Currently I am working on building a 200mw red laser that will be housed in a flashlight.
But in order to get it you 200mw I have to push it to about 350mA. But if I run it on AA or AAA's I think the battery will die to fast. But I don't thinik I can just put in a different type of battery. So What do I do to change the battery used. I would like to use a 9 volt if possible.
