Need some VV mod help!

[Green Mtn Vpr]

Decided to go to the pros for advice before I hurt an innocent mod!

I am looking to make an existing juice feeder into VV (Boge Revo V2) using the TI switching board. Can I somehow install it fairly simply into the V line into the atty/carto connector (w a pot), tie in the switch, and leave the rest intact for the most part or am I going to have to do a lot of dissecting?

Sorry if I am totally missing the boat... I really have done a bunch of reading on here...too much actually and I am now on overload!

Any guidance, thoughts, diagrams, or appropriate thrashings would be greatly appreciated!

I don't think you'll be able to avoid some amount of disection, but it's likely do-able electrically. I'm not particularly familiar with the Boge Revo V2, but most production devices don't leave much unused space inside the chassis. Getting the additional electronics to fit in there will likely be more of a challenge than wiring it up. To maintain the passthru functionality you would have to use the PTN04050C boost module since you're limited to a single battery. The TI boost module is not a super compact unit like the OKR-T buck module (which you can't use for this). I imagine finding a place to put it will be tricky at best. You may have to add a "hood scoop" for it. With the TI booster, you do have some power limitations, but should be fine over the full range with an SR atty/carto.

The reasons I chose the Revo is there is a good sized open space inside that was for extra carto etc storage so I think space will be ok sacrificing that storage for the extra electronics. As to range, I am cool with the 5.5ish high end...i just want to be able to run from the 3.x range up to/thru PT voltage as I've found diff juices are SO diff at 3.2, or 3.7, or 5@.5a, or 5v@2a, etc so I just want to find the'sweet' spots (not run 6 n 7 volt chimneys!)

Any thoughts on the wiring assuming space is not an issue?

Thanks!

Just looked at a video of it and you might be able to gain the needed space by attacking the spare cartomizer slot if that is not too important to you. Otherwise you may need to to take it apart and look at removing all of the factory circuitry.

What's up with the ionizer? That has me a little confused. Why would you want an air purifier on an ecig??? More stuff to rip out for mod room.

Being the inquisitive type, and having seen how the case clips together, I just had to pull it apart for a look see..
There are 2 boards inside, one for the push button switch and charging circuit, and another for the Ioniser and main power switch. The battery is a small Li-Poly. If one was to remove the Ioniser crap and do away with the main switch, with a little dremeling there is no reason a much larger capacity battery couldn't be fitted. An 18650 is not out of the question and it would certainly make more sense given the size of the juice bottle. There would probably be enough room to fit a variable voltage boost circuit if one so desired.

The ionizer was supposedly scrapped to accomodate the 1400mah batt they come with now... but it looks like there should be enough room using the storage area. Just gotta figure out what needs to be bypassed, removed, or integrated.

Any guidance, thoughts, suggestions...?

Might help if you could post pictures of the V2 (opened up so we can see the internals)......

 

[CraigHB]

Yup, gonna need a good picture. No way to tell without some idea of the internals. If the charging system is isolated, it will be easy. If not, you'll have to put all new electronics in it. Regardless, it's great there's spare room in the enclosure. Haven't seen any makers do that. In that case, it's the ideal device to modify.

should have the unit tomorrow...will open and post some pics. Had some from the forums that I thought I saved, but can't find em and can't relocate online right now! Augghh!

Thanks for the input n interest!

here is the inside

It looks like there may be plenty of room to mod it with the boost chip...If you try to use a "buck/boost" regulator, thats a different animal but could be done...

 

[CraigHB]

Pretty sure the OP wants to retain the passthru charging so the batteries would have to remain as is.

Looks like you might be able to just disconnect the wire going to the center post on the atomizer connector then solder it to the input of the boost module. Run a wire from the output of the boost module to the center post on the connector. Add your caps and adjustment resistors then you're done. Might be that simple. Hopefully the electronics in the Revolution can handle the added current draw of a boost module. They should be able to. Those LiPo batts usually have pretty high drain capacity.

Got it....he will be using boost chip.....batteries in parallel..

Might mention the ground connections needed.....

 

[CraigHB]

Oh yea, have to have some ground connections, took that for granted, oops.

I believe the existing circuit has built in protection that may not allow it to drive a boost circuit as people have reported issues with LR attys. I think it's worth a try.

 

[Green Mtn Vpr]

Thanks Guys...for finding me the pics and the advice!!! Pretty much what I was hoping to hear! I am in fact hoping to retain passthru etc capabilities, so I was really hoping to be able to just mod the TI board into the voltage line to the connector. I will definitely remember to ground it!! ;-O Not too worried about protection as all reports seem to be that LR attys run fine...Ive seen as low as 1.5 regular use reported w/ no probs.

Now I've just gotta find a decent/right pot. or +/- button pot for the V adjustment and re-look up the caps etc I need as my saved 'Mod' file with all my saved pages, pics and schematics is gone!

Now to bug you all just a little more and to make this my perfect mod... I would love to be able to find a small enough Voltage monitor/display to mount in place of the stupid LED light show thing on top (or anywhere else if need be)...but I dont think the voltage displays are 1)small enough or 2)work with the TI switching board??

Any thoughts/suggestions here?



Thanks again!!!

I believe that if you use output capacitors the madvapes type meter will work fine. This is just an assumption on my part. As far as where to put it you would have to play around with the stuff once you have it to see where and if it will fit... I personally have not found a good meter for use smaller than the madvapes one. I am currently thinking about buying an automotive one that plugs into the cig lighter and has an LCD display but the board for it may be too large for practical use...

see this yet?

 

[Green Mtn Vpr]

Nicks...I saw the same? one elsewhere and dont know that I can wedge it in (although it is not as long as the other popular one)...the damn boards make em tough to fit!

I found a TINY single wire lithium cell "gas gauge" chip from TI (BQ2052) that seems to meet all criteria but I cant find a numeric display to wire to it...they even reference its output to one...I just cant find one!! it would be perfect to be able to have a remote display...would make packing in much easier and a small 2 digit display by itself would probably fit right where I want to put it!
