EverCool Variable Voltage Mod

[roadrash]

I have to be very careful what I do now ( See my signature below)..this is one reason I have let you guys keep this thread going.... and I have to say thank you to all of you for helping new people.... I will "step" in if needed...but....I have not needed to because most of you now know as much as I do about the evercool now.

For all you do, This beer is for you Buddy, as you tip toe through this thread. :>)

I'll bet when you first posted your vv-everhot you never thought that it would turn into this.
Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, Sticky, and Sticky

I think the only moderating done in this section of the forum is to look for rules violations. Otherwise, it's their red-haired stepchild.

updates... v2 of my first everCool



I ditched the volt display and also the touch fet. Put in a big 5A switch and a rocker switch to select 2 volt setting that I commonly use. and also 2 510 connectors in parallel just for kicks.

All thanks to bigblue30 and others that helped tremendously along the journey.

Raceengine that's awome! Great build.

Thanks boomer and everyone... I tried with 2 dual coil cartos and it still fires up at 4.3v XD. but I'll probably go with just 2 510 attys... just need to machine a custom dual tip.

Wow.

What is the current rating?

Does it get hot?

 

[raceengine]

hmm... I = V/R
= 4.3/0.8 (0.8 because of the 2x dual coils)
= 5.375 A

Not hot at all. but I haven't tried chain vaping at that configuration. Just that I don't like cartos taste too much so now waiting for my new atties to arrive.

I thought you might know the max current your beautiful DIY VVPV can process w/o over heating.

5 Amps w/o excess heat is impressive.

Perhaps I'll sift through this thread one day.

 

[raceengine]

spec sheet says the ptr08100wvd can handle 10 Amps while the 08060 is the 6 Amps variant if my memory serves me well. So I think it all comes down to your batts. Still don't know why I want to pump 20watt of vape

Because you can... That is the only reason needed. =]

NOOOOOOooooooooooooo!!!!!!!!

Just put together my first vv mods. One is an EverCool and the other using a UCC283-Adj.
Big up to BigBlue and all the other modders contributing freely to this board. Thank you for sharing your knowledge and simple instructions even this monkey could follow.



Trying to talk my elec eng. mate into programming some chips for a PWM mod next.
My poor trusty Riva has been relegated to the bench. This is as addictive.

@ tearocks.... Nicely done!!

Nice.
Is there a schematic available?

 

[tearocks]

Thanks erk and emus.
Haven't got a schematic yet. I was chatting with my workmate about it after reading some of the other threads and he said that would be a good way to go about it. Will post if there's an update.

Working on a new evercool. This time I'm using the Murata OKR-T/6-W12-C since it's a touch shorter then the TI chip and can go to 6v. The pinouts are exactly the same for both chips.
I'm stuck though... Whatever voltage I put in I get back out. So I hook up a 12V PSU and I get 12V back out... not good.
Any ideas?

Did you verify trim pin isn't grounded? Sorry had to ask.

I took a quickie look at this reg and unfortunately the on/off control requires a NC switch just like evercool.

A NO switch will work with a pull down "or was it up" resistor. Check out the Easy OKR-T VV thread for more details.

You may have to play a little with the resistor value to get it correct with the 12A model.

Continuity check everything. I had that problem and it was a short in one of my leads to the POT...
