My first post - lets hope this works correctly! 
This is a pic of my bluray pointer built from a PS3 diode. The two momentary buttons control the violet and red lasers within the diode package, although due to the different focal lengths required the violet laser is well collimated, but the red produces a large ugly spot.
It is interesting pointing it at everything to see how much they fluoresce - for anyone else who has built one, try pointing at a Visa debt card
