    Discontinued The Persei Vaporizer for herbs and concentrates.

    OK, I'll bite - I'd guess a partially insulating cylinder that fits inside the heat shield around the base of the inner heating element, below the concentrate tank, which acts to direct more of the heat upwards to the concentrate tank; Something that looks like a cut-down sewing thread spool (...

    I think you just gave the reason BlueSurfBoy couldn't use his Persei reliably - Those are the WRONG batteries. They are the right ones for most ecig "mods" that use a single 18350; He probably bought them from some ecig site. In order to "stack" cells, you need to either use "nipple" cells or...

    Discontinued The Persei Vaporizer for herbs and concentrates.

    There is a large power difference, but not enough to explain a factor of three in time. I suspect you're close with thinking about insulation, but I'd go further and consider how much of the energy is transferred by conduction, where insulation matters, and how much is transferred by IR...

    Protected mode cells are allowed .5mm of space in the diameter to account for the wire or ribbon (in better brands) which connects the bottom terminal to the circuit board at the top. This connection runs under the wrapper the length of the cell, If you peel a protected mode battery, it can...

    Boy, go away for a day.... One problem is I believe the OKR parts are step-down/"buck" only. I originally suggested one for a 6v supply from automotive 12v (or 13.2 from the battery or 13.8 from the alternator). I'm pretty sure that those regulators require a supply voltage just a bit more...

    The Prodigy line is made in TN, and uses the same 17670 or pair of (R)CR123As as the TV current large handle. All mechanical and seems very well made out of steel. Thewall420 is correct that the batteries are "Lithium Iron" - more specifically they use "Lithium Ferrous Phosphate" as the...

    Even as an ex-smoker, I'm not sure it is quite so clear. Nicotine does have many positive effects; One review article is: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3151730/ There are reasons why people, even like our POTUS (no political meaning intended) have a great deal of difficultly...

    Everything already said about the cleaning is correct. In my experience, no cleaning is needed when they arrive. One very important thing hasn't been mentioned yet: Weight the cart new, fresh and empty so you know its weight (and can tell how clean or at least how much the residue you didn't...

    DR, Two questions: Can you test if the unit works? If it can heat a cart, it most likely is fine (dsb said it was intermittent and mentioned his brother, a student at ?UCB gave him a rationale) - easy test (besides, it had been supposed to have been just returned from D9 for...

    Also, a jar of fine powder activated carbon, a Buchner filter and a good aspirator will turn black chlorophyll oil back to nice amber (but it takes a _long_ time). -NDA

    Discontinued The Persei Vaporizer for herbs and concentrates.

    I mentioned that limonene eats silicone. Teflon/PFTE is fine (but not as inexpensive, or as flexible as fluorinated rubber). How much a DART can hold is a matter is how much you want to abuse your batteries and possibly the oil. The past two weeks, when I go out I've been loading 1/4 to 1/3...

    Discontinued ThermoVape Revolution for concentrates

    I've been thinking along similar lines. Mostly leaning toward something like a wire plunger and tube injector, but I *really* like the idea of turning a piece near the top. Mechanical things can be so much more difficult than electrical or electronics. I don't think anyone else has said this...

    I'd have guessed you'd have already known this: d-limonene is sold specifically as a product to dissolve (i.e. clean up) silicone monomers and mold flashings. ex.: http://holdenslatex.com/pdf/specproducts.pdf http://www.sculpt.com/catalog_98/moldingaccessories/d-Limonene.htm Normally...

    I know we've all been seeing all day the back and forth between bluesurfboy and DubC (among others). Hopefully we can drop this. Unless I'm mistaken (quite possible) it seems that bluesurfboy sold his Persei to darkrom (mentioned in Universe post #848 and discussed in the classifieds) . And if...

    Does this mean that the Omicron version of the Reactor will come with yet another V2.x head to raise the current limit up? Or will the new HVDs have 5 Amp limits? Actually OF said "trick", not "fool". Still I can think of two approaches to actually do this. Cosmologically, you could use either...

    Just remember, "Better, faster, cheaper" - pick any two. It is easy to get two of three; Any decent engineer should be able to for you. Achieve all three and you've "built the better mousetrap" and you can expect to have a success. -NDA

    [ Well... My preferred battery for the LV DART is the Joyetech eGo-C Twist - a cheap Chinese battery. I own a pair of LVs, both were bought without any Thermovape supplies (my SV was). Unfortunately, for the time being, purchasing a DART is "difficult" (you'd need to by the pieces separately)...

    Let me add that I worked for a time as a chemist. When I had my first serious fire (predicted by my adviser, I was attempting to duplicate some work published in a patent - patents both lie and usually omit critical details), a cohort put up in my office a poster with the line "Real Chemists...
