Would this be correct just an update on my old thread.

It still looks wrong. The recharge port doesn't look right and the switch also looks like it's plugged into the FoC pad. Also, just add on the previous post - makes it easier to keep track of.

How would you set up the switch connecters without the nb header and clip. With a recharge port (sorry I have tried looking around for diagrams)
Also I am running a red led which runs on 700mA

If you subtract the 2 accent LEDs, the diagram in this thread should be what you are looking for.

Thank you I understand fully now

Just another noob question would I need a resistor to make sure the led doesn't burn out.

Yes, I recommend you use a resistor.

Would a 1v resistor be fine since the battery is 3.7 and then takeaway the speaker power. Then take the 1v allows the led to run safely.

What sort of resistor to dim it down to allow a red led to run? Safely

In the manual, Erv' covers Ohm's Law. SS and I have also dished out those lectures many times. Time to do some research. Hint: The Vf value you would need for a Red LED can be found in the store. ;) Good Luck.

Feel free to post your answer and I'll be more than happy to check it for you.

You need to REALLY go over Ohm's Law. The speaker has nothing to do with the resistor calculation. In addition, the wattage is only half of the "equation" anyway.

if you are not that great with math just do a google search for LED resistor calculator. you will need your source voltage (3.7) the voltage drop for your LED (reds are usually 2-2.3V look up what yours is) and your desired amps. 700mA is safe for reds.

From your method it has said a 2w resistor is required.

This is only half of it, you also need to know what "Ohm" rating you need. :roll:

The ohms was 2.2 and the w was 2w

OK, that will work.

I have a similar set up in mind. I did this math for a rebel Tri Deep Red (2.4V , 700mA), a NBv2 and a Li-Ion 18650 3.7V 3400mAh PCB. It looked like this: 3.7v-2.4v/.7= gave me 1.85ohm I was going to use this http://www.thecustomsabershop.com/15ohm-5w-resistor-P13.aspx

Is this the correct math? It is my understanding that resistors are like the price is right, as close as you can get without going over?

Thanks and sorry to jump on your thread.

Generally it is safer to always round up on resistor values, not down. Jump on up to the 2.2ohm resistor. http://www.thecustomsabershop.com/22ohm-5w-resistor-P11.aspx

Thanks!! After 8 years I'm finally building one lol

I'm willing to bet that it won't take 8 years before you start on your second. This hobby is addicting, the only limit is the depth of your wallet.

thank you for the link and thank you to Forgetful Jedi Knight, Silver Serpent,Parsaver and clahey83. Now Im sure thats all I needed to know when I do build my lightsaber in about November I will show the wiring etc.

I found another users diagram which I will use as FJK has said on the users thread that it could work. It looks like it could work as I have looked at others that are very similar. 10202
Its a modified version of Cire Yeldarbs diagram. Also I have fully got what I require for the resistors even the switch as well. Now just to build it most likely November when it is built. I need to save up for it first :D

I thought so as you sad on CirenYeldarbs diagram it could work. It also matches the one you posted for the nano biscotte. Now I just need to build the lightsaber.
