Greetings fellow saber enthusiasts! I'm looking to dive head first into building my first custom saber. I've poured over these forums, as well as the YouTube channel; watching countless tutorials and drawing up (crude) diagrams to put together the guts of the beautiful Sith Relic I've been designing in my mind.
One hiccup: I know bubkiss about electronics. Now, I can use the different formulas to calculate watts and ohms just fine, and I know there's some wiggle room when selecting your resistors. But just to be safe, I figured I'd run it by you fine people before I spend a whole lot of money to (potentially) create a big puff of smoke.
The components I plan to use:
Nano Biscotte V3
Red/Red/White Cree XP-E2 CopperNova
Panasonic 18650 3.7v Battery w/ recharge port
12mm Red Ring AV switch.
2x Red Accent LEDs (for crystal chamber, 2.0-2.2v, 20mA)
As for the LED in the 12mm switch, as well as the two accent LEDs: I plan on running these in parallel off of the 3.3V Power Indicator pad featured on the NBv3. Am I correct in assuming that the 20mA DynaOhm resistor would be adequate to run these 3 LEDs safely?
Second question: If I've done my math right (and unlike Tony Stark, I may have botched this), I'll need a 0.38W, 3.17ohm resistor for the twin Reds, and a 0.55W, 0.55ohm for the White. Did I do the math right? And if so, which resistors should I use?
I bow to your superior knowledge, and thanks in advance!
