hello everyone! i need some help with my mini dorcy laser. the last 2 laser diodes i bought , wen i hooked them up to 2 AA batteries(just to test it) they were very dim. am i supposed to put a resistor or capacitor or something on them to make it be brighter???? if so can someone draw a simple picture for me (in paint) to show me how to attach it to the laser diode pins so that it can fit in the mini dorcy flashlight. i have little experience with electronics so im sry if im asking stupid questions.
