Alright I know you are all really excited about this! Today I am going to show you how to build your very own DNA box mod. The cool thing about building your own box mod is that you can customize it any way you like.
As you will see in this video, I completed a swirl paint job on the exterior of the enclosure. This gives this DNA box mod a truly unique look that cannot be duplicated. I have also made a very detailed video on how to swirl paint so that you can attempt this as well.
Like I mentioned, this is a full DNA box mod which means it will have all the same features that you would expect from a DNA device. Currently all the DNA chips from Evolv are wired in the same fashion. So this video will be helpful for DNA 20, DNA 30, and DNA 40 projects.
Okay so let’s not waste any more time! Let’s get right to it. I will first show you all the components you will need to build this box mod.
What You Need
- EVOLV DNA Chip
- Hammonds 1590A
- Lipo Batteries
- Spring Loaded 510 Top Cap or Standard 510 Top Cap
- Tactile Switches
- Resettable Fuses
- 20 gauge Wire
- Soldering Iron
- Soldering Flux
- Heat Shrink
- Double Sided Tape
- 2 Part Epoxy
- Lexan Sheet
- VHT Night Shades
Alright so that’s everything you need, let’s get started!
Laying It All Out
For this DNA box mod, we will use the Hammond 1590a enclosure. Holes will need to be drilled for the 510 connector and the switches, but let’s first decide how we will place each component inside the enclosure.
Once we temporarily place the two Lipo batteries inside the enclosure, we can get a better idea of how much room we have to work with. We can now decide where to drill the holes for the 510 connector and 3 switches.
There is also a perfect location for the USB charger on the bottom of the 1590a enclosure. The USB charger will be accessible through the Lexan cover, so no holes need to be drilled at this time.
Wiring the DNA Chip
The largest gauge wire Evolv recommends for wiring the DNA chip is 20g wire. It is recommended to use high quality stranded copper wire. I did use solid core wire in this video, but I highly suggest using stranded wire. Stranded wire is more flexible and will make your life easier when routing the wires inside the enclosure.
What I like to do before soldering wires, is to first remove the onboard fire switch. The reason we want to remove this switch is because it takes up unnecessary space inside the enclosure. Since we will wire in our own fire switch, the onboard fire switch is not needed.
Now let’s move onto soldering wires to the DNA board. Again, please watch the above video for more detailed instructions.
Always pre-tin the wires before soldering and it is also good practice to use flux. I have a dedicated video that demonstrates how to properly use soldering flux. That video is titled “MOD TIPS #01 – What is Flux?”
Wiring the Tactile Switches
Once the DNA board is fully wired, we can move onto wiring the switches. These tactile switches will have a total of 4 legs, however we only need 2 of those legs.
Simply choose one of the pairs (there is 2 legs on each side) then remove the unwanted pair of legs. You can easily remove these legs but snipping them off. Then take the remaining pair and bend the legs down flat. This will allow the switches to fit inside the enclosure with the battery in place.
You can now solder one wire to each leg of the switch. Follow the previous procedure by pre-tinning and using flux. Another good practice is to apply heat shrink to all your connections. This will give you a cleaner look as well as protect your connections from shorting out on the enclosure.
These wires will eventually be connected to the DNA chip but we will get to that later.
Wiring the Lipo Batteries
Let me first start by saying that Lipo batteries can be very dangerous if not handled correctly. A failing Lipo battery can burst into flames and be catastrophic. However if used properly, Lipos are very efficient and have higher amp limits than standard 18650 batteries.
FindMyVapes, its owners, and its affiliates will not be held responsible or liable for any injuries, damages, or defects that may be caused by the improper use of these products. You are taking full responsibility of your actions and releasing FindMyVapes from all liabilities.
Each individual lipo pack is rated for 1200 mAH and will be wired in parallel. These 2 Lipo batteries will give us a total of 2400 mAH when wired in parallel. Simply take both positive wires and solder them together, then take both negative wires and solder them together as well.
You can now stick the 2 Lipo batteries together after wiring them in parallel. I prefer to use clear double sided tape to join each pack together. It provides a strong hold but does not add anything real thickness to the batteries.
Wiring the 510 Connector
At the time of filming this how to build a DNA box mod tutorial, there were not many options for aftermarket 510 connectors. So in this video I used a stainless steel top cap off an old mechanical tube mod.
Since this video however, there are much better 510 connector options for DIY modders. I would highly suggest looking into either the Fat Daddy Vapes 510 or the Varitube spring loaded 510 connectors. These are much better options than the one used in this video.
I have also made a dedicated video for these aftermarket 510 connectors. You can see this article titled, “MOD TIPS #03 – Fat Daddy vs Varitube Spring Loaded 510 Connectors.”
Lexan Front Cover
This new Lexan cover will replace the aluminum cover that came with the 1590a enclosure. This process is completely optional but I feel it gives our DNA box mod a really unique and modern look.
All you have to do is trace the stock aluminum cover onto the Lexan glass. Then carefully cut out the shape and drill holes for the screws and the USB charging port. There are a number of ways to cut Lexan but I decided to use a Dremel tool. Then I lightly sanded the edges to give it a smooth finish.
It’s Epoxy Time
So we have everything prepared for the final installation of all the components. But before doing the final wiring, you need to first mount all the switches and 510 connectors permanently to the enclosure.
The best adhesive to use for this process is epoxy. You may want to practice using epoxy because it can get messy if not properly planned out. This will give your components a very strong bond to the enclosure.
Almost Done! Final Steps
Now that you have everything in place, you can now secure the Lipo batteries into the enclosure. Again use some double sided tape to secure the batteries to the enclosure.
Start routing the wires on the DNA chip before sticking it to the batteries. This will make it easier for you to do the final soldering of wires. See the video for an example of how I routed wires.
So now that you have everything in place, you can now start soldering the wires together. When the wires are properly soldered together, you should have a fully functioning DNA box mod.
That’s it, you are done!
There are definitely a lot of steps to building your own DNA box mod but it is well worth it in the end. Don’t let these steps intimate you from building your own. It is actually a lot easier then it may seem.
Just take it slow and take your time. This video should give you a complete walk through for completing this project.
You might want to practice soldering if you have no previous electrical experience. The end result though, will be a completely custom and unique look. You will definitely have a mod that no one else will have.
Best of all, you can tell all your vape friends that you built it yourself!
