PWM and YOU! (V8)

[LordDavon]

So, I have discussed this with Smokey (from UKV) (he has a new device coming out that calculates VRMS), as he has been schooling many of us on PWM devices. SenseField has a great video about this here:Dear Reviewers, You're Doing It Wrong - The ECD Meter - YouTube

...and, while he agrees that my calculations for figuring out the wattage are correct, I totally missed the point of the VRMS, and how that is the proper way to calculate the voltages for PWM devices.

So, Turtle, what you sent me was the correct way to calculate voltage for PWM devices. I was so focused on the wattage calculations, that I totally missed that point on voltages. Sorry buddy. You going to vape meet this weekend?

Wow...trippy. I just found that video today (don't recall how), and was going to ask if you'd seen it. GMTA!

I'm actually pretty embarrassed. The VRMS calculation is going to become pretty common for reviewers, and I was handed it back in June. Since I was so focused about wattage, the voltage completely escaped me.

I'm gonna try to get down there. Look forward to meeting you, LD.

Shoot, now I gotta go back and grasp the math on how your wattage calculation is still correct. I'll go through it, and if I still don't get it we'll sit down with pencil, paper, and lots of vapor.

Here is a clear and (somewhat) easy to follow explanation of V_rms, which I believe may have been written by Smokey (who convinced LD): http://ecdmeter.com/rms.html
