Salutations,

Here's my last 2022 drawing providing an overview on IH aspects of some long reflection that still causes me immense regrets today, especially because of the potential remaining to realize:
Egzoset-s-Primordial-2-Sided-General-Purpose-Backbone-for-Cig-Pak-Cube-2022-Feb-4-960x800.png

The image itself still contains errors, it was mainly intended to fuel eventual discussions that never started, unfortunately. At best 2 or 3 rare braves would politely argue they feel intimidated while the rest will promptly express their displease through a typical consumerist reaction, always in extremely vague terms nonetheless.

:shrug:

A brief search on Google tells me that we now have an option to acquire non-rechargeable batteries capable of providing about 3.6 Volts @ 2600 mAh in 14500 format, which amounts to a grand total of about 7.2 Volts x 2.6 A = 18.72 Watts in peak burst mode. So if we account for energy conversion losses, say 15%, then that's 85% of 18.72 or 15.912 Watts (max).

Let's round it up to 15.9 Watts trying to estimate warm-up time, i.e.: 100 Joules ÷ 15.9 Watts ~ 6.3 seconds for a single Hybrid Core (made of a « susceptor » sandwiched between a pair of SiC layers), or else 12.6 seconds for my 200 Joules LAVACapsule design. All fitting into the volume of King Size cigarette packs...

Too bad today's rechargeable cells continue to cap under 900 mAh, which would stretch the preheating time by a factor close to 3. In other words we'll need to wait for energy densities to increase before such novel idea becomes viable from a user's point of view - who by the way will certainly refuse to pay $40/2 cells, not to mention those got to be rendered suitable for power applications lasting at least half a minute just to guarantee a reasonable safety margin.

M'well, lets not despair: « It's already been done before, just not yet!! »...

My previous drawings mentioned the use of magnetic flux concentration to compensate for my previous aerial windings, i'm talking about raising the bar to 18 poles in a double-sided version instead of only 1 for an air-core selenoïd whose single field is only aligned to its central axis. In comparison, the transition to 3 dimensions should greatly increase sensitivity to microphonic effects (in the presence of permanent magnets, illustrated in blue). Not only would a pair of Hall-Effect current sensors help to implement effective over-current protection, in addition their galvanically-isolated analog outputs can provide an I•Q signal suitable for synchronous quadrature demodulation, e.g. quite enough to capture tap-commands given directly through the consumption tool itself, hence without any need for other buttons - nor even any display or LED for that matter, since one may also assume this could make it possible to induce audible vibrations into that very same handle-shaped tool. In other words i foresee some novel solution suitable for a group of customers ignored by an industry where it's expected of all clients to have equal ease to use their visual & tactile/manual capabilities.

Finally, since the laws of dame Nature are immutable, it becomes imperative to make the most of these starting with this simple formula:

Specific_Heat_formula_300x200.png
Q = m•𝛥T•Cp

Considering the mass of an IH heating element never varies and we totally control the amplitude of power pulses this implies that such technology will someday allow designers of the future to precisely dose the amount of energy in plain accordance with a desired « workload » size for each inhalation, thus offering individual consumers a real opportunity to multiply their chances of experiencing something other than just systemic dosing abuse as with the "joint" which we tend to finish until the end. In conclusion, do more with less!

The bets are open. How long do we still have to wait to witness the future come true?? 🤔

Good day, have fun!! ☮️
 
Are you suppose to put your weed in it?

That certainly was my objective, or more precisely to insert a « LAVAWand » consumption tool carrying dry flowers inside.

My customized VaporGenie pipe is made of metal but i see no reason why the same Hybrid Core structure wouldn't work fine after being adapted to a glass tube shaped to accommodate structures as these:

Egzoset_s_Lava_Wand_Concept_-_Capsule_2017-_Apr-22_150x120.png

Above that's my basic Hybrid Core with an energy budget of 100 Joules, below a quasi-symetric reversible LAVACapsule requiring 200 Joules:

Presently my pipe's pre-heat time is 1 second (typ.), so this « bursting » method & ritual removes a great deal of heat stress rendering materials selection a lot more convenient. In addition, there's also the possibility to divide an overall energy budget in 2 phases like when trichome glands are replaced by a concentrate previously sprayed on some porous (aerial) substrate...

If somehow dry flowers should proved more power-hungry than expected then at least it can fall back to processed extracts working much like popular e-liquids, with the difference that i'd want to deposit a thin layer of mine on a large contact-surface instead of wastefully target one massive blob with crazy amounts of heat (in dabbing fashion).

Well, to me every Valentine's day is a reminder of 2011 when i finally initiated myself to vaporism, just the day after.

While there's people who keep juxtaposing cannabis and sickness i feel more like celebrating, except this year i prepared no publication simply because it's all been told and shown before, though elsewhere with no audience.

But sometimes a nice surprize awaits at the corner so i guess it's OKay sharing that here, in a few words, simply as a topic complement meant for some reader of a distant future when hobbyist activities gain popularity again.

About 8 years ago i read a datasheet reporting that Allegro's ACS733 chip could manage galvanically-insulated surrent sensing in the ranges of ±20, ±40, ±65 and ±75 Ampères. Lucky me, somehow my attention was instantly captured yesterday: Infineon's TLI4971 now offers similar functions rated even higher at ±25, ±50, ±75 or ±120 Ampères, with a trade-off on bandwidth. And the best part of it was that i found out by reading another paper, this one focussing on Induction Heat, though the domestic type around 3 KW! It wouldn't go as far as phase-coherent quadrature demodulation applied to "scanning" of the workload and yet my imagination felt renewed by it, as if Christmass had waited February. Eventually a DiY adventurer will align the dots and see how such Hall-effect chips can pave the way to a synthetic "Royer ZVS" topology no longer prone to self-destruction after it's got the FlyBack transformer stripped away (...), e.g. with protections built right into its twin power stage while remembering that the invisible "clever" trick about this resided in magnetic saturation provided by a flux concentration core made of material normally rejected in other types of applications. At least that's how i vaguely perceive this future might eventually unfold, with my fingers crossed, wishing for the best.

Good day, have fun!! ☮️

Recently YouTube started making sense again. This time by referring to the « Tayloe Detector », based on a pair of SP4T (dual single-pole quad-throw) FET multiplexers/demultiplexers, typically a 74xx3253 CMOS variant resulting from a technology in perpetual progress that is still inspired by the old 74xx digital series (though in this particular case also integrating a novel analog function). The 4052 which allows a much higher supply voltage resurfaced as part of my search results as well but clearly didn't enjoy a same popularity, quite possibly because of its relatively poor ON-state channel conduction i presume.

Anyway please pardon me such exotic parlance, hopefully the cover image of that 3-parts sample will convey my point more appropriately:


Software Defined Radio with Pi-Pico @ 1:24 (2024-Aug-11)​

I suggest to forget about the right half, in other projects they relied on the Si5351 chip for their clock reference, etc. IMO the one aspect of importance here is SIMPLICITY, while the signal to be "received" ain't even any real radio at all (it comes from inside a very same casing and there's direct access to its main carrier already). The oldest related YT publications i found seemed to date back to 2012, i figure microcontrollers just improved significantly in the meantime, hence the continued interest.

An induction heater operated through its consumption wand itself would require no display, while smart features can be supported externally anyway; and all we need is a power switch i guess, i.e. a combination of tap commands + haptic feedback should suffice. In addition, i keep thinking the Royer ZVS already divides each cycle by half, so perhaps the SPDT 74xx3257 version or equivalent would be fine enough. Actually those chips evolve too, the old ones getting discontinued and replaced by new solutions that include power up/down protection, a better ON-state conduction, less parasitic capacitance and less device power consumption, etc., etc.

As a side-note, lets pay attention to how much space got wasted in those YT prototypes: how much is really needed? Would it not fit the King Size cig-pak format...

Good day, have fun!! ☮️

Love your threads you know so much,
first sentence i m lost, i would have to take hour s to just
get a grip on whats written. What is probably very interesting.

Your a scientist, and good writer with very thorough made posts.
They make my head spin, in the morning.
 
Love your threads...

It sounds like i should thank you, for another opportunity to add some complement i guess. But the main point here never been about focussing on the topic's poster instead of his subjet(s) alone...

What i do intend to accomplish has nothing in common with projecting some personal image and everything with planting a seed of inspiration. Technologies evolve and some of what's sci-fi today will become realistic tomorrow, for example replacing 18500 power cells with the smaller 14500 size without a need for any trade-off, except gaining space and trimming excess weight.

All i can tell from my own hands-on experience, after evaluating many iterations implemented in a series of prototypes, is that the energy budget of famous products as the Vestratto Tornado went out of control at 3250 Joules while i rated my Hybrid Core at around 100 J (maybe twice, maybe half, but i sure don't expect a mistake as bad as a 5-fold margin error). In addition there's also the « HR » factor which ain't being accounted for in most of the ready-made consumption designs now commercialized, quite the opposite: at 3250 J the Tornado's dense monster clouds promise to send vulnerable users right into the tolerance spiral. That's no big issue for medicinal applications where severity of an ailment has priority, but i'm also thinking of the recreative side.

So far we yet have to see 1 single IH driver taking full advantage of such promissing technology and that's a shame, considering IMO one key to "safe" inhalation delivery resides in closely matching the amount of energy with its workload - and i can't imagine a more appropriate solution. 1st of all it's wireless, which means a simple glass tube requires no holes drilling to insert any wires. Next, as i previously mentioned, the energy budget is a result of this fundamental law of nature:

Q = m•𝛥T•Cp
Where Q is expressed in Joules, m in grams, 𝛥T in Centigrades and Cp in J/(g•°C); more precisely, if we dare question Google with these 2 strings it will figure out how to respond quite directly:


Suspect no grandiose mystery, not even some freemasons secret, etc! Only an ability provided by knowledge which is accessible to the masses, probably right now in your pocket. In my present example it's asking Google about the "specific heat capacity" of strongly magnetic stainless steel, an ideal candidate for induction heater missions.

Better yet, try this variant:


And since all those factors are linked i'll admit that's how i came to the 100 Joules number, then allowing me (much later) to point a finger at the severe waste of energy typically resulting in systemic exposure to dosing abuse, e.g. one major topic of this cannabis-dedicated forum.
