Attach 5V power and attach the yellow wire to ground.

Red to 5v.
Black to Gnd.
Yellow to Gnd.

If that doesn't work, you might need to attach the yellow wire to 5V instead of Gnd.

Yellow is probably MOD, +5v as Trevor said.

The HeNe's I have that have that extra wire require it to be shorted to ground. But since "the light is weak" when it's hooked to ground, you're probably right.

My bad.

If you mean you want it to be portable, this laser appears to already have a driver. So since both the 3.2v and 5v are checked, I'd actually just try running it off a single li-ion first and see how that worked. Or else using two and running them through a LM7805 to get your 5v.

Lasers are used for everything star pointing to particle counting. However around here, generally most people use them for burning, display, or just pointing. A 25mW 660nm laser is pretty much only good for pointing or general experimentation or use as a source for a low power projector providing the room it's used in is fogged so you can see the beam.

As far as building projectors.. It all really just depends on what your going for. They can be as simple as mirrors glued to motors, or huge, expensive and complex monsters that suck up your life savings. heh. It really depends on what your goals and budget are.
