New Atomizer Prototype

[jacko]

OK I got my 5 battery powered soldering tips in:

Peliminary test:
I took one tip and dipped it in ejuice, I then connected it to a 18350 battery. It took 1.5 seconds before vapor was produced! Very encouraging. I am getting the same ohm resistance as my 901 atty, 3.4! Getting better all the time. I will try and post a video. More to follow...

WOW... that is fantastic! This is sounding promising for sure. Good job Dan.

Been busy but found some time tonight to experiment! I made a new coil (spiraled differently this time) and it seems to be holding up.

I was trying to open more bulbs but I think I just don't have the right glass scoring tools. But I tried anyway, and this time wrapped Nichrome tightly around it on the score mark. It didn't quite break like I wanted it to... it just started melting

It's still going... I'm curious to see where this will go. For my next experiment I think I will lay a bulb down horizontally, with one end laying on a flat piece of Nichrome. I'm hoping it will just "slice" a hole open on one end as the bulb sinks through it, pulled by gravity.

Excellent!

i didnt read all of the posts, but wouldnt.. once it heated up.. it take a while to cool down also? and it would just be vaporising liquid meanwhile.

I don't usually post in this section, because my hands are waaaay too big to mess with nichrome wire (tried it, just got frustrated - I can't tie flies either). I had a slightly different idea that I was experimenting with, but ran across a part that may be the ticket for you guys.

SunRod 1/8" and 4mm Cartridge Heaters from Sun Electric Heater

They aren't cheap at $32.05 per unit, but they would probably last forever. 1/8" in nominal diameter x 1/2 in length would be an excellent size, and would fit nicely in several of the sketches I've seen in the thread.

As I said, I'm pursuing a different direction, but good luck. I'll keep monitoring the progress here, and if someone wants to build an atty from this using an 801 connector, I would be happy to test it! Just don't give up, and keep this thread alive with your progress.

Great work, guys!!

Everybody loves the fact they use them on the space station and have a 10 year or some other wild guarantee but some of our electrical experts determined long ago the math on these things will not work for us.

Not sure why the math won't work, but I think these may be worth trying - of course I'm no expert. Sometimes breakthroughs occur just because someone doesn't know he can't do something.

why not have the glass tube placed inside and the top touching a thin plate of metal that is fully over the glass making a good seal. that way the glass heats the plate. no liquid contact to the glass. plus no build up of crap after liquid has been used up.... no gunk no mess... a simple rub from a towl on the plate and its good to go. The glas should heat the metal plate no problem.

Hey, I like the batt soldering tips too!!

Maybe you could wrap that with the bridge mesh in direct contact and see if that gives better surface area, heating and vaping.

Then, the only issue would be making sure it stays gunk free to maintain the heat conductivity but no worries on this frying too easy.

 

[jacko]

Yea, I think this would almost be a direct replacement for what we have.... the heating element will never contact liquid, or other crap, and the surface would just need a wipe like a soldering iron...--- except that an iron is contacting solder, and these would only be contacting some VG/PG and some alc. and nic. juice...
Sounds great. If I didn't have to get 5 of these things (they tack on a charge if you purchase less than $25) I would get one or two to play with.
Anyone want to share some of the cost?

Dan seems lightyears ahead of us.

I would also add that you can get tiny pyrex pipetts, if that helps.

Someone mentioned quartz and I have been running gedankin (mind) experiments on quartz for a couple of weeks now.

I wonder how these would work as an electrode:

Saint-Gobain Quartz - - - Rods

I have also been toying with carbon and graphite as in this:

YouTube - How to Make a Graphite Igniter

But I would have to know the chemical content of that smoke coming off it...

Ok as promised here is a test run of one of the tips I got in. The first test mention above I did, only took 1.5 secs to heat up as I was directly touching the freshly charged battery. This test I recorded took 4.5 seconds before it heated enough to produce smoke, using my 18350 pipe battery I have been vaping with this morning. Well here is the video:

Ok guys, more to follow...

I would guess the next questions/steps would be a 6 volt and 7.4 volt test to see if that would get the heat up faster and produce that "burst" like vapor you get from a fresh atty.

Great WIP though. This is like the IC of attys

The glass heats up and cools down pretty quick, I don't think this would be too much of an issue.

Cartidge heaters

Too bad they're so expensive. We need to develop our own, which I think is doable, given that theirs is just a fancy housing for the Nichrome coils inside.

Ok here is what is inside of these soldering tips:

That look strangely familiar.

Nice work Dan.

 

[roadkilldeluxe]

Very nice! What gage does it appear to be? And how are the legs attached--it looks as though the coil might be crimped into them?

Thanks for the autopsy, Dan!

 

[Bubo]

Dan, you continue to amaze me.. (I read your 'profile' too - we'll have to compare telescopes one of these days... )

My question, in addition to what gage, is how long is the nichrome?
I guess seeings that I'm posting, I should ask if in picture #1, the bottom leg - it goes all the way through the coil? The 'wicking thing' is an insulator?

They appear to be spot welded, if I had to guess I would say 36 or 34

I use a Celestron NexStar 114 GT

36 or 34 I would guess, again guessing I would say 1"-1.5". The design is such that one leg goes all the way through, a fiberglass sheath it then placed over it and the nichrome is wound around that as an anti grounding barrier. The other leg is attached to the nichrome. Both ends of the nichrome look like they are spot welded. I will try and get a better picture tomarrow of the attachment point. I will be looking at the construct for the ceramic housing tomarrow also.
Here is my prototype:

Just to go totally off topic...
I have the Orion StarMax 127mm Equatorial Mak-Cass Telescope... The GoTo stuff showed up on the market just as I bought mine, and haven't saved enough to get one!
