Don't want to blowy myself up

[ouzel]

Hello everyone,

here's my question: i'm not trying to get all fancy, make huge amounts of vapor, etc. i just don't want to blow myself up. So i saw rip trippers video on rebuilding aspire bdc coils and it seems simple enough. i only use bdc coils so i thought i'd try my hand at it. the problem is i don't have one of those fancy thingamajigs to test the resistance. on his video he wrapped the wire 5 times and he got 1.4ohm resistance. so if i do exactly what he does but wrap it six times or even seven (to be on the safe side) i should be fine with that correct? my battery is just a run of the mill spinner 650mah that i keep at about 3.7v - anything higher than that usually tastes weird to me.

before i tried messing with any of this i read up quite a bit and ran into something about sub-ohm vaping and i just want to make sure i don't run the risk of blowing my self to kingdom come.

like i said, don't want to get all fancy, just thought it would be more cost effective to replace coil myself. (or run the risk of running out of coils and having to either pay six dollars for a single coil head at a local b&m or wait for days while i order new ones)
thanks for any help in advance!

edit: current coils are 1.8 ohm

You need a testing thingamajig (AKA multimeter) before building your own. Also, you need to stay at higher ohms with an eGo battery.

Do you know what gauge wire rip was using? If not than you can't know if you will come even close to the resistance he got. You need a multimeter. It's a must have when building your own coils.

yes he was using 32g wire and 3mm wick but suggested using 2mm wick (he didn't have any at the time)

i just thought i'd be safe so long as i didn't try to do anything like that sub-ohm stuff... i know the more length the higher the resistance so i figured more wraps=more resistance but i guess i better get that meter thingamajig to be on the safe side

You'll probably be fine if you follow what rip used and go an extra wrap or so but don't blame me if you blow yourself up. You really, really need a multimeter. You can pick one up locally at any hardware store and they don't cost that much for our uses.

no won't blame you and also, like i said, not trying to be fancy or do something stupid and give vaping a bad name ... so you can buy a multimeter at the hardware store? that you can use for these purposes? i saw only one on one of the places i usually get my hardware from and it was pretty expensive. i thought you had to buy one especially made for pv's.
can i bother you for a link? to a hardware store with a pic of one? so i know what to look for when i go get one? or just the name of one and i can look it up myself?

A multimeter isn't just to check the resistance, although that IS important. It will also tell you if you've got a short anywhere, like if your coil is touching metal when it shouldn't be. If you short out an ego battery, it will likely kill the battery, but could lead to venting. This is actually true of factory built coils as well, I had a bad protank head, fresh from packaging, short out and kill an ego battery.

They make meters that you can screw an atomizer onto, specific for vaping, these are handy. You can also use a digital multimeter that can be found at just about any hardware store, and it will actually do more for you. If you're using ego batteries, you'll mostly just be checking for resistance on your atomizer heads, just be sure to use the correct setting and adjust for the internal resistance of the meter. If you get into APV's with replaceable batteries, you can use the meter to check the voltage on your batteries.

I use this one: http://www.harborfreight.com/7-function-digital-multimeter-92020.html

It's not the best, but it works, I just have to constantly recalculate the internal resistance as it seems to fluctuate.

that's the one i saw on the site i usually get batteries, tanks, etc from and it was pretty expensive, something like 70 or 80 bucks. for that i can just buy a two year supply of coil heads and be done with it.
thank you for the link i will definitely go buy one (or one like it) at the home depot before i mess around and end up like one of those daffy duck cartoons, holding onto my charred ego battery before crumbling into a small pile of ash

Here. This is reasonably priced. 510 Ohm Reader - AltSmoke I have a VAMo, so I can always get a reading without one. I bought two multimeters, and either they didn't work, or I couldn't figure heads nor tails out of them. I wouldn't try rebuilding without something to measure Ω. Seems rather dangerous. Actually, I wouldn't try rebuilding unless I had something beyond an eGo.

thanks everyone for your answers.
Lessifer, i found a fairly inexpensive ohm meter online (20 bucks) - one of those you just screw your atty on, i think i'll get one of those because i also realized it's a double coil and after reading about that for a while, it seems pretty complicated with the probes and blah blah. this way, i'll be safe from shorts and know the resistance without any guess work.

thanks again everyone!

ah thank you, even more inexpensive.

i've ordered the wire and the wick (a couple of days ago) but i'd already ordered a good supply of coil heads as well, those will last me for a while while i continue to read up on all of this.
now i will not rebuild the coils until i get one of these meter thingies. safe from shorts and also know what the resistance is. better safe than blown up.

thanks all, again

and thanks Meniere for the link

This one is like the one I have. To calibrate it, set it to ohms, touch the leads together and jot down or remember the reading. You will need to subtract that reading from the reading you get every time you check an atty resistance.

You can get a decent multimeter locally for under $12. I think mine was $6 - $8 at my local hardware store. When I touch the leads together I get .5 ohms so I have to subtract that from the measurement of my atty. Since I'm not so good at math I have one of those little box ohm meters but you still should have a multimeter if you don't have a VV mod to check battery voltage. If you have a digital VV mod you can use that to check resistance and voltage.

This is what I have and I couldn't live without it.
