View attachment 119515 Three full turns around 3mm double wick., 1.6 Ohm
The service life of the coil - three weeks.
Every day, do a dry ignition.
Hey Chris,
Looking at the resistance of my Kanthal 32 try about 1.1 inches to get just under 1.5 ohms.
This means that the length of the resistance wire between the no resistance silver wire should be approximately 1.1 inches. The amount of coils depends on your wick of course.
Some extra info until you have a multimeter.
Resistance- 13.96 Ohms/Ft
Wire Diameter- .008"
Wire Gauge- 32
So basically that's 1.16 ohms resistance per inch for your wire. Your wire may vary SLIGHTLY but it shouldn't be much.
Hi Shack, no metal flavor. I torch the r wire with a regular cigarette lighter till it glows before wrapping. The torching makes the wire more pliable and easier to wrap and the heating burns away any coating on the wire.Thanks for the info Torq, I don't have a Penelope yet just gathering as much info as possible. I'll be running on a mini provari so whatever it ohms out to I'll just adjust to my sweet spot. On the DID the ohms were jumping all over the place so hopefully I won't get that with this rba. The nice thing about higher ohms I've found is that the battery life is better due to less current being drawn. Also do you experience any metallic taste from the kanthal wire being used? In Scott's review he mentioned a metallic/burnt flavor at first. I've read where some flame the wire before wrapping the coil
Correct, 30ga is tops. Use dead soft for pliability but if you bought semi hard, run a quick flame under the wire and it will soften up25 gauge NR might be a little thick to manage. If you've got the 30, start with that.
Coils look pretty nice
How did you manage to get this pattern?
I got home from a weeklong trip and rebuilt my three Penelopes this morning. I figure there are lots of newbies with Penelopes now that may not have a multimeter or know much about ohms. I thought I would share my favorite coil but expressed in layman's terms.
I used 36ga Kanthal wire and 30 ga dead soft silver wire for NR. 36 is best for HV and 32 is best for LV.
I cut the resistance wire to 1.5" long. I twist the silver wire about 1/4" from each side. This yields a resistance wire with an effective length of 1" with the NR silver on either side. The 1" length gives me 4 nice, lose wraps around the 3mm stock wick. The end result is 3.4-3.7ohms which I find is perfect for my 7.4v vaping.
Hope this helps the newbies. What's your favorite coil set-up?
Just the thread i´ve been looking for
Having my Penelope inc. from Greece, crossed fingers it will arrive one of these days, just wanna get some wire & wick in stock, so i can find the perfect setup from the start off.
Have so many questions I must admit, after reading for the past week or so, hope u can forgive me.
1. NR. Is it possible to use Nickle crome wire for the 2 none resistance wires, everyone only mention silver wire. Been looking on wires.co.uk. Else i just get the 0.2mm Soft Fine Silver Wire - Ref: SI0200-010.
2. AWG / SWG. In this thread everyone mention wire in gauges.
wires.co.uk uses SWG like "0.200mm 36 SWG - 34.4 ohms per metre". And as Torqueguy said, the best for HV are the nr 36. thats where I get confused. 36 SWG would burn ur head clean off, heeh. I would need a conversion table to read AWG numbers compared to SWG. The Conversion table tells me that 36 AWG = 0.1270mm and 36 SWG = 0.193mm. Not sure if Kanthal and Nickle crome have the same resistance tho.
In US they use AWG (American Wire Gauge) & in EU SWG (Imperial Standard Wire Gauge).
3. Wire. Plz clarify and enlighten me gentlemen, I wanna get some wire for both 6,4 volt and 3,7 volt. I will need 3 different types, now that i can use the no resistance wire with both setups. It should make something like 2,8 - 3,2 ohm for 6,4 volt and about 1.5 - 1,7 ohm for 3.7 volt, is that way off?
Hope someone have some experience with that on Penelope. Heard that u need a lower ohm on Penelope than on a regular catomizer / atomizer. And ofc. I can make the coil a little longer / shorter to fit the desired ohms, but only within a certain limit. I have no idea how many cm. an average normal coil are, so kinda hard to predict exactly. Plz guide me so I can get all 3 types of wire home before i recieve my penelope.
My guess with a 4cm coil would be : (keep in mind that i have no idea how long an average coil are.)
0.2mm Soft Fine Silver Wire - Ref: SI0200-010 - No resistance wire
0.132mm 39 SWG - Ref: NC0132-010M - 78.9 ohms per metre - For 6,4 Volt
0.200mm 36 SWG - Ref: NC0200-050 - 34.4 ohms per metre - For 3.7 Volt
4. Wick Can only get my hands on 1mm and 2mm wicks atm, and from what I read on forum, 3mm are the way to go. Atleast for the wick that have to go down the channel´s on each side. Is it possible to use 3x1mm all the way?
Or even 1x2mm + 2x1mm? Just a little worried that it will flod, cause the channels arent closed completely, even tho all setup mentioned are 3mm combinded. Maybe even short circuit cause i cant get 3 wicks to hold the wire, cant see why tho, could just roll em together as one, and they should work as a 3mm. If i can use other setup´s like 2x2mm + 1mm, plz tell me. Sure I read Imeo talking about 3.5mm somewhere, so why not 4mm, haha
Think that´s all I can come up with atm, and I didnt even recieved my awaiting Penelope yet.
I read so many good things about it, just cant wait much longer. Been vaping for 1 year now, its time to leave cartoz in the dust for good. Next big thing must be Proteus, those 2 would make a perfect match.
Hope this will help others aswell - GG4Life
PS. Sry for my bad english, hope u understand anything.
Hi. quik question..im making good coils...1.8ish (i like em) they last for a couple days and then get all gunked up. i see you guys say dry burn to get rid of this. do i just do a series of short burst burns? and itll eventually ash up? is that the concept?
You will want to unscrew the tank portion, then run hot water over your coil for a minute or so. Then with a paper towel tap the coil and wick in the channels gently to remove the excess moisture. Then do your dry burn and blow on the coil as you are doing it until the coil turns red. When you blow on the coil, you are removing the build up as It is burned off. Do this until you do not see anymore vapor. Once you refill, you first couple hits will be muted but will quickly vape like normal
