How to Build yourself a small 5v triple A box with microswitch using pcb

[Connman]

This is a great way to make a 5 Volt Thanks Ez Duzit.
I do have mine working but wanted to find out if possible

Can anyone tell me what the resister placed here is for?

"While the epoxy sets on the battery contacts, you can solder the resistor into place. Pictures 20 & 21 each show different angles, so you can get the best view. I stripped about ½ inch from a small piece of black wire, and then cut that insulation to proper length to fit over the exposed leg of the resistor. The resistor gets one leg soldered to the control pin, which is row 4, and the other leg is soldered to ground, which is row 3 of the pcb. Make sure you are keeping the correct orientation of the pins, (1,2,3,4), and not reversing them. (Each pin corresponds to the same row, ie, pin 1 is row 1, pin 2 is row 2, etc… I numbered the pins in Pic 21 to help prevent mistakes. So be aware of the pin orientation."

This step is located right above Pic 20

I made this diagram here. When I had some trouble only to find out the 2nd pin solder needed redone and it started working.

But raised the question I now seek in this thread.
http://www.e-cigarette-forum.com/forum/madvapes/75979-5-volt-mod.html#post1127407

Could be the resister is for LED? Or is it just required for some other reason I`m not aware of?

Thanks for any feedback to this question.

Hi Conman. The resistor between rows 3-4 is necessary for the control to work properly, so you can use a micro switch.





An led with a resistor would go between row 2 and 3.

Nice to meet you.
mod that was able to adjust power by a different approach was made though it was not a microswitch.
It opens to the public in the blog, and refer, please if it is interested.

Hello Ez Duzit,

Love your instructions, getting ready to build my own 510 - 5V box.
Please excuse what may seem like dumb questions but I know nothing of electricity, currents, resistors...........(trying to learn as I go)
I did build a Nicobox with 2 x 3.7v 10440 batty in in Parallel for doubling the capacity, 1 x momentary switch, 1 x AAA box\master switch. Works well but now I would like to build the 5v or 6v box as I like the vaping on it better.

Need a bit of help:
what is the 470 ohm resistor used for?
to drop voltage from lets say 8v (2 x 4.1 10440 batty) down to 5V?
I was under the impression that the 5v regulator did that job?


For this project I have purchased the following:
1 x AAA box\master switch
2 x 3.7v 10440 battys (4.1v fresh of the charger)
1 x PCB
1 x +5V Fixed-Voltage Regulator 7805 - RadioShack.com (now not sure if this one will work as your instruction say to also use 470 ohm resistor with a different model regulator)

Not sure which switch can handle the power:
1 x Mini SPST 0.5-Amp Momentary Switch (4-Pack) - RadioShack.com
1 x Mini SPST 1.5-Amp Momentary Pushbutton Switch (2-Pack) - RadioShack.com

Please find a minute or two of your time to answer as best as you can my question.
Once again thank you in advance.

Best regards,

Vadim.

Hello EZ Duzit,

OK, I see now that I need 470 ohm resistor so I can use a micro switch

I also see that 470 ohm resistors come in different flavors:
1/8-watt, 470 ohm
1/4-watt, 470 ohm
1K ohm, 1/4-watt, 470 ohm
1/2-watt, 470 ohm

can someone point out which one I would need, want to make sure I buy the right one.

Thanks,

Hi Vadim - Couple of things for ya. The 7805 regulator is a bad choice because it is only rated at 1 amp, and a 510 at 5v will draw MORE then 2 amps. So you need a regulator rated for at least 3 amps. Also there would be no need for a 470ohm resistor because the 7805 does not have a control pin.

Here's the one I used from Madvapes. LDO 5 volt, 3.0 amp regulator with control pin! And a 1/4 watt 470ohm resistor is fine for the control circuit.
You'll also notice the regulator with a control pin has 4 pins instead of 3.
*The extra pin is for the control circuit, which is what allows you to use a tiny micro-switch.


*If you use a regulator without a control pin, the switch must handle the full current the atomizer draws, which is over 2a with a standard 510 atty. Using the regulator I mentioned, the switch only has a tiny bit of current passing thru it. That is what allows you to use one of the really tiny micro-switches, which gives the box a sleek appearance, and is much more comfortable to use.

Hope this helped.

Hi EZ Duzit,
Got it, all good.

For 510 modbox:
Need regulator rated for at least 3 amps weather using a switch or not, got it.

If I want to use a micro switch (or any other switch) then need regulator rated for at least 3 amps with control pin.
LDO 5 volt, 3.0 amp regulator with control pin!

Awesome!!!
Like I said “learning as I build”.
EZ Duzit thank you very, very, very much!

Will place order with Madvapes now.

Vadim- When I was referring to the switch, I was talking about the push-button switch, not the on/off main switch. Just want to clarify that, because I'm pretty sure you'll want some kind of button switch to activate the atty, whether you use a regulator with a control pin, or not. The main on/off switch basically prevents the box from powering up accidentally while in your pocket. So if you do indeed want to use a tiny tactile switch like the one I used (6mm x 6mm Tactile Switch with 4mm actuator), then you will need the regulator with control pin. That limits the current going thru the push-button switch to a very small amount. It also has a much better feel (you gotta love that little click). The tiny tactile switch also sticks out of the box only 2-3mm, compared to a common 2 amp rated switch, which sticks out about 3/8".

With a standard 3 pin 5v regulator, you can still use a push-button switch, but it needs to be a heavier duty, larger switch like this one, ( Push Button Switch -- Red). That's because the full current load is going directly thru the push-button switch every time you press it.
But it is also a little different circuit. Below is a basic schematic for a 3 pin regulator (without a control pin). Pin 1 is input, pin 2 is ground, and pin 3 is the 5v output.
Hope I didn't confuse you, but if you have more questions, ask away.

Edit- Just to avoid confusion, if you plan on using a tiny micro-switch like I used, then use the original schematic (and directions) from the tutorial. It doesn't have to be the same switch I used, any micro switch will do.
But if you use a 3 pin regulator, then the circuit below is the one to use.

Thanks EZ Duzit,
Absolutely no confusion, you have explained all in very easy terminology.
My mistake, when I said “with switch or without” I meant the push button (micro) switch; the Master ON\OFF is there by default.
And yes if I choose to use a 3 pin regulator then I would either choose not to have a push button switch or install one that can handle 3A.
Thanks again for easy to understand instructions, once I build it I will post it.

All done, finished it on Saturday.
Did not think I had it in me but with all the help which I have received at this forum I was able to put it all together for a beautiful and a well made 5v. vaping mod.
Thank you Connman
Thank you Ez Duzit

Thank you e-cigarette-forum

 

[Ez Duzit]

Glad to help Vadim. It's always so much more enjoyable to use something you made yourself. Any pics for us?

 

[Vadim]

I'm at work now and the only camera available is on my blackberry, please forgive the poor quality of this pics.

 

[Vadim]

Here comes the vapor!

 

[Connman]

Got to Love a home made mod that hits so well. I`m so happy with mine and that`s a Giant thanks to Ez_ Duzit.

You set yours up like I have mine with the batteries staying side by side. Very nice Mod job Vadim.

Looks good, and puts out a huge vapor cloud. What more could you ask for.

Always happy if I can help someone out. That makes me

 

[Vadim]

I am very happy with my new e-cig MOD.

Instructional credit goes out to Ez Duzit (also for holding my hand thru out this process)
Also want to thank Connman for giving me some good advice and Welcome to MadVapes LLC for all the parts to build this wonderful device.


PS: next item on the list will be a smaller box but larger batteries 2 x 14500 for 5V.

Congrats on a mod well done! I made a 5V 2x14500 in a 3xAA box using EZ's post as a how-to. I posted some pics and wiring diagrams in this thread if you are interested.

Thanks, EZ, for the great how-to!

Thank you, thank you, thank you, it was my first but not my last.
Yours is very impressive and very clean too.
Question: what is 10 uf 10v Multi layer capacitor? I looked it up and it said "Used to filter out interference and to smooth the output of voltage regulators." What interference? Could this be the reason my MOD shows 4.9v at the 510 batty connection and not 5v or 5.2?

Best Regards,

I'm currently in the middle of this mod and its my first I have some noob questions.... when I soldered the pcb board what should I do if some of a tiny bit of solder gets to row two... Is it possible to use a exacto knife to cut it out and still move on or is this a complete fail...?

 

[Soundwave]

WHOOOOOOHOOOOOO I just built my first mod from this guide and successfully!!!! I can't belive I did it! Never soldered or touched anything like this and I did it!!! I'm vaping at 5v for the first time at 4:38AM Sunday Jund 6 a day before my birthday!!! WHOOOOOOHOOOOOOOOO Thank you for giving me this guide that allowed me to do my FIRST mod!!!! First pic and video will be posted with review of the challenges I had as a first timer.
