PTN-Booster Mod in slim aluminium Box with Usb-charger by JJ

[jyjarvi]

hello from JJ´s workshop

Sun is shining and i am sitting inside home and building my new slim aluminium PTN-mod.


Parts i used:
- Aluminium box shortened from 12cm -> 7cm
- PTN04050-Booster circuit
- 2x100uf capasitors
- 8k resistor
- 3k resistor
- 10k finger adjust potentiometer
- Blue voltage display
- 510-connector
- usb-charging circuit
- 5A pushbutton
- battery Samsung 103450 ICP103450s 2000mAh

equipped with Usb-charging so you do not have to open the box.
Battery life is approximately two days or 2x6ml tanks (4-5ml) of eliquid.

Voltage range is 3,7v - 6,2 volts

here is some pictures from assembling the parts, final product and the size comparison:

i was wondering when i would see a cell phone battery in a mod. i have 2 anker 1900s i may try this with.
nice job!

diagram available?

Awesome work!!! I can't wait for modders like you to have more access the Evolv DNA. This thing is awesome as is, but with the DNA in it, it would just be earth-shattering!!!

Hi

I used this diagram https://dl.dropbox.com/u/77813682/PTN04050C_images.jpg_thumb.png

Nice and thin boxmod you have there, great job. JJ, the changes marked in red on the diagram, this is your doing? Also, I'm curious how you arrived at using the 15k and 4.7k resistor values

 

[IronAP]

Where did you find that box?

 

[icanbreatheagain]

my guess on the box, power inverter or maybe a small power supply?

Hi

I found the box and many other mod stuff from Ebay Aluminum Project Box Enclosure Case Electronic 1160 | eBay

Bump, For the curious.

Hi

I did not use 4,7k and 15k resistors insted i used 3k and 8k resistors.With those resistors the voltage range is
about 3,7v - 6,2 volts

Oh sorry, I disregarded the first post and was just looking at the diagram.

But how did you get to those values exactly, did you use a pot and take various measurements? Also it is curious to get the low range of 3.7v when the battery is at 4.2v, especially from a booster. Or is this when the battery is low enough that the 4050 just passes on input voltage?

Alright so here's a SUPER noob question.. How in the world did you take a 3.7v battery and turn it into 6.0v??

Boost circuits draw amps from the source and convert to higher volts than the supply's output. That's why it's neccessary to double-up batts (parallel) or use high-drain batts that have the discharge capability to allow the boost to function.

I have a quick question on the chip you are using. I have been looking into building my first VV mod and trying to settle on a chip to use. I have seen a lot of good things about the OKR series. Does this chip stay cool like the OKR? Would you recommend one over the other, or maybe a different one altogether? I like the idea of a single battery like this over the two batteries for the OKR.

I am learning how to design the circuits I will be using.

###

I like the the input and out put voltage are buffered by capacitors.
What is the range of capacitance that makes sense to use for buffering.
How do I go about figuring something like that out?

###

With adjusting the voltage circuit how do I know, other than trial and error, what resistors to use?

Thank you for posting your circuit.
