A 5/6 wrap 1.2mm ID .8 ohm tight cotton wick is my go to.
With the smaller ID heat up time is not even noticeable.
Of course I am using a suped up Reo with AW 1600mah 18650's so voltage drop is minimal.
(.16V drop with 4.2V battery IIRC)
End up changing out the battery after about 2-1/2 to 3 mil of juice but voltage at the RM2 posts is still about equivalent to what a semi fresh battery will supply in a stock Grand and more than an 18350 mod
BTW even if you don't go south of .6 ohms, length of time before feeling the need to change the battery is a great advantage to the fuse & brass firing pin.

Yeah, I forgot about your tiny jigger-doodle. Definitely, smaller ID would do a lot for heat up time.

My rule of thumb with MM wire set-ups is that I look for at least 3+ amps being delivered for the duration of a useful battery charge. I do the wire calcs based upon what I expect the tail end of the batteries voltage curve will be at under load. No lag, zero wait, pure smoothness. oh yea and taste.

But the quick formula for an average mech is just do a .8ohm or .7ohm coil and you are go to go. IMO

Same; but 7A :toast:

Finally I can check out some of the setups that a mech won't allow.

20A capable VV from 0.6V to 5V Reo Grand! :banana:

Built for experimenting with an idea I have for a low voltage atomizer, but going to have fun with it for now.

(Yea I know I will have to stay within 45W to limit battery current to 6A)

BTW, first vape on your own designed mod is something that can't be beat.

Will put together a thread in Reoville about it later.

Have to go to bed now.

awesome. why are there 2 pots?? not sure about the particular board you're using but I know the dna at least is very sensitive to getting any juice on it, might want to think about some sort of protection from liquids,

and yeah gotta love the first firing and getting a great vape on a custom built mod :)

love the rat fink, hot rod reo :)

I still don't get what you have in mind for a low voltage atty, I'm picturing something like that to need much higher gage wire to equal the performance no? do you have something in mind other than a conventional coil? (somehow I'm betting you do :) )

I've been waiting 5 days for my ribbon to arrive this afternoon. I spent 3 hours playing around with it, trying to learn how to twist it and struggling (failing) to try to take decent pictures...

...Just so I can show up late to the party (per usual) and watch everyone roll their eyes as I interrupt the thread that just had a potentially bomb dropping cliff hanger with my "here is my not new efforts, not new thoughts and crappy pictures. What do you guys think?"

Anyway, here is what I did tonight...

My first attempt was a total failure. I started with 4 feet of wire. The first twist went really well but the tripling up reverse twist was a mess. I had trouble getting it chucked up and then I had trouble counter weighting it so I tried twisting it back on itself by hand. I failed. Judging by the pictures earlier in this thread of what this stuff should look like I ended up with about 4" of usable wire. That is what I used for the set up above.

My second attempt was 6 feet of wire to start with. First twist went just fine. Triple back went better. I got it chucked up and spun it backwards. I think I stopped too soon. I finished it by hand. It's going to take some practice to get this looking like the pictures of what it is supposed to look like I think.

On a remotely related topic, I'm getting excellent results with microcoils made of tightly twisted Kanthal 30g (2 wires).

Mellower vape than single K 28g, longer duration, reasonable heating up time. I call it the poor man's Mundy's Magic Wire :p

I know, I know, pics or it didn't happen.. Working on that :)

My favorite wire remains triple twisted Kanthal 32ga. It's very easy to make and work with, still reasonably thin, makes great 1-ohm coils that fit most devices, decent heating time and great vapor. Almost as good as the MM for flavor, but it does heat slower.

1 pot is 100K and the other is 5k and a 2.7K resistor all in series.
2.7K limits it to 5V. (Although I am rethinking that but it is buried below the board)
100K was too finicky in higher voltage range so I crank it closed and use the 5K for normal voltages above about 2.25V.

Board is GE UVT020A0X3-SRZ http://www.lineagepower.com/oem/pdf/UVT020A0X.pdf

Yea, once I see how heat dissipation goes and make sure I have it the way I want I am going to encapsulate the board.

Keeping the atty idea under wraps for now, it is completely out of the box.

The triple backwards twist is simple enough to do by hand without the counter weight for short pieces.
I am not sure but you might have went to far on the triple twist?
I am out right now except for a couple coils worth, but if you drop me a PM with your address I will send you a piece for comparison next time I make some up.

Big question is how does it vape for you?

:vapor:

Twisted round wire working so good compared to 1 wire of equivalent cross section is what lead me to play with twisting ribbon.

Next to decide whether to cut a rectangular hole below the button above the bottle for a .28 voltage display.
That is the only place I can see it could fit and it will only fit there due to the thickness of the aluminum taking some of the display depth.
Anyone found a really small voltage display like the DNA display only a stand alone voltage display?

Also to mill the catch cup down, but I don't have a mill!

Lunch is over now so got to go back to work.

I think I did go to far when I twisted it together. I didn't go far enough with the drill so I grabbed the ends and started twisting. The second piece turned out better than the first. I think it will just be a matter of doing a few more and getting the feel for it.

As for how it vapes...
I am pleasantly surprised. The coil measured out to .6 ohms, maybe a little more but my meter only goes to the tenths. It vapes very nice. The vapor is warm and "moist". Moist is the word that keeps popping in my head when I try to describe the mouth feel. That and the word "round" comes to mind when I think about the flavor. I am definitely enjoying it. I'm going to give it a few more days and report back after I get to know this coil a little better.

I'm finding it easiest to start with single lengths of about 2 - 2 1/2 feet. Six feet, especially the first time, seems hard to control.

So, I do the initial twist on 3 individual pcs that are, say 2 1/2 feet long. I get ~ 16-18" from it. Enough to re-coil most of my atties, or send a decent starter to someone.
