Anyone try Oumier Wasp Nano ?

Lower the coil to reduce the whistle,if you raise the coil you get a lot of spit back.

 

Thanks for the reply. I’ll give that a shot next time I rewick. But so far, no issues with spitback.

 

I got 2...one by mistake!

My experience so far:

- nice flavour, but I need to build the coil higher ie the lower part of the coil can be seen through the airholes
- the top cap is terribly looose...
- very airy, I need to close down significantly, but if too closed the flavour takes a hit
- I use with a 510 driptip, as the open cap is too wide for me to be comfortable
- No real issues with spitback so far
-Noisy as hell LOL

 

No issues with the cap fit so far. But only been using it for a few hours. And I kinda like the drip tip….not my favorite but find it comfortable enough. But will try the 510’s I got and see how they feel.

My build is a 3mm ID spaced Clapton – can just see the bottom of the coils through the air holes. Really please with its performance so far, just not particularly fond of the tune it whistles when I vape.

It doesn’t whistle when I take a pull without firing the mod. There some air pressure vs heat physics for you mathematicians out there. Also adjusting the airflow counter clockwise, once I reach just past half closed the whistling stops. Adjusting it clockwise the whistling remains until completely closed. So obviously there is something in that area of the coil that’s causing it to whistle. Up until now I’ve only been adjusting the airflow clockwise (note to self).

 

Dropping the coil a bit has made it worse. Now it whistles no matter where the air flow adjustment is set at. With a regular pull measured at approx. 6 inches away with a SPL meter, I measure 83db. That’s pretty loud! No wonder I hear the neighborhood dogs barking every time I vape! Perhaps a different coil won’t be so bad.

 

You might file gently around the air flow holes with emery board, inside and out. I've filed around the air flow holes of a ChiNaRDA top cap and found that seems to reduce, eliminate whistling. No real guidelines on how much or little you need file as it like most in vaping seems rather subjective. HTH

 

Thanks – I’ll take that under consideration. I’ve rewicked it a couple of times since, it’s still loud in comparison but not Motörhead loud! For what I spent on it, it is what it is. Given how easy it is to wick, and how little cotton is needed, I’ll probably just use it to sample juices at some of the e-juice bars in the hood. Regardless of it’s faults, it’s still a million times better than those beat-up atomizers used by shops. Some are friggin disgusting

 

I found a tip somewhere, they recommend either a 2.5mm or 3.5mm i.d. Coil helps with the whistling & also to tuck the wicks so that they are cleared under the coil. It worked for me.

 

Thanks. I’ll that that under consideration

 

Hope folks don't mind me reviving this thread. Just joined the board.

I love the Wasp for a lot of the same reasons as others: it's inexpensive, easy to build on, is forgiving of even my lazy half-assed wicking. Dripping through the cap is simple. I've taught myself to vape nic on this thing and I can't imagine it being any easier.

Not being an experience vaper I can't comment on flavour or vapour production but I don't really care about clouds and I don't have a flavour I like much anyway. I started with a 1.2ohm coil and kept building coils with higher resistance and liking each one better than the last. Right now I'm using it at 10W@2.63ohms.

I never get spitback but I think it's because I'm running at such a low temp. It does pop on occasion if I go too long between drips and I do taste those just fine

A couple little gripes about my little Wasp Nano:

The AF can only be reduced so much. I'd get it down to a pinhole if I could but the other ends of the AF slots ends up passing the edges of the blocks and opening onto the deck. I sometimes work around it by closing it as much as possible, then covering one hole with my thumb -- which makes the draw almost perfect -- but it's also awkward so I usually end up not bothering. I don't get any whistling but I also don't pull very hard.

The 510 pin is a little short. I saw there was another thread about this so it's not just me. I have a heatsink that works with another atomizer but not this one, so if I forget to take off the heatsink the mod doesn't detect a coil in the Wasp. The female end of the heatsink fixed pin seems to be a tiny bit deeper than the spring-loaded one on my mod (which makes sense) and the Wasp pin doesn't reach it. Not a big deal as I don't need the heatsink for vaping nic so I just leave it off and the mod picks it up fine.

Does anyone know a source for the glass or resin caps? I don't like the stock cap (I have the white acrylic). Maybe I'm spoiled by the steel and glass tips on my other atomizer but it just feels cheap and... plasticky. I regret not shelling out a few extra loonies for one of those models now but can't justify picking up an entire unit just for the cap. I know I could just throw a 510 tip on there but I like using the cap as is, just not crazy about the material.

Here's the ultem (pei) cap a lot of us use.

Thanks, I might get one just to check it out. I've tried ultem on other devices and didn't mind it, aside from the appearance.

Hmm I thought the translucent ones were glass but now I see that they're actually polycarbonate. So... I guess I'm stuck with plastic, no matter what I choose. Glass would have had to have been been super thin anyway, and I would have broken it no question. Clumsy that way.

 

Yep, and not all plastics are created equal. Polycarbonate is allergic to cinnamon and citric acid. Cracks quickly. I've never had a problem with PEI (ultem), even though like you said, it ain't the purdiest.

BTW, the wasp was designed for larger coils and higher wattage vaping than you described. I run my airflow wide open at 60-ish watts. Nice flavor there.

 

I know but this is the way I like it. It's not ideal but it works for me while I figure out my next atomizer, probably a tank.

Didn't have much time to write a more thoughtful answer before. BTW thanks everyone for the suggestions. This is a remarkably helpful and generous forum.

Originally, I got into vaping nic from the other side -- my ehpro mod was purchased to power a Saionara atomizer. Doing research on coil options for that atty/mod settings/battery selection/etc., a lot of the resources were from the e-cig world and I ended up picking up a lot of info by osmosis. So I got that there are different vaping styles and that I didn't know mine. I also got that there are a gazillion flavours and that I didn't know what I was going to like.

I decided to pick up the Wasp because (1) it was inexpensive, (2) reviews indicated that it was easy enough to build on that one could try different coils and (3) as a dripper it would be easy to try different liquid ratios, flavours and nic strengths.

For ~20CAD at DashVapes on Adelaide I could dip a toe and see if vaping nic was something I wanted to take up. Plus it's getting cold in Toronto and smoking on the balcony is losing some of its charm. Having the option of scratching my nic itch on my sofa in my PJ's has a certain appeal

That's it. So I started with a simple ~1 ohm coil (god that thing was ugly, I wish I had taken a pic), then tried larger and smaller ID, more and less wraps, higher and lower wattage, more and less airflow, higher and lower PG... you get the picture. I went with whatever felt good and so here I am today at 2.63ohms/10W.

I feel like I've gotten as close as I can with this atomizer, recognizing as @cigatron pointed out that although it is amazingly versatile, the Wasp isn't really designed to be used the way I seem to want to use it.

So I'm going to move on to something that works better for me, which I now know means a fairly-to-very restricted airflow. And a tank for when I'm driving. I love my little Wasp tho, and won't be retiring it anytime soon. It's just too much fun. I mean seriously, what's not to like about this?
