Varicool Dynamite-mod with 10Amp limit

[jyjarvi]

Hi

My new Varicool Dynamite mod is ready to tease genesis atomizers
with 30+ Watts of power. The mod works fine with 0,3 ohm to 2,8 ohm setups

There is a 10Amp limit in the mod and 2x18650 Samsung CGR 2800mah batteries,voltage range is 3-6 volts and the mods height is 9cm.

I really like the look setting the electronics aside alone. What is it made out of?

Varicool

Varicool mod is based on PTR08100WVD circuit wich have 10Amp limit and efficiency 96% i tested mod with RSST-atomizer with 6 volts to
0,8 ohm setup ---->45 watts

Parts:
- PTR08100WVD circuit
- 2x100 uf capasitors
- 220 ohm resistor
- 200 ohm potentiometer
- 5 amps pushbutton
- 510-connector
- voltage display
- piece of soldering board
- 2x 18650 samsung CGR 28C 2800mah batteries

Nicely done, looks great

Hmm.. Don't these modules have an inhibit/enable line which can be used with a tac-switch?

(And where did the display tie-in, on the schematic?)

sure looks nice !! thanks for the wiring diagram , easy to follow.

To the same places as the atty base.

OK, cool - the meter solved!

What about the enable/inhibit and a tactile? (I've had miserable luck with big, high-amp buttons - and the price on anti-vandal buttons is completely mad)

Pin 1 appears to be an inhibit control. Ground out to turn off, I think.

EDIT: Interesting that the rated output is 5.5v at the top end but it's getting 6v.

 

[breaktru]

Yes Pin 1 is the inhibit pin and a N.C. push button (tact) to gnd can be used to turn on the converter when the P.B. is pressed causing the gnd to pin 1 open.
I personally never use the inhibit pin. I prefer applying voltage to the converter only when needed via a N.O. 3amp P.B. Use of the inhibit pin will trickle down battery life.
That is my preference and I am not condemning those who go the inhibit pin route.

1mA standby current is hardly much price for the benefits of using the inhibitor pin. Given the capabilities of the regulator vs the buttons usually used in these mods, it seems pointless to use this regulator if you are not going to use the inhibit pin.

One could always put a main shutoff switch or remove batteries to stop this standby drain.

Then I must be an idiot>>

 

[Innocuous]

I have no problem understanding folks using a Master on/off and fat buttons, I just thought I had read it was included.

Normally-open, hmm? Dratted work arounds - I seem to recall a resistor and a jumper to a NC tact for the OKR mod.

Well, it's still lovely and the schematic and replies are greatly appreciated!

Are you getting anything by using it vs, say, a 3-5A regulator?

 

[Innocuous]

Of course. he gets PWM, long battery-life, and simplicity.

Also obviates a master switch.

You get all that with a 3-5A regulator, I don't see your point.

 

[breaktru]

which 3-5A regulator are you talking about?

 

[dr g]

Edit: Nevermind, I thought that was a 3A 12V switch but I see it is 3A 28V.

Still, this particular horn button could potentially be overpowered depending on how far the batteries were run down.

Another benefit of ignoring pin 1 is that the build is simpler and can be smaller that way. This is how I like to use these also, and I even forego the vv by using a fixed resistor for an even smaller build.

I'd say the real reason to use these are for the step down efficiency and ample power.
