Printed DNA30 Bottom Feeder

I don't know what you have going on with the 26650 mod but personally I'd advise to instead design a dual 18650 mod if you're doing something along those lines anyway.

I've played with a lot of different configurations and to me the 26650, while it does package together pretty well with the sx350 and the bottle for BF, it is just more of a waste of space to me. I mean it does add capacity, but from my experience with using it for a while you're only adding maybe 15-20% capacity at most, where a dual 18650 winds up adding like 120% to the battery life and truth is it's really not much bigger than the single 26650

heres a comparison of single 18650 single 26650 and dual 18650's of course that single has no room for the sx350 while the other 2 do, so it looks like more of a difference than usual all else being equal.

to me the future of high power vaping is going to be dual 18650's or a lipo pack, I'm really liking the dual 18650's lately for the sx350. with a single 18650 when you start pushing it towards the upper range of the sx350 power wise the battery doesn't last long at all

Hey turbo, those are some nice looking mods you have there in various bits and pieces, any chance you might post more on these, maybe in their own thread?

the new sx chip takes a 7.4v input and goes up to 100 watts, the chip itself is same size and form factor as the sx350

Are you talking about the sx330 v3?

someday I'll get around to putting up a thread. the dual 18650 one isn't finished yet

 

[turbocad6]

no, there is a new chip. the sx330 is the long thin chip they use in those cheaper box mods, forgot what they are called, but the new chip is different, same form factor same display as the sx350 but 7.4v input 100 watt initial output, probably go up from there with firmware updates, probably go to ~150 watts eventually

All the more so as, one by one, the Sony batteries everyone uses disappear from the market - first their 26650, and not their VTC4 and VTC5 - and we are left with high-quality batteries rated at 20A (LG, Samsung, etc.).

Uh... That was sort of an inside joke. I do not think gdeal is actually working on a 26650 mod.

 

[turbocad6]

crap, then I shouldn't have posted this stuff here I thought you were serious


I deleted the post, sorry bout that

 

[asdaq]

Extra glad I quoted you then, for posterity's sake.

This thread is fairly busy though, and can be hard to keep up with. Eagerly awaiting your thread, turbo. OK guys, lets get back to printing.

 

[Cool_Breeze]

gdeal has mentioned that a charging unit can fit below the bottle.

Has anyone successfully done such an installation? ...pictures to share..?

 

[Rossum]

It will fit, but there's currently no accommodation for it:

It could also be made to fit above the DNA:

...not an easy hack?

 

[Rossum]

Depends what you consider easy. I haven't done it primarily because I don't trust my skills to cut a neat, clean access hole in the shell.

 

[David1975]

I'd also like to see pictures if anyone's done this. I'm still waiting on the parts to be printed, but when I get them, I'm going to be playing around with adding a P-channel MOSFET for reverse protection..... got a few free samples due Tuesday from TI to play with. Would like to know where the best place for the charger is, so I can find a good place for the MOSFET and board

Edit: I might wait for the co-op parts too.... see if I can't build the board for the MOSFET to include the fuses.

While I've not had a GDBF body in hand, there is a technique I have used to create penetrations in plastics that is perhaps a little less hazardous than cutting tools.

I've used an eXacto blade for some work with plastics...not just any eXacto blade and I use them in a manner that may not be endorsed by the manufacturer. I have a blade that is essentially flat and the leading edge (away from the handle) is squared in footprint and has the cutting edge. It can be quite useful when headed with a butane pocket lighter or torch. I also have one that is round, but it's not useful for this application.

A heated edge can be an interesting tool when applied to plastics.

...happen to have a surplus micro USB housing laying around...?

You could cut into the plastic to make a hole for a charger. The challenge will be that the body is round and the face of the charger is flat. So either you are going to have a slight gap in the shell or have the edges of the charger stick out. I could try to design in a charger port above the tact switches, but I am not sure how many people really wanted it. You can do a battery swap in the time it takes to plug both ends of the charger in...It will also be quite a bit of design work, and I have no idea if after you include the required wall thickness that there will be enough space to do all the solders.

Wild! Hydro-dipped?

And I'm sure you're not gonna say nuppin' about that atty.

Nah, just having some fun with swirl painting
