GG custom production line

[caesar]

Resistors are not good to step down the voltage as they will get very hot and eat that battery faster then the atty.
There is a simpler method to regulate that voltage, it takes only a 20mm wide and 4-5mm thick disc to regulate that without loosing any of the battery charge for stepping down the voltage.
You can also program it to start high then after a few millisecs to step down and just keep the atty hot. Or even make it user adjustable, or add a professional pressure sensor so that it is activated by a drag.

I can help if there is interest in small (programmable or even drag activated) voltage regulators. The GG surely deserves this.

caesar, I must thank you a lot for your help, I really appreciate this but I want to keep the GG the strongest ecig but wireless. If the future shows to me that I must put wires (because there is no other option), I will ask you for sure. You look like a knowledge man about this stuff. Are you electronic?

ps..... I think that I have found a wireless solution for this, but I am not totally sure. I am keep trying.

So the GG is purely mechanical? Well done!
You're right, small custom intelligent circuits are my hobby.

I was thinking about the two batt version, 8.4V (2xLi batts fully charged) is a little too much for a poor atty.
And because you can not mix two protected batts, you will also need some discharge protection.

Thanks caesar,
I like your hobby, I like hobbies like this, I am very attractive to those things!
As for the volts, the maximum is 7,2 (3v batteries, 3,6 full charged) but drops quickly to 6v.

If I understand well you said that I cant put 2 protected batteries in series? Why? I dont know that but the cr2 I use are protected

 

[caesar]

Actually a 3.6V Lithium rechargeable has 4.2V when fully charged and should not be used under 3.2V. It will simply get damaged and will loose it's capacity if overdischarged.

Protected batteries have a controller that cuts them off if overcharged or overdischarged. If you mix two protected batteries with different charges, one of them can still get overdischarged or the protection can kick in.

Two batteries will never have the same capacity so they discharge differently.

Mixing two protected batteries can fool their circuit into thinking that the voltage is still good even if it isn't the case, getting one of them overdischarged and rendered useless in time.

This problem is solved by using a little higher cutoff voltage for discharging two unprotected batteries so that the battery pack remains safe and mixing only fully charged batts.

Mixing batteries with different charges will surely damage them quickly (over a few usages).

Maybe your setup works because the protection kicks in and doesn't let you put more than ~1A through your atty. At 8.4V it should draw more than 2Amps and get burnt right away.

From what I've seen (not 100% sure but seems logical) attys are designed for a current draw of around 500-800mA depending on design, some models being able to withstand 1A too.
I think you are lucky with your straight twin protected CR2 setup.

Caesar, thanks for the info, I like learning things
But I know already all these stuff but my purpose is to put batteries on the GG with exactly the same charge. I dont put a used battery and a new one together, this would be a crime, I know, but if you put 2 batteries with the same charge isnt it safe for the batteries? I am sure it is but if you have another opinion please tell me

Ceaser, I think you missed the fact that the GG uses two 3.0 volt batteries, not the 3.7 volt ones. The CR2 is a 3.0 volt battery with a max voltage of 3.6v fully charged.
You are correct about 2 of the 3.7v being too much, It just pops the atomizers pretty quickly.

How are you Sakis? Well I hope.

 

[wegster]

lol (suitcase)

Ok, so now...'only the 5v problem remains'

Is there any combo of batteries/transformer prices/tube lengths/spaces that provides closer to 3.7v and 5v options, vs 6-7.2?

Can you explain this one? I was thinking maybe a disk, which had solder on *it*, but was a mechanical connection inside the GG, with a pair of diodes on it..yours sounds more like a small IC with the adjustability, ramp-down, etc?

 

[imeothanasis]

weg, I really dont know why we are talking all this time about the 5 volts. Its useless because we could talk about 4,9 volts or 4,8 volts, or 4,6 volts until we stop to 3,7 volts . The 6 volts are the border and its the best one because it gives the best performance and results. All the others are solutions between the best and the regular. GG has regular and best together in one device, so the solutions between these 2 options are totally useless. Thats my opinion.

ps...... this post is not for you but to all people that ask about this stuff.

Don't want to get into a flame war but help me understand instead please!
If they are rechargeable then it's 4.2V charged and 3.6V discharged.
There is no rechargeable Lithium battery rated at 3.0 to 3.6V that I personally know of and may be my mistake.
If it's written 3.6V Lithium rechargeable then it's 4.2V fully charged, a multimeter can confirm the exact voltage.

Diodes are the easy way but can still get hot and precious charge is lost.
My idea was of a plug-in disk, more like a sandwich that you can adjust, either for starting voltage then quickly for maintaining voltage with a cutoff at 10 seconds if desired or just a plain adjustable power limiter, driven by a microcontroller (why not do it right?)

[...]the solutions between these 2 options are totally useless. Thats my opinion.

I'm not saying to modify the great GG in any way! It would be just a small gadget to have around and help customize the vaping experience.
It can enhance battery life for the medium vapers and hugely improve it for the single batt vapers if they use 2 batts for casual voltage vaping while only taking up a very small space.
(just as a sidenote, because it's not GG's case, connecting lithium cells in parallel is not a good idea!)

Hi Ceaser, welcome to the forum. Do a search on google for CR2 rechargeable battery and you will find that the 3.0v(max 3.6v) are plentiful. Not as common as the 3.7v(max 4.2v) but that's what the GG uses to get 6v. Mine have a protective circuit that cuts off at 2.0v (metered at 2.1v) to prevent over discharge. These are from http://www.dealextreme.com/

Got it, similar ideas, but yours is 'a step further' and could be entirely adjustable...figured a 'drop in disk' is the easiest'/cleanest that might fit into existing GG. *I* like the idea, dunno about others, but then again, I think I'm already driving Imeo nuts because I'm unsure about vaping at 6+ volts Plus, cost to manufacture versus something simpler? I'd expect the chip(s)/parts would be relatively low-cost (DigiKey or equivalent), but what about assembly in time? I'm guessing the 'disk' could perhaps be a 'sandwich,' with components on the 'inside', and connected to the other disk via a small standoff, so everything is protected on the inside? Or do you have a different idea? (I'm picturing a disk that is set, then dropped into the GG, inline with the batteries, with a contact on each side, and any components on the inside of the sandwich..?)

Caesar, no flame friend, there are no flames in this forum. If someone want to make one he will burn itself. But we have a passion here and sometimes its big enough to look like a flame!!!

I must thank you again for the propositions, I dont reject anything and its possible that soon I will ask for your help

Thanks for lighting me on this one. They seem to be LiFePO4 or worst case LiCoO2 with diodes, worst case cause they never get fully charged, and the diode could be called "protection circuit", pretty evil, I know.

The good part, they never get over 6.2V in a pack and are current limited too due to the diodes.

wegster, we can move this idea in a new topic and keep everyone happy, we don't want to hijack the thread.

the components would be surface mount between two copper plated discs, pretty cheap so the disks would be sealed and insulated, making a sturdy assembly. 1 or two small hole would allow to set up the current or voltage.

You got the picture of the sandwich right.

 

[mmmvaping]

I like the concept of the GG. iTs so simple that it will last a long time even with severe where and tare. Try that with every other ecig on the market and they wont even come close to the strength and simplisity of the GG. Im not blowing smoke up anyones ... I've been doing some serous research on all the mods and ecigs out there and none of them have what it takes to keep up with the GG. There is no solder or easy breakable parts. every single part on the GG except atomizer is custom built to last a life time. Thats why I cant wait to get the GG slim.

 

[mmmvaping]

this maybe a crazy thought but I was thinking that maybe you could create a different GG for each of the greek GODs and Goddess'. Keep the same parts but make the body different. like for opallo make the tip like an arow. or the greek god of war shaped like a sword.

OR DO a set type of engravings like for opollo engrave a stylish airow on each side. for the greek god of war engrave a war horse, chariot and rider. or something like that. i know stupid idea.

 

[imeothanasis]

Your idea is very nice mmm but 2 reasons (cost ant time) preVent this. But I think that GG has everything in it for now. Now that we secure the button (many requests for this) and the engraving we are the best smokers

 

[wegster]

Securing the button as in locked so can't activate? If so, nice.

psst...3.7v/~5v/6+vDC transformer...done yet?
