    PWM and YOU! (V8)

    How about this example for power in a square wave (50% duty cycle): Take a 6 volt dc source and switch it once every second between two 2 ohm loads. The 6 volt source "sees" 2 ohms, pretty much all the time. Three amps going to one load for a second, 3 amps going to the other load for a...

    How dangerous is stacking for 6v? prove it.

    You drive like that? :) Actually a better analogy would be setting your engine for torque or horsepower as compared to RPM. But we typically rely on the speedometer when driving and adjust with the gas pedal (even the cruise control does that). Just funnin guys :)

    Boge 2.0 or 3.0 for eGo C-Twist?

    The higher ohm draws less current but if you run it higher than native cell voltage then the cell has to work harder. If you vape at about the same watts with 2.0 or 3.0 ohms then the watt hours consumed from the cell will be about the same. The 650 mah eGo has a 2.4 watt hour cell in it...

    How dangerous is stacking for 6v? prove it.

    Generally, PWM refers to a lower frequency variable duty cycle DC voltage. Like the eGo at less than 100hz. When the frequency of the pulse train goes higher, like 200000 Hz and is filtered into a smooth DC voltage you can't tell it from a straight DC voltage. MOST DC to DC converters, Buck...

    How dangerous is stacking for 6v? prove it.

    So, separating the 3 ohm coils reduces the vapor temperature (tepid) over say, a bifilar wound 1.5 ohm coil made with a pair of 3 ohm wires into a single coil (about the same as a single wire wound into a 1.5 ohm coil)? The additional exposed surface of the dual coil at 3.7 volts doesn't heat...

    How dangerous is stacking for 6v? prove it.

    Back to my blown dual coil :) If we took three cartos, a 3.0 ohm single coil, a 1.5 ohm dual coil with the top coil blown, and a 1.5 ohm dual coil with the bottom coil blown, and vaped them at something reasonable like 5.0 volts/8.3 watts, which one would produce more vapor? Which one would...

    Boge 2.0 or 3.0 for eGo C-Twist?

    both cartos should work fine with the twist. Start off with the carto/tank you have at about 3.7 3.8 volts and adjust up or down a little to your liking. Even though the Twist will drive a 2.0 ohm up to about 4.6 volts without risking damage keep it to around 4.0 or less. With a 3.0 ohm you...

    Why eliquid should be kept under lock and key.

    Not really news to most of us here but good for you. Toddlers and pets are the obvious potential victims but don't forget the older ones, especially those with Underdeveloped Frontal Lobe Syndrome, you know, the indestructible, invincible, saw it on youtube young adult. Maybe not even yours...

    How dangerous is stacking for 6v? prove it.

    I guess there are pros and cons to both methods (BTW, I only do single cell, non boost, and it works for me). Variable anything gives a more consistent vape than a straight thru mod. Given the ability of adjustment a vaper can fine tune. After a period of trying it maxed out of course :)...

    How dangerous is stacking for 6v? prove it.

    Look up watt monitor. I don't want it to be a matter of semantics either. Most of the chips in the telecommunication market use an external shunt to measure current, measure voltage with a built in AtoD converter, calculate watts and vary an output frequency based on Ohm's Law and a power...

    How dangerous is stacking for 6v? prove it.

    There are complete wattage regulator circuits, single chip. Doesn't care about load resistance, will regulate watts by measuring voltage and current. Regulates output power, period. DC to DC converter controlled by the magic watt chip :) Give your cell phone to your friend and ask him to take...

    How dangerous is stacking for 6v? prove it.

    You can vary volts or watts if you want. Most mods are voltage REGULATED, whereas the Kick or Darwin is wattage REGULATED. Set a voltage up towards the high end of a voltage regulated mod and see what happens (to most) with a low resistance 1.5 ohm carto. (6 volts into 1.5 ohms is 24 watts)...

    I used AW IMR batteries in a boombox and killed them.

    OP: you don't stack those 14500s in a PV do you :)

    I have been stop by a Policemen while vaping..

    I'm not real sure I would want to end up a 'habitual offender' in some countries. Might result in a be-heading.

    How long Should 30ML Nic Last?

    Hooray Spaz. The first one to use the mg/ml unit. If you can't get the units straight how can you ever get a handle on strength and volume.

    Wizard Labs Nic Base Reviews

    I agree. DIY has really made the difference for me. Flavored juices don't keep well and you have to keep restocking. Pre-filled cartos don't seem to age well either. John is very meticulous and his product shows it. He is very polite and helpful (even to a know it all like me :))...

    Wizard Labs Nic Base Reviews

    In a way it's more than just having fun. For example: I've got VG from a few different places. The density of these range from 1.250 to 1.259g/ml @ 22C. One of them probably already has about 3% water in it. Usable, but would take less thinning. I buy nic in 100% PG only now. Why? So I...

    DIY is more than saving money. It's for fun :) I guess DIY accuracy matters most if you have really sensitive taste buds (I don't) or are doing scientific Youtube flavor reviews (I don't) :) As far as the dual mix exercise, I was surprised to come out that close, doing one by volume, and the...
