Yes, a patent gives you grounds to sue, but what federal judge or jury is going to actually enforce this or other such overtly weak and device/design-specific patent? And the costs of going to court would be far more than any financial damage a competitor could do. Add in that most vaporizer...

If approved, which would ultimately be a political decision, FDA will surely require tight controls on its marketing. In fact, like an increasing number of new pharmaceuticals, particularly those for orphan (niche; specialized) indications (specific uses; small patient populations), such as to...

From my limited experience with patents, mostly biotech/chemical, the MF and most other patents for vaporizers are a joke, i.e., rather worthless. First, the Magic Flight Launch Box-related "patent" linked to is just an application, so nothing has been granted and there is nothing that can be...

Isn't d-limonene a DEA-watched, if not controlled, substance? Isn't it (along with olivetol) a classic precursor for THC synthesis? It might be foolish to purchase d-limonene without considering this. At this level of cost, danger and sophistication, why not just use surely much safer CO2...

What are the inner and outer diameters for the various popular log vaporizer cores/output pipes and their stems? There are references to 3/8" stems and cores, but aren't tubes fitting within tubes, so we need to pay attention to inner and outer diameters interfacing with each other?

You didn't say anything about your age, situation (e.g., married, with children to support?), level of education, interests, skills, etc. I would generally tell anyone not sure about a career and, presuming that they still are or think young enough and their personal situationallows, to go...

The active agents of interest are definitely liquids at room temperature, particularly when in a purified state. Viscous liquids, even referred to as oils, but definitely liquids, which can be poured and vaporized [or synonym - thermally desorbed, volatilized, etc.] into a gaseous state (which...

Can you tell us more about what you are thinking of? It sounds like you want to keep it simple. Do you want a consensus Eterra/PD/MZ/UD/etc. copy in kit form; maybe clone the prior PD kit (with a few fixes)? Must this be an actual "log" vape (requiring a lathe, wood-working tools, a real...

I think the following extract from the chart cited is very plausible and likely accurate. "When a breastfeeding mother smokes [or vapes] marijuana, THC (the active component of the drug) appears in her breast milk in quantities that can reach eight times the amount in her bloodstream. In...

Obviously, follow the advice of the manufacturer! But one option for variable temperature is a power adapter at the higher-end of your UD's specified range (e.g., 13, 13.5 or 14 volts?) with a ?$10 solid-state DC dimmer switch, such as meant for cars/RVs/boats and LED use. For example, see...

Regarding "no point in discussing modifications to a product that will no longer be produced," there are many PDs out there and, as kit owners can likely confirm, modifications shouldn't be that hard.

Rather than quoting what has become simply too much text (am I violating FC rules by not doing this?), regarding several persons being perplexed why I would promote discussion of PD problems, modifications, upgrades and innovations, I say "Why not? Aren't these among the topics we should be...

Regarding my labeling the PD a "knock-off," I used this in the sense of it being an outright copy (admited by Tom, as I recall) of the Eterra (and/or another log vape manufacturer's knock-off) with the only or main improvement being the addition of "fins" (which I think could be further more...

I posted this as a serious post from an individual. There simply is no more Purple Days. It's time to move on, which includes discussions of topics, even technical topics such as I bring up, that simply were not welcome here before. Let's talk about about the PD itself, and how to make PD's...

The PD is history, perhaps to be known during its time on the market as the most popular log vaporizer (Eterra knock-off) with a reputation as a good product. Maybe it's getting time soon for this thread, entitled "Purple-Days Experience," to be closed. The "Experience" part (Tom) is over...

Rather than buying a variable power supply, which is overkill, see my postings above about simply using say a 13-14 volt adapter with a simple $9.95 12-14 volt digital dimmer switch. And the same dimmer can also be used in your car.

Herbal vapors naturally include a variety of essential oils, terpenes, chlorophylls, phenolics and other plant components that can cause irritation and other local tissue reactions, particularly if you or the tissues happen to be sensitive. There could also be other components acting as...

The desired herbal components are not in a solid state. Rather, they are notoriously sticky/gunky essential oils (liquids) that strongly adhere to most any surface, cellulose fibers (the structural component of plants) in this case. "Vaporization," as the term is used, really involves two...

On the other hand, why buy another vaporizer when you can vey simply and inexpensively make the vaporizer you have better? Shouldn't log vape owners who want to be able to fully adjust their temperatures (i.e., power supply) throughout the full range allowed by their manufacturers? And...

I've never understood all the problems users and even manufacturers have with making log-style (~12 volt, hand-held, convection) vaporizers temperature adjustable. Perhaps, there is a middle ground that everyone, even manufacturers, can accept. What I propose is useful for those wanting...
