Hi Ioannis,

Thanks for the reply. I understand the mechatronics part and not really bothered about it. As I am confident to handle it. (With this forum standing beside). Red Laser LEDs are available but couldn't make a choice for the Green or Blue. Actually no idea if cheap Green or Blue sources are at all available. I want to push the design into the full spectrum. I have seen the projector project using led pointers and mirrors. Really cool. But my application would be different. This is going to be a personal interest development so no time limits and restrictions other than budget . So I would like pointers if it is at all possible to source Green/Blue laser led sources like the red ones.
