i believe i have a plan forming

[iuseaspork]

Boosted feeder. Might have enough room for on-board charging.

Cool plan

Looks quite good, a dna charger is about two thirds of that board and thinner.

I'm trying to get this booster to work, but I'm only getting a range of 4.5 to 4.9. Any ideas?

 

[asdaq]

What are your resistor and pot values and where are they connected? IIRC, that range reflects about 60k to about 150k between pins 3 and 4. If you want the top voltage higher than 5v, you have to go about it differently.

15k between 3&4.... 4.7k an 100k pot in series between ground and 3. The wiper and other side of pot are shorted together and to ground.

check your wiring/soldering

Ugh! ...I've built several buck mods with no problems. This one is frustrating me enough to make it a semi-mechanical mod. Been wanting one of those too. Want to use a low res MOSFET and 14 gauge house wire.

Gonna put the booster on the back burner.

Oh... And stainless Steele is a bear to drill even with titanium bits!

...and yes, one of my pins came loose while soldering. Had to reflow it back in place....crooked... Grr

Yeah, stainless is very hard to work with. Use Cobalt bits, medium speed, and high pressure to minimize work-hardening of the drilling surface.

i would swap atty and chip location.
but this is depending on, if your atty is capable of bottom feeding...

this way you can separate wet(atty/bottle) from dry(battery/board) area.

just a thought.

Good luck on that wiring!

So here is what I ended up with

Atty is modded from the top of a Chinese did. Running 1 ohm coil on it with a .4 v drop at the Atty.

This one isn't done, and I will change a lot if I make another. ...Till then, this is the best vape I've had.

I mainly want the air intake to be external as that's the only place it leaks from.
