Call me Captain Obvious, but something just occurred to me. For newbie drippers, those who vape in the dark, and the generally messy, it seems that just a drop of juice inside the atty connection could cause the sensors to not properly function, or at least not work at 100% efficiency.

Doubtful, unless they are using some special atty that allows the juice to run down the threads and affect contact.

Last played with the 3ohm 901 atty. But to be honest, I am not in love with that setup on the Darwin. Decent vape, slightly better taste and lessened TH. Has to be juiced almost as much as a 510, so no advantage there. I just got bored with it.

I started to try the Golden Green Automatic Feed System (GG-AFS) 2nd version for all mods. Bought it some 9-10 months ago to go with my GG Telescoping System (GGTS) mod. The AFS is a feed system that uses gravity and air pressure to feed juice to a 901 atty secured to a tank full of ejuice. A control ring at the bottom of the mod allows you to fine tune the atty/juice ratio of the mod like an old fashioned automobile carburetor. I moved on to the AVS made by GG specifically for the GGTS, but intuitively held onto my 'all mods'. I even held onto a used but serviceable 6v 901 atty made by GG specifically for the AFSv2, the i6.

Fortunately, I have a good 510 to 901 adapter, so it was pretty simple to attach the AFS to the Darwin. The atty connection can't be swiveled all the way down with the mod, so it cannot be turned off. This doesn't look like it should pose a problem as the button requires too firm of a press to prevent an accidental misfire, and the LCD screen staying on should have a negligible impact on battery life. The AFS looks off center and out of place on the Darwin, but still allows the mod to stand upright.

I'm still trying to decide what to think about this setup on the Darwin. It has a lot of good things going for it: 5-6ml juice storage, a good taste and decent TH when matched up with a HV 901, and almost effortless vaping if everything is working right. Once properly set up and adjusted, simply inhaling draws the right amount of juice into the atty from the tank. The control ring allows me to fine tune the amount of juice being taken into the atty with every inhale, which can help to compensate for different voltages, juice viscosities, and what kind of draw I happen to be using at the moment. Finally, the juice in the tank can help the atty from overheating from use, similar to putting a fuel pump in the middle of a gas tank on a car.

But it's not quite perfect. When using attys on the AFS instead of perforated KR808D-1 cartos, the it has a tendency to seep or outright leak ejuice. (To be honest, minimal seepage is still an improvement over spillage and seepage I experienced manually dripping attys and cartos.) The AFS can be finicky to be point of being temperamental if it is not properly assembled and cleaned.
These traits, along with fine tuning the control ring, does add an element of complexity not present with simply dripping an atomizer.

It's the age old tug of war between having precise control versus enjoying simplicity. And to a certain degree, it's fairly subjective: some vapers want to be able to simply hit a button and get a vape, others would rather fiddle with a couple of settings to get the perfect vape. The electronics and interface of the Darwin strikes a nice balance between these two opposites, and I'm not sure how the AFS will affect that in daily use. At least the Darwin can easily switch between many atty/carto/juicing options, just not all of them perfectly.

Fortunately in the case of this review, the recent blizzard in reddirtland will confine me to my house for at least another day, and give me the opportunity to experience this setup in detail. I'll report back on later on in the day on its general usability, vaping experience, seepage and/or leakage issues, and battery life. Presuming of course I don't die of a nicotine overdose in the meanwhile.

And before you say it, I'm well aware that there's a new version of the AFS. However the v3 is a) larger than the v2, b) out of stock, and c) has a list price of $92.00 plus shipping. Cleaomizers are on the way, and I'd really like to try the Map Tank Mod and the Ato-miser, but spending almost a car payment on vaping in a month is bad enough; a few more add ons will take me into house payment territory.

snowpocalypse 2011 is not helping a light sleeper like me. As much as I didn't like the set up and breaking down of the ggafs I gotta say it gave me some of the most memorable flavor production I ever had with the same juice compare to other setups. I'm not surprised that your getting good results with it on the darwin :) I'm sure your turning a lot people onto the darwin with your updates so I think Drew should just give a you an ato-miser to play with :laugh:

i got a cig .... with an X in a circle in my atom circle logo (with the O in the middle) this morning... and weird things happening with the batt icon...

the batt was not low.. it was the joye 510 2.4 Ohm atty i'm sure.. it started out new a couple days ago and quickly the Ohm reading kept creeping up... over 3.0 the second day.
I popped it on my Provari and it read 3.5, then started going up up ridiculously...

i think it's a bad atty...

I leave the arm up all day too mama, but i am a fiend, so i am compelled to vape every drop before i put it down... no more dripping right into the dial slot for me.

thanks Clyde, your Frankenatty story cured me of being too conservative with the watt setting... go for the gusto now... after all this is a state of the art PV. !

I learned to be careful with the number of drops again, like i did before i got into the bottom feeders, and even with the Provari's deep drip well. It is the "way" to drip properly anyway.

I got tired of inconsistent feeding with the squeezer bottom feeders quickly; there's something about knowing exactly how much juice you are putting in the atty (and from the top...which is imo unbeatable).
I even drip with my Phidias which is the only bottom feeder I kept (and it's a "gravity" feed).

I use bottle / needle set ups for dripping.

Right now I've got a 3.5 Ohm 306 Ikenvape on and it is just very cool. or hot. wonderful.

Oh yeah, i have neen using the USB cable that I have from my USB eGo batt to charge it ... or use and charge at the same time ala pass/through...

Thanks for all the tips and inside info.

It shouldn't make a noticeable difference. Juice is non-conductive (or at least in the megohm range), so it shouldn't affect operation or efficiency.

Think about it. if juice could cause a short in the atty connector, it could cause a short between one side of the coil and the other. The coil is swimming in juice if you're a dripper, and it's never been an issue.

Only thing I noticed with my screen, besides the small scratch, is that, when I put the arm down, the screen blinks and has a ------------ through it before it goes off. Also, the screen doesn't go off every time when the arm "clicks." Some times I have to push it just a tad further to get the screen off.

@ ukeman - You can put the arm down and turn the Darwin upside down to prevent leakage from the atty.

Benjaymin, thanks for the compliment. I like to report what I find good and bad about a mod., especially after using it for a while. If my bumbling dumbassery can help others in the vaping community, cool. And while it would be uber-cool if someone were to send me something to try out on the Darwin, I never expect it. I used to be really bad about telling others what I think they should do with their time, money and possessions, (it's easy for me to be a big shot when I've got someone else's checkbook) and that's a character flaw that I have to guard against.

mama cat, my display does the same thing. I don't even pay attention to it anymore.

Ukeman, I hear what you're saying, but my Grand is pretty darned good about getting the right amount of juice to the atty/carto after I mastered a slight learning curve. One of the things that intrigued me about the Darwin's promise-perfect power every time-was the question if constant power or constant juice is more imporant to the vaping equation. If I were a true blue dripper or uber HV fan, I don't think there would be as much of a point to the review; only to compare the Darwin's features to existing 2nd and 4th gen mods and confirm or deny that they could withstand extended use and abuse.

I think it will get really interesting to go back to the Reo Grand after I've played with the Darwin for a month or six weeks and compare the two. Hopefully, I'll be able to tear it out of my office manager's hands at that time.

Ah, the thought of sitting in my easy chair all day, playing with the Darwin. Then I realized I had to jump my old diesel beetle and get it running, shovel the driveway, get Dad's car running as a backup, salt what hadn't been shoveled, run and pick up groceries and the wife's prescription while keeping an eye on the two teenage boys and two teenage girls in my house, one of them being my daughter.

If I get another day off, it's going to kill me.

Did get the chance to play with the setup during breaks. Once the CR and watts were dialed in, this thing can quickly fill a room with vape. 8.5 watts is a nice place for the darwin, and it hits the 4.5ohm atty with 6.3 volts. Seepage didn't seem to be too bad on the AFS, but a couple of times I could run my fingers around the air inlet holes above the control ring and see a ring of juice on them. I must have vapid or seeped more than I thought, i'm down to @1ml of juice after vaping it off and on since 8am. Battery shows to be at roughly 75% of charge.

And the AFS vapes on the Darwin just as it does on the GGTS. Really dense, warm, wet tasty vape with lessened TH over a LR 510, but the HV atty helps to lessen the gap between the two. The setup really brings out the taste of sweeter juices, which is a really good thing for a guy on a diet.

I think I'm going to keep this setup for the time being, or at least I can find and afford to try something else. Clearomizers are on the way, and the map tank mod and ato-miser are on hold until I make some more money.

It's pretty subjective at this point, but for me the strengths of the 6v AFS outweigh the lessened TH, occasional seepage and increased unwieldiness of the Darwin. Then again, it shouldn't be too hard to carry around a spare atomizer and juice bottle and quickly have a change of pace.

I'll check in if there's anything new to report.

Battery died at 7:30 pm, almost 12 hours from being taken off of the charger. Went through one afs tank (5-6) ounces, and maybe an ounce of the new tank. Some of that may have been seepage, but not much.

I was about to say that I was a bit disappointed with battery performance, but I did go through over 6 ounces of juice! It may be another possible drawback to using the AFS on the Darwin with a HV atty.

But I'm trying to be realistic about the battery, it is only rated at 1800 mah. Granted, it is a 'for real' rating, as opposed to tubular battys, but I don't think that battery is meant to be a magical never ending power source. A good accessory for this mod would be a USB to mini usb cord to take more advanntage of it's pass-through capacity. My old motorola phone uses the same charger (crap, I cant remember its name, but its the smaller version of the razor) so I think I should be able to find some options there.
