5 Volt Mod?

[Connman]

After I reworked this Diagram hopefully for the better I figured it should be updated to a working Diagram rather then when I was having trouble with my soldering job.
Hope it helps those who appreciate these type things.

It should be noted the Regulator is viewed from the top.
And the pcb board is the white side without the copper strips. The copper strips are on the other side where you do the soldering.

To add a LED you can use pin 2 and 3


5 Volt gives vapping a nice boost when needed.

Sorry Hoogie,
Check all my spots over and over and I had noticed pin 2 was not sticking all the way out of the board and had to let the solder settle down into it for deep penetration. Hit the switch and pop we got 5 volt going on now.



Love the piece of board for sure the way to go.



Feel free to delete this if you want.

Please don't delete this! If this is a diagram that works, leave it as another reference!

Is that an LED between pin 3 and 4? Where does the other wire for the main switch go?

Hi KarrMcDebt,

No Led that`s a Resister oops I also seem to have called it a diode.
I`m running the LED today if I get to it.

And the other wire for the main switch would be coming from the ground battery post. The main switch is the one already in these boxes and only needs the black wire connected to pin 3. Hope that helps. Working great by the way.

I also redid the diagram but since this post I`ll stick the new one up here next

Here is the New Diagram for those interested.

To add a LED you can use pin 2 and 3

so to add a LED you solder the 470ohm resistor to pin 2, the led to the resistor and the other leg of the led to pin 3, correct? (keeping in mind the polarity of the LED)

That's right.

Very nice diagram.

One thing folks should be aware of though.

According to member Charged:

That device is a Fairchild KA378R05. You are aware that even with the inhibit pin pulled to ground (device disabled) your are still pulling 10ma of current from your battery. In other words the device never really turns off. I see you have a master switch so that is a good idea.

Thanks WillyB. And glad you pointed the constant power thing being on part. That`s why I installed the green LED on the actual one I made here.

Nice. Seems you are always ahead of the curve.

Don't know about the paint though, I've always preferred 'nude'.

How safe is this. How much drain on the batteries is there.

Other than remembering to use the master switch, are there any other things to remember with this circuit?

I know this works but hopefully someone can tell me why:
1. Switch is connected to voltage in, getting 8.6 volts and the control pin, no ground, is it cause the resistor is connected to ground?
2. What is the voltage coming out of control pin to switch supposed to be?
