Hello, I'm Jamma.. Long time lurker, first time poster (not counting the fluff they made me post so I would get posting privileges). Unfortunately I won't contribute hugely innovative ideas just yet, just a step by step "guide" of sorts..
First, deciding features. I wanted a big battery, ability to charge it while using it, something that will last, and preferably cheap!
To keep cost down, I decided to use chargers I already have, and sketched a diagram like this:
The battery switch is NC (normally connected) to the charger, and NO (normally open) to the atty. This means the charger is disconnected while vaping - simple way to use it safely with any li-ion charger.
With that done, time to choose components. This by far the most time consuming and challenging part for me.
This box is Hammond 1593DBK measuring 114mm*36mm*25mm. Turned out to be very easy to work with thanks to the detachable end panels. (battery is 18650)
510 atty connector,
5.5mm/2.1mm DC jack and plug,
Omron SS-5GL 4A@8VDC ON-(ON) microswitch - I chose a microswitch for their exceptional size/rating ratio and life expectancy,
Taiway 500-SSP-1-S1M1QE 6A@28VDC for master on/off,
and a pretty purple button for the switch - salvaged from a printer.
The hardest part is over, on to assembly.
Deciding where to place the button by what feels the most natural. I prefer to use my thumb, so this seems perfect. (And yeah, the floor is my favorite workbench!)
Drilling the hole.
Attaching the button. First glue, then epoxy putty to secure it.

Deciding where to put everything.
Hole in the back panel for the DC connector.
Middle panel (positive battery connector) hole for cables.
Square hole for main on/off. Dremel comes in handy!
And a final hole in the front panel, for the atty connector.
DC jack and battery '-' attached to back panel. Using blue wire as gnd and red for positive. As per the diagram, their '-' are connected. Gnd goes to the master on/off before continuing to the atty.
Marking down where to put the panel for battery '+'.
Gluing the master on/off and batt + panel.
.. and securing panel with epoxy putty.
Soldering blue wire to atty connector gnd,
Atty connector-pos to switch NO,
Battery positive to switch COM (common),
DC positive to switch NC,
Inserting the panel and gluing the switch in place.
One way to connect the cable to a charger... This one outputs 1 amp (*2)
Another potential way if you want to use the joye 510 charger.. That one only gives out 150mA though..
Fully assembled and plugged into charger.
And that's pretty much it.
