2nd Saber - Electronics list

[sparkyinbozo]

I'm making a dark side-ish saber for a friend and could use a double-check on the electronics list (switch, resistance, etc.). Thanks!

NB Board & harness
Li-Ion 18650 3.7V 3400mAh PCB Protected Rechargeable Battery
2.1 mm power jack
Luxeon Rebel Star (Deep Red)
1ohm 2w resistor
MWS Standard Style Momentary Switch
28 mm speaker & speaker mount
Heat sink, lens, all that jazz :)

10448 This is what it'll look like, but with gold bands instead of silver.

Sounds good to me.

That resistor doesn't look right to me. Rebel DR is 2.4v @ 700mA. With a 3.7v li-ion pack, you're looking at closer to a 2.2 ohm resistor.

SS is right, I misread the resistor, you need the 2 ohm, 1W resistor for that.

Whoops! Thanks for catching that - I guess I swapped the numbers around somewhere in my head.
