Intro To The "3DFS ALPHA" By: Digitalciggz.com

[Friend of Atlas]

It was orgininally going to compensate for changes in load to maintain the voltage setting where you set it. I had a whole discussion with Mario about PWM and it was one of the features that was apparently dropped.

Jim how much does the load really vary as you vape? I know you're saying this is a 'differentiator' feature, but if the load varies by .1ohm as you vape, are you, the end user, really noticing the change? I'm just contemplating how much of an impact this will have on my vape?

In all things I am NEVER an 'early adopter' purchaser. I hate spending money, I'm a saver. The EQ is the one exception to this rule and I have no plans to change that decision. (I've always been happy to be an 'early adopter' user - just not purchaser).

I only buy something after extensive research of the product and only if I think it adds value to my life in some way. I still thinks the EQ fits this qualification.

1. It may not have a program for fire-feeding, but it does fire feed without much effort.
2. It hits as well as or better than the ProVari (from what I've been reading), the provari has been an exceptional device for me (mine does not trip out @ 2.0ohm & 5V or 1.6ohm & 4.2V).
3. It is a top-feeding, programmable pump device - this is enough of a differentiator for me at this point in time. Quite honestly I never really thought that constant sampling of resistance with voltage compensation would change my vaping experience enough to be a major consideration. Sure, technically, it's an interesting feature, but... Hey I could be wrong here! The EQ does constantly sample resistance does it not - how else would it cut out if resistance is too low for the voltage (could be wrong here too )?

Granted, I don't have my EQ in hand yet to proclaim that all these things are oh so great, but the point is after reading everyone's first impression I still have confidence enough to PLAN to have an EQ in hand next week (hopefully) to make these judgments for myself.

Guys, honestly I'm having no issues so far. I don't have any atties higher than 2.2 ohm, so I'm sticking to lower voltages, but so far so good. I put my HH .357 back on it and have been vaping it for a few hours at 4 to 4.1v. To be fair, I haven't tried to run the battery down though so I don't know if battery life is an issue or not. I've used it mostly at my computer, so I'm using it as a passthrough much of the time.

 

[NCC]

Really hard to watch with the frequent buffering lags. Arggg.

 

[Drumonron]

Okay guys...I put the completely dead battery that came with the EQ in and charged via usb with only 2 vapes during the charge cycle and it was fully charged, per the EQ's indicators(they stopped cycling), at about 4 hours...not bad really....it makes a very very good passthrough and that's putting it mildly. I'm on my second bottle of juice and this device is really finding a place in my heart.

It sounds like you're going to love the EQ. Can't wait to hear what you think when you get yours...you won't be disappointed, it's a solid unit.

back to you. Please check your email for USPS tracking. The problem was a
loose connection to the control wheel. it has been fixed. Regards Michael

Your order has been updated to the following status:
New status: Update

I received the Email at 5:07 PM PST

I have received tracking for the EQ, It should be back on my desk Monday

 

[Drumonron]

All Right, MX...that's some priority service!!

Will we have an unboxing - The Sequel? -- Just kidding.

LOL I dont think so buddy

I shipped it over night Michel agreed to ship it back the same way. It got there around 3pm and I got tracking and the email about 5pm PST. I would agree that was a fast turn around. I did ask him to look at the juice door but have not heard it that was done. I will update every one when it arrives.

you can't adjust the voltage setting while you vape. you can adjust up or down after you vape - we're talking about the device automatically compensating for changes that happen in the circuit while you vape. The EQ was supposed to do that by keeping the voltage locked where you set it. For all I know the circuit does a good enough job as is so before we blow this out of proportion, lets see what it does in real world with different loads. Hopefully I can rig an old atty up tomorrow with a connector to test it out on the device - my old one broke and I haven't had the need to do any testing in months.... will let you know.

Hey Jimho, I have been looking into your question further about this matter, please excuse my lack of super technical electronic knowledge.. sometime when hit with some hard question I need to ask the team for the proper response. This is the response I received last night from our tech department regarding your question about voltage drops.. and compensation.

"The unit will always attempt to regulate the power delivery under load and regulate to the desired voltage.
3 factors have an impact on how well the unit can get to the desired voltage.

- Type of battery: 2C batteries can not deliver enough power to use a high load. ( that is why we restrict levels with 2c)
- The charge level of the battery. A fully charged battery will be better able to give full power than a battery that's almost empty.
- The load. With a really high load (1.5-1.9 ohm) in combination with a low battery you can see some drop in the output.

It usually a combination of 2 or more factors that happens in a real life situation.

The current is directly related to the voltage ( ohm's law), if the voltage on the output is lower, the current will be lower."

Sorry I could not explain this correctly earlier for you guys.. but yes the unit does attempt to regulate the out put to compensate for drops.

 

[Drumonron]

Michael/Magnetron,

Thanks so much for your time and hard work but regarding your post above, is it fair to make the following statement?

Therefore, in essence, if the EQ is constantly compensating to achieve say 4.2v and, as we all know ohm:

E = I * R

therefore we can agree that it must compensate for the Resistance/Load or the Atty, correct it
must abide by the law to achieve this, minus a tolerance of course.


IE:
4.2 = (I) * 2.0(atty) then I = 4.2/2.0 thus the EQ IS monitoring the Resistance of the atty, correct?

To provide the 4.2v constant it must maintain the relationship between the increasing Resistance due
to usage, waste, age, etc by boosting the Current, yes?

So, it essentially is in fact monitoring the Battery and the atty and compensating, agreed?

Regards

how much does the load really vary as you vape?

More than you think it would. One of the reasons the Darwin is so popular is the wattage setting and if you set the screen to monitor as you draw you would be surprised how it has to chase voltage around to deal with how hard you draw and deal with the changing load as it heats and the amount of juice gets converted to vapor.

I am assuming the EQ is doing similar without the pretty display of it. Mode 9 option of the future?

 

[retird]

From what I read, the Darwin maintains the wattage you select where the EQ maintains the voltage you select.....

This is also my understanding.

Thanks Michael-

That was a pretty good explaination so don't sell yourself short. Your earlier comment yesterday where you said it didn't compensate threw us for a loop, so I'm glad you explained- I never expected constant power regulation but always expected that the regulator would clamp the voltage where it was set as the resistance changes in the atty- glad to hear that was not left out.

In all of these exception conditions that you outlined I think its quite acceptable ....
- the battery being incapable of delivering the necessary current (either because it's depleted or the demand exceedes the battery's capbability)
- The maximum curent output of the regulator is being exceeded and the output is either clipped or throtled down.

To put things in perspective,
In real world situations, the atomizer's resistance increases as the temperature increases- the load actually drops as this happens- there are exceptions such as Kanthal Super which seems to be more stable, but most of the nichrome wire I've found varies by about 10-15% max. I think there are other things going on between the wick, coil and juice that cause things to fluctuate more .... point being that in general, as the atty heats up, the resistance increases and if the voltage remains constant, the current will drop -
All good.

 

[jimho]

From what I read, the Darwin maintains the wattage you select where the EQ maintains the voltage you select.....

That's pretty much correct.

Properly designed VV devices - lets include the eq- regulate voltage to a constant- not as simple as it sounds when you have a dynamic load. On paper you would see small fluctuations because I=V/R and because as the resistance changes, the current would change and since P=E²/R=IE the power would vary as well...

Variable Power - your darwin is the only known example- regulates power to a constant according to the equationion P=E²/R=IE

We can debate which is better till your blue in the face so lets not. Both seem to be effective. Neither is perfect and neither accounts for thermodynamics of an atomizer or varables introduced by juice, wick and other contaminants that change the heating characteristics of your atty/carto....

 

[mwa102464]

Here's what I want to know as far as the booster circuit goes = say you set the unit to vape @ 5V and your using a 10C Batt which is fully charged to 4.19-4.2 how long will the unit last at this 5V setting, until the power cell drops to what voltage will the then 5V Setting drop ?

Without knowing this arent we over stressing our power cell if we set the unit @ 5V and say the batt drops in voltage to 3.6 and where trying to get 5V out of the EQ but it wont give me the 5v I have it set at ? also possibly doing the unit damage too.

And can this effect other things in the unit as well, like the reset problem Jimho is having ?

No debate here, just stating the difference.......

So what really is the difference? One regulates power by adjusting the voltage and/or current while the other regulates voltage by adjusting the power and/or current, but the net effect is the same. Is this a valid assumption? If so, then why all the hoopla over power regulation?
