Hello, I am Spanish, and wanted to know the name of a good resistance to put a diode with 2 AAA batteries, and a module that is not even that power cogere.

I would like to know of a name for the resistance and buy a good module in spain that they can sell to pay less shipping.

Sorry for my English.
 





If you want to use it straight of 2xAAA batteries you shouldnt need a driver. Buy a Capacitor. Ask for a 47uF 16v Capacitor. They cost about 30 cents in Australia. For the resistor you will not need much resistance if you are using a 16x burner laser. Put a 5ohm or maybe a 3ohm resistor on it. When i tested my laser running straight off 2xAAA i was reading around 90 - 120mA so i think you should be fine.
 
Hello, and seen videos in which only use a Maglite flashlight, change the bulb from the torch and put the diode with the top of the module. I would like to know how long it can last if the diode Aug. thus operates with 2 AA batteries
