We all know the Sony Blu-Ray replacement drive assembly for the PS3 and the Blu-Ray Laser phaser project i mentioned in a past article. So we know its possible to build a Blu-Ray Laser with one of these modules, but what makes this project better than others ? It seems the author payed a little more attention to details and added a current-limited power supply opposed to the simple resistor based design. The project also features rechargeable Li-Ion batteries with charging jack on the back and a protection circuit module for Li-Ion batteries. So you can see now that this project brought many improvements to the original one.
