Ah okay! Yeah I just got my batteries in! And I don't have a holder for these big boys lol! Thanks man :) -Brandon

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...

Yeah sorry meant rosin core solder and rosin flux, but I picked up some rosin flux that wasn't acidic from RadioShack so I won't used the acid flux on laser stuff :) Thanks again! -Brandon

Alright I was practicing soldering and used the flux on some simple LEDs and nothing happened but is there some kind of flux that is rosin core but paste as well? Also the solder I am using is 63/33 and it has rosin core 2.2% flux do I need flux if the solder has it, or is it not enough?

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

Ahh I see was just curios about it! :) I just bought a multimeter... Even though the drivers I got from Blord I want to learn how to use a multimeter! It's just one adventure after another on here haha ;) -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...

Yeah just broke my solder back out, it's time to upgrade... It has one temp, not even a high/low setting... So I will upgrade to a soldering iron I'll be able to set the temp to what I need

daawood123 im interested in that too i have an old soldering iron but it works fine, ive been looking towards getting a new up to date iron though because the one i have is about 8 years old and i like to update my stuff :P

Ok! Ill make sure i go and buy 63/37 solder for this! what i will do is practice soldering 2 plain wires very quickly! So i can master <1 second, but I will also try the dropping the solder approach to see if it is as easy as pictured! But also when you do your quick solder im guessing you...

Is it possible to heat the solder and have the word in place then drop the liquid and connect them that way to prevent actually risking the chance of touching and heating the door too long? ( If it's possible thought it might be an interesting risk free way) -Brandon

Thanks y'all! Will do! Appreciate it! -Brandon

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...

Thank you Blord! also how quickly do i have to solder? Its the soldering of the diode that can harm it if i dont do it fast correct?

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...

Okay sounds good thank you! I just really did not want to mess it up!

It is this driver, here's the link: 445-450nm 0.3-1W Laser Diode Drive | eBay That's the driver i have

No I don't want a torch light style host, I was just curious if my concept of connecting it all was accurate , first you have a diode then... You connect the positive and negative wires to the diode, then... You connect the othe end of those wires to the driver, then... You connect another...
