I think it has a better time with the nichrome because it's smaller and can absorb the stress without cracking, but the 24ga was just too much.

crip posted some information a bit back on metal-to-glass seals. One that you might be interested in is thin copper tubes. You could possibly even crimp the Nichrome within. Since it's a hollow cylinder it can absorb more of the force against the glass (hopefully!).

The thermal expansion of Nichrome is 13.4ppm/C while Copper is 17ppm/C. They're fairly close so I'm guessing the main problem with the current setup is the gage of the copper.

Based on 38ga nichrome and 24ga copper, the nichrome expands by 1.3837*10^-6 mm/C and the copper will expand by 8.687*10^-6 mm/C (that's a factor of 6.28).

Hope this helps, I'm off to ebay, google, and amazon to look for info on tiny copper tubing....

I like the looks of the pyrex atty, but can't figure out what I am looking at in the 1st picture... :-(

[moktarino]

It's just you.

The first picture is a test of my atty using my patented capillary feed tube system.

It's not really patented. It doesn't work that well, either, if there's a little bit at the bottom it won't fill from the top, so don't even bother thinking that this particular implementation holds promise

Hey guys, Eric the neon bender gave me some examples of wire with almost no resistance crimped in glass. He cooled them in a pan of stuff that looked like kitty litter. He said slow cooling was the key to avoid breakage. I have 4 roughly 3/8" ID tubes he crimped closed around some tie wire for neon. If anyone is interested, PM me and I can take pics or send via mail. He is willing to make "glass elements", for lack of a better term" or anything else we might need.

Roadkill, I think one of the keys to a better design is to create a vaccum to draw the e-juice to the heat source, Put a tip on the glass and you have an insulating cooling area.
I like M's pyrex experiments too. He seems to be on the right track.

I should have the materials for my experiment next week, Eric supplied me with the glass chambers, the rest will be mechanical build...

An interesting aside:

I was doing some patent research into PV's (more than a hobby....).

Many of the things that have been discussed here and elsewhere... micro-piezo droplet control of the e-liquid, Tinel memory-metal release of e-liquid.. capsules.. etc.. have already been investigated and to some extent patented by Ruyan. Hon, Lik (Ruyan) has patents and patent applications on these items going back to 2003. There is some very interesting reading in some of these patents (user information displays.. etc..).

Makes me hope or believe that a better generation of PV's is on the horizon.

A picture of the these would be nice

Could you please elaborate on the vacuum idea?

Glad to hear you were successful with locating materials, we need more people doing more experiments! Don't forget to post all of your results! And with pictures!

kinabaloo has posted many times the suggestion that we use piezo droplet control (like an inkjet printer does). I have not heard of Tinel memory-metal though. Did you find anything cool that also sounds doable as a DIY project?

Wow! These are some stimulating ideas y'all. I don't pretend to be anything other than someone who enjoys puzzling but if y'all don't mind I'd like to lurk around and pose a few thoughts as these projects progress.

As for myself, there is nothing I can't over-engineer. When I design things I tryyyy to mantra the classic "Form follows function" and "The fewer parts the fewer potential problems", and I still overkill. Drats. But I ain't afraid of no steenking drawing board!

In order to mod I'd have to constantly remind myself that my bottom line aim is proper vapor temps delivered in pleasing amounts. Major bonus points for any extended batt, e-liquid, etc., lifetimes beyond what is out there now. Which is why I came here... to see y'all's approach. I have a niggling feeling you can't have it all ways, but that it can be done much better.

OK, I read every thread post (I think) and these thoughts spring to mind:

On the glass mod, what vapor temps are coming off the models that have been cracking and can burn cotton? May just be an issue of too much heat within the mod. If the vapor temps are too high the problem might be approached by shortening the coil length one half twist at a time until the glass ceased to crack and checking the vapor temps at that point. But it seems to me that if the vapor temp range and glass sustainability temp range can hold hands at some point (even if it needs different glass) it's very workable. At any rate, I think this is a cooool idea.

Now, the other possible solution is after my own heart as I do woodburning. My first thought was it'd be wayyyy too hot, like, 900F. Then I realized my units plug into a wall and battery powered would be a whole nuther critter.

This woke up my other brain cell to recall that when I first wanted to woodburn years ago I bought a battery powered ColdHeat soldering iron. Knowing how I drift and can drop things I was going for safety. I pressed the button, put it too the wood and zilch. Nowhere had I seen them say it needed a third contact made of metal (solder) to complete the circuit. Turns out it was even a crummy soldering iron! That'll teach me to listen to info-mercials.

But I am now wondering if the concept may be just what the doctor ordered. It does heat up and go cold on demand as they claim. It uses more than one bat and still isn't much larger than some mods I've seen so it might be a shrinkable device.

Basically, It has a tip like a deer hoof made of graphite-ish material, with a midslot wafer of mica so they don't bump and set off accidentally. The tip is frail but works. So, I'm thinking use metal woodburning tip rods, only somehow split into two pieces, then have a non-heating button (to avoid finger burns) that forces a small metal piece to make the connection.

Anyhow, worth thinking on for the speed of heat and cooling, although without the graphite the time would be less dramatic, I'm sure. The main drawback I see is that the ColdHeat does have a small circuit board built in but maybe y'all can figure out something different to make the idea feasible. The forum Howstuffworks will show y'all the guts of the thing. Perhaps, you may find it of use in some capacity for your modding adventures.

Returning forum to the brains,

He Genie/Xtraelf,
Welcome aboard to the addiction...
My problem with reading the majority of the over 70,000 posts... :-)
Cold Heat gave way to Weller Dual Heat Mod but keep the ideas coming!

I got my camera back, I'll see if I can post some pics tomorrow.

Thanks for the welcome and the link. It's pretty difficult at this late stage of the game to know if something has been touched on before, even tho I try to read at least two complete threads a day. But seeing the Dual Heat was gratifying in that I've never seen one of my kooky, off-the-top-of-my-head ideas working the very next day. GMTA. It really tickled me and more power to him.

I wonder if Google and the search engines of the www weren't so saturated with worthless debris... or say I spoke German, what ideas might I find from modders around the world. Even as I write this I can't help but think there's at least 1 person in every nation at their workbench right now tinkering on their holy grail version of vaping. One (or two) of them will succeed and become rich. But it won't be me. LOL.

I just have a brain that needs a lot of distraction. Last night's insomnia distraction was again about form. Size/weight/shape. If you didn't care about form the problems, though each e-cig section has them, would be easy. Folks will probably always carry cig-form units out in the world but use the "real deal" at home. Unless someone whips the battery issue and other frustration factors ingeniously, public-use units will probably end up closer to cigar size, as that'll be the trade-off for better function.

I foresee that eventually, the end of the line "best" vaporizer probably will be home units that have left the whole cigarette look way behind, be more pipe sized and perhaps resemble an antique torture device in looks. LOL.

Barring a batt breakthrough, there are two design paths. Those who fix the cig looking concept will make a boatload of money and those who perfect the larger hot-rod type could become very comfortable.

When I have time and bucks to mod I'll take the second path for space reasons. I can envision a section that sprayed the liquid in droplets onto Dan's ceramic heat source from an "on-demand" reservoir of liquid for massive vapor at lower temps...

... again for less refilling you could invent something like a 38 revolver where chambers of liquid clicked around the cartomizer and as they turned slots lined up one at a time to give a perfect top off or total refill...

... I even see a day coming where the nic drop is encapsulated in a thin PG cover like a gelcap, and you just pop them in for an analogue's worth of relief...

Anyway, someone in Brussels is screaming Eureka! as I type this.

I'll be offline for a few days but will check back in to see how y'all are progressing soon as I can. These two projects are fascinating.

Day late and a dollar short (but having fun)
