Noob of the day requesting help
I've spent the last couple days looking over what I could find and I've decided that this might be the setup I want. First, note that I'm not saying to use both green and red, just listing them as options. I'm trying to focus on getting the lighting electronics figured out before I go any further...
Nano Biscotte v2
12mm Anti Vandal Momentary Green Ring Switch
18 ohm / 1/4 W resistor
Rebel Star LED & MHS Heatsink Module (Green)
1000 mw buck puck
Rebel Star LED & MHS Heatsink Module (Red)
700 mw buck puck
Recharge port tbd
Speaker tbd
Panasonic Li-Ion 18650 3.7V 3400mAh PCB Protected Rechargeable Battery
Here's the wiring diagram/calculations I made:

A few questions I have if anyone would be able to help me with
1) Am I better off going with the buck pucks or finding resistors to suit my calculations?
2) Are my calculations correct? / Will this all go poof as is?
3) Do I have enough voltage for my chosen setup?

1) The Puck Bucks will not work for those LED's, with the Battery you have selected. (minimum forward voltage requirements for the puck buck is > than the battery)
AND
2) You cannot use Puck Bucks with the Nano Biscotte. (The NB has a Voltage max that is less the the Voltage need by the puck buck)
Puck Bucks are used for "Stunt" builds (no sound), as they offer constant current (which means the blade won't dim as the battery drains, as it would with traditional resistors).
The sound board does not current regulate, so you would need to resistor those LEDs so you don't cook them.
You could get away with not resistor-ing the green, by using that battery, and tweaking the NB settings, but a choice is to resistor as a safety measure.
The red will HAVE to have a resistor, period.
Credit to FJK and SS for posting this answer so many time, even I memorized it!
I'll leave the wiring diagram review to the "experts".

Thanks Kevin. I guess I just need my calculations and wiring checked. Having a hard time finding the right resistors based on my calculations, so I wonder if I got the voltages wrong.

Your calculations are correct, more or less. You will likely have to "round up" to get the resistors you need (and are commonly made). .5 Ohm 1/2W, 2 Ohm 1W, 18 Ohm 1/4W. Other than that, the diagram looks ok.

Thanks, FJK. I'll see what I can do to find some. I'm just surprised that my calculations come up with something that isn't stocked here because I would think that most of us would come up with the same numbers for common configurations. So the best thing to do is round the numbers up to be safe? How high is too high a variance?
And the next challenge...get the Lithium battery into Canada...hmmm...

I basically gave you the resistors that you would need. Tim DOES carries 2 of the 3. The calculations themselves are one thing, what is commonly produced by manufacturers is another. While Tim tries to carry the common ones, things change, and it's not always easy or prudent to keep up, so... it is what it is.

Is there a thread on how to get batteries legally into Canada? Ive been looking for quite some time with no results ,
