Well Im attempting my first mod... only thing is I have no idea how to wire the thing....I have tried searching for a diagram to no avail, is there one? any help is appreciated, thanks.
So far I have the positive battery post connected to the switch, the switch to an led with resistor, then the led to the 510 connection, where do i go from there?
You can't put the LED and resistor in series with the circuit, as you'd get little-to-no current to the atomizer. They need to be in parallel with the 510 connection.
Here is a good schematic, on a site with a lot of good info on e-cig mod topics:
Wiring e-Cig Box Mods - The PUCK eCig Mod
That site focuses on The Puck, which uses parts that can be bought at many stores, but still has much good info that can be applied to other mods.
The wiring for a basic mod is pretty simple. An on/off slide switch is often used to help prevent continuous, accidental 'firing' in one's pocket or bag. A normally-open momentary switch is usually used to activate the mod. both of these should be in series after the battery positive.
The pushbutton is then connected to the 510 connection center post. The outer shell of the 510 connection is then connected back to the battery negative terminal. Sometimes, this is already connected through the mod casing, as in metal mods where there is no electrical insulation between the 510 connection and the case, or the case and the negative terminal.
If you want to use an LED, connect the resistor and LED in series with each other, but in parallel to the rest of the circuit. So, you can connect the resistor to the 510 connection side of the pushbutton, then to the LED (observing proper polarity,) and the LED back to the negative battery terminal or the outside of the 510 connector.
