Good morning shiners! @Ricky Vapes batteries are marked 3.7V as that's the nominal, or average voltage theyll deliver. However, a Li battery like we use, 18650, 21700 and the others all charge to 4.2V when freshly charged. With a mech you always calculate the maximum draw on a battery to determine what you can safely run without getting your batteries all toasty. So Ohm's law calculations should use 4.2V as that is the highest draw/stress on your single 21000/18650/whatever battery.

I thought it would be 180 watts? 24 amps well within my batteries cdr limit of 35 amps.

3.7 times 2 is 7.4 volts.

I thought 4.2 volts was just the amount the battery holds. The battery discharges 3.7 volts down until it reaches a certain point from my understanding.
I build using 4.2V in my calculations to be on the safe side. Series mechs have the power to run some massive coils. I think you would get better vapor production by building higher resistance coils with more surface area.

These are the batteries I have.

Samsung 30T 21700 35A Flat Top 3000mAh Battery - Genuine

So if I build 28 gauge kanthal at 3.5 mm ID 8 wraps x2 coils that should get me 1 ohm.

Plug that into the ohms calculator and this is the result.

Am I doing this right?

Yes your calculations are correct. I don't know about 28ga. Wire on that mod though. It may get really hot and would be fragile. I have seen a lot of people building 24 ga 16 wrap coils and such on those.
Edit: you could probably bump it up to 4mm ID on it which would raise the resistance a bit and allow more wicking material to fit...

Good morning Shiny's
I've tried and enjoyed many teas, both loose leaf and bagged. Always find my way back to Twinnings lady grey and irish breakfast. I do occasionally add some dried jasmine blossoms to the lady grey.

I like Early and Lady. This time, I got some Stash Chai and I’m trying Harney & Sons India black. Darjeeling is another good one, and you’d think it would be easy to find, but since the Kuerig plague started, coffee/tea aisles have been taken over by those horrible little cups. Tea is an endangered species at the B&Ms. The loose leaf is entirely gone, and even the bagged stuff, there’s not half as much as there used to be.

That sounds like a ginormous coil. But I’ve gotten so used to Clapton wire, I haven used any round in a year.

I can grab a spool of that, should I get 26 too? Any others?


And thank you, for always helping me out.

Well I'm English so a cup of good old robust breakfast tea is essential. Forgive my ignorance but what is keurig disease?

A very good friend of mine has an Indian wife and she owns a tea estate in Assam. They give us several months supply each year and it's known as the champagne of teas. It mostly stays in India. It's very strong and delicate at the same time.

Love a cup of Earl Grey in the afternoon too. Happy tea drinking... All this talk of tea is making me really want one :D

It would end up close to the same size as a 5 wrap triple core clapton coil or just a bit bigger. It will have higher resistance than the claptons because it is made of a single wire. I have trouble counting wraps on those types of coils but taking a picture so I can enlarge to count helps. 24 and 26ga. Are my go to single core wires. I would pick up a spool of each for your stash.
You're welcome. Anytime.
Edit: I like 20 and 22ga. But you may find the resistance too low for your taste.

I’m a fan of 26G. I can make most simple round coils out of it and get a resistance about what I want in a reasonable number of wraps. 24G is also nice. I never use 28G anymore except for maybe a Clapton or fused Clapton for the core.

I used to like 28G for mtl builds. I wouldn’t use that on a series mech either. You’re hitting it with a lot of power. Bigger beefier could work best that work out 0.6-0.5 ohm as @Skunk! pointed out. With the Unicorn on top beefier coils will work far better than small 28G coil builds.

Locally it costs about $350 to spay a female dog. I don’t know how much a neutering is, as all my males were already neutered. The vast majority of dogs in my nearest shelter are not fixed, and have never had any sort of vet care. Out in the country, people just get a dog and give it food.

They come in with heart worm flea and tick infestations, with birth defects left untreated, with injuries resulting from being hit by a car or attacked by some other animal. Relatively few are found in a healthy state - so few, that if a dog is found without fleas, it is not put up for adoption as they’re certain it belongs to someone and they attempt to find its owner.

It’s safe to say that none of these local dogs costs the shelter less than several hundred dollars to get them healthy enough to adopt out.

And dogs who have already had these set backs are more likely to have future health issues.

The problem is, these shelters already rely heavily on donations just to keep the lights on. And there are still plenty of kill shelters to euthanize the over flow.

Fortunately there are also plenty of people who adopt.

The shelters can find homes for most of these dogs, so it’s not as if it’s a choice between a poor family and death.

But sending a dog they’ve investing hundreds of dollars in to a place where their health will be too expensive to maintain means that, one flat tire later, that dog is coming back and will again cost a lot of money. Recidivism is a heavy burden for them to bear.

If a person who is too broke to pay an adoption fee is adamant about getting a pet, they could probably find one elsewhere, either a stray or some owner who has no choice but to give up their pet. Rescue one from the street, so to speak. But they need to understand the burden rescues are under.

My other POV regarding the family in town... my advice to her had nothing to do with the above comment. All I could think was, if the poop hits the fan, and you have to give up that dog, how would that affect your child, who has already had such a hard way to go? The thought of that breaks my heart.
Reading your reply makes me very sad as I know there are rural places where this is the case but I guess I have forgotten. I am in a very rural place but about ten years ago a friend of mine and myself, started a group "No Kill Paulding" (name of our county is Paulding) we attended every monthly commissioner's meeting and spoke about the atrocity of space killing of shelter pets. We raised money and bought air time at the local station and got the community involved. We rallied. The group grew, we all showed up at commissioners meeting wearing red. We demanded change. We educated the public about the waste of their tax dollars in euthanasia. We have several great Rescues nearby and they helped us. One PitBull rescue raised 80K and donated it to a local spay and neuter clinic who was already giving great prices. The money keeps coming in, it is always given to the local clinic fr low cost spay and neuter for ferals and dogs/cats gotten at the shelter. Meaning we can get all a dog or cat needs, spay, vaccines and heartworm or Feline Leuk tests for less then $100. The commissioners finally listened and changed some ordinances allowing ferals to be left alone in their habitat so no more were being taken to the shelter and euthanized. They also hired an adoption coordinator at the shelter. We are now very proud of our 97% save rate. It takes a village. I am a volunteer and I allow them to send me out to trap ferals. I also foster kittens and take them to and from the clinic for spay neuter and vaccines. I basically get them ready to hand over to the rescues we have set up to adopt out. To learnt to do all of this we followed (to the T) Nathan Winigrads 12 steps to shelter reform. It worked.

IDK, but I think it's important to match the pet to the owner/person. I personally would not want to see a larger dog like an adult Shepard or Doberman go to a family which has never had a dog before, have no clue on training, and live in a 2 BR apartment with two small children. That's a recipe for a dog turning to the shelter/rescue. Cats are easier, and you can transition a cat from an outdoor cat to an indoor cat pretty well, and not worry about past pet experience, unless it was really bad, like returning pets to shelters after a week when they don't work out. It has to be the right pet for the right home.

As for a financial test, I would prefer a home that understands that things like medical issues may occur, are they aware of their responsibilities as pet owners, and feel prepared to do so. Folks can be great owners even if they may run into problems with a large unexpected vet bill. It's more about a stable environment for the pet and the willingness of the new owner to supply that.
that is very important and you would be amazed at the stupid choices people make when picking out a dog. MOstly based on looks or what they had as a kid

Kuwrig is a coffee maker company. Their machines make one cup of coffee using a pod, rather like a coffee Juul. It’s a great concept for some people... I got one for my mom for ease of use, and it turned itself off, so I did not have to turn around and go back to get apartment to check if it was off every time I took her out, lol. But it tastes terrible and the K cups are stupid expensive.

I normally drink tea in the afternoon, as an American, I need coffee in the morning. Lots of really strong coffee.

Lucas county dog warden started a project a few years ago where hard-to-adopt dogs were sent to local prisons and inmates trained them. They had great success getting those dogs regimes. Don’t know if they’re still doing that or not.

Problem lately is irresponsible owners. Whatever the popular breed is, too many people get the idea they’re going to make money at it, whether they know the first thing about breeding or not.

And too many are still not spaying/neutering, so there are loads of unplanned litters.

I spoke to a volunteer at one shelter who said they get at least six whole litters a week, double that in the spring.

The local Facebook group has several new pups for sale posts every day.

We just have dogs coming out of our ears.

There is one vet that I know of that does low cost spay/neuter for pit bulls once a year, because that’s the dog of the day in these parts. A good half of the dogs in the closest shelter are pits. And yet you still hear of people intentionally breeding them. They think they’re going to make money, and end up selling 2-3 of a litter because you can adopt them for almost nothing. So all those pups, at 3-4 months when the owner realizes they won’t sell and are not willing to feed them, and not allowed to have so many dogs without a kennel license, go to the pound.

It’s just never ending.

None of the local counties even have a budget to deal with cats. No TNR, no nothing. I personally think that’s why the coyote population has exploded, people leaving cats loose. Easy pickins, especially all those unwanted litters. At least if a dog is stray, the warden will pick it up. But we’re lousy with cats. I see more cat roadkills than almost all the other animals combined. And I’m not crazy about them, but that is just so sad.

I got some 24 gauge kanthal wire I could use . I’m usually using 26 gauge nichrome wire and getting it to 0.11 ohms. I might try doing a bunch of wraps to get to a higher ohm with that if I don’t like the kanthal. But it makes sense that a beefier wire would be much better with a series build

@Ricky Vapes, they're LiFePO4 cells that you have.

No. Lithium cells are generally marked with their nominal voltage.
Most standard lithium cells have a max charge of 4.2v and are nominally rated as 3.6/3.7v. LiFePO4 chemistry cells have a maximum charge of 3.6v and a nominal rating of 3.2/3.3v.

Good morning shinies! I feel less like the hand of death is hovering over me, LOL. Trying to wake up for notes I SHOULD do, operative word SHOULD.

Oh I probably will but I am waking up.

Also, I won the Innoken Flashlight vape givaway (I think I made Innoken Paul laugh) because I have night blindness and I DROOLED. I am excited for this one it really is a SMART idea.

Hope your days are shiny. I might buy nic, since it appears I am going to live. LOL.
