Hey,
So I'm working on my first build and i'm building the driver circuit (rather than - buying one). I'm going off of this circuit diagram that I found in another thread - http://laserpointerforums.com/attac...de-laser-diode-driver-ld_driver_schematic.jpg
The laser diode that I'm using however, has a threshold current of about 40mA and an operating current of 100mA.
Right now, however, I'm not entirely sure what battery we should be using. I'd like to use a AA battery, but I don't know if that will give me enough voltage. For button cells, will that give me enough amp?
Help would be much appreciated! My friend and I are quite new to this.
