Power profiling. (A kick up the backside.)

[atomised]

I would like to be able to start a vape at high power, say for a few hundred mS, to heat the coil up quickly then drop way down to stop burning custards until the button is released.

I note some of the new controllers allow profiling like this but they're way too expensive and menuey/fiddly for me.

I see an analogue PCB with a couple of helitrims; one adjusts the "preheat" kick-up-the-backside time, the other just does vw/vv as normal. Very, very simple.

Has anything like this been done?

This seems like a great idea,have you any links to the controllers you mention as too expensive?

Errrr.... no! Sorry! What I'm talking about apparently is RVW and RVV. Real time variable wattage and voltage.

I thought the DNA30 or SX350 have it, but I'm wrong.

pbusardo talks about the evic supreme's RVW and RVV here

I was sure at least one other controller/device incorporates RVW but I'm darned if I can find it now. Must have dreamt it!

That 1st review must be the longest ever I've watched, and the only bit that interested me was the rvw/rvv and that was only a few minutes long.

Now I've seen the principle of it in action, I'll go hunt for any modders that have produced such a device as I reckon this would really pay dividends on quad/double coiled attys with really thick wires, as from my limited experience with 1mm wires the slow ramp up often meant that I'd forget to"preheat" them before starting to draw so resulting in half a lung full. Preheating some flavours could result in a tinge of burnt taste though, not sure if an electronic turbo boost would fix this either, I just would like to try it.

Thanks for the reply and any info you manage to find.

I'd hope that a variable "boost" time would enable you to tune out any burnt flavours. I only use single coils; with multiple coils I'm guessing you'd have to make sure they were fairly accurately matched.
I've just emailed the ever-helpful Rob at StealthVape. They do Murata analogue dc/dc converters which might be a good starting point at a reasonable price.

It takes me a little extra time to coil as I mount each coil on its own 1st to check the resistance, the 2 coils only need a little tweak to get them the exact same ohms. The only problem is if I drop the atty between mounting a coil after removing the 1st one as it could result in mounting the coils on the wrong sides to where they were made for

The process to achieve what your talking about is called voltage ramp. It allow a linear increase or decrease in voltage across a circuit. In theory it would allow a high start voltage ramping down to a preferred vaping voltage. Simple in principle, making it happen would take a good bit of research.

Don't I know it, I've spent several hours trawling forums and nobody seems interested in trying this ramping out
Now I know what the system is called, I'll have another look later at electronic supplier sites, though if they did a chip of this type it would probably only have a max output of a measly 3 amps(this seems to be what they call"high power")

Yep it's a tricky one, if I get some time over the next few days I'll have a look at the theory and report back, electrical engineering isn't really my strong point I'm more mechanical although I have covered a lot of the theory when I was at uni, it was a few years ago mind you.
