Istick dripper coil resistance problem

[Yiannaki]

@shaunnadan

I just had a brain wave. Lol

Once you get the 30g wire. Build the dual coil with a "sleeper build" I.E dual coils made with a single strand of wire.

By doing so you'll:

- Have a higher resistance than you would if the dual coils were individual strands

- Lower the ramp up time before they start glowing


See this link on how to wrap as I have mentioned. He uses 24g in the video but obviously it can be applied to any wire.



Good luck and keep us posted

It's so awkward that rip hasn't corrected his mistake yet. A sleeper build is not what he said it is. It is wire spaced out. (Not touching). One strand of wire is a continuous build

I built my brother a 1.1 ohm coil with 26g on a Stillare and it was awesome at 20w.

How many wraps would I need using 28g and 30g for the sleeper build?

Note the heatflux and how low the wattage is. this will give a cool vape with plenty of up and down so if the coils take to long to warm up you can push the wattage up a few clicks. I left the leg length at 5mm as I don't know if you center coils or leave them offset.

Same build but on dual coil. Note what the heat flux is now. I would much rather do the single coil build for what you are chassing

How many wraps would I need using 28g and 30g for the sleeper build?

I would say about 9 per coil. Start there and see what result you get

Tried the sleeper coil build now with the 28. Did 11 wraps on a 3mm diameter. Got 1.1ohm.

Ramp time was much better but overall not the best performance. Will try and get some 30 today and rebuild.

Merry Christmas

So I went out and got myself the eleaf alpha. Very similar to the lemo drop.

Made myself a single coil at 1ohm using 28. Ramp time much better and zero leaks.

It's got a decent amount of Vape. Excellent flavour and decent size.

My only things is that i have to use it at 20w for good performance. Any ideas on how to get bigger clouds apart from changing to 30 wire for now

What juice are you using?

On a single coil set up maybe try a higher resistance coil using the 28g wire. 1,2 ohm gives you a wider range of power settings, your ramp up time will still be quick I think and a bigger surface area helps with vapour production.

 

[shaunnadan]

I've tried with a 50/50 juice and also a 60/40 blend which is a bit better.

Will try a 1.2ohm coil tomorrow and see the results .

1.2-1.4 ohm single coil with 28AWG works best in my testing with the iStick... Dualies are just too much metal for it to heat up quickly.

yip found the same thing with my brother in laws VAMO this afternoon. I got him a tugboat for Christmas and a duel coil setup on 1.2 ohm was to much for the VAMO to cope with. did a single 1.2 and the VAMO started chucking the vapor.
