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.
