Oh the ego actually operates the carto with voltage bursts,
I don't remember how many volts a burst has, Scottbee measured them

A battery has volts. They're are either present continuously or in "bursts" if the battery is pulsed on and off.

...vaping results so far

808d1 #3 with 90% PB 10% VG mixture and 1 full ml injected @ 3.7v (majorly reduced vapor production, flavor good in the beginning but seems to be tapering off.

808d1 #1 and #2 with 70/30 mixture, vapor still consistent flavor gone. NOTE: #1 with only 0.6 ml injected no flavor but superior vapor production compared to #2 with full 1ml load injected.

510 carto with strawberry mixture (1 full ml injected) still consistent in flavor and vapor production

And both the 510 and 808d1s are the same resistance, right? I don't think they had the 3 ohms until recently.

Tip of the day:

Refreshing your order history page on the e-liquid.cn website repeatedly doesn't appear to speed up processing any.

I wouldn't recommend a co-op until we get some reviews on all the latest revisions and types coming out. I think everything should be hammered out probably by mid to late August. That's just a guess though so don't quote me.

What if many people want many kinds to review them now during review? I mean what if enough people want some of them now?

3.1v eGo/Riva/Tornado, per Scottbee.

 

[v1John]

^good voltage

I noticed some flavor discoloration too, but I have hope in that it wasn't dekang.
Was that a dekang strawberry?

 

[bssage]

Ok thanks for the help. I guess Even though I read all the post it just didnt sink in how much it was. I think I will be alright now. Thanks again.

So who has the record for length of time in use for one of these??

 

[Scottbee]

3.1v eGo/Riva/Tornado, per Scottbee.

This is what the waveform looks like:

The "scale" is 2V per division.. so in this particular case, the pulses are from 0V to abut 4V. As the actual battery loses charge, the peak (upper) voltage will slowly go down. So then it might be going from 0V to 3.6V. When the peak (upper) voltage drops below a specific threshold the controller will shut off the battery system (blinking LED).

When you "average out" the delivered voltage (RMS, or Root Mean Squared in this case) you get the "effective delivered voltage. Which is a little under 3.1V in this specific example.

 

[Quick1]

What's the time scale on the x axis?

(and is it because it's a cheap Chinese controller that it doesn't produce uniform pulses? )

 

[v1John]

yes I was wondering too, the time duration of energy bursts? and duration of their absence?

 

[Scottbee]

Frankly I disremember the sweep. I can look when I get back home to my lab.

I don't think the pulses are non-uniform due to "cheapness". It's not just a simple oscillator running the "PWM", I'm pretty sure that it's part of the sampling algorithm where the controller is trying to determine if the battery is depleted or the output is shorted (a nice idea that doesn't really work in practice), or if the battery is on a charger. So what you are probably seeing is the effect of the execution speed of the "lines of code". On many of these units it actually is a programmable microcontroller doing the dirty work.

Irrelevant, if the wick doesn't produce peak coil supply in uniform pulses

 

[Scottbee]

Irrelevant, if the wick doesn't produce peak coil supply in uniform pulses

It's also kinda irrelevant since the coil is a thermal device with "thermal capacitance" (not electrical.. thermal). It doesn't heat-up and cool-down immediately, there is a time constant. So as far as heat generation is concerned, the pulses are short enough so that the net result looks almost identical to a simply attenuated voltage (thermally the coil "coasts" through them, "smoothing" them out). And since it is "power" that we are interested in when it comes to generating heat, RMS voltage is the proper value to use.

But I digress....

 

[v1John]

On the other hand, how much hotter can you get it if it was continuous? And would there be enough liquid at the coil? And is lack of vapor an issue? I think vapor is plentiful now.

Irrelevant at short intervals, yes.

Now what if you increase the energy delays, would there be time to bring more liquid to the coil area for the next energy burst?

I understand all that. SO, in your opinion, do you think their intent was to attenuate voltage/current or this is just a side effect of their protection/detection circuitry?

 

[v1John]

See, heat had interest and thus power, but once you deplete the wick, it's gone.
Is there enough time for additional liquid to reach the coil area if the wick is allowed to cool just slightly once during a 4 or 5 second draw?

Even though I don't remember the sweep frequency, I can assure you that these pulses are short n duration.. millisecond caliber short. I vaguely remember the pseudo-frequency being in the 200+Hz range (but don't quote me on that).

Obviously, if it was continuous it would be "substantially" hotter since power goes as the square of RMS voltage. So we're talking the difference between a ~3.7V device and a 3.1V device (about 4.5 Watts vs abut 3.2 Watts into a 3Ω load). That's whay a 3.7V "mod" usually outperforms (from a "heat" perspective) a 510-class (including TorneGo/Riva) unit.

 

[v1John]

Right, what I'm saying is that the ego/510 can now deliver awesome vapor, the CE2s are really nice.

Now what I'm asking is if there is enough time to allow the wick to cool just slightly enough and allow more liquid into the coil area? Obviously not with this particular code, but a more controlled and deliberate one?
