest boost something like 20 ~ 30 percent, i just don't know, but i'm certain it's still a boost clearly above 1.0 nonetheless - hence me calling it "Potentialization".

    So, believe me saying i'm not very popular when i suggest that clean-burning butane provides both inlet self-moisturization and potentialisation altogether. Yet that could be of importance and most specially in a "Micro-Bursting" context, because quick is better as i've observed myself (and/or zero "baking" is best)... So, to me that means such potentialisation suffices to conveniently compensate for more compact bursts, by carrying more energy than hot dry air alone in even less time, to limit heat propagation, eventually baking, etc...

    :science:

    It wouldn't be challenging to convince me since i can believe this as well. Lets just not forget it's all dynamic when convective/radiative heat assited by conductive heat set things in motion...

    Yet my LAVA concept is aiming for some pocket format reminescent of breedings between the FireFly and a FlowerMate or E-Livi8: flat, rectangular, battery-operated with a telescopic straw, no display and only 1 power switch, etc., etc. Self-moisturizing option by the addition of distilled water droplets, with potentialization of my release/transport agent as a bonus...

    What i'm saying is that we may be observing the same phenomenon at different scales. So, yes, i can believe it after all. At least it shows how 1st-hand experience influences perceptions.

    :tup:

    Good day and thanks for sharing the fun!! :peace:

    I actually saw you post about this in another thread recently and have been messing with butane powered concepts at home. I don't have tons of experience with this type of butane vaporization yet, but so far, I would tend to agree that I notice some smoothness from the water vapor!

    That I can believe!! :D

    But the naysayers should know that this method comes with the most potent vapor signature!

    Full spectrum!! I like that :)

    Thank you!! It's truly a strange phenomenon, better flavor at higher temperatures, but I'm on your side, there's something to this "flash" vaporization.

    Hi there Invertedisdead,

    Actually if there's an IH vape on the desk then my guess is that most potential owners will want to try a "Plan-A" 1st, even if "dry", and then eventually forget about "Plan-B" - unless it may come handy, for example to seek aroma/taste features (at the moment i hardly imagine pocket IH "Micro-Bursting" competing with "Plan-B" for high-power applications). That makes "Bi-Energy" a valuable asset as even a jetable Bic butane lighter from a local store will do fine...

    It's not an easy idea to explain. There are practical reasons in favor of fire compatibility; injection of a "Heat Charge" even via a clean-burning "jet" butane flame doesn't actually require a human operator to expose his own lungs path if he prefers not to. A pump inside the IH Driver can handle the "Pre-Heating" phase, but what for?! Visualize it: in IH mode we don't have to rely on a convective heat vector at all, energy can be stored in the Hybrid Core(s) while still in iddle state, in absence of any airflow.

    :nod:

    On top of this the dual-core capsule concept invites post re-vaporization, i believe. Which also doubles as a simple self-cleaning solution, by reversing the capsule once in a while. Nothing will stick there for long and microscopic flying droplets in the cannabic stream would shrink even further i figure: combining self-moisturization to less harsh trimmed-down cannabic particules.

    Anyway, back to water as an option, a majority of future vaporists do not have to worry much about it, lucky them. It's not mandatory but i wish manufacturers were more inclusive.

    ;)

    I think "the shortest path of lesser transformation" accurately describes it, as for appreciation in terms of rich aroma/taste and also some generous cloud opacity i'd say it's simply a matter of matching energy and mass. At least i know it doesn't take much to reach an application range where securely sitting on a chair is a pre-requirement, because of what i tagged the "punch-in-the-face" effect, with a shrinking vision tunel, etc... As a matter of fact i had to deliberately tame down the output, as it was too "destructive" when connected to a water toy!

    [​IMG]
    Cheap and effective, but it lacked balance if i may say so. At least i did as i recall!...

    :p

    In a static ovenized setup, m'yeah. But i'm assuming a burst of energy carried by a combination of convective and radiative vectors, with some conduction made usefull in pre-heating a bowl, ideally.

    :science:

    Does the vegetal mass have time to over-heat starting from the moment it becomes volatile?... Distances are extremely short in my Hybrid Core, the Top-of-Bowl SiC Puck is only 2.4 mm thick and the SiC cells contain air pockets which rise in temperature as it gets closer to my 1 mm thick Metal Disc (the one with seventeen #53 holes)... Passage through this "heat-valve" barrier is real quick when inhalation begins.

    Past the bottom-of-bowl screen there's a large auxiliary cavity which traps particles, apparently by virtue of its vortex action. In any case i doubt temperature continues to rise at that point, quite on the contrary: constant direction changes due to turbulence only accelerate thermalization while heat is converted and dissipated, possibly with a delay. Now lets include a tiny cotton swab in my pipe's Mating Junction, plus the PVC Extension Tubing where excess moisture is condensed and even absorbed by the clear plastic which turns "milky" translucent, with droplets collecting on the inside surface, etc...

    Does a pulse's heat front continue to bake my noble molecules after vaporization set those free and they started leaving the bowl through underlying cannabic matter, etc??

    :sherlock:

    It's a dynamic process, i'm not so sure the vaporized substances still heat up once the "Release/Transport Agent" captures/carries them away... If my assumption is correct then this may be a reasonable explanation about how i manage to get satisfied using so little vegetal mass when i used to need 5 ~ 6 times more. 300 mg bowls were not rare when i was "electric" and i recall this became too wasteful to continue as i often felt short of breath, more and more. A solution was required and i got one to hold onto at last!

    :cool:

    It's been a bit tricky getting there but i wouldn't want to regress, flash-vaporization evokes the right images, or try fry-vaping perhaps. There's a reason why i eventually adopted a kitchen-size torch: it was because i needed a steep energy input in order to explore shorter bursts. Excessive but also informative, though with IH mode ahead i'd favour just rising the Curie point until the Heat Charge matches its workload instead.

    At the moment "impossible" would sure sound premature!

    :D

    Good day, have fun!! :peace:
