As promised. Here is a tutorial for building a VV wood mod. Using a OKR-T 6 amp switching regulator, Voltage display and dual 18650 batteries. This one will be referencing back to the other tutorial I posted before for the Majority of the basic build. So If you have not read it (What the heck is wrong with you ) here is a link to that post.

It may Seem very large and complicated to some people. But if you give it a try I think you will be very happy with the performance.

Here is what we are building

Parts List needed

Went with Alder this time. Listed where I got the parts from.

Once again feel free to substitute for parts and tools on hand.

 

Mad Vapes

510 Connector

18650 Batteries 2 at least. Either Protected ICR’s or IMR’s

Voltage Display – Only if you want to mount a outside display on the mod. It can be monitored with a screw on display or multimeter. But it is much easier with it already on there.

Any type of switch you want. I liked the look of this rounded flush one and works great.

 

Vapoligy

(2) Pairs Battery Spring Plates – Battery Spring Plate
Radio shack

PCB- Printed Circuit Board They have a few get the one that has a mix of 2,3,none, and continous connections between holes they sell for around $2.50. Or if you are able to, make your own PCB.

Small magnets If needed. Once again so far I have not needed magnets to hold door on.
Digikey –

OkR-T Switching Regulator comes in 3,6, and 10 amp sizes. I ordered a 6 amp for this one and a 3 amp for another mod. Very happy with both. Batteries last a lot longer than linear regulators.

This is the resistor I used for my build based on the first schematic I seen. But it has been pointed out to me that this one is out of the specifications from the manufacturers datasheet. They recommend a 220 ohm resistor which will limit your max voltage to around 6 volts. Which is what I now recommend. So the 2nd link is for a 220 ohm.

Home Depot

1/4″x 1 1/2″ x 24″ Hobby Board – I went with the alder on this one.

3/4″ screen – once again you can use any scrap piece you already have.

20 to 22 gauge wire
Tools Needed Same as before See Previous Tut

Cuts needed – Hobby Board

(4) 4 1/4″ pieces look for interesting patterns and label front and back. Others label left and right.

(2) 2″ pieces label top and bottom

(1) 1 1/2″ Label Angle piece

3/4″ screen

(1) 1 1/2″ piece label support

(1) 1 1/4″ piece label U

(2) 3″ pieces label U

Once again feel free to substitute what you already have available for what is listed here.

This is where using a 220 ohm resistor instead of a 200 ohm will show different your top Volts will be Around 6

Hopefully I covered everything you need to make your own. But if you have any questions or see any safety concerns please fill free to post. Any and all Comments and or critiques are greatly appreciated. Also if you do make one please post a picture for me.

I find myself reaching for this one most of the days and take it everywhere. Depending on the MAh of the batteries it last me 2 to 3 days of continuous Vaping Bliss. (A Switching Regulator like the one used here is a lot more efficient than a Linear Regulator which wastes power in the form of heat so your batteries last longer).

Enjoy and Happy Vaping!

    Another crackin’ good tutorial. According to the tracker, my DNA20D should be here Wednesday; can’t wait to give it a go in one of your designs!

  2. Chad says

    Your tutorials rock!

  3. Ralph Tirella says

    how long did it take you?

  4. Sonar505 says

    I can usually knock one out on a weekend with the glue and poly drying times. If I have the materials gathered in front of me. Once you do the first one it becomes very easy.

  5. Amanda says

    That is so pretty! Very nice!

  6. Amanda says

    Have you done any others with other types of wood?

  7. GhOsT DoGg 79 says

    Agreed, that is an awesome job man!

  8. GhOsT DoGg 79 says

    Yes….have you done other woods, or made other ones?

  9. John "Shub" Fellhoelter says

    That is pretty slick. I might have a new DIY project in the near future.
    Don’t tell my wife

  10. Aaron says

    looks like a fun project.

  11. jimpo42 says

    Very nice tutorial again! I know you usually stain your boxes but there is a method for sealing them called CSA sealing which is pretty much sealing the wood with super glue. A lot of people I know use this to seal wood scales on straight razors. If you like the natural look of the wood it makes a very good waterproof seal and won’t discolor like a lot of the wood sealers will.

  12. michellebastin says

    Thanks I will have my hubby work on this πŸ™‚

  13. robowvape says

    another great in-depth tutorial, i wish i had access to the tools to do this, it would be a lot of fun and a great piece for a very modest price…

  14. Courtney says

    Beautiful mod! great tutorial!

  15. tiffjamesnjj says

    nicely done!
    think i might but this off to the side for a bit….
    maybe one day πŸ™‚

  16. Clawfield says

    Thanks I will be trying this later πŸ˜€

  17. The Crooked One says

    If Ionly had the time…

  18. morrinb says

    Awesome tutorial. Thanks for sharing!

  19. Johnathan Brown (Sepsis) says

    This is a great walkthrough. However, I also suggest you add two switches. one coming from the batteries directly as a master on/off. Then, I suggest wiring another one up from the voltage meter so that you can toggle between direct line in from the battery so you can see battery voltage, and the other side wired through the okr so you can see set voltage. Dunno if you’ll have enough room to fit it in the box though.

  20. Holden says

    Coolio.

  21. Flux83 says

    This is great I was wanting to build something like this. Thanks and great job.

    Thanks for taking the time to share this project. The pics make it easy to follow.

  23. Karla Lyle (MsV8PR) says

    I have always wanted to make my own VV Mod. i would love to try to make a bottom feeder. πŸ˜‰

  24. michellebastin says

    Ok so I showed this to my husband so he could build me one and he said that’s to much work I’ll just buy you one lol

  25. starlyte says

    Really nicely done, clearm and beautifully illustrated, so I thank you from the bottom of my heart. I really needed a such clear tutorial, to get things straight and this is excellent. 20/10m if I could πŸ˜‰

  26. Anthony says

    I have GOT to build one of these!

  27. bybees3 says

    Cool beans, man. Thanks for the info.

  28. bybees3 says

    Pretty cool. Have to try that sometime.

  29. BuzzBait_vapes says

    Very detailed and crystal clear tutorial, You convinced me to make one this weekend πŸ™‚
    Thanks for taking the time to put this up for us!

  30. Chuckss says

    Awesome guide, great attention to detail!

    How to Build A 5 Volt 510 Box Mod

  32. DubalYou says

    Total newb so this may have been asked/answered/explained but in case it hasn’t, I’m interested in building a 50watt mod of my own. I have ZERO comprehension of the science’s involved and very little experience with soldering and electronic reworking. Any chance poster/commentors could advise or direct me to what all I need to purchase? I assume with what SONAR has shared here, I can construct my device. I just, know NOT what component(s) I need to acquire…ANY/ALL help/advice is GREATLY appreciated! Thanks all!
