Presenting Tiny!

[mamu]

Presenting... Tiny (lol) ... my smallest vv regulated mod yet.

Features:
-High efficiency 6A, 30W switching converter (OKR-T/6-W12-C)
-Extended atty connector
-Finger adjustable voltage control knob
-juice well
-3.5 - 6 volt vaping range
-Takes 2, 14500 batts
-Totally stealth vapeable

Tiny measures 2-3/4" tall, 1-3/8" wide, and 5/8" deep.

I can't believe I actually squeezed everything in. Not an unch of extra space left.

BIG BIG Kudos to CapeCad and bstedh for sharing the wiring of the OKR module!!

Are you selling these?

Sweeet Wish I could do stuff like that.

 

[mamu]

Thanks guys!

No not selling them at this time - maybe though at a future time.

I want to give a shout out to CapeCAD in taking the time to work with me on wiring pin 1 of this 6A version. You totally rock Cape!!

 

[eyebrook]

Cool nice mod, glad you had help

 

[CapeCAD]

Nice work mamu! I really like the case you used, would you mind sharing where you found that?

Nice work Mamu.

What's the difference with Pin1?

I see is for the 6A

Remote On/Off Control (Note 5) [Standard version]

Positive Logic ON = +1.5 V. to +Vin max. or open pin
OFF = –0.3 to +0.4 V. max. or ground pin

And this for the the 3A.

Remote On/Off Control (Note 5) [Standard version]

Positive Logic ON = +2 V. to +Vin max. or open pin
OFF = –0.3 to +0.4 V. max. or ground pin

Seems whatever works for the 3A should also work just fine for the 6A.


@ CapeCad

What kind of current does this use at rest when wired/fired with Pin 1?

@ CapeCad

@WillyB: the 6 and 10 Amp versions required a lower value resistor than the 3 Amp to pull the pin low since the on value is lower (1.5V/2.0V). This allows using a NO switch with the converter off, then pull high to turn it on.

Current draw is a mere 5mA at rest.

Hmm...

So you are saying it's not about turning on/activating, it's about turning off where that .5V comes into play?

I see for the E version the 3A shows a 100K, which I believe is what you used, while the 6A E shows 49k, but on these an open pin = OFF, the opposite of the standard.

Why not just use a pretty common value of 10k. Wouldn't that fulfill all requirements of both the standards?

TY Cape!

I found the case on ebay.

Here's the white case...
AA white charger

And here's the black case...
AA black charger

Great detective work there Willy

Not knowing there was a difference between the 6A and 3A version, I initially wired with a 100K resister per Cape's schematic and couldn't get the module to shut off. LOL - talk about frustrated and confused!! You see this case I used - no way did I have room for a 3A switch so I totally needed to sink a resister between pin1 and gnd.

Thinking I must have done sumfin wrong, I breadboarded the wiring and took a pic. I showed Cape the pic of the wiring and he saw I was using the 6A version, not the 3A version. Per the E version specs he told me a 47K was needed.

The 47K wouldn't shut the module off either. So I decremented the value til I got to 10K and that was what finally got the module to shut off. YAY!!

I tell ya I was totally doing a happy dance when it finally worked!

Very nice small package VV, impressive. Good work Mamu.

 

[MagnusEunson]

Blimey! I might lose that between two fingers!

Excellent work and collaboration. If you do decide to sell a few, sign me up. -Magnus

 

[hairball]

I really like your mods...especially the one with the carto tank...SNAZZZZY.

Nice work Mamu

Beautiful mod. You still are in the top 5 of the best modders out there. I had to say Best Top 5 so some others and they know who they are do not get insulted lol. so covering my .....
if you decide to ever sell these i would be glad to be put on any list. Thanks for sharing most excellent

 

[asdaq]

Mamu, another great mod and thanks for showing this. It's good to see just how small this can go, that OKR looks mighty inviting because of it's simple circuit.

 

[mamu]

Thanks guys!

Get ready for another...

TY for your kind words Cos. I am proud that I can make a vv regulated mod, but credit really goes to Nuck, bigblue30 and CapeCAD and others sharing what they've done. I am totally in awe of them for figuring out what's what with these modules. They've given me a major crash course in electronics this last year. lol.
