The Wizard - Why not?

[SurfVortex]

Hey everyone! Awesome developments! Look what's happened!
Been under the weather for most of the last week, feeling WAY better now. During my convalescense(?), I had the opportunity to hook up a stock wiz to 4 more 1.2v AA batts (9 total) and HolyChit!!!!!!!!!!!!!! What a HUGE amount of fog !!!!!!!!! Still have not tried it with my homebrew-tabaccy-stank-juice......but,love is in the air...
Also, been drilling holes in my 1st(broken) wiz to mod with the lovely tubes.
As far as video review goes, I have not the technology nor temprament (read perfectionist tantrums) for such a thing. Besides, Dan's .... looks small enough in his vids, perhaps he is the better choice...

I can't believe I really did this.... but I just ordered a Wizard Stick. I was sitting here thinking how great the ecig is for on the go... but sitting around the house we should all have something with a LOT more horsepower, like a ..... Then I started looking at the butane based vaporizers, portable vaporizers etc and stumbled on the Wizard Stick thread. It's amazing but really comical at the same time, that a toy would work so well. I hope it works as well as everyone says, if it performs like I've seen it on the videos I cant imagine how awesome it must be to use. It looks ridiculous. Maybe I'll take it apart and remove the LED's...not sure if I really want a light up e-..... lol

This is a huge thread and I haven't had a chance to read all 65+ pages yet. I'd like to thank Charged and all the other folks who have contributed to this thread - your input is appreciated. I was just reading thru the clogging section and got skeered then I saw where the vinegar cleaned it out. Thank god! lol

Is anyone else still using their wizard stick to vape on? I saw a video on youtube of some dude attaching a gas mask to the end of it and letting it fill up with vape. I was laughing my ... off. Can't wait to get this toy e-.... / fog machine ... magic ... whatever it is.

C...did you see this...they took your PWM idea!! 8-o

LOL.... almost but not quite. It was just a matter of time. I actually mentioned this after 1st joining this forum on this thread last year. Closed loop is the way to go. Especially using the feed system we are trying to implemet. From the looks of the description I'm guessing it's not a closed loop control method. The hard part with closed loop will be getting the speed of response down so it can keep up with the feeding of the liquid. Processors are pretty quick but you can't beat analog when it comes to fast response. It looks like I better get on the SCHTIK and get to work on this before someone beats me to the punch.

Congrats on your wizard Bastage. You may wish to consider doing the high voltage mod or going with standard 1.5V alkaline batteries. I'll post the schematic for the high voltage mod later today for anyone that's interested in trying it. So far it's been working fine, actually better than fine.

Yeah, like I jut replied on there...the attys are the big problem. Thats why yours and Dans will take the prize.

I was thinking more along the lines of an AC adapter mod - but we'll see how it works and how long the batteries last for me.

Info overload

Dan sorry they didn't answer I also had this one listed in my favorites menu: TCS Micro Pumps It's in the UK as you can see but it is a tiny pump. I haven't tried to contact them as I've been working on a kinda worm drive type pump.

I have found those also, but the minimum ml/min is 150ml/min at 6vdc, I am wondering if a reducer would help as we really only need a flow rate of .5ml a min. Needs to be low so the heater can vaporize the fluid and not overwhelm it, in other words push past with out vaporizing.

As promised here is the schematic for the Wizard high voltage mod.

Few thoughts...

Reducing the voltage to the pump may reduce the flow (but the pump may refuse to work at a lower voltage).

Maybe split the flow from the pump so that the vast majority of the fluid is pumped back to the storage container but a small % (that's a very small % ..lol) goes onto the vaporizer.

 

[nicotime]

Could a 555 timer be used to dial in the pump activation in effect metering the flow? You can adjust the timing of a 555 right?

 

[nicotime]

Mine doesn't have a circuit board C...how am I gonna wire that up...even if I could figure it out??

 

[Dave_uk]

Could a 555 timer be used

The major issue is that the 'on' time would have to be so short it would probably be too short for the pump to start up (as the pump will have to overcome the pump resistance as well as its electrical)

100% on time = 150 ml/min, X % on time = .5ml.

The pump would only need to 'pump' for 1/300 of a min = 200ms

200ms is a lifetime in the world of electronics... but to try and get a pump to react at that speed may be asking a bit much.

Just for you nico.

I have been talking with Samuel Birgersson from Xaitech.com on the P200-LIQ pump found here:
http://www.xavitech.com/datasheets/rev/VP200_LIQ_rev2008-06-13.pdf

Here is what he had to say:
Our pumps minimum supply voltage is 3.2V.
So it would be possible from 3.2V up to 7.2V.
Do you need a constant flowrate of 5ml/min over the whole voltage area?
We can custom calibrate the pumps to keep a constant frequency thus a constant flowrate.
This is often used by customers which operates there devices on batteries.

So I asked for a flowrate of 5ml/min over a voltage range of 3.2-7.2 volts, we will see what he comes up with.

5ml/min

Which is 10 times greater than the required .5ml/min ?????

I'm exploring using an adjustable draw method for liquid delivery. Most e-cig users want some kind of draw feeling. Right now the wizard has a sealed chamber and relies on pressure from from a rubber air bladder to force the liquid up the heater tube. If you were to provide a small air hole in the liquid chamber along with a second air hole near the atomizing coil for (adjustable) fresh air entry. You may be able to accomplish that draw feeling and provide enough vacuum to pull the liquid through the tube.

I'm not sure if it will work but plan on giving it a try. Just some rambling thoughts again.

Yes but it is less than 150ml/min which I could control the 5ml easier than the 150ml But I think it is a bust at 1pcs costs 165€.

I am tempted to try the TCS Micro Pumps M100P2 for the simple fact that is only 43.00 GBP and according to the flow/pressure data it is only 1.6psi at 50ml/min, so restricting the flow might be possible. Since the pumg will be controlled by a second button, press for fluid. The user would have control over the pumping of the ejuice.

Now that is an interesting idea!

Thanks for all the info guys. I'm expecting to get my wizard this week. If I use it carefully, thin the liquid a bit, and keep it clean with vinegar etc how long do you think it will last? Just trying to decide if this thing will be usable on a semi regular basis without too much hassle. I guess I'll find out soon enough.
