Volts question

[Chuber]

Hi... Im from Argentina, and i am still working on my first saber. I am using a Luxeon Led 3W Red and an Obi´s hasbro sound board. I used 4AA batteries with a 2.2 resistor. But i need more space in my hilt, so i was wondering if i can use a 9v battery (duracell or a rechargeable one) with a bigger resistor. Would it work? Which type of resistor do i need? Can i use instead 2AA bateries with a smaller resistor? I am a little confused. Thanks and sorry about my english... (here in Argentina we speak spanish)... Thanks again!!!

Or maybe 4 AAA will be better?

You can use a 9V... but your runtimes will be awful. The resistor needed can be found on the chart via the front page of TCSS. You mention a hasbro board though... even though 9V's are weak I don't want you hooking one up to a Hasbro unless you already have a setup to avoid the voltage.

Personally a better option would be 2AA. This is not ideal either, but it will work WITHOUT a resistor.

i think xwing has this one covered. i just wanted to compliment you on your english. i didn't notice any typos, let alone any grammatical errors. thanks for having easy to read posts!

Thank you Xwing for your answer... and thank you Cheeker for your comments... One of this days i ´ll be posting some pictures of my finished saber...
