Hi, I have an 200mW NIR diode, it powers with 130ma and 2.4 volts. I want to do a Dorcy or Minimag hack with it, but there is a problem, the AA batteries will overload it and kill it. So, the question: What kind of resistor (10ohm, 11ohm, 12ohm, etc.) should i use to lower the voltage from 3V to 2.4V and lower the current to 130mA. Remember, this uses standard AA batteries.

Thanks, I would really appreciate an answer.

BTW, here is the datasheet for the diode: http://www.zet.biz/Laser/Data/gh0780ma2c.pdf
