New RDA Arriving

Status
Not open for further replies.
Pretty stoked about my new rda arriving today! However, I do not have a resistance meter or multi-meter arriving soon. I do have drill bits and 28 ga wire. Can some of you folks with experience give me a simple recipe to follow that would put me in 1.5-1.8 ohm range with 28 ga kanthal? Please list drill bit size and number of wraps with approximate ohm value.

Btw, this will be for a magma clone (infinite) and veritas clone (ehpro). Please, don't knock me for the clones...I'd buy American but money only goes so far and start up cost is high (for me and most folks).

Hi, Michelle.. I'll leave you a link to an awesome tool, how's that?
Steam Engine | free vaping calculators

I will also add that, no matter what recipe you use, i still don't recommend firing an untested build. What mod are you using to fire it?

Not gunna knock you for clones at all.... we use what we can afford to keep us off the coffin nails! :D

*edit to add*
Looks like an 11/10 single coil wrap on a 2mm precision screwdriver with 28g will put you right at 1.7 ohms

Please get an Ohm reader.

For my 1.5 ohm/1x coil Magma set-up, I use a 5/64" drill and make 10 tightly spaced wraps.

I take the said coil and torch it while it is squeezed in a pair of small tweezers.

Install it in the Magma, install onto the ohm reader to verify the resistance.

Install on a mod, pulse and tweak, as required . . . Wick with Japanese cotton pad and vape.

Please get an Ohm reader.

ETA: Use at your own risk. Especially, if you are not equipped to verify the state of your build.

As Kaezziel said, please do not fire an untested build. Maybe a neighbor has something you can use?

Steam Engine is a fantastic tool and usually predicts my builds correctly to 0.01 ohms (and that's likely because no one can build perfect coils.

Most won't knock you for clones, pretty similar devices for 15% the price.

You should use an ohm meter not just to know the resistance of your build but also to check for shorts. If you put your RDA on and the numbers and jumping around on the meter you have a short. In the past I've thought that I had a solid build with no shorts and then put it on the ohm meter only to find out that it was shorting out somewhere. If I would have fired on an unprotected mod it may have not ended up well.

Please get an ohm meter.

To me, that's okay, Eratik... we can give the best advice we have... whether or not the OP has the correct equipment to implement the advice is beyond our control... all we can do is advise and add any caveats with the hope that our advice will be taken in it's entirety :)

Thanks, Kaezziel.

In addition . . . If my atty has been removed from service, prior to replacing it on a mod and vaping, I always put in on an ohm reader to be sure everything is the same. Things can get bumped and loosened . . .Shorts can happen.

Actually, if your resistance is bouncing around on the meter, it is more likely that you have a loose connection.
If you have a short your resistance is going to be dead solid with no bounce (very low reading) and it will read the same as having your leads touching together (reading the internal resistance of the lead wires)

If you are using the little cheapo ohm reader decks that you screw the atty onto, a short should read the same as if you put a small piece of wire across the 510 connection on the reader (this is a good way to check the reader, by the way... short it out with a small piece of non-resistance wire and see what a short reads... go to Radio Shack and pick up a resistor of known resistance... say 10 ohms... short it across the 510 connection and see if the reader shows 10 ohms)
 
Thanks for the advice guys. I appreciate the safety concerns, certainly. My understanding of the factors involved is good and the potential for success high with the nominal information I requested. Getting a resistance checker or multi-meter is high on my list, and I may go pick something up from harbor freight or my local smoke shop tonight; however, I am impatient and want to fire that bad boy up when it gets here. The battery is 3.7v (important) and 1000maH (not important) and will really only be limited by the current drawn (Amps). I know it won't be precise, which is why I requested a range between 1.5-1.8 ohm, but given the other factors should be well within safe usage parameters given the listed information.

PS...I won't blown myself up :)

The above multimeter can be purchased at most auto parts stores or home improvement stores.

In the middle, an in-line 510 voltage meter can be purchased on eBay for about $11.00 with free shipping.

At the bottom, the ohm reader, it can also be purchased on eBay with free shipping.
 
Just a quick update for you folks reading or responding to this thread. I took my RDA with my EVOD battery down to the local B&M smoke shop. The manager is a buddy and vaper. He had the tools and helped me make the coils for my magma and my husband's veritas. My dual coil setup came out to 1.3 ohms. My husband's veritas single coil came out to 1.01 ohms. Both hit really nice. It is such a HUGE upgrade over the EVOD tank. For those who are thinking of upgrading from a cheap starter setup to a $25-$35 tank....get an RDA. It isn't even close in FLAVOR or vapor production. Making a coil isn't really more difficult than changing the coils in a Kanger, Aspire, ect. Just listen to the folks above in this thread...use something to check the ohms.

Yes, folks. An EVOD battery can run a 1 ohm RDA. The math works out to 13.69 watts of power, or between 11-16 watts depending on whether the battery is in need of a recharge or if you just took it off the charger. Of course, you will look like you're holding a metal lollipop...... :facepalm:

Do not put a 1.0 ohm coil on an EVOD or any type of Ego battery. The amp limitation of these batteries is only 2.5 - 3.0 amps and a 1.0 ohm coil will exceed this. Keep your build at 1.5 ohms or higher to be safe.
