Hallo everyone. I am planning to build a lightsaber with these features:
- Crystal Focus v5
- 4 AA rechargeble batteries
- momentary on/off switch (silver guarded)
- aux. momentary switch (the little tactile one)
- rebel green LED
- recharge port = general power switch
- speaker = the one that comes with CF
The question is: I read how calculate the resistor, but I saw that CF uses 3.3V while the Rebel LED has 3.4V and 700mA, so how can this be true?
(3.3 - 3.4)/0.7 ?!
Have I to calculate the resistor with the batteries voltage (4 AA are 6V, right?)?
(6 - 3.4)/0.7

Thank you!
