What are the dimensions of that board. I will be making one next week with a charge chip and MOSFET although the chips I am using are much smaller ... Sot23-5 and so8
Cyber - its 18 x 46mm and 12mm high - ok for my clunky 18650 workhorse.
I haven't yet looked into components for an smd version.
Warp - soldering that size stuff isn't hard to learn - using a fine multicore solder and even a cheap 25 watt soldering iron it only takes half an hour of practice. With your obvious expertise in mechanical things I wonder why you balk at it?
One thing that makes it much harder is the use of lead free solder which has a high melting point.
Sometimes regulatory bodies have some strange ideas. Here in EU there isn't a regulation preventing the use of lead/tin solder in home projects or kits. Lead free solder is necessary in any connections where the solder could possibly be in the air stream one is inhaling. Of course I'm wouldn't advocate the use of lead/tin solder in areas where it is forbidden to do so even if it is much easier to use especially for a beginner.

Ralph - any way you could test your mosfet using the schematic that kender provided? I'd like to keep components to an absolute minimum necessary.
It might work with a higher value resistor but I don't recommend it. It could work with some contacts and not others. I'm 99.9% certain that the simpler circuit is unreliable.
Mosfets are not perfect devices so whenever I use them I make sure that the voltage applied to the gate is definitely on or off. The additional components are all cheap. Compared to the price of cigarettes what is $3?

I'm not where i can easily get components - I have to order them from Stateside. I also have to squeeze them AND a voltage regulator AND an atomizer connector into a single AA battery space.
I'm looking at either the mosfet circuit that kender showed, or a darlington pair like kinabaloo's schematic

Thanks Ralph,
I do know how to do it, it's just too many little joints in that picture.
I have a really cheap (and I mean cheap), soldering iron that works great.

Anyway, I will wait to see more members doing this mod and then I will get into it.
I have too many projects going on simultaneously to add one more right now.

Mnealtx - I'd need more details of what you are creating to make useful suggestions.
I'm making a serial nicostick and want to use a touch sensor instead of a contact switch
Does cereal sound better for you guys?
Since when are nuances of language such a big deal?
Serial=in series
Both correct...
Serial and parallel battery configurations
___
But there is also a serial port on older computers which is a totally different thing. Most people who have been around a few years understand the term "serial" as referring to the serial RS232 interface. "Series" is not the same as "serial".
Did you already realize we are in a e-cig forum?
Did you even take the time to look at the link I posted so you would see I am not making it up?
What use would you give to a serial port or interface for such application?, I can't wait to hear that one.
I have been around more years than the serial interface has.
IN SERIES battery connection is the SAME as SERIAL battery connection when speaking about battery connections, right?
That is the "jargon" we use in the forum regardless of it being correct or not. (and it is correct)
I know you love to argue Ralph, but come on!

I've got a cheap desk lamp at work from ODepot that has a touch sensitive switch on it. It has a low, medium and high setting too. The switch is contoured inside a 2" diameter base and about 1/2" in diameter. I think the lamp cost like $40.
Can't be too expensive to produce a switch like this. It is obviously not a moment switch, and that may be the tricky part.
Haha, didn't get to read the other posts while typing, but a RS232 Serial port/interface is in fact a series connection. Check the pin outs on the DB connectors. You also have a parallel port on your old computer too, for your printer.

anyone investigate these...
The EVERSWITCH Patented technology
kind of on the large side but might be able to gut it.
