Woodvil customizing/modifications

[Ian444]

Some modifications I have done, not that the Woodvil needs any improvement, so its more "customizing" I guess.

I wanted to reduce the total height so I removed some material from the brass fitting that holds the 510 connector, to make the atty sit closer to the top of the Woodvil. I guess its now a "LP" Woody.

The switch was removed and a delrin insert made up and installed holding a tiny clicky switch put in place, which turns on a mosfet (IRF6201) that has a 2.2 milliohm voltage drop at up to 15 amps (tested at work), which is a really good spec. But if I have a short circuit in my atty the mosfet may go open circuit or short circuit, not sure which, if it goes open I'll have to replace it, if it goes short circuit I'll have to replace it and the spring, I hope I don't find out. Anyway, the advantage of the mosfet is minimal voltage drop within the mod, and in theory makes this Woody good for coils down to at least 0.3 ohms. But since I use high ohm coils only, I am expecting better battery life.

Finally I removed the gloss finish and now it is an oiled finish, which I prefer, but I might try some Howards wax on it to get a bit more shine. Seems the oak doesn't polish up like my cocobolo 18490's.

I'm still working on a button cover, I can't find one that will fit at Reosmods, I think I'm going to have to make one ;-)

looks good man! I'm digging the LP Woodie.

Ah, a kindred spirit...I'm always so afraid to post my modifications for fear of the Reonaut pitch fork gang coming to my house in the middle of the night ...and to post a modded a woodvil, phew, that takes a pair, lol

Thanks for starting this (and taking the bullet) I'd like to add to this thread over the next little while if you don't mind?.

Reonauts only use the pitchforks to toss bread to the porkies, you're safe

 

[patrao_n]

I have never seen the reonaut pitchfork gang. I have always seen a welcoming group on every modification posted. If you modify your reo, please let us know. Some of us might be having the same urge you did. Remember the fuse mod? Others wanted to sub ohm as well. If it wasnt posted, I'm not sure rob would have come out this early with the kit.

You are correct I vape a 1 ish ohm coil if it wasn't for the sub ohm folks tossing themselves in the dirt it wouldn't have happened .
When customers told me they like to vape .4 I thought these guys were whacked in the head actually I still do think there a little wacky but who am I to judge .

Great! As if the demand for Woodvilles wasn't high enough already.. There goes my chances...
Looks great.

For sure, post away, it would be good to have all the Woodvil modifications in one place, no matter how involved or how minor.

Turbocad6 did some stunning work here

Glassgal put some nice touches on her Woodvil (and Grand) here

Love to know how she did that, I'm pretty sure she made it herself!

I read that Rob's getting some gold-plated beryllium-copper positive battery contacts for the Woodvils soon too, looking forward to that.

if this is the thread for customized/modified woodvil's then I should add my two woodvil's here. I did the first one by embedding the dna20 module into the side of the reo body and then made a brass cap for it. the second one I decided to build the dna30 into the mod from the inside so it adds nothing to the overall size. it's actually slightly slimmer than a stock woody because now there is no side button protrusion really loving these woodvils man don't want to carry anything else. I built a really killer 26650 bottom feeder with a 35 watt sx350 chip that is awesome, but even with that, I still just grab the woodvils first...

I just bought an oldschool VV woodvil from the classies yesterday that I will also convert when I get it. the vv woodvilles are really not that much taller than a regular woodvil, only about 1/4" taller so it will look very much like these really... so that'll make 3... I really want a few more and then I'll have a whole wood army of woodvils to keep me going

the second one with the chip built into the reo body is also waterproofed and fully submersible, I want to upgrade the first to also be waterproof but the second design is just so much more friendly to that. the first was built to be waterproof and I have made the firing button waterproof but making the up/down buttons waterproof has proven to be a challenge that I haven't completed yet. one thing is the wood bodies are much better with a dna than a metal body, the wood acts as a moisture absorber so in a way the wood protects the dna more than a metal body. I never really put up a how too because I doubt anyone is going to go doing any of this stuff but if anyone here wants any info on the guts of the second one or any other info on doing something like this I'd be happy to help where I can the dna inside of the reo is tight for sure but as you can see it will fit inside of the body and still have room for an 18650 and 10ml bottle if anyone wants to build something like this

the mosfet chip is awesome and that's probably one of the biggest things I like about the dna's is the electronic switching but I also like the regulation and the display that a module gives, do you have any pics of how you did the internals with the mosfet? curious to see where you put it why didn't you go for a regulated board, space? curious to see how small the mosfet setup is

 

[Ian444]

Thanks for posting that turbo, absolutely beautiful work! Will post some pics of the internals when I get back from work.

 

[Ian444]

I like mosfets for switching as they are quite reliable, I have used them in the past for other projects non-vape related, this IRF6201 mosfet has a really low on-resistance, and allows the use of any switch for the firing of the mod since only very low current will flow through the chosen switch. I've been wanting to fit a mosfet to a vape device for a while and the Woodvil was stripped so I gave it a go. I'm not so keen on regulated devices but have never used Provari or DNA boards. The cheaper Vamo/MVP mods I used prior to Reo's worked OK, but I found I preferred vaping without the switch-mode regulation. The DNA's and Provaris may work a lot better than the Vamo/MVP's but I am happy without regulation.

There is also a tiny surface-mount resistor soldered to the legs of the surface-mount mosfet, I can post a schematic if anyone's interested. So the pic is of 1st attempt, so far so good, its working very well. My only minor problem at this stage is the glue used to hold the 510 connector, originally it was hot glue by the looks, I don't have hot glue so I used Uhu Por which is used mainly for gluing foam, but can stick to a variety of materials and doesn't set hard like epoxy. I wanted to be able to remove the 510 again if necessary but the Uhu Por is not holding well enough, or I didn't use enough, probably the latter.

I really like the switch surround on your latest Woody Turbo, is that some kind of pressed washer, there is a name for it but I can't remember what it is. With a recessed switch like that you almost don't need the power on/off switch on a standard Woody. It looks really nice.

The mosfet is the tiny black thing with white wires attached to it, below the firing switch. If you click on the + symbol on the bottom of the pic, and then again, you'll get a higher res pic.

 

[Quigsworth]

I'd actually really appreciate a schematic of how you wire the IRF6201...I was pretty quick to jump all over using the trigger on the OKR chips when they splashed all over the batt mod thread a while back before it became the "all things DNA" batt mod thread (though it's interesting the OKR10's have made a comeback)

I don't mind a good regulated device but do have an appreciation of how much current these mosfets can switch/pass. I have my eye on a box with a height that will "just" hold an 18650 f/t (with about 5mm room for connectors) and width wise, the batt and this new 14mm square bottle that was found...if I can get a mosfet/tact to work...big time bonus!

 

[Ian444]

Here you go:

 

[Quigsworth]

Thanks Ian, wow that thing is tiny...kinda blows my mind you can pass 15A + through that...so to be sure is this it?

Invalid Request

Invalid request?...strange but the link still works

 

[Ian444]

Yep that's the one.

If you look at Fig 8 page 4 of the datasheet you can see in the DC operating conditions it will only do about 18 amps max, I tested it repeatedly at 15 amps, there was no detectable heat in the IC but the wires going to it got warm This is due to its extremely low resistance, it can't generate much heat.

The downside is, if there is a short in the mod, the chances are good that the mosfet will let go, either short circuit or open circuit, so you still need a fuse in case it goes short circuit. They are also quite susceptible to ESD damage, until they get soldered into the circuit. Once in-circuit, I've never had any problems with mosfets.

ETA - the upside is, it has only 0.0022 ohms (2.2 milliohms) resistance at up to 18A and never needs cleaning, and reliable for millions of cycles. I don't think there is any mechanical switch that comes close to this.

 

[turbocad6]

yeah man mosfets are cool. do you have any good diagrams for a touch circuit?

 

[Ian444]

Unfortunately no, I've never built one. If I come across one I'll definitely let you know.

 

[turbocad6]

I waterproofed my woodvil and decided to test it out tonight I love the electronics but hate how susceptible they are to juice damage, not going to be a problem any more I think

 

[MamaTried]

that was terrifying, tcad...
