Volts vs Watts

[Katya]

Aaron, I still don't understand what you mean by "The variable you removed is the resistance of your attys by adding VW." How was it removed????

And I understand the concept that adding more functions creates a potential for more things going wrong, but really, it's just one more calculation--and the technology is here. Darwin was the first to introduce it, if I remember correctly, and now every mod coming from China offers it. It really isn't a big deal. Just a different chip. I'm sure that good people from ProVape are working on Version 3 as we speak. VW is here to stay because it makes everything easier for the end user, especially the new user with not much experience and/or knowledge of the Ohm's law and such things.

We're not sending a probe to Mars, mind you.

It is only removed in the sense that it is what people who love to tout how VV is old news and has no place anymore, all that kinda hype. No, this is not ground breaking tech. However, he asked to name one non "religious" reason why VV is better the VW. So I gave him a factual and scientific reason why. Everything argued about VV and VW is always nothing more then a matter of taste. I am a very firm believer that what the best device is, is the one that works for you. Even if it is a regulated 3.7v battery or whatever it is you like to use. vaping is all a matter of preference and there is no right or wrong when it comes to each persons preferences and what they like or want to use.

OK... Just for the sake of other readers of this thread who might be confused by your previous statement: Resistance readout has not been removed from VW devices in a physical sense. You can still check your atty's resistance on any VW device and you also have the option of using any VW device in the VV mode--if that's your preference.

Absolutely!

VW devices run VV mode also, VV only cannot run VW mode. With VW you get best of both worlds, with VV only you miss out on a key feature. New designs will have to incorporate VW or lose market share. It is simple.

Just because you seem so sure of this, even though there is no "better" then the other. Even though it's all personal opinion of what each person likes...

Physics is not just a matter of opinion. The simple fact is power is a function of voltage and resistance (P=V^2/R). We're just heating a wire, and that requires power, so power (duh) is better than voltage and resistance. Just like if we're talking about acceleration, we use acceleration (duh) instead of force and mass (F=ma).

If it doesn't really matter, there wouldn't be charts, calculator apps, math shortcuts (add to 2 resistance to approximate 8 watts), etc.

It makes sense to say "I generally prefer 8 watts", but it makes no sense to say "I generally prefer 4 volts".

But hey, if you prefer the more tedious and primitive way... Yeah, it's just a matter of opinion.

Because of the extra logic that must be on the PCB to perform VW output there will be more circuitry. This leads to a greater chance of failure/malfunction of the device.

First of all, most decent devices use MCUs. VW requires just a few additional instructions and clock cycles. There are no additional physical parts.

Second, if the PCB was actually assembled one component at a time, it would likely be much buggier than just using an off-the-shelf MCU. It is impractical for all but the simplest devices (e.g. no display).

Third, low-power components (e.g. logic gates) are very reliable. They rarely fail when operating within specs.

In fact, a VW device running in VW mode alone is already doing voltage regulation. In this sense, VW is a superset of VV. On devices such as the eVic or Darwin, the screen displays both the voltage and wattage simultaneously. There is no need for a VV mode at all.

New designs will have to incorporate VW or lose market share.

Yep, it'll happen, no matter how hard the VV proponents kick and scream.

It's like the progression from silient movies to flicks with sound, from black and white TV to color, from wired remote to wireless, from vinyl to CD. All over again. Who needs sound, color, or wireless, or digital audio, right? In each case, there were actually people who resists the new.

Good reply. Some in the VV fan club appear to be trying to say there really is no difference between a round peg and a square peg. Or there is no difference between using pencil and paper to determine the square root of 243859.45 or using a calculator.

At least with VW, you have one less variable.

There is only one variable that matters to me which is taste. I couldn't care less what the numbers come out to be. Whether my sweet spot is reached via VV or VW mode, I still tweak by pressing the same buttons to arrive at the same sweet spot so whatever number that comes out to be is irrelevant to me. Arriving at it via VV is just as easy as getting there in VW mode.

Heck if you want simplicity, go with a Twist. I couldn't even read the numbers on the dial, but was able to adjust my vape just fine. Why use your eyes to find your vape by reading numbers when you have a perfectly good tongue.

If removing one variable (resistance) makes no difference, as you stated above, why would you care to remove a different variable?

I guess you missed my smilie, I was just kidding about the closed loop molecular density sensor.
