Automatic box mod with charging stand

[Ralph Hilton]

This is a bit of a rough prototype.
Here is the charging stand which uses a standard 510 passthrough with the battery removed:

The insides - a 14500 battery and a mosfet board with an op amp for amplification.
It is currently fittted with a KR808D-1. The 901 mouthpiece has a small sensor on it to activate the atty when the sensor touches the lips.

This shows the sensor better:

And here is the box sitting on the charger angled to minimize flooding:

Good job. Is there a way to charge it when on the move? Other than changing battery?

Wow you spent some time on that puppy.
Nice idea using the case for the ground connection.
Those 18650's last forever. Toss it on at night and your good to go for the next day. Good job Ralph.

Edit: Oops not 18650. Oh well should still last quite a while.

Is that all copper? Or is it brass. I see it is soldered so must be one of those 2. If it's copper then some major $ invested there.

Joker - not at the moment, this one is intended for home use.
Charged - its just a 14500 in this one. I have it positioned so that I just put the unit on the stand whenever I'm not using it so it stays at almost full charge all the time.
Its brass (lead free) - only €6 or so worth.

I like the whole idea! I might use it in the future with your permission?

Sure, go ahead. If you make your fortune with it don't forget me

Lol...Yea right. You'll be the second person to know!

Here it is in action (I made it to show someone the vapor from a cartomizer)

You know, I have sheets and sheets of copper, brass, and nickel, each in several different gauges. I've considered making something like this (just the box, not the stand), but haven't got around to it yet (I have silver sheet as well, but I reeeeeeally don't think I'll be building a silver mod, KWIM?).

Maybe I'll break out the torch next weekend and give it a go. I'm thinking something "steampunk-ish"...maybe do a bit of electroetching for the hell of it.
