Oh I'm presently writing up a complete walkthrough for a DIY red laser. starting from harvesting the diode to putting it all together in 3 different flashlight bodies with written instructions as well. I just tore into a Sony DW-D26A and netted myself a good diode.
Well, I am already complete on one. I need to reverse the process to show how it's done. Basic and simple. Thing is nice too. I'm putting the last finishing touch on it. Here is what the one looks like so far. The center clear plastic piece is actually coming out and is just a "template" for a black piece.
