Well that makes sense why it is called Blu-Ray... lol
So that means my diode is actually broken, more specifically, the Blu-Ray part.
I'm left with a DVD diode and a CD diode I guess, but still I have a diode, I would like to put it in use.
Now I have "scattered" light, how can I make it a beam?
I read that I need a laser housing module that does that, something like this:
Aixiz Laser Module Housing - Blank [Aixiz] - $3.39 : High Tech DealZ, Simplifying the LASER Hobby!
And I need a laser driver that would "save" the diode, something like this(I think): **broken link removed**
So the missing part of my "pointing stick" is the lense, right?
[EDIT] Oh, sorry, my bad, the Blu-Ray works!
I just used not enough power, I used 2xAAA that is 3V, but blu-ray needs 4.5, so I added 12V (lol, but just for one time) and a blue light shine.
