Hello everyone,

I've been reading the forum for a while, but I haven't posted here before. I first tried vaping in 2009 with an e-cig from China (Ruyan). That was a miserable failure. I tried it again in 2010 with another "mall-kiosk" model with similarly disappointing results. In early 2011 I bought a Volcano Inferno e-cig and that was the first time I felt like the technology was mature enough to completely replace tobacco. Since then I've been vaping for almost 2 years on various devices and even built myself a VV mod using the OKR-T/6 regulator and the Denali design by Mamu.

Happy vaping!

Very nice! Care to share pics of your creation?

Having gotten fed up with the inadequacy of commercially-available mods and batteries, I decided to draw on my knowledge, skills, and resources acquired from my RC helicopter hobby to build a mod to rule them all. Fortunately, I was sitting on a couple 3s 2200mAh 15C packs that are no longer strong enough to fly on any of my birds so I did some research and designed a box-mod around one of them. The following is the result of a few weeks of technical research and sourcing components, as well as ~30 hours of labor.

My mod is based on the design of the Denali/Dena by the famous modder Mamu: Presenting Denali...

The wiring schematic is shown below. My box is a different shape and size, but the same wiring principles were used.



Features (indeed nearly identical to the original design):
- High efficiency 6A, 30W switching converter (OKR-T/6-W12-C)
- Input/output capacitors
- Stainless steel atty switch with clicky feel
- Master switch - on/off
- Display vaping volts - on/off
- Display total volts - on/off
- Finger adjustable voltage control knob
- 3.37 - 6.00 volt vaping range
- Uses an old, no-name 11.1V, 3s 2200mAh 15C LiPo (with about 100 flights on my 450)

Most of the electric components were sourced from digikey. Mainly, I had to go with different buttons/switches to accomodate the shape of my project box. I also bought the 1-6s Lipo voltage monitor from ebay and a "Shorty" 510 battery connector extender from madvapes. Other supplies needed I had in stock: various colors wiring in 20 and 24 AWG, heat-shrink tubing, liquid electrical tape, Steel-reinforced JB Weld epoxy, and QuickSteel epoxy putty.

The resulting mod is obviously huge, but vapes extremely consistent, has gobs of power and the battery lasts 6-7 days before needing another charge. On the other hand it is not very user-frienly, in that it requires a specialized charging setup (i.e. RC hobby-grade charger/balancer) and the battery needs to be removed from the box for charging.

Welcome to the forum! I have to say that's a slick looking build.

Welcome, and nice looking build you've got there.

wow thats some heavy duty mod. pretty nicely made.

 

[budynbuick]

Very nice.

Thanks, everyone. I think this mod's ultimate utility will be during the camping season this year. There's nothing more annoying than lugging around a charging setup and having to change/charge batteries all the time when I'm out in a tent in the middle of nowhere.

I added a few more pictures of the Big Boy mod to my albums
