Hey y'all I finished my first laser build the other day with a m140 diode set at 1.25amps! And I mounted it in a home-made Ironman like glove! I decided to do somthing kind of neat for the first one :) For how it works, when I flex my hand (by pushing palm out and stretching all my fingers the...

Hey y'all I am curious if a standard 2 "AA" battery holder would be fine to hold 2 18650 3.7V li-ion 300mAh batteries or would i need a different battery pack?:undecided: Would there be a problem with using a standard pack from like radioshack or should i get somthing different? I saw these 2 on...

I've just bought a flux paste that will be easy to apply because I can just dip the ends of diode pens in it and get a little on them, but before I commit... It is an acid paste flux, with zinc Chloride, is that okay for a flux or can it harm the diode when soldering? Thanks!!! -Brandon

Hey y'all, I was looking to but some Silicone insulated wire from someone, prefereably 26 AWG, although I am fine with anything close to that! Or does anyone know a good place to buy some wire from?? Thanks y'all! -Brandon

I watched the Solder 101 video posted a while back and learned a couple new things about soldering. Now... I am going to use the 63/37 ratio solder for my laser because of lowest melting point it goes the fastest... I still dont understand one thing :confused: 1. What is the difference...

Howdy guys, I have been researching on the forums for a couple of weeks now and decided to finally make my own account! Lots of awesome people on here! Have been really happy and appreciative of the help i have been getting! I am 18 years old and will be attending Texas A&M this fall in...

Im sure this will come off a silly question but im serious about it. I have seen many tutorials and etc on this and never have had it clarified... Does it matter which side of the driver has the +/- connection to the powersource and the +/- connection to the diode? or Can I just pick which...

ok the diode and driver i have say it works best at 1.25A now the batteries i have are 18650 3.7v li-ion batteries, the trustfire brand at a capacity of 3000mAh... so if 3000mAh is 3A its too powerful... buts thats just the capacity right? How many mAh are my 18650 3000mAh batteries actually...
