Hi all,
It's been a week with the WIZ and finally had some time to give some updates. It does not go through juice as much as you think it would. 5ml lasts for about 2.5 days for me, the batteries last that long as well, I replace the batteries when I fill it up so not sure exactly how long the batteries will go. One thing you can not do is use juice with any kind coloring in it. The atomizer will clog and vapor will diminish to nothing.

I've updated the sketch of the working parts and taken a couple pics of the circuit board. I'll try to come up with a schematic but one device has me unsure exactly what it is (more on that later).

Bottom of the circuit board. Here you can see the epoxy covered device. I originally thought this to be a microprocessor but am having second thoughts about that now. More to come later when I get time.

a picture of the atty would be helpfull . i love the concept it is technically a catomizer atty ,but in a glass. my question is why the second glass mini atty. i have seen work done on a home maded atty using pyrex glass type combobulation, but he had sealed it with a blow torch making it a sort of light bulb . but, needed a lot of power to work .this option of using the glass as a straw is brilliant,but why 2

What flavors of Dekang juice are you using, Charged? The tobacco flavor juice (from photos on their site) looks like it has a light color to it....

Fairlane64: Get One! Using post #26 on this thread, you can get one for right around $21.00 including shipping.
The more people who are messing around w/these things, the more we will learn!

Hi all, thanks for the posts. If the liquid is clear you'll be good (if you can see through it) if you can't see through it it will clog the glass tube pretty quick. Fortunate for me I had a spare on the shelf. The cost is minimal considering you get the atomizer/battery holder and 3 ounces of PG fluid for $20 and the AA batteries are cheap. If you order 2 the shipping stays the same so you can decrease you cost per unit and have a backup just in case. If I can't get the glass tube cleaned out I'll be cutting it apart to get some better pics of the atomizer setup. I'm going to try soaking it over night in some crest mouthwash and efferdent to see if it clears the tube. It's quite nice to just sit in front of the TV for 3-4hrs and vape without fiddling with juice or carts or anything else for that matter.

I've been using Dekang peach, apple, cola, and menthol. All the Dekang juice I have it totally clear and works great. I made some of my own with 60mg PG mixed with some VG and capella flavorings and they all worked well. I had a problem when I tried rootbeer. It was a mix from a well known vendor on here. I attribute the clog issue with the coloring (at least that's what I'm guessing). The juice that clogged it up was very dark and you couldn't see through it at all.

SV, a slight color liquid should be fine. Hope your device shows up soon. I'm anxious to here your thoughts.

Not sure why there is 2, It appears when the liquid hits the 1st one the atomized liquid is not really fine droplets, but atomizes to much finer droplets when it hits the second one.
Hard to see but here is a pic.

The second atomizer is used because the air is pressurized over the coil rather than negative gravity from our suction drawing air across the coil. Because of the positive pressure, The first coil cools too quickly to reach full vaporization heat ... so, the second coil is in place to break down the original product of the first, and vaporize the partially heated cloud to fruition.

I don't think they designed it to be sucked on. I figure they are going for volume and are preheating/expanding the pg. Well it sounded good.:D

Or did they design it for sucking?:thumbs:

It could be to get some velocity, better dissipation. Narrowing chambers, higher heat in succession. A loose venturi? Don't know just thought rambling.

No.. NO.... This is as opposed to the e-cig itself. Yes, expension is what this device here is intended for. The e-cig uses negative gravity from our suction on the device but this device uses positive pressure from an air bladder to move the juice to the atty... At the same rate, the result therefore cools the atty quicker than what the e-cig does... and that requires it to have the second atty to further break the cloud down into a full vapor instead of a partially heated cloud.

Another question in my mind for charged is? When you take a hit off of this thing, do you have a lot of heat in the vapor and as a comparison, how do the flavors that your have used in the e-cigs compare in this unit...... Are they deminished by the method, enhanced a little better than in the e-cigs you have used, or remain unchanged??? Another thing that I would be interested in knowing, What actual supplied voltage is being introduced to the atty itself
( past all the control devices ).

Negative gravity?? Dark matter? OK I knew what you meant, just couldn't resist it.:D

LOL!!! Bad at explainations... don't have a filter in line between my brain and the voicebox ... and if I did, It would be off getting fixed most of the time!!!
ROFL

I definitely want to know how this thing compares in taste and throat hit to a regular e-cig. Thanks for all of the work!

The TH and flavor is improved over the 901 and KR's I've been using. The vapor is not hot but warm. You can control both the flow and amount of heat by varying the amount of pressure you put on the air bladder. It takes a bit to get use to it but once you do, it's excellent.

The resistance across both coils is 3.8 ohms. So if you were running the recommended battery voltages you would have about 9V (1.5x6).
2.34 amps across 3.8 ohms for a power of 21 Watts.
I'm guessing they need that kind of power to overcome the cooling caused by the long metal tube. I'm using NmH 1.2V batts so power to the atty is almost 14 watts.

I get full battery voltage across the atomizer so I'm betting the device on the output of the circuit board connected to the negative side of the atty is a FET and it's being pulled to ground (neg side of batts). It is a hard ground not 1.2V above ground like you would expect from a transistor.

There is a small surface mount 3 terminal SOT-23 3V regulator on the board. It gets power through the switch as shown on my diagram and this in turn powers the unknown epoxy covered component.

Gotta run but I'll be back later with some more voltage measurements.
