I am not sure if this is the correct place to post this. I apologize if I am wrong. I am following a simple build by youtuber styropyro. Using this, http://www.dx.com/p/200mw-532nm-green-laser-module-3v-11-9mm-26891?r=93098389#.Vp5gTuBOnqA in the build he suggests powering it with 2 AA batteries. I have a 4x AA battery holder already and was wondering if that would be safe to use ? 4 AA's vs 2 AA's ? Or if anyone can suggest a smarter way to power it ? I have never built a laser and this one seemed to be a good FIRST build. Also I will solder and build it with better quality than used in the video lol smh. Here is the link to the video. Thanks. https://youtu.be/Y7JavGjcb0Y
