DIY Laser pointer Answered

Hello everybody, I'm sorry if this is already explained in an instructable, but I can't seem to find one... My question is, is there a way to make a laser pointer from the laser thingy inside an old cd-writer or an old hard drive (that both still work) ? Thanks

Every time I see that "hack" I'm about to lose my mind don't follow that instructable

Though I thought of something excellent using that hack and another hack on 'ibles, I'm thinking big and clever...
