Chagrin:
Honest question: why does this circuit work? You have four strings of 16 LEDs in parallel, being fed by a constant current driver, but no single LED goes into a runaway that takes down the string?Nice "hilt" btw. Did you CNC that yourself (employer's machine, I assume)? Assuming that's aluminum you managed to get that a perfect finish on it.
I'm assuming your addressing "onesky" as I never posted a diagram of my circuit. I have 120 LEDs in parallel driven by an LED driver that I linked to in my first post. I did not machine the lightsaber, I actually ordered the parts from the Custom Saber Shop (website).
