Using the Nano Biscotte and need help figuring some things out.

I am currently in the process of building my first saber. I originally was following Lord Dottore Matto's instructions on building a standard saber without sound but now I want to add sound.

I currently have these as my electronics:

Rebel Star LED & MHS Heatsink Module (Deep Red)
BuckPuck 700mA 4-wire
Push on/push off switch with black button (Latching)
4AAA Battery Holder with JST connector

I want to add the Nano Biscotte to this setup but I have read on the forums that I would run into some problems.

1. I would need a resistor instead of a buckpuck.
2. I would need a single cell 18650 Lithium battery instead of the 4 AAA batteries.
3. I would need a momentary switch instead of the latching one I have.

This is my updated parts list for the changes I would need to make to my current electronics as well as the new parts geared for a saber with sound:

Nano Biscotte Sound Module V2
MHS speaker mount V6 - For 28mm Speakers
18650 Single Cell Holder
TrustFire Protected 3.7V 2400mAh 18650 Lithium Battery (2-pack) (I'm opting for non rechargeable because I don't have a hole for a recharge port.)
Premium 28mm Speaker
SPST Momentary switch with black button

My questions are:

1. What resistor would I need and how many of them?
2. Is there a way I can make the momentary switch act like a latching switch? (I don't want to keep holding the button down while I'm swinging away.)
3. Are these all of the components I will need for an led saber with sound setup? (Not talking about wire/jst connectors/heatshrink I can take care of that as needed.)

Thank you.

First off, Welcome to the Forums.

Li-ion batteries are rechargeable (whether or not you have a recharge port hooked up). So, you would need a charger (and maybe the appropriate JST adapter) if you choose to forego the recharge port.

To answer your questions: The NB is designed to work with a momentary switch. However, you won't need to hold it down ll the time like you are thinking you will. Ideally, you can use a 2 Ohm 1W resistor for a Red LED. You appear to have everything you really need to do this.

Thank you.

So would this charger (http://www.thecustomsabershop.com/Tr...rger-P346.aspx) work with these batteries (http://www.thecustomsabershop.com/Tr...pack-P517.aspx) and those batteries have the correct amount of V and mAh for the NB and LED and everything?

And did you mean a 1 Ohm 2W resistor like this? (http://www.thecustomsabershop.com/1o...istor-P21.aspx) that is the only one I found in the TCSS store. Unless the 2 Ohm 1W resistor is something I will have to buy elsewhere?

Thanks for the help!

Those would work fine. I meant 2 Ohm 1W, you could probably get those at your local Radio Shack.

Sweet! Thank you very much! :)

Yes, that would be fine.

Awesome that takes care of all my questions!

Thank you!
