Ze Bulli

derra

Don't know if anyone be interested in this but anyway.
Received the Bulli A2 repairable atomiser yesterday, takes 3 weeks to get it after ordering.
Alec and Gryzor seemed to think the A2 was better than the A2 tank version for performance and setting up so went with that advice.

http://www.bulli-smoker.com/verdampfer-atomizer/bulli-smoker-a1-atomizer-2.html

Pic of mine with eGo 900 mAh battery and eGo cone from the Bulli site.
(Seems i got pic size spot on when i put mine up to the pic)





With this, i can replace the coil and wick to whatever resistance i want, i will be using Joye eGo-T batteries which are around the 3.4 Volts.

A video on how to repair the atomiser is here which was done on the A1 version but am using same procedure for the A2 as the video is on the A2 page on the site when buying.
There is a tank version but as Alec and Gryzor said it can be hard to get right and a lot of users on other sites recommend the A2.

https://www.youtube.com/watch?v=DV6_1uwGo70

To do the above i will need some extra wick and resistance wire to practice with.
I got 10 metres of wick which i believe is hard to source, the resistance wire i believe is Kanthal D - 0.15 mm and got an extra 5 metres of that but in future i may get Kanthal D - 0.16 mm from here instead of the Bulli site.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280559037837
or
http://tinypay.me/search/#q=tag:kanthal-heating-resistance-wire

Robbed this off another site but he explains the resistance well..

''The resistance is set by the effective length of the wire, and the cross-sectional area of the wire.
I say effective length, because tightly packed coils will short out. If two coils are touching, the effective length is reduced by one coil.

0.20 Kanthal wire has a resistance of 43.8ohms per metre. To get a 1.5ohm coil, you need to use a 34.25mm length of wire (1000/43.8 x 1.5). Note that this is the length of exposed wire between the terminals. The wire clamped inside the terminal is shorted by the terminal itself, and doesn't count.

How you wind the wire doesn't affect the resistance, as long as it doesn't short back to itself.
A straight piece of wire 34.25mm long will have the same resistance as a 34.25mm length with two big coils, or 3 medium coils, or 4 small coils, or five tiny coils.

The layout of the coils around the wick affects how the heat is transferred to the juice, and thus the amount and quality of vapour produced. This is where experimentation comes into play. I'd guess that a longer, looser, coiled section would work better than a short,tight, coiled section with longer ends. That's only a guess, mind.

Thinner wire has a higher resistance. In theory resistance is inversely proportional to the cross-sectional area, or the square of the radius of the cross-section. 0.13 wire has more than twice the resistance of 0.20 wire. I say in theory, because the figures don't work out exactly, but are pretty close. I guess maybe skin effect plays a part?
Whatever, the quoted ohms per metre lets you work out how much wire to use to get the required resistance - 1.5ohms needs:

34.25mm of 0.20 wire
22.5mm of 0.16 wire
15mm of .013 wire ''

It would be very hard i think at this early stage to work with short distances like that as it does take practice to get it right but i have a good idea how to get the resistance i want.
A multimeter is needed to measure the resistance by placing the probes on the screws.



And by putting an extra loop around the wick will help would help ensure it does not touch off the inside threads although ya be using alot of wick.



Blank Cartridges DSE-701 fits onto the atomiser.
http://www.thevapourstore.ie/blank-cartridges/5-blank-cartridges-for-dse-701/prod_188.html

The cost was..
€50 for the stainless steel A2 atomiser.
€16 for 10 metres of wick.
€10 for 5 metres of resistance wire
€10 for stainless steel cone to make it look better on eGO battery
€7 registered delivery

All in all it was €92:45 to be exact which is alot of cartomisers some will say or around 9 atomisers but i wanted something that will last longer and something to play with.

I think when heading out i will use a DCC in case i was to lose it or anything or maybe buy another in future.
If all you want is plug and play then this is'nt for you as there is alot of thinkering with this but very rewarding.

Would not work straight out of the box yesterday as 3 batteries i had was not making contact properly. I thought there was a problem with the way it came regarding the winding so i wasted a bit trying it myself but was a good learning curve!

After some reading and fiddling about i got it firing up, so went and made a coil at 2.3 Ohms making sure to have it on opposite of the air hole.

So far it has been excellent, great taste, smooth draw with plenty of vapour. Feels very clean vaping, no leaking or drops going into your mouth.
I'm itching to take it apart to try new resistance and coils etc as there is so many options with this atomiser. I could write for ages about different aspects of it but it's definitely the King of Vapour for me so far.

All of the above is alot to take in and i left a fair bit out, but once ya flick through the threads below it will make alot more sense.

Jaze, you'd need a cigarette after that!

Fair play to you. I'd be in the 'a lot of cartomisers' camp myself, though.

Bubba9

Well done. My one reservation is being confined to using cartridges which are pretty useless if you vape at higher voltages. Is the capacity the same as the 510 cartridge? There's an excellent tutorial/review of the tank version here:

I will always have a couple cartomisers handy to use when on a night out and they seem to work great and seem reliable though a little bit too harsh for me.
I like the taste of the juices out of this atty, change to whatever resistance i want and repair it straight away when neccesary.

I have only vaped with the eGo batteries regulated at 3.4 v so far so don't know about vaping at different voltages. When looking to buy this i would of probably preferred to see a tank on the A2 being familiar with the tanks but now that i have used the 701 cartridge it does'nt bother me in the slightest as the way the whole thing works is far superior to anything i have tried.

After reading about the A2-Tank, i was glad i went with the A2 as ya have to also get the wick in the spike so less to worry about it performing good.

Regards the capacity, i just take the filler out , pour some juice in halfway, place filler back in and pour some more on top and leave it a while. Not bothered about how much it takes as it performs and wicks so well.

One of the lads that's more experienced with the Bulli will answer you better than me.

Ya can try the Italian Mod to turn the cartridge into a tank which i will do later and see...

Just made a new coil at 2.2 Ohms in less than 5 mins and works a treat also.

Great info there...thanks. Keep us posted on how you get on.

Derra, your some man to risk that much cash, must be the fortune your savin on analogs.
Sooo tempting to get one of these.
94 euro tho, might have to drop some hints for the xmass pressie. What! no it's not too soon to start

Good man Tommy, hope all is well.
I see it as an investment Tommy, well i do now seeing as it works so well
Could of easily been put up For Sale so was a bit of a risk.
I would definitely read up on those threads i linked to to make sure it's something ya would like to use.
I spent €92 but you could bring the cost down to about €65 with less wick, wire and and no cone. I just got the extra as it's €6.99 for postage each time if buying wick from there.

Would love to have a variable voltage for extra options using the Bulli, might look at the eGo booster as don't have the money for Provari or the likes.

tommy2bad

Seen this http://ukvapers.com/topic/8487-we-knew-it-wouldnt-be-longsub-75-factory-produced-vv/ ?
Might be a less expensive option. If you can wait till this vaper ware is no longer 'vapor ware'

Would like to see Irish shops get these ones though..

Great review derra, specially like the links for the wire. Bulli site is a bit pricey for that. Did you come across any for wicking?? I found one thread on ukv some time ago, but i lost interest after about 30 pages of nattering...

I usually go for 4 turns, and that gives me about 2.1ohm....vapes well for me on an ego @3.4...at home then i lash it onto the provari @ 3.7, slight more flavour and vapour...

It's bugging me that i can't get the tank version running properly, i use a 50\50 mix, so maybe i'll try a 100% pg mix and see how that goes...

The wick is froma UK crowd called Hattersley's but they don't sell small amounts of wick, there is a minimum amount that has to be bought but this is the thread ya refer to..
http://ukvapers.com/topic/7447-fibreglass-wick-group-buy/
http://www.hattersley.co.uk/wicks.htm

If there is a couple more Bulli users or people that need wick we can do a group buy ourselves.

There is a video on YouTube about putting a new filter in the 701 cartridge and can't find it right now but i think this is the stuff he uses, that brand anyway.
http://www.zooplus.ie/shop/fish/filters_pumps/filters_and_pumps/caniter_filter/126290

I will just buy the cartridges off the Vapourstore while they have them.

Must be so handy to up the voltage when it pleases ya with the Provari :cool:

Hope ya get the tank version working, am sure there be a tip in a thread somewhere that will get it going properly for ya.

Yeah 4 turns gets me at 2.2 Ohms with the 0.15 wire, might do an extra turn next time but am gonna try hold out and see how long the current wiring and wick lasts.
Gave it a wash earlier and a dry burn, think certain juices and their ingredients causes a bit of gunk on the wiring.

Gryzor

I'd be on for a group buy if it's doable...

I contacted the vapoustore about the carts, she said they were only stocking them for the sake of customers who had bought 701's from them in the past. So, we might see them disappear soon. Refilling the filler on the carts would be alright, the plastic casing seems durable enough methinks...

Whats the weight of the SS one like?? I got the aluminium one, very light, but the threads feel like they might wear over time...

I may get a few anyway, if you find RN4062 Carts on the net, they are the same as DSE 701. The casing seems very durable alright, ya can also wash the filler i think and re use, would'nt be a worry anyway as ya can also buy filler for them.

Yeah i read about the threads on the aluminium alright, might have a problem with the air hole going down to far below the coil, but you can get an O-Ring and put that between the two to keep the air hole at the right level.
I read all DSE carts should have an O-Ring on them but the ones we get from the Vapourstore don't but ya will pick one up somewhere.
I should never have that problem with the stainless, feck all weight in it really as it's only a small device anyway.

Once there is a few of us we'll look into a group buy.

Will bookmark the Petmania store and check back to see when the site is up and running again, none of their stores are near me.
Good to know we can get a filter, don't throw the carts away!

He's a good source for wire so and it's very cheap to get :cool:

Done 3 turns on the 0.15 and have it at 1.5 Ohms.
Tonnes of vapour coming out of this thing, more throat as expected

(After a couple more windings, 1.5 Ohms @ 3.4 volts eGo battery is too harsh, lose out on flavour.)
Will be staying around 2.2 Ohms.

Putting a needle through the air hole to adjust the coil makes a big difference. Any slight change at all makes a big difference to the Bulli.

Will use a bit more wick and wire trying out different ways before i begin to just leave it and let it do it's job before i have to repair.

Have 4 eGo batteries to run it, main thing for me now is trying different juices and not worry about when an atty will stop working.

Great value for the €90 i spent as with the 11 metres of wick i can repair many times over..

I would say there is huge difference between 1.5 ohm & 0.15 mm wire and 1.5 ohm 0.20mm wire
with 3 turns 0.15 mm wire you'll get burn taste pretty quick @ 3.4v , not an issue with 0.20 wire though ( 6 turns covers large area of the wick -- it is not getting dry so quickly )

Will definitely order some of that 0.20 wire to try out.
At the moment i have it at 2.2 Ohms and using 11mg RY4 which is a big drop from 18mg and getting a nice throat hit and plenty of vapour.
Being a user yourself you can understand my opinion changing in different posts regarding the Bulli as there is so many options when using this.

The video i saw before refilling a cartridge with filter.
He lets it stick out the top of the cartridge but the loops of the wick push it back in when screwed in anyway i find.
Got some of the Juwell Filter on Saturday and seems to be doing the trick just fine.
Also ordered a load of the 0.20 Nichrome wire to keep me going for a while!

I would say he making his live too complicated I just cut a piece with the scissors ( 3 cm x 1 cm ), bend it in a half and push it deeply in to the cartridge ( no contact with the coil at all ).... ah , nearly forgot --- i am sticking 2 pieces of a wick ( 2 cm long each into the cartridge aswell -- 0.3 cm out the top ) only those two tails making contact with the coil/ main wick , so there is no nasty taste of a burning filter etc.
Refiling juice with the syringe at home or just dripping onto these tails on the move .( they helps you to refill cartridge nearly fully -- no need to taking filter out )

Thanks yet again Alec, will certainly try this way and see if there is a difference in the performance.
Will also ask in another forum for any more suggestions to try out.

I ordered 10 metres of 3mm braided wick from that UK Vapers group buy subject to when the MOQ is filled.

There are 8 strands in the 3mm, so for every meter of 3mm wick you get 8 times the wick = 800 atomisers using 10cm with each repair
The single strands are then suitable to be used on the Bulli.

This is a single strand of it.



Anyway the point being, if yourself or Alec want some out of it when i get it let me know unless yas have ordered some yourselves since it was pointed out earlier in the thread on where to get it.

Can't beat the unexpected afternoon delivery by An Post
Just got that wire a short while ago and have the Bulli vaping @ 1.6 Ohms.
It's working out very nicely i must say. More than happy with this winding.

Send me a PM with your address Gryzor and i will send ya down a couple metres of it to try.

I love the look of the Bulli, the other one looks a bit too shiny but it's all about performance so will wait and see what the reviews are like on it.
I can't fault the Bulli so won't be in a rush for anything else at the moment.

There are two great repairable Atomisers at the moment IMO

2) iAtty -- more complex , but high capacity (5 ml) and better taste atty

Have not tried that yet Alec.
At the moment i have a winding of 0.15,4GF, 5 turns without using the nail and that works fine at 2.1 Ohms using 11mg juice.
The 0.20 wire is great also for 1.5 Ohms as you suggested so will alternate between the two as ya do !

Might try this wick also sometime, similar price to the Bulli site but it's 2mm wick. Not sure on delivery charges.

Finally got my Bulli back in proper working order...:D

Whenever I cheat on the bulli and use other carto's, they push the centre pin of my ego batteries down a small bit each time I take them on and off (Same with charging the batts). I'm aware of it, so I use a pin to level it up again when I want to use the bulli.

For the last few days, the bulli has been working, but poorly. It was firing, so I never considered the battery connection. Anyway today, I levered it out a bit more, and bobs your uncle, way better performance. Must have been making only the slightest of contacts...

Something others might run into...

derra

Have had to do that with the eGo batteries since i got the Bulli.
Bought a battery couple weeks ago from TBS and the centre post is fixed into position better with no movement at all so it works every time after charging.
Make sure next time you buy one it's the latest version of the battery.
I shorted a fairly new battery the other week, hit the button by mistake as i was prying up the centre post :rolleyes:

Since i went back to the bulli, vapour production hadn't been the same as it was for the couple of months i had used it previously.

I'd been adding an extra half-turn on the wick by mistake, when I was building the atty, resulting in one extra strand of wicking being used. Seems this was too thick, and there was too much juice at the coil. Probably didn't allow the coil to get hot enough, resulting in less vapour..

Got this off the UKVapers site.....
Few more ideas to play with...
Mainly i use the 1st coil and 3rd wick in the diagram.

The coil should be on the opposite side to the air hole. I lift mine up a bit once attached.

As for coil winding, the set up I use most is 4 glass fibre / 4 or 5 turns of wire. 4 turns gives me 2 ohms, 5 turns 2.5 ohms. By 4 glass fibre, I mean the number of strands passing through the coil. To make a "4" wind the wick around your little finger twice. then cut off, flatten against the nail and wind the coil. You should end up with 2 loops of wick on one side and 1 loop plus 2 free ends on the other. You can adjust everything a bit once you've screwed it on and removed the nail. Pull gently to even out the wick lengths. Use the nail to make sure that the coil is evenly spaced.

Here is a diagram showing all the different configurations I've come across on the German forum.

Method 3 allows half turns to be used, if you want them.

I tend to use coil attachment 1 on the diagram, as it is more central. You have to be careful attaching the left hand wire here as the screw is turning opposite to the wire wind. Hold it tight.

Yeah, I'd be the same as yourself, coil alignment 1 & 4GF, works best for me. In my earlier post, i was ending up with 5GF, too much...

I found when i used coil alignment 2, as the screw tightened, it was hard to stop the left-hand most coil getting pulled around the terminal. Might be just a bit clumsy, but I find it easier to control winding round the inside first...

derra, Gryzor ,how often do you do dry burn ? Every 4-5 ml i do . Hitting battery button as long as coil getting red and finally wick goes on fire (PG is highly flammable btw ) that's what makes winding as clean as new

Couple different ways than above...

Mostly every second day i give it a dry burn which would be after about 6ml.
Think i snapped a wire once or twice before, just made another

Read this before..

''The amount of crusting depends on what's in the flavouring added to the juice. I think there is some sort of sugar content, like ethyl maltol, that is the culprit.
If you want to waste some juice in the interests of science, put a small amount in a teaspoon and hold it over a gas flame. You will find a greater or smaller amount of burnt residue. This is from the flavouring. If you try the same experiment with pure PG or pure VG, they will burn but leave no residue. ''

I only dry burn when changing flavours, every three or four days (~10ml)....i'll pour boiling water over the wick to clean off the remaining juice. Then dry burn till the wick is clean. If it's really caked, i'll agitate the coils to remove the caked stuff, never seen the wick catch fire though...never had a coil actually fail either...

Got a Box Mod today with 3.7,4.2 and 5 v options regulated.
Have it on 4.2v @ 2.4 Ohms = 7.35 watts at the moment.
Vaping Liqua Tobacco juice at the moment from TBS @ 6mg
Will play around to find a preferred wattage but so far so good and nice to have different options from the 3.4 eGo.

I would say you stopping too soon then I don't use water to clean it at all -- no need - fire will clean it better then water can do ( well, may be you have to dry burn it more often

Just done it there now and it caught fire @ 5v :eek:

What way do you do it Alec,
A few secs on high voltage then drop it and fire it up again?

Or once it catches fire that is enough?

Congratulations Derek, it is always nice to get a new toy
I 'd like to get Darwin mod ( too expensive though )

U can set desirable power(watts) with this mod -- device will do the rest (check resistance and apply proper voltage to get this power)

I think so , you won't get any fire if it is already clean anyway ?

Cheers Alec and it probably won't be the last !
Yes i've read about the Darwin before but bit expensive alright.
We go halves on one and i take it for the first six months

I was washing the wick with water then firing it up with the eGo but after reading your post i won't be doing that again. A quick blast at 5v will do the trick. Was looking for this earlier when replying but could not find it..

''I start mine off on 5v to get the worst off, then when the coil is starting to glow mostly orange, I switch to 3.5v on a Tornado and pulse it until the whole coil is glowing orange, the smoke has died off and the wick inside the coil is starting to look whiteish again''

Drip Tip adapters are available again from Vapor Age.

Got the 701 to 510 adapter this morning and fits the Bulli perfectly.
Well worth getting to have another option.

Hear anything about these Alec?

Can you still use the white cartridge piece with this derra, or does it just turn the bulli into a dripper??
