Lol, I always took people using the word "clone" as a slang for bootleg but perhaps I was mistaken

As I mentioned there in the end I plan on ordering one, most of my go-to builds are Titanium so I'm confident I can get it to work. Voltage is the key to avoid PWM, some people it doesn't bother .. PWM annoys me but if I exactly dial-in the wattage or Joules I can minimize its effects. Since the Mod, I assume, is serial it should not pulse.

It's cheap in a good way. So we'll see, I'm waiting for batch (debugged) two or later this month. ;-)

I don't have an engineering background as I'm still an undergraduate student studying for eventual MBA-JD joint degree w/ history background, but I'd say I'm quick enough to understand an explanation of how these chips work. I haven't been able to find, less some schematics, press releases, & spec sheets, any solid 3rd party information as to what limits chips to certain wattages, and whether firmware updates to say the DNA200 chip would hypothetically allow for it to function at a higher wattage?

Would anyone be able to explain, and I don't need an entirely layman description, whether the batteries or the chip are what hold the wattage back from being say 250 or 300W? Is it the soldering slash material quality of the chip limiting its wattage rating, as I assume all electricity passes through slash over the chip directly? I would assume that the cylindrical Li-Ion is superior to the pouch Li-Po type for power but the Li-Po is better for those looking for a lighter mod?

I'm torn between three mods one of which I will buy within the coming week: Wismec Reuleaux RX200; Wismec Reuleaux DNA200; Vapor Shark DNA200. I've had terrible customer relations with the guys at Vapor Flask, which I realize are a separate entity from Vapor Shark and so is why I am willing to give Shark a try coupled with the physical mod itself having a nice rubberised finish. I suppose my question would be there whether anyone who owns an RX200 and has expertise on any level can checkout the board's manufacturing quality by eye alone, and how that would compare to the DNA200? Granted an equal manufacturing quality, I suppose it would go to preference, but if indeed the DNA200 chip is superior in manufacturing: which would people recommend based solely upon reliability & battery life, the Reuleaux or the Vapor Shark? I realize that I've packed quite a bit into a few extended questions, and so I might just create a separate thread for this but it seemed a relevant place to post it to start.

If I had to pick one DNA 200 Mod then I'd choose the Vapor Shark. It's small, properly set up out of the box, very comfortable, light and the only built-in 2A charging. I have a ton of DNA 200's. Now if you like uber high wattage builds and a little bulky then the Reuleaux DNA 200 Mod.

The reason for 75W ... 200W limits are primarily due to the limits of the batteries. Sure you can get a 2,000-7,000 mAh 30C or higher C (high Amperage) LiPo or better LiFePO4 and frankly many do but they vape on unregulated Mods.

To regulate it's a combination of higher voltage at higher amperage. After 20A~23A even the DNA 200 'pulses' through regulating voltage but in doing so through the DC-DC can provide 50A~55A. DC-DC https://en.m.wikipedia.org/wiki/DC-to-DC_converter

For unregulated Mods refer to Ohm's Law 250W requires 67A http://www.ohmslawcalculator.com/ohms-law-calculator

Now the DNA 200 could in theory deliver 250W but in a very small resistance range, as it is now appx 0.08-0.40 Ohm in Kanthal mode is the window for 200W.

Refer to the DNA 200 specs http://www.evolvapor.com/datasheet/dna200.pdf

Here is a really nice DX200-->DNA200 conversion that I stumbled across over on OpenPV.

LOL .. read it carefully, all you need is a Reuleaux DNA 200 Mod, a Reuleaux RX200, a DNA 200 Board, and a load of time .. BINGO you have 1 usable DNA 200.

I thought that's what this thread was about, but admittedly I haven't read all the posts.

It is and I'm sorry if I seemed even fractionally unappreciative. Thank you! What I thought was funny is they used the front of the expensive Mod, super glue, and out of two Mods ended up with one.

Oh, no doubt that has to be one of the most expensive routes to a functioning DNA 200 device...LOL  :/

But I must admit I'm kinda jealous of the black case.......

Is this project even worth anyones time? I could see if you were making some thing unique or some thing thats not readily available  out there.
These mods are available for purchase with a DNA 200, Why buy the cheep mod, a chip and do all this modding, to save 25 bucks?
Complete waste of time IMO. Just buy one with a DNA200 [smile]

Well i think the point of this whole thread is that the DNA200 version of the Reuleaux is in short supply because of the screens. The DX200 version is available more readily in some places. Some folks were wondering if you could convert the version with the lesser chip to a full blown DNA 200. I will definitely not be among those attempting this.

Dont think it is all about saving money either, it just looks much better in Black! and i have the DNA200 version...

I'm just gonna put this out there. For anyone who really wants a black DNA 200 Reuleaux my guess is that the reason for the single colour option was due to screen shortages. As soon as they're widely available again I bet Wismec will release the DNA 200 in a black shell.

Spray paint or a wrap...

Forget the time, you're splitting hairs on the retail side; $50 RX200 + $80 DNA 200. I ordered the black RX200... ;-)

I REALLY want the DNA200 version-but in the UK, it seems nobody can get them. I had one on preorder at vapegeek-and his vendor sent him the RX200's instead. He sent them straight back as he had payed for DNA200 Wismecs. 

If anyone knows where I can get one in the UK, I would be very, very happy if you could let me know where.
