What is PWM?

Pulse Width Modulation. A method for delivering power to your atty. Don't ask beyond this point. PWM was the rave at one time before people realized it sucked. But PWM can be good (as in the case of the Provari) but it gets a little hairy explaining Hz and all that stuff.

    I'll have to learn furniture building and create my own custom vape gear/juice aging cabinet. Then market them, make some real money and buy more gear and juice. Right now I can't imagine any other future path. ;)

    Your talking BK's language on the furniture and cabinet building , he's dam good at it , when he ain't cutting his fingers off ! :)

    I vaped about 3 tanks of Maple Eh in one of my 3.1's while I was in Nassau. When I got home, I decided to clean it, dry burn and re-wick.

    Here's a pic of the wick when I disassembled the 3.1. This is BEFORE any rinsing:

    It's amazing how clean Maple Eh vapes. The coil needed dry-burning, but Maple Eh rivals Heavenly Tobacco for the cleanest burning juice I've ever used.

    What is PWM?

    Pulse Width Modulation.... its the process in which a constant supply of electricity is turned on and off at a very rapid rate. By controlling the on time as compared to the off time, it makes the load ( coil) act as if it is recieving a constant but lower or higher voltage...

    for example, the crt style monitor ( the old glass ones) turn on and off at 60 times a second but "seem" to be on all the time.

    if the supply voltage is 10V with a 50% duty cycle ( 50% on 50% off) the apparent output voltage is 5 v...

    Okay, that's cool. And I actually thought of the CRTs reading your first paragraph. I've worked on computers many years from the software and hardware side. It's fascinating stuff. My former father-in-law worked for Bell Labs (later became AT&T) as an engineer. He taught me a lot about circuitry and engineering concepts. I don't remember most of the terminology, but a good bit of the concepts.

    Thanks for explaining!

    LA , how's the Huntsman 3.1 combo working for you ?

    It makes me like Huntsman more than I did before. More complex, but more subtle too. Or maybe just smoother. I'm more focused on how to get the most from each draw though. You know, without choking. Vast clouds! I usually mouth hit, then inhale. Much trickier to get it right on the 3.1.
