there are a lot of "herb vaporizers" that use fan forced air, have been around for years I think... nothing as compact as an ecig though
Yep, been busy with the kids, just got em back to school. One playing football (scored 2 touch downs last Fridays game), one in marching band, and one a Varsety Cheerleader. Friday night are now taken LOL
Didn't even know madvapes released a fan mad. Nice to see it finally got made and hopefully will help people with lung problems that refuse to quit smoking. Yeah, no "Reward" for me other than knowing the units might help someone.
Dan
No reward that I know of
I guess I should have seen this comming when a guy from madevapes took pictures of it at vapestock in Jun. My only satisfaction is somone that has a lung fuction problem and wont quit smoking picks one of these up and it helps them quit analogs!
Dan
That is a nice way of thinking about it. So Dan, I take it we won't be seeing too many development posts on Saturday mornings this fall?
Well for the average smoker that switched to ecigs with good lung capacity, it wont help very much except as a novelty. For someone that has COPD and refuses to quit smoking and cannot use ecigs cause it is too hard to inhale, they will benefit greatly from this.

Yeah, probably not

I know it's a late post but.... Credit where credit is due I followed this since day one and must say one of the reasons I enjoy ecf is because of the few people like you sir. I know you don't want credit for your idea since it has been dare i say cloned, but keep up the good work. thinking of others with out regard to getting anything in return is an honorable way to live and knowing it might help someone like my mom with copd made me want to say thanks!

It's more about the reality of life. He could have patented it and held onto it for 20 years with it never hitting the market, like soooo many products do. Patents have really hindered technology to a crawl because of this. But he wanted his invention out there to help people, and he has accomplished that. Granted, it would not cost them anything to give him credit, but they are (as Letterman once called nbc) money grubbing scum.
Its exactly what I was look for. Keep up good work. Hope u will finish it so we all can enjoy it.
I saw a little blower fan when I was looking at another project. The fan was actually a tiny Japanese "necktie fan". That got me wondering if any other new tiny blower-type fans were out there. I found some at Digi-key that were only 17mm and $14 I tried to link but for some reason is always shows here as "invalid request". Anyway it is part# UB3H3-700
Also, here is the manufacture's catalog. They have units as small as 8mm, but that comes with a significant drop in static pressure.

In general, a centrifugal type fan can create more pressure than a muffin-type fan of the same diameter. Note that if more pressure is needed, then you can obtain it by using two fans, and re-directing the air out of one unit, into the next one.

Yeah, been busy with life and have not had time to do anything ecig related. Got one going to college and the other two just started driving Yikes I am getting old! Thanks for the link, will have a look.
Here is a 12mm x 12mm x 3mm that can be ordered...

I know this is a very old thread, but I came across another technology that may be applicable. And, Dan, with your modeling and work with rapid prototyping, you may be able to implement something like this.
I am referring to a "Regenerative Blower", which is a type of blower that allows a much higher pressure than a simple fan. It is not a quick idea to get into your head, but essentially it is a centrifugal blower, that allows the air to make multiple passes through the same fan to increase pressure significantly. I tried to find an animation that would illustrate the principal, without success. But, here is one page that has some illustrations.

A related idea that I mentioned earlier in the thread, is that centrifugal fans can be stacked, to increase the pressure. However, the difference is that a regenerative fan only has one fan. The multiple passes all happen on that one fan. Here is that concept in an animation.

I am still thinking about this because I have never really found a solution to my own design goals, since I am not happy with the noise from the diaphragm pump I have used.
