Hi everyone, I am new here, but have been vaping for over 2 years and thought I would show you the DNA40 I just made byway of an introduction to this great site. I'm going to the London & South East Vape meet
https://www.facebook.com/events/160388180798576 tonight are any of you coming along?
Here is my home made DNA40 box mod. My main priorities are compactness and quick battery swap without using tools and I have not been able to find an of the shelf box that suits so have made one from aluminium box-section as I had done in Jan 2014 for a DNA30 build. Since there is not enough room inside the box-section I had to remove a lot of metal from the side where the battery sits which took most of the time as I just have a Dremel and hand files. Also to fit the DNA40 board in I had to remove the fire switch and bridge it's negative PCB pads (it appeared to function with out this, but it formed part of the circuit). The battery is negative side up as it is connected to a piece of circuit board that the 510 bolts through and I don't like the vents pointing at my face. I do not make mods for other people because of my primitive tools I could not charge enough to make it worth my time.
Finished size (not inc 510): 75 mm x 38 mm x 22 mm

Boring bit, build details:
The build order was to cut, drill and whittle the box section, which took 4 days as I have to cut larger (21 mm) and then file to size (19.6 mm). Then epoxy the oversized back to the box section and after that has cured reinforce with L profile strips Heineken can along the long edges as there is not much surface area for the epoxy. At the same time I fit the guide strips inside the oversized battery cover. Once this is all cured I sand down with 60, 80 & 120 grit emery cloth on a flat bit of marble and finish with 600 grit wet & dry to get it all square and the right size.
Then it's the easy part, I soldered the wires to the switches and epoxied them in position. The 510 just bolts through a piece of circuit board the runs across the whole width at the top to which I later solder the hot-spring and negative power wire (I did not wire the ground/negative out separately as it is the same on this board). I soldered the power and 510 positive wires to the board before fitting. Then it's just fixing the screen and soldering the other ends of the wires, the positive to the 510 needs to have a bend in it to allow the spring loaded centre pin to work properly. Finally I used Sugru to secure the screen & board and built up blocks top and bottom to hold the door magnets and be a buffer against the battery. I may put a metal plate between these Sugru blocks to protect the board in case of venting, it does have a small vent hole in the bottom and the magnetic door would not allow any large pressure build up.
