I really need help!

Hi,

I have an 780nm 200mW NIR laser diode. It runs using 130mA and 2.4V. I want to house this in a Dorcy Jr. and i was wondering what resistor and silicone diode i should use to lower 300mA to 130mA and 3V to 2.4V. How should i connect it? in series or parallel? I would really appreciate an answer.

Thanks

BTW, here is the data sheet for the NIR laser diode: www.zet.biz/Laser/Data/gh0780ma2c.pdf

I think this should be posted in the "Tutorials, Help & Repairs" section, not the Buy, Sell, Trade.
