My (very basic) 510 juicebox

[highping]

I have had this mod in my head since the first time I saw the Carlos juicebox a few months ago, but never got around to putting it together until last night.

Some concepts that I am trying to test with this are:
1) Bottom feed on the 510. There are a lot of top feed juicemods showing up lately, put I have concerns with needing to "learn" that type of system. It seems like flooding would be very easy until you really had the feel. So far with this setup, I can just push the bottle until I see juice at the threads, and then when I release, it sucks the juice back up. Very little leakage and zero flooding.

2) No hose. I didn't want to add extra hose between the bottle and connector. It seems like that would take an extra long push to get the juice where you want it, and take up extra room.

3) No switch. I don't really see the need for a switch. It just takes up room. In this mod I have just placed a spring in the bottom. To activate the unit you just press down on the battery, which compresses the spring and completes the circuit.

This is not intended to be 'pretty'. I am just testing concepts at this point. As you can see, it is extremely basic. No switch, no tube, no light. It is built in a cheap little battery box. I had started with a ratshack project box, but didn't like all the extra space. I'm not a "glass half full" or "glass half empty" guy. I'm a "glass is twice as big as it needs to be" kinda guy. I noticed that a battery and 6ml bottle would fit in the batt box, so I just went with it.

Anyway...
Here is the box...

Box opened...

Batt Out...

Everything out (completely gutted)...

As you can see, it's about as simple as it gets. About 5 bucks worth of parts, couple hour of build time (for my first one, my next one will probably go together in under an hour). And as I said, not pretty, but so far it's working like a champ.

My next improvement (other than to make it not so ugly) is to put a catch cup around the threads. That way you can squeeze until you actually see juice in the cup then let it suck back. With that there should be zero leakage.

**I would like to thank petercro for the inspiration to do this. While I had the idea long before I saw his mod, I just wasn't motivated to put it together until I saw that his was actually working.

nice, i dont understand whats on top of the bottle though?

It's just 510 threads with a brass tube that goes into the atty. Then it is all attached to the bottle cap with epoxy. The epoxy also seals everything up and keeps the feed tube centered in the connector. Also prevents anything from moving and shorting.

Here's a little better pic....

Nice and simple HP.

Quick question, did you buy the copper foil/tape locally? I've looked but haven't found any locally and I'm afraid if I order online I'll end up buying $100+ worth of other someday useful items!

 

[highping]

I got a couple sheets of it from a metal supplier. A 4"x4" sheet was only a couple bucks. I got it when I ordered lots of tubing in various sizes for another mod I'm working on. I got sheets of 18 and 24 gauge, I think that was the 18 I used here. The shipping was a little ridiculous on this order though. I got $19 worth of metal and paid around $18 for the shipping . I *think* you can get some small sheets at Hobby stores. That's where I got the small tubing that I used in this mod. This mod required so little copper, that I probably could have pilfered it from lots of different things around the house. (doesn't have to be copper either, just something conductive, and solderable)

very simple and i like it.

Saw a great design today, thanks to Mike.
Hghping I have just put together the same bottle atty connection and I'm waiting for epoxy to dry.
You can't get any more basic than your build. And I do like basic.
The simplicity is great.
How is the air flow on the 510, without the base air hole in use.
Good vape, Medium vape?
Is the brass pipe in the bottle the same one as is soldered in the battery connector?
If you need copper, try plumbing piping, cut down middle and hammer flat.
If you need copper tape, MastiffMike / Highping, PM me, I have a spare role or two.
Would be happy to forward to you both.

Nice one.

Well said. Well done.

Which design petercro? I'd like to see it. (is it the mahmba 2 by any chance?)

Yeah, I figure the less things than can go wrong, the less will go wrong. Plus, I was just wanting to get this thing slapped together so I could see how it was going to act. There are many things that need improving...
The "switch" for one, needs to come out of the box, so I don't have to push my finger down into the box to get it to fire. (pretty small detail, and probably has a very simple remedy...like a little 3/8 copper endcap cut short and soldered to the top plate).
Also like I mentioned in the OP, if the threads had a little "catch cup" around them, I could just pump until there is juice in the cup, then let it get sucked back.
And I need to come up with a little less 'ghetto' looking box to put it in. I would love to be able to mold and shape my own plastic case for it (like tinear has done with his mahmba), but I just don't have the knowledge (yet).

How is the air flow on the 510, without the base air hole in use.
Good vape, Medium vape?
Air flow is fine. Most BB mods restrict flow through the center hole on the atty, so it pretty much hits like my chucks.

Is the brass pipe in the bottle the same one as is soldered in the battery connector?
Yes, the tube is a solid piece that runs from the atty strait down into the bottle. But it is not soldered to the connector at all. The epoxy keeps it centered in the connector and isolated from the outer threads. The white wire is soldered to the outside of the tube just above the bottle cap and the black wire is soldered to the outside of the connector. Then the whole thing is covered in the epoxy.

If you need copper, try plumbing piping, cut down middle and hammer flat.
Good idea for a copper sheet source.

If you need copper tape, MastiffMike / Highping, PM me, I have a spare role or two.

Appreciate the offer, but I still have a sheet of the 24 gauge copper that is very thin and bendable. Just curious, can you solder to that tape?

Nice one.

Saw a great design today, thanks to Mike. I knew you'd like that. It's easy to appreciate good engineering/design/build quality.

Good advice, the hobby shop near me does sell sheets, just not adhesive rolls.
If you need copper tape, MastiffMike / Highping, PM me, I have a spare role or two. Appreciate the offer but shipping would cost a bunch! I've found a few places online that sell it, just nobody locally and the online places aren't my usual sources for supplies.
Would be happy to forward to you both.

Nice one.

Come on HP, tell us how it vapes!!! Also, I noticed the pipe in the bottle doesn't go down to the bottom. Is there an ideal length it should be?

Thanks!

OH, HP's red is better than mine!

 

[clyde2801]

Does it draw juice into the atty when you inhale on a full bottle? I'm trying to decide if peter's box does that as a quirk of using the rn4081.

 

[petercro]

(is it the mahmba 2 by any chance?)

OH YES ( I would kill to be able to fab a case of that shape and standard).

Just curious, can you solder to that tape?

Yes solders like a dream (no curling).

Great Idea not soldering brass tube in battery connector.
(Its a pain in the .... to do.

So far it's not drawing on its own, which is what I was hoping for by making it a short strait shot. But I also have not filled the bottle yet. I wanted to make sure it wasn't going to bleed all over the place before I filled it up.

MM: It vapes just like any other 18650 mod I've tried. Very consistent hits. However, I am not using my all day vape juice in it yet, (right now I have some 12mg french vanilla coffee in it), so I won't know until I switch the juice to my usual 35mg 'cool raspberry'. Being my all day vape, I know exactly how that should hit on my 510 chuck, so I will be able to make a better comparison. (I just didn't want to waste the precious stuff until I knew it didn't leak )
Oh and BTW... that tube should go to the bottom, it just kinda ended up that way so I left it alone. Will fix in my next attempt.

Doesn't the 510 have 4 side holes while the 4081 have just 2.
May make the difference.

35mg 'cool raspberry'
Sounds a good vape. Whats your supplier?

Don't make my mistake and cut the tube the perfect lengh.
Sat flat on the bottle bottem (Duhhhh).
Cut it on an angle.

No, the 510 has two side holes like the 4081.

35mg 'cool raspberry'

Vermont Vapor...You gotta like menthol though. It's about 80% cool and 20% raspberry. It is the most 'menthol' juice I have ever had. It is VG based so it produces a ton of vapor and is very smooth. And, between the '35mg' and the 'menthol', it is a killer throat hit. (most VG's don't have much TH...this one does). Because the raspberry is so subtle, it is one of those flavors that has just never wore out for me.

I want to get it close to the bottom (and cut on an angle like you said). The advantage of being close to the bottom, is that when you tip it over, the end of the tube is in the air bubble and juice doesn't run out. The way it is now (if the bottle was more full), if I turn it upside down it would probably run out. (maybe) the vacuum may hold it in anyway IDK

Your answer is correct, it was my question which was wrong.
Doesn't the 510 battery connector have 4 air inlet holes while the 4081
battery connector only have two.

Allowing more air to the atty from the sides rather than sucking up liquid
from a full bottle.

 

[highping]

You are correct, petercro. The 510 threads do have 4 holes around the connector. I'm still not sure if this will be self feeding once the bottle is filled. I haven't filled the bottle the rest of the way yet.

I will be building the second one tonight with a couple of the improvements I have been pondering. One of the improvements should be pretty cool. Don't want to give it away yet because I don't know if it's going to work or not, but here's a hint... Wireless, clip-in bottle connector.

Didn't get to work on it much last night, but here's a little preview of the new wireless clip-in bottle. I have started building the clips but just haven't put them in a box yet. Trying to work out the best way to do the switching mechanically.
