Replacement for nichrome coil...

[jxmiller]

OK, I'm a little confused after reading the bulk of this thread. Are these actual ceramic heating elements or ceramic encased nicrome heating elements? From the figures concerning the resistance change it could be assumed that this is actual ceramic type heating, however the product of gaining resistance with higher temp could be achieved by adding a themistor to the heater.

If this is an actual ceramic heater I would be interested to know what is being added to the ceramic to lower the voltage requirement. From my experimentation in my previous thread, I found that higher voltage is required to allow the electrical jump across the ceramic material.

Also, I came across this tonight. There is a company already selling a ceramic vaporizer, though I believe the product intended for vaporizing is a schedule one substance....

Other thoughts:
Looking at some of the atty designs, not to say I can come up with a better idea or to flame anyone as all the designs look great, but comparing them to what has been commercially made it looks like no one is taking into consideration choked flow venturi. That is from what I can tell, the commercial atties are designed with choked flow around the heater in order to utilize the "venturi effect" to help draw fluid towards the core of the atomizer. Food for thought.

I just want to say you seem to post good thoughtful information.

It seems everyone is coming up with a different slant on ideas. Mine are modular (not going to do it any other way period) and The wetting method I am going to use is the "soak and drain" method. The juice Box already uses this, I own one and can attest to its ability to work extremely well. With this particular heating element, I would use the same method. The soak method allows for much larger reservoirs to be contained within the mod, eliminates flooding, dramatically reduces maintenance, allows for changing flavors easily.. and probably more. The only downside is that the mod becomes larger (box mod).

Regarding the soak method on the heating elements we are working with here, I would first try without any wick (hope that works well). If that works well I will also try wrapping some of that silica fire wick directly around the element to reduce pumping frequency. Hopefully that will work better and not start burning the wick. Over time the wick will need to be changed but with this type of element there is no "uncoiling" so that should be fairly easy to do.

From my discussions with the manufacturer, I'm pretty certain we are talking about the same type of ceramic heater, but these heaters are smaller than the ceramic heaters I have seen in the vaporizers that one uses with herbal materials. We won't know how well they work until we actually have them in hand, but they will fit in the same ceramic cup used in a BE112 (801) atomizer, and the tip should reach the same height as the bridge in said atomizer.

I definitely agree that airflow and juice feed need to be part of an atomizer design, but at this stage we are just trying to find a suitable heat source to replace the nichrome coil. If the heater proves to be suitable, then we can begin to design an atomizer around it.

I just finished chatting with my Chinese supplier. He was very embarrassed to admit that they found the package in their warehouse. Apparently, something in the shipping paperwork hadn't been specified properly, and the people in the shipping department didn't know what to do with it.

In any case, he tells me the package will go out today via Federal Express International. It should arrive no later than Monday, and perhaps on Saturday. I will send out the heaters to everyone who has submitted Paypal funds as soon as I receive the package from China (the envelopes are ready to go), and if there are any left, I will ask if there are any more takers.

I've received a number of requests for specs on the heaters. I'm pretty sure this was covered earlier in the thread, but I'll repost exactly what was ordered:

Diameter: 3.8mm (4.1mm where the leads attach at the bottom)
Total length: 12mm
Length of heating area: 4mm
Length of non-heated tip: 4mm
Length of non-heated base: 4mm
Optimal Surface temperature: 200C
Voltage: 3.7v
Ohms: 2-3 ohms, most are closer to 2 ohms
70mm sheathed leads

Here is the photo he sent me before they were packaged up:

At this point I have 7 heaters that have been paid for, and I plan to keep one for myself, so there are still two available. I prefer to send them out one per tester, so I will prioritize new requests over requests for more than one heater. If there are any heaters that haven't been prepaid when the package arrives, I'll send PMs to those that have ordered, and the first to send the Paypals will get the heaters.

Thanks,

This stuff sounds cool but check the MSDS sheet - it discusses irritation of upper respiratory tissues. It doesn't mean it wouldn't be suitable once it was fired, but it's worth checking with the manufacturer to make certain. It would be great for firing the holders the way you drew them out, complete with the air intake channels. I look forward to your reporting how it works!

That's for the unfired stuff, and the dust that is created when machining it. Too bad we can't get them glazed. Or can we?!?!

JXMILLER - Sorry the only thing I can tell you... is no one on this forum has even come close to this idea. (or least wrote about it in the forum) I think good enough I may try to patent & sell them soon. All I can tell you it won't be as small as the joye 510.. but it will be a manageable size & deliver unbeatable performance.

I suppose you don't want to give out any information on this long lasting atomizer solution?

Yo Qm4k

I got your msg,, but Im givin up on all this,, If anyone needs somethig made of glass call me..

other wise , , Im almost 3 months in and still have not burnt out my first 2 attys,, so I think the 7 xtras I have will keep me smokin for a long time..

I actually find my self not even vapein that much any more I love it.. its there when I want it but not so often..

Good luck to you guys,, once you figure it out Im the kinda guy that will still want one for my collection heheh..

 

[Quit4myKids]

Congratulations on finding something that works for you. I hope we have as much luck here, and can work the heater into a viable atomizer rebuild (or something).

Quit for my kids i',m interesated in one just let me know how to contact you.

 

[Quit4myKids]

I believe all the heaters have been spoken for, but I'm waiting on Paypal payments on two of them still. The individuals have been PMed, and if I don't have a payment by the time the heaters arrive on Monday I will send out PMs to the waiting list (there is only one person on the waiting list right now).

Nilles, if you want to be #2 on the list, send me a PM. I tried to send you one, but you are blocking PMs.

Thanks,

Good news about them finding the package at their warehouse. I was getting worried something was getting fishy, as ive literally never had a single package ever "get lost in the mail" in my entire life and ive sent/received thousands of packages of every size and nature of content imagineable. Theres always a reason why it never arrives, and its never because it simply gets lost.


Let us all know when they arrive bud, and your first impressions if any!

I have a rough test unit ready. I am waiting on some silica fire wick for regular versions but the housing I have made is modular such that any atomizer will plug in. What I am worrying about with this one is if the wires are replaceable if they are cut too short and things like that. I suppose some solder and a wire extension could be done if something like that happens.

I am wondering if this unit is liquid proof as my design will pump and submerge heaters thereby soaking them prior to use. I can test in a different manner if they are not liquid proof, would be good to know though. I am hoping this was already addressed. If not I suppose some solder could work to seal it off?

Alright can't wait.

Heaters arrived, and went out already to everyone who sent me a PayPal. I have two left, and will put it up for grabs again if I don't receive a PayPal from the remaining two people by this evening (4:45 from the time of this post), I will post again and make them available for whoever wants them.

Thanks,

woooooooot, cool cool cool.

 

[Quit4myKids]

Ok, I didn't get Paypal payments for the last two heaters, so the first two people that commit to the paypal payment of $28 (more for non-US addresses) each can have them.

Thanks,

Quit4myKids

 

[Jason365]

Awesome... I can wait to see what you guys can do with this. I hope some of you can just dive right in. Dont forget the pics.

 

[Spork!]

Can I commit to paypal now, or are they gone?

 

[SurfVortex]

I'll take the last one,if it's available. I PM'd you.

 

[jxmiller]

Got mine, I will test it in open air after I read though the posts here again to make sure I did not miss anything. I will report back after I do that. I need to get some stuff done .. kid needs bath and put to beed, still need to eat.... so don't sit around hitting refresh to see what I get off this thing.

Thanks, Quit4MyKids.. I feel like a little kid

I am actually very excited to hear what people findings are with these little heaters. Been following this thread for a while. Now time to hear what the results are.
Fingers crossed a new solution comes out of this.

 

[jxmiller]

Open air initial test:
***Open Air test... this means it will give different results in different conditions. Open air negates many factors, read on with this in mind.

Well it produces vapor. Going to try to get a black background and take a video.

I only tested it a few times, here are my initial observations.

Seemed to have a warm up period of about 1.5 seconds before I was able to see any vapor.

It produced a decent amount of vapor. Without it being inside a housing and having air passed across it.. hard to say.

Based on the warm up period, and the fact that air has to go across it, I would say that it needs to be wrapped inside an absorbent heat resistant material so that the air passing across it does not cool it down too much.

Seems to be able to vaporize 1 drop of liquid in about 15 seconds. It also stays hot for a period of time after no power is present which means it would continue to vaporize afterward.

What I conclude:

Does not heat up fast enough. Further testing required.

Ideal testing situation:

In a housing with similar conditions to conventional atomizers. Needs to be wrapped in a heat resistant material. Silica Rope for instance.

Since this seems to stay hot (and vaporize) for an amount of time something about the feed design might needs to be changed. This may not be an issue if the silica rope (or whatever material) and airflow cool it down sufficiently.

Other:
Muhahahahahahahaha. So fun. Sorry I only had time to do a quick dry air run and post this. I will plug it in later after I take care of some stuffs.
