Diy vv bored?

The 8100 is nice but so is the okr-t10, the question is how much do you want to spend? the 8100 build costs a bit more then an okr, as far as performance goes I dont see a difference in either one of them to say one or the other is better.

The okr and 8100 have the same wiring diagram only the chip and caps change other then that pot, resistor, layout are all the same.

If you dont have any mod building experience I would suggest starting with something cheap and working your way up the chain.

 

I am thinking the 8100 I have already found a supplier with them in stock for 16 bucks

 

TI used to give free samples [MENTION=6674]xxDznutzxx[/MENTION] do you know if they still offer this?

 

You know they still might, I havent got any in quite awhile and when I did last time I had to speak with a rep.

 

I think they do, but it depends on the part. Like: Non-Isolated Module - Step-Down (Buck) Module - PTR08100W - TI.com

Also, this site is rather useful, kinda like a "Google Shopping" comparision for geeks: OKR-T/6-W12-C - Murata - OKRT6W12C - datasheet

 

Had no luck on the sample you have to send it from a business email addy so it can't be Gmail or yahoo or anything like that

 

I don't know how many mods you've built but the Nivel may be your best choice, unless you are a crazy high 'extreme' vaper. It's a 3.5A 15W assembly.

It's now a mature design that's had a few minor revisions after been thoroughly tested in the field for a while now. Although a couple $ more than the DNA20 it's much simpler and quicker to pop into your mod.



No shopping for wires, the main wires are already soldered to assembly. Many folks have been having a hard time (read: breaking) with the DNA's separate display which is hanging off a very thin and fragile wire harness, so you have to mount the assembly then figure out how to also mount the display.



And if you've noticed often the display ends up on an angle. Much easier to mount the one-piece Nivel.

You will only need to add one fire button to finish it, which does everything very similar to the Provari. Again a major time saver and it allows for more flexibility in your box design, no more planning or worrying about where and how to mount 2 more buttons.

Almost anyone can be a modder with the Nivel assembly.




No offence, but first off the power requirements aren't all that intense. From the spec sheet.

- Input Current 1.5 Amps (Min) 4.0 Amps (Typical) 7 Amps (Max)

As far as the "panny gcr's", the AW true 1600mAh, IMR18650, has a a Max Discharge Rating of 15C which works out to 24A, that's 240% higher.

I'm getting a pair of these Samsungs to play with.



HID Battery Samsung 20A 18650 20R INR18650 20R 2000mAh 3 6V Li ion Rechargeable | eBay

These are NCA, Lithium Nickel Cobalt Aluminum Oxide chemistry. And have a Max Discharge Rating of 20A, double the Panasonics.



Ignoring the bottom 30A trace, the 2000mAh rating is right on the money falling just a bit at a full 20A continuous drain. Folks should keep in mind that Panasonic uses a 430mA (less than half an amp) load to get their 2250mAh rating.

Samsung cells are used in many high end, high drain cordless tools. It's a lucrative market in which Panasonic seems to have no presence.

 

Thanks for the info I have decided to build 2 separate devices one with the PTR08100W and one with the Vamo pcb atm I am just waiting for the mail man to bring me all the bits

 

not pretty on the inside but it works twin 18650 vamo bored but did not bother with the screen on this one seeing as this one was a learning experience and could not find room to fit it in the box I have but I am happy enough for my first diy vv mod

 

Nice man, you will get cleaner as you go

That pcb is from madvapes? if so it is built with traces in it and you don't need to solder a trace on

Nice man good work

 

Yeah its from madvapes was just not sure if it would take the amps that is the thinking on the trace

 

I am regarding putting the led ware I did lol that thing is bright as hell

 

You can toss a bigger resistor on it and it will dim some if it is a rounded top take a file and make it flat might help some also.

 

Cool I will try that i am still waiting on my other VV bored to get here from China it has not made it to customs yet so it will be another couple weeks I'm guessing but I think I'm going to wait a bit for that build maybe try a straight Five volt or something to get some more practice in and I'm also thinking about putting it in wood might regret that thought but maybe lol me and wood don't seem to get along well lol but I like the idea of wood but if I do make it out of wood it will have to be a at home Vape I work around a lot of water into the wood would not like that much lol

 

When you say other VV board from china do you mean the LM25XX? I am not sure of the model numbers.

 

For the love of Websters...it's BOARD not bored. As in Circuit boards, etc.

Does a tree produce "bored" feet of lumber? No, it does not.

Yes, I know using a mobile can cause auto-correct issues, I assume that is not the case. Humans still get to learn vocabulary on their own, right?

You're a modder now, you can't say things like that mate. ;-)

>.

 

The PTR08100W apparently even though it's coming from "Texas Instruments" and i Live in Texas I cannot find one in the United States so it is having to come from China

 

I will SWAT my phone on the hand and make it right BOARD on its own virtual black Bored 10000 times

As far as me I am a self educated Texan I have been working a 40 hour a week job since the day I turned 15" legal age" to help support my family in rough times
I do the best I can so forgive my errors

 

yes give the guy a breek... or as webster spells it break..lol...
we know what he is meaning when he tipes caff...types..lol...:happy2::happy2::happy2:

 

Ok so I did not like the black paint so after 2 hours of hand sanding this is what I got and the way it will stay

Woow glad that is over
