Hello.
As the title states, this is a tutorial for building a laser pointer. The thing that makes it special is the fact that I used fiber optics to use the diode's own output to make an "activation indicator" light. Functionally, it doesn't do much but it looks cool!
I made some chrome pens like this a while back but this time I used better fibers and a more powerful laser - an M-140 diode producing about 1200mW with the 3 element lens and about 1500mW with the 405-G-1 lens.
I am using Wolfman29's blitzbuck driver powered by 2 14500 LiIon batteries. The relatively large (for a "pen style") aluminum host provides adequate mass for about 2 minutes continuous operation.
Below are some more images of the completed laser and the video will explain the rest.
Toward the end of the video I have some cool beam-shots so if you want to skip all the instruction, go to about 15:48.
Enjoy!
Watch on youtube in full HD! Especially recommended for the beams!
