Hey, my first attempt was quickly followed by my second attempt today. My first was on a little knock-off china-made genesis style atomizer. I used a 500 mesh with some medical gauze string wrapped around the top with a 5/6 wrap of 30g kanthal to get 2 ohms (checked using a $10 multimeter from amazon, not the most accurate) which I popped onto a standard ego 900mah battery running at its default of 3.3V or so. I doused the tip with e juice and fired away, and i was disappointed as it barely produced any vapor. I then removed the cotton fiber off the top and rewrapped the kanthal - still not enough vapor. Finally, i cut it down to a 3/4 wrap (around 1.6 ohms, give or take) and voila, it was popping and sizzling like i've seen in countless videos. I had a hotspot on the top coil which was remedied by just kinking the wire against the middle post. I filled the tank with some strawberry from one vendor which sucked, and banana from another i got as a sampler (i did this so i wouldn't feel bad if it was a failure and i had to dump the juice). Metallic taste was prominent right away for the first dozen or so pulls. I stepped away for an hour and a half, returned, and it was AWESOME. i didnt care much for the flavor of the e juice, but the experience was unlike anything i got out of my carto tank, carto, bcc, vivi nova. Clouds of vapor, smooth hit, no dry hits AT ALL, no burnt taste even taking the full drag all the way to the 8 second cut off, and all this from a setup using a 15 dollar standard ego battery - i was satisfied. My second endeavor was with my vivi nova. i made a u wick. my torch went out half way through oxidizing, but i did focus on the "U" part of the wick where the coil makes contact (i think that it isn't imperative to oxidize the area which is not intimate with the coil, i could be completely wrong though) and then i wrapped the same 30g kanthal to a 5/6 wrap and popped it on my vision spinner (after checking it with a multimeter) and turned it to the lowest voltage and fired and saw the coils all swell up fiery orange - this was a great feeling. I loaded this one up with a hodge-podge mix of e liquids (minthol, strawberry lemonade, hawk sauce, razzleberry) and vaped away. Metallic taste like no other. Thought i failed. Sure enough, after vaping 1 mL or so and then topping off with some more e juice, it was STELLAR, vaping at 4.3V. Clouds of vapor, long draws with no burning or dryness whatsoever and crisp flavor. None of those features were consistently present with the stock silica wick head.
All in all, i still prefer my free zen style knockoff coupled with my dinky ego battery. I will eventually spring for a better device (looking at the vamo, particularly from vaporbreak for 27 bucks) but for now i wanna just enjoy maximizing my vape with the tools i have already.
Sorry for the novel, I am just very excited and elated to find such a perfect, economical vape less than 2 months after I first started with a logic e cig i got at a gas station. this forum rocks!
