look, no kanthal!... need advice...

[nelson996]

so you can create vapour without kanthal, but what are the deciding factors that could make this method work??? need some advice from those in the know please!!!

i have access to a machine shop, but i don't own a bench power supply, so even though i can make it, i can't do any proper testing in regards to power.

i left this test piece 'vaping' for over a minute using a 3.6v battery pack, didn't appear to be any burning, and the TH was emmense (probably because i was testing it with some old 36mg!!!)

gonna make an atty like this up eventually, but need some help, advice or constructive criticism please!!! is it worth me trying....?

thanks

It seems like as you can't regulate the resistance of the mesh you are stuck controlling the power input. If it is just a a batt wired straight up naked and using just firing time to regulate, it's probably quite a strain on the batt, especially the protection circuitry.

 

[nelson996]

so it's either a case of regulating the power supply, or could i try to alter the size of the 'bridge' (mesh exposed beyond the contacts) to get a compromised(?) outcome???

if there was some way to make this work, all you would need to replace would be the mesh itself. i presume it's gonna be hours of experimentation.....

we all want something that's reasonably easy to make and maintain, with the minimum of skills and resources needed!!! but i don't think it's gonna be that easy!!

thanks asdaq

More mesh would give more resistance, but there isn't a good way to standardize it like a wire of known gauge. Electricity takes the shortest path and it would be near impossible to track down the path in the mesh. A ballpark figure based on the resistance of one single wire in the mesh plus a sizable percentage 'fudge factor' for all the times there is a better or worse connection in the mesh intersections.

Much easier to control the power.

Looks very interesting nelson996. Pailpoe has been doing some amazing work here. I'll keep watching.

I finish my complete mod with a ULRA ato and power regulation this week.
It will be

thanks asdaq, as i said, i have the resources to make the atty, but not to test it with a power source, and to be honest wouldn't know where to start or what to look for!!! i understand the limitations of the basic design coupled with 'uncontrolled' batteries. my electronics skills are currently very limited!! definitely willing to learn but it's knowing from which angle to approach it. i suppose i would need something that would monitor voltage/current and adjust accordingly? i presume it's similar to what pailpoe is doing? should i persevere or......! i'm just trying to make something that could be powered by a puck or similar, something that everyone could have a go at making and not be too expensive. sorry, i'm hoping for a push in the right direction!!

are you using nichrome wire cloth? they do make it, McMaster sells it
(find under 'nickel wire cloth' at McMaster-Carr)

 

[nelson996]

definitely an option to consider, but not at this stage, it's very expensive!!! need to discover a way of powering the atty properly before any 'upgrades' can be investigated!!

You need a power converter to drive this ato at low voltage and high current.
