I like it but it's half-assed compared to the power a mech puts out.
How exactly do you exceed battery voltage with a mech?
That's right you don't.
Some flavors work better at different power ranges. See a few where the flavor profile changes, with different flavors becoming more or less prominent at different power levels. Nice to just change the power setting to find the taste you want now instead of swapping
coils.
Not to mention the volume + flavor you can get with multi-coil builds at higher than battery voltage.
a single 0.5ohm col at 30 W is not the same as 2 1ohm
coils with 15W each.
Never mind the limits on total power that you have when winding coils. You just cannot get the flexibility.
That said, I prefer mechanical too. I just don't discount the utility of a controllable boost circuit.
What would be cool is you mod with an option for several different boards.
A space to hold the board and a set of parts that convert the nice simple mechanical switch circuit into the configuration needed for a board.
If the board breaks, swap back to mechanical.
Don't want 40W, then get a 20W or 30W board.
If they latter have a higher power board, it's likely to be usable too.
You supply the parts needed except the board. User buys his board and wires it up.
You have no responsibility for the electronic used.
But, hey it's YOUR design too, so do what YOU want with it.
