All day 5 volt box (and it's little brother)

[Ez Duzit]

Nothing fancy, just functional.
The all day box will go 12+ hours at 5 volts. Uses a 3x AA battery box with two 14500's in parallel. To boost voltage, I use a texas instruments 4050 boost converter. Output under load is 5.01 volts.
The smaller box uses a TI UCC383-5 voltage regulator with two 10440's in series, and will vape 5-6 hours with fresh batteries. I don't baby either one. I sometimes take 2 or 3 hits one after the other and neither one even blinks.
Although, with the smaller box, the voltage regulator can get a wee bit hot, but it cools down very quickly.

Nicely done! What caps are you using on the 4050c box? They look rather large to me.

Looks good Ez! I absolutely love 5V, it's my choice voltage. Have you made a USB passthrough to use while you're at home?

100micro-farad electrolytic caps. That's what the spec sheet calls for. All the ones I looked at were about that size.

Yeah 5v is pretty nice. It's all I use anymore.
And since I get about 12 hours from one of the boxes, no real reason to use a pass thru. Certainly no need to fuss with the wires.

True enough! Gotta love those beefy battery mods I would love to see a Twin 18650 mod running at 5V, that would be awesome!

The USB passthrough was rather simple, just a positive lead from the USB cable running through the momentary switch, then to the center post. The negative lead running straight to the atomizer connector.

That's what I use mostly when I'm at home.

Which box is that?

 

[Vapaholic]

sweet. very cool. well done!

So you get what, about a week from those batteries?

Getting a true 5V (under load) passthrough with a 510 atty is not that simple. It takes a bit more than just connecting wires from a USB cable. What is your source of power? Have you actually measured the voltage while powering the atty?

Getting a true 5V (under load) passthrough with a 510 atty is not that simple.

I agree. USB 2.0 and most motherboards aren't too happy about giving you all that current. And even if you get a powered USB hub, you still have to deal with the high resistance of the wires. That's why you just get a 5V wallwart rated at over 2A and run the wires to you're PT box.

No reason to restrict yourself to USB when you're gonna be tethered to something anyway.

i was wondering how that step up thingy worked i got 3 coming along with 5 5volt regulator free samples could you please post a wiring diagram for the step up with the parallel 14500's

 

[UberDuper]

Nice.. The booster does fit in a AA slot! It's too bad the booster costs so much. I could only find them for $20 online. Have you tried driving the booster with a single 14500?

UD.

I can't tell from the pics how that boosted one is wired. Would you mind posting a diagram?

Thanks,
UD.

Get free samples from TI and save urself the $!

The wiring diagram is on the first page of the 4050c data sheet. http://www.ti.com/lit/gpn/ptn04050c To get a 5v output, no Rset resistor is used. Just leave it open.

It works with mine, but I've only used it like that for a little while, because it really over stresses the battery. Most others that have tried it, said it doesn't work too well with only one 14500. (Cuts out, or doesn't work at all). If you want to try, (using only one 14500), a high quality AW brand battery seems to make a difference. But if you really want only one battery powering the booster, you'd be much better off using an 18500, or an 18650. The bigger batteries have a higher C rating so they'll work much better.

where did you get the booster what site?
a link please sorry if I missed it

How do those 10440s put out the amps required to run at 5v, with a 510 for example it would need 2.25A at 5v, but they are max rated for something like .7A discharge. Scary and confusing!

Two and half days ... heavy, real heavy vaping

Booster comes from texas instruments. PTN04050C - TI.com
Register with the site, and you can get 4 free samples, (one of each package type). But when you register, TYPE the TI address into your browser, starting from your home page. DON'T link to it from here. Some people have had problems registering there, after clinking the link from here.
Also, if you order free samples from there, get 3 day shipping. Don't choose Overnight express. They will do it, BUT, that could very well be why some people have had problems registering there, after linking from here. Don't abuse it. I'm just sayin.

I dunno, but they do it. I use ModernVapor 902 atty's which are ~3 ohms, so the current isn't as much as a 510 would draw. But I actually use the 510's as sort of a stress test whenever I build a box. If it can handle those amps while vaping for a bit, I know it's fine.

Nice.
