My OKR juice box

[smuro04]

I had one of these built previously, but it had some flaws. I wired the trimmer backwards and it bothered me so I tried to put in a new one wired the correct way. Well I fried the chip so I took my time and built another with a nicer trimmer. Here it is:

2xAA enclosure
808-D/901 connector
200g tact switch
OKR T/3 switching regulator
200ohm resistor and 200ohm trimmer
2 x protected 15270 batteries

With moderate vaping I get about 12 hours of vaping time or about 1-2 ml of juice before the batteries need recharged. I love these batteries because they only take about an hour and a half to charge. I may buy a second set of batteries to take with me so I can vape all day.

What do you guys think?

Hi Smuro, Fabulosly well thought out. Great work. Whatere did you find that switch. I looked for a long time and couldn't find one like that. Thats exactly the switch I wanted for my mod. Got a new build coming up so if there is somwhere I can get that switch that would be great.

 

[smuro04]

You can buy the switches from MadVapes with either 100g or 300g actuation pressure. The switch I'm using has a 200g actuation pressure and I bought a bunch in bulk at onlinecomponents.com

Nice work. How did you make that atomiser-bottle connection?

I was about to order reo grand but then again i didnt want to invest 150d at this moment. Now im waiting mail to receive parts for bottom feed mod. Im going to use kis 3r33 and 4 or 8ml juice bottle depending if that 8ml bottle fits in 14mm hole. I dont think im able to fit the parts as snug as u did

im totally new to bottom feed and really looking forward to make my first prototype

 

[smuro04]

The connection between the bottle and carto is quite simple really. It's just your standard 808-D/901 connector with a large hole (a 510 will not fit in this mod, trust me. Turns out, I like the 901's flavor better than the 510 anyway) and a standard 3ml dropper bottle with the dropper tip trimmed down about 1/8"-3/16" and a 20g blunt syringe through the dropper tip that feeds the liquid from the bottle to the carto. Check it out:

oh its so simple. I have seen those before but i thought they would leak the juice all over inside the mod.

 

[smuro04]

It depends.

Atomizers are notorious for leaking with this type of setup. Using thicker juices and thicker gauge syringes helps prevent leaks but will not stop them all together. You must be vigilant when squonking the bottle if using an atomizer. A 16g needle works well for atomizers, but is a tight fit through the connector.

I prefer cartomizers on my bottom feeders and I use 20g needles with them for optimal airflow and ease of inserting the needle. I use juices a little on the thicker side, about 50-60% VG. With thicker juices the cartomizers tend to be more forgiving if you feed too much liquid into them and won't leak much if anything into the mod.

Im going for atomizer on my bottom feed mod, i rather use cartotank with cartomizers.

I ordered this Pre Assembled Bottom Feeding Connector and silicon tube for my mod so i quess that works out just fine with atomizers.


thanks for the information.

That's not a bad deal for pre soldered. just keep in mind that your mod will now be a "tilt and squeeze" since the needle won't run all the way down into the bottle. Not that big of a deal and I personally think it's the better way to go for atomizers. There's nothing worse than trying to clean juice out form all inside a box mod.

Tubing from the connecter nipple into the bottle .... No tilt needed.

 

[smuro04]

The tube on the connector in the link is way too short to reach the bottom of the bottle. You would have to tilt with that set-up.

 

[smuro04]

The black one has seen better days. The pot had a flat spot, cracks all through the case and the connector came loose. Decided to whip up a white one tonight. Just finished it.

Waouhhhhhhhhhhhhh !!!! I'm really impressed.....
I'm BF addict and start my homemade...I'm really interrested !

 

[MasterofNone]

I WANT THIS. This exact one. I think it looks better than the "classy" bf mods. When I get some money I'm gonna try my hand at this one as a precursor to making a nice wooden one( same size) maybe this is a dumb question, but where did you get the okr t3 voltage adjuster, we, thingy? lol

 

[smuro04]

Digikey.com. They're like 6 bucks a pop.

 

[Firstcig]

wow great mod I'd buy that for sure.

Man, I was all over Onlinecomponents.com and MadVapes and I couldn't find that switch. Is it a tact or a push button? What amps does it hold? I need switch!

 

[smuro04]

It's a tact switch. It's only rated at 1A/32V but I've never had one fail on me unless I got juice in it.

Thanx, man. Now I get to go shopping to hit that $20 minimum.
