Say for instance you take two pieces of wire and wrap it five times. You now have roughly the surface area of what wrapping a single wire ten times would give you, but you have roughly half the resistance of what the ten wrap coil would give.

Should be - One quarter the resistance a 10 wrap would give. eg 10 wraps = 1Ω .....5 wrap = .5Ω ....two parallel 5 wraps = .25Ω

 

[Mikhail Naumov]

I thought you were saying if you took a 1 ohm coil and parallel wrapped it it would be .25, this is why I flipped out. That shit blew my mind when I first read it so I acted brashly. When you wrap a coil using two separate wires, the resistance is gauges by one of the wires. So say five wraps, the initial resistance will be that of a spaced 5 wrap coil, but then it is halved since there's an identical wrap next to it. .5 ohm 2.5mm ID 5 wrap 26 gauge coil with another .5 ohm 2.5mm ID spaced 5 wrap 26 gauge coil. Add a second wire, you now have two .5 ohm 2.5mm ID spaced 5 wrap coils, halving the resistance as the electrical path is halved in the circuit, the resistance is now .25ohms.

No different than taking two .5 ohm coils and plugging them into an RDA in a parallel build, it becomes .25ohm. I misread his post, I apologize. I was trying to keep it simple in the guide and overlooked that part.

What? LOL. No. You take two pieces of wire and wrap around a 3mm bit. You now have roughly, as the gaps from the two wires touching the wraps would make it longer, the surface area of ten wraps, but roughly the resistance of one strand wrapped five times. Everything you just said is wrong.

Do you ever UNDERSTAND what you just said? There is no 1 ohm base. Is you had a ten wrap coil that ohm'd out to .1, and you parallel wrapped it the same, you'd have a .55 or so ohm coil. This is lunacy, it is nonsense, and it does not belong in this thread.

You are an idiot misleading people,

You wrap a coil 10 times with a single strand of wire, TEN TIMES. You get ten wraps. You wrap a coil with parallel wires, FIVE times. You now have the surface area of TEN wraps, yet the resistance of roughly five wraps. Please, stop. This is meant to help people, not confuse them with bullshit.

Easy there, I see things in common with this comment

 

[Mikhail Naumov]

FUCK HE WAS RIGHT, I read his comment wrong.

 

[Whiskey]

Thank you

 

[Mikhail Naumov]

I thought he was saying paralleling a 1ohm coil would leaving you with a .25 ohm coil. In my mistake of keeping things layman as possible I made that part TOO layman. I need to revise it, which I will now.

 

[Iliketurtles]

to work out as roughly half the parallel wraps would both have to be as long as the original 10 wrap, its no big deal.

Mikhail - it's still a kick ass guide

 

[Mikhail Naumov]

I revised the guide, like I said, me trying to keep it overly simple and layman made me forget to get advanced when I needed to.

Revision:

There's also paralleling wire. Which is when you take multiple strands of wire, put them together and then wrap your coil. Say for instance you take two pieces of wire and wrap it five times. You now have roughly the surface area a SLIGHT bit over what wrapping a single wire ten times would give you, but you have roughly half the resistance of what a single wire five wrap coil would give you. This is used to obtain a lower resistance than you would when using single wire builds is yielding a resistance higher than what you want. The length of each wrap in the parallel coil is going to be longer than if you just tried to wrap one wire five times. So, you're now wrapping two wires five times. This result is, the surface width of a ten wrap coil, but you're getting the resistance of a wire wrap spaced coil, only halved, because there is a second wire.

Please check your math. If one ten wrap coil equals 1 ohm, and you add another 10 wrap coil in parallel with it, you now have a total resistance of .5 ohms. If you now make those ten wrap coils into five wrap coils, you have cut your resistance in half again, or approximately .25 ohms.
Mr Turtle is correct. How you mount the coils does not make a difference. Wrapping two wires next to each other does not make a significant difference in resistance, as compared with two separate coils mounted opposite each other, as done with many three post style atomizers.

Maybe we are not understanding what you are trying to say.

 

[Mikhail Naumov]

You are way too late to the party here buddy. Also, I'm talking about WRAPPING parallel coils, not parallel coil setups in the RDA itself (i.e. multiple coils all connected to the positive post, splitting the load)

Sorry. Got distracted and should have refreshed my feed.

I thought he was saying taking a 1 ohm coil and paralleling it would make it a .25 ohm coil (English isn't my first language, I'm both a suboxone and xanax patient on other prescriptions and I just woke up meaning my brain just got bombed with medication and I was just confused)

He's right, I was trying to be as simple as I could in that guide because I wrote it thinking the people reading it would have NO idea what any of it meant. When you parallel a coil, you're not halving the resistance of a ten wrap coil if you parallel wrap to get a 10 wrap surface area coil using five wraps. The primary resistance comes from the five wraps in the parallel coil, which are then split in a parallel circuit giving double the electrical path on the same coil, thus halving the resistance.

Ten wrap parallel coil has the resistance of a five wrap single strand coil, WHICH is then split in half from the coil having two electric pathways (two wires). I'm a bit embarassed as an electrical engineer for this fuck up, but it was because in my attempt to simplify everything, I simplified that to the point where it wasn't correct. I'm glad he pointed it out, very glad. Thanks turtleman.

Peer review is important on something like this.

 

[Iliketurtles]

It is a nice guide @Mikhail Naumov you are welcome.

 

[Mikhail Naumov]

Feel free to review it all and point out anything. Just because I'm an electrical engineer doesn't mean I'm infallible or that I don't make accidental mistakes. I type at around 180WPM and I'm not fond on proof-reading my shit, that guide has already been edited 12 times. I'm a human being too.

The reason I flipped on turleman is because I power read his post and thought "THIS DUDE THINKS PARALLELING A 1 OHM COIL GIVES .25? WOTM8?) when that wasn't the case at all.

 

[rolf 2]

mikehail
just got the pwm module . thanks for the link.
in their scematic they left out the value of the pot ..is it 10 k ?
laying up some fiberglass for the battery holder now.
does a dc voltmeter on the output read the effective output voltage reasonable well ?at least to be a good guide .?
thanks.

 

[Mikhail Naumov]

Depends entirely on where the outputer meter is wired. If wired to the 510 +/-, it will give current output voltage, if wired to the battery + and - it will give current cell charge, etc.

jes i'll wire a three way switch if i find room for it . one side will read the battery voltage volts dc . which the voltmeter module is designed for .
the output at the 510 is not dc so . the way i see it is it pulses the full battery voltage in my case is 8.4 volts..x amount per second
so if the duty cycle is set to lets say 50% it should read about 4 volts . the question is a rms voltmeter not nessesary ?
is the adjustment pot 10 k ...if you remember ?

 

[Mikhail Naumov]

Rolf I am having a very hard understanding your question.

The output at the 510 is definitely DC, the entire workings of the mod are DC. Vaping is not a technology that uses AC. There are volt meters you can wire in yourself.

WHAT DO YOU WANT YOUR VOLT METER TO TELL YOU?


Final output voltage?

Input voltage?

Amperage/Volts under load?

Voltage under load?

Etc


Is English your first language? Because if not I'm multilingual and could help you if you're having problems communicating your problems through English.

no english is my second language . i was born in germany .
want to know the remainig battery voltage ...one side of switch
other side of switch i want to mesure the final output at the 510 .
which is pulsed dc . and just wondered if the volt meter module will average the pulsed voltage halv decent .

 

[Mikhail Naumov]

I speak decent German, type your question out in German.

 

[Mikhail Naumov]

I'm just going to use the BM diagram because, I'm still not 100% on what you're trying to do. If you're trying to SPLIT, a meter's readings via a switch, this is how on a PWM or any reg mod.

Thank you Relayer1974 for making this so I don't have to bust out my MSPaint abomination diagrams.

You can find the switch you need here. http://www.digikey.com/product-detail/en/apem-inc/GH39P010001/679-1882-ND/1796285

 

[sychosis]

Any way there is a link differant from the op , it shows unsupported for me . If not I will bust out my laptop to check it .

hi mikhail thanks for that .. thats what i used in other mods t10 and t20 . but i have dpdt and have some more in my junk box . so no problem using them.
just extra contacts. so does the pulsed dc confuse the meter ?if so would a capacitor across help ?

Pastebin when I posted it shows the FULL guide with a scroll bar already on the forum, so if you aren't seeing it, or just as a link, there could be a bigger issue. Try copy and pasting that link, if it's a no go, let me know and I'll send you a notepad file or something.

No the pulsing doesn't do that, you'll still see the maximum output voltage the second you hit the button, though it will flash. Unless you're using a camera with an extremely high refresh rate to film it you'll be fine. There's no need to wire up a capacitor to (I assuming this is what you would want to do) store the voltage long enough for it to register.

 

[Mikhail Naumov]

I just revised it the final time, it was mostly spell checks and stuff. If the mods want to sticky it, it's ready. If not, I still got links on standby for l3 newbs.
