Dream PV's

[Scottbee]

OK, I think this will be my last installment for a little while.. although I have other "projects" underway.

As I "teased" in a previous post... you can't have a "Super TorneGo I" unless you have a "Super TorneGo II".. right? So here it is.

One of my longstanding gripes about the standard PV design is that we have to unscrew the batteries and "replace" them every time they run out of charge. I think that is kinda silly. I don't have to do that with my electric toothbrush (inductively charged), I don't have to do that with my cell phone (plug-in), and I don't have to do that with my home cordless phones (charging base).

The Bartleby somewhat addresses that.. you can plug it into the USB cable and use it as a pass-thru while it is charging the battery. Kinda cool, but I find the cable to be a minor hassle. What I really want is a charging base. Sooooo....

The first step is to make a battery that can work with a charging base. I had the basics done for an inductive charging system, but I decided to "dumb it down" a bit and go with open contacts. So this is what a TorneGo II battery looks like with open contacts on the blunt end:

You can see that I poked through the end cap, installed an insulator, and then made a center contact that is wired (with a protection diode) to the positive side of the battery. While I was in there.. I modified the stock Joye circuit that limits the effective voltage to the atty. This eGo/Tornado battery is a TRUE 3.7V BATTERY! And yes, that makes a difference!

Now I needed a charging base. I hogged this quick version out of Delrin, installed the pogo-contacts from a universal USB (Kanger) charger and then wired it to some external electronics for charging. Ultimately I will integrate the electronics into the base and put a LED indicator in/on it.

And this is what it looks like when you slide the Super TorneGo II into the base:

Ideally I will have one of these bases at my desk at work, at my desk here at the house, and probably on the console of my car. In-between vapes, instead of just laying the PV on my desk, it drop it into the charger where the battery gets "topped off". Based on my experience with the Bart and this unit, I know that if I vape for 15-20 seconds and then put it in the charging base, it will be fully "recovered" to full charge in about a minute. That works out perfectly.. even if you are a heavy chain-vaporer.

Yes, I can make a clip-on sleeve that connects the battery to a cable like a pass-thru... but why bother?

When I want to get up and move around, I take it out of the base and drop it in my pocket. I know I'm good for a couple of hours (at least) with the existing charge.

During a "hard night out" of heavy vaporizing, I can still swap out the battery with a charged one. But under normal circumstances..... I never have to unscrew the battery. Only when it ultimately dies and fails to take a charge.

The next obvious step is a PCC-style pocket sleeve. But unlike a traditional PCC, this one will be a simple "pack" with a hole in the top. I'll keep it in my shirt pocket (like I used to carry my analog pack).... and when I slide/drop the Super TorneGo II into the hole in the top, it will make contact inside (like the charging base) and refresh the battery on-the-fly. Grab the TorneGo by the mouthpiece, pull/slide it out of the PCC, and vape. Once I have this done, I will unscrew the battery from my PV about as often as I remove the battery from my cell phone. Which is just about never.

Enjoy!

In between those two is what car engines ran off of for 50+ years. A carburetor.

Nuff said.

Genius as always!!!

Do you find that it works for the thick juices? Does it require a very consistent juice viscosity?

I've tried my prototypes with a few different juices.. and quite a few different atties. So far, the "adjustability" built into the unit has allowed me to compensate for variations in atty "draw" and e-liquid viscosity. But that's not an acid test.

I'm going to build one for one of our more veteran and experienced members... and see if he has similar results. If not, I just need to open up the "adjustability" window.

That charging base is a wonderful idea Scottbee.
The eGo is the first device that I actually set down often because of the simple fact that it can be stood on end(yes I know many mods do this but I have none of those) without having to worry about where you're setting the mouthpiece. So a charging base like that would be perfect.

Yeah... it was really the introduction of the eGo/Tornado that made a lot of these ideas more "realistic". I had thought about making a charging base for standard 510 or 510 Mega batteries...but I figured I'd still be changing out a lot of batteries when I was away from my desk or car. Not really what I wanted.

And the liquid feeding system will work with almost any battery... but frankly it looks kinda stupid on anything smaller than a Bart or eGo.

And although I'm all about great "personalities".... looks matter. So does size!

Gotta say, some very nice, clean work there. Love the charging base idea, long overdue.

Yeah while it is certainly more needed on something smaller with less battery life, since they have to be charged more, it would seem,to me, like a bit of a waste of sorts on such a device.

I would definitely say that an eGo-esque device with the charging stand and a reliable 2ml feeding system would definitely be about as close to the perfect device as possible. Although building it so the flip of a button would switch it from 3.7v to 5v and vice versa would definitely put it there

Taking that a step further, being able to use PWM to dial in any "effective" voltage between say 3 and 6 volts using two 3.7 batts (maybe 18350's)... Now that would be something... probably doable also... Then you could adjust for different attys and juice's on the fly.

Darnit. Wish I hadn't sold my o-scope so many years ago. What was I thinking?

Edit: PWM (Pulse Width Modulation): a way to switch a voltage on and off at a high speed such that the effective voltage is something less, (that's in my own words). So, if you had a 10V source woltage and turned it on and off rapidly such that it was ON 60% of the time, it would be about the same as 6 volts... at least as far as our atomizers (strictly resistive load) are concerned.

 

[Scottbee]

After having worked with the Joye batteries for a while, I personally think that PWM is s simple and somewhat elegant methodology for controlling the delivered power to the atty. If I was scratch-designing a circuit, I think I'd go this route.

 

[Thyestean]

Agreed that would be a nice thing to have in another device Ralph. But my remark was made with the idea of a single proprietary battery around the size of the Ego, as it is with the mods Scottbee has already made to it above, without having to get too much bigger than he already has.

Point taken. I wasn't suggesting the next direction anyone should go. However, to get the 5 volts you were talking about here...

flip of a button would switch it from 3.7v to 5v

would require a different battery and/or some significant additional on-board circuitry also.

Perhaps "probably doable on a larger model" would have been a better choice of words on my part.

Kudos yet again for a fine fine design integration Scott. Looks nearly ready to package and market!

So PUT ME DOWN on your non-existent waiting list! Am I third or fourth?

And I'm totally with you guys on PWM - mostly for temp control of the atty but also batt life. I've been researching PWM over the last couple weeks, and have some schematics of a pretty compact circuit used to drop 12v to 1.2. No MOSFETs.

Scott - should I post that in a new thread - under atty mods or ?

aloha

I am definitely interested in the PWM also. I would think it would go under battery mods (since it is supply related), or maybe up one level under just mods.

I wonder if some manufacturer has put PWM in a regulator already, in a single part. Seems like it could be done on a 3 or 4 pin component with a built-in heat sink. You would need a capacitor across the output to smooth it out to a clean DC for powering other circuits, but in our case the "load" is all resistance (ok, and a little bit of inductance), so that wouldn't matter for our application.

I think I need to go stare at a digiKey catalog for a couple of hours...

Sorry... Drifted off-topic again. I really like your work here Scott.

 

[redrhino]

Very Very interesting reading Scottbee....Never even knew that something like that can be made...Just let me know when and where....And yes if you have a list Please put me on it.....WOW.....Great inventions.......

I really hate the lack of inflection in text lol

I completely understood what you meant and was just pointing out what I was thinking when I replied. My thoughts were more along the lines of "hey this would be great if....." while yours are more along the lines of actual possibility

excellent work scottbee.a charging station how in the H33I could i have gone past that. that is probably the most important upgrade.working mind =great mods,well not always.kauai kai,that bomb is scarey but i would use it.it actually made me laugh out loud,so it is great!
ive read about 12v to 1.3v without mosfetts?bms?that really has me thinking maybe a regulator the size of a cigarette pack?i cant wait for that.
the secret is safe still,im really turning in the cranium but its maytag hit and miss right now...haha

ow ya i like that your keeping the oem look.very impressive.

yeah -i LMAO when I saw the HP cart printing text lines - found a smaller version too -

gotta run -will try to post PWM circuit stuff tonite -(over my head skills-wise)

btw-anyone notice we have the beginnings of a "guild" - like structure here? very rapid/efficient means of development, it seems -cooperation beats isolation any day
