My "Holey Crap it works" bbox mod

[SmokinScott]

Here's my first mod. It's over-engineered, but part of this project was as much experimenting with battery electronics as it was making a truly personal vaporizer. When I finally got it all soldered down and tested it, I said "Whole crap! it works!". So, I call it the holey crap.

There are two LED's, the first is activated with the kill switch (activated in this pic), the second is activated with the main, along with the attomizer.

Here are the guts. There are three parallel circuits going on here.

POS - KILL - LED1 - GROUND
POS - KILL - MAIN - ATTY - GROUND
POS - KILL - MAIN - LED2 - GROUND

Key:
POS comes from the positive side of the battery
KILL is the kill switch
MAIN is the main switch that turns on power to the atty.
GROUND goes back to the negative side of the battery. All leads go back to ground, to complete the circuit.

The grey stuff under the atty is Mighty Putty. I figured on making a tube for the atty to glide in, that way I could change the atty without taking the cover off. I cut a piece of celephane to wrap the battery and hooked it up the the connecter. Then rolled out the putty, made a strip out of it and squished the battery on top of it. Removed the battery for it to cure for 24 hours.

Unfortunately while this worked out ok for the atty, the battery connecter (Thanks Nerf!) didn't get glued to the putty. Oh well. In hind sight, I should have just used an exterior battery mount and used regular epoxy glue like I did for the kill switch.

Thanks to all the moders that came before me. Special thanks to Kinabaloo, Nerf, and Framitz for helping with circuitry advice!

HEY! Another new modder. And this one has improv skills. Way to go. My first mod was nowhere near this pretty, and I still don't have blinging leds in mine. Don't sell yourself short, SS. You had an ambitious plan and you saw it through. Keep rockin' the vape. You've got promise.

It's always great to hear of a successful build - especially a first one

A bi-color LED (2 LEDs in one) would be a nice improvement to consider.

Just drop this in as was just looking at these ...

This type os switch is really cool; they are used on elevators and such. 22mm diameter.
Rated for only 50mA at 24v though, so would be like using a tactile switch (opinons vary); could be used with a FET or mini relay though; FET better as relays are part mechanical and wear out; an electronic relay is an expensive alternative to a FET that could also be used; in these ways the button takes low power only and the atty gets the full whack.

Nicely done, Scott!

Great job Scott !!!
