Yes and no. "No" when you're using most LED-driving electronics boards (in this case, CF is providing "smoothed" current, and it is also being configured on the SD card)...
"No" if your LED's fwd voltage matches or closely matches the voltage output of your battery pack...
"Yes" if your battery pack's voltage output is significantly greater than the fwd voltage of your LED (such as if the batteries = 6v and your LED's fwd voltage is 3.85v).
@taichix Correct. The Crystal Focus is regulating + "smoothing" the current being fed to the LED, so... as long as the voltage of your battery source exceeds the fwd voltage of the LED you choose... AND the voltage source is not > ~10v... you should be fine.
One side note for people thinking that a "standard" 9v cell would be OK... ~*NO*~. A standard 9v cell is merely 6AAAA (yes, quad "A") cells, and cannot provide even a shadow of the mA (current) needed--so DON'T use 9v cells. :)
What if your making a lightsaber without any sound effects? Do I still need a board to connect everything? Or, do I just connect all the wires to eachother?
@tean93 and jbsimdawg ... the board is created by Plecterlabs. More should be available soon.

isnt there support to be a resister between the power and the LED?

@greytale 6V source voltage -> CF -> NO resistor -> Led should work right? Because the CF acts like a driver right?

So, your wiring everything to the sound board?

You should watch my other videos. What you're looking for is right there on my account.
