@DJNY - Appreciate it. I am working on some nice shots of my 300mw LOC 650nm now. Figured out a bunch of new techniques since these shots. Less distortion and better beam consistency! Be up tonight prob so check them out if you can...

Re: The "Blue Ninja" - 445nm DIY Creation thanks for the help guys I appreciate it! just wanted to make sure I wasn't over killing anything...

Yeah the 3rd and 4th ones where my fav also. The last 3 or so i changed positions and my breathing started to get in the way a bit. Thanks for the nice comments and +rep on post! Appreciate you taking a min to check them out!:thanks:

Re: The "Blue Ninja" - 445nm DIY Creation Oh i am using Duracell 3v lithium batteries not rechargeable li-ions. So thats why i mean like after a few seconds of use at around 1amp they fall bellow 3volts a piece, so would you say 4 of them would be better. I have checked and after only a few...

Re: The "Blue Ninja" - 445nm DIY Creation I have been unsure what minimum volt i need cause i am using a140 445nm diode & lm317 linear driver i only had 1/4 watt resistors so i went with 5 in parallel = 1.5ohms which gives me 930ma max. anyways do the extra resistors use any extra volt or...

These are just my first Beam Shots ever... I never could figure out how to get a good beam shot so I spent a bit looking through my cameras manual at the features :fightin:. Anyways here they are. Laser Diode: Nichia A140 445nm (purchased from Stonetek.org) @ 940mA w/AIXIZ Glass 445nm Lens...

from what I read they are run around 600mA in the Casio. I have the spec sheet right here that I printed off stonetek after purchasing mine but its a Engineering Sample specs so no lifetime... Just dont allow overheating and she should last!

Re: The "Blue Ninja" - 445nm DIY Creation those o-like modules really that much better at heat dissipation? I have my A140 running at 940mA and without any heatsink (Waiting on laserlands) gets hot enough to burn skin in 5-10 seconds! I did use AS5 on the threads of aixiz module and around the...

Thank you all for input I did finally get the piece of dust or whatever it was off the lens using a toothpick, but it did melt a spot into the window itself :cryyy: Its a bit better than it was but there is nothing more that I can do. Thanks everyone

ok thanks everyone so just to clarify by saying it still works fine, Is there any performance, Life loss anything degrading or actually improving>?

Just want to make sure umm wont that just scratch the heck out of it and make it worse? BTW it is already melted on there i believe (sure looks like it)

Not sure what Peta-amps means But i have it running at 940mA max

yes it is on the Diode Can Window.

Ok i had noticed that on my new 445nm build that there was a distorted spot in the middle of the beam that could clearly be seen. I though it was just the aixiz acrylic lens that I was using since it didn't show up till a few days after building it so I figured the lens Just started to melt...

Thank you very much I was feeling quite disappointed as this is my best driver to date and I felt proud of its layout, design and neatness. Yet you are the first to say anything good about it!:D Thanks for the post:thanks:

That is just the way i saw it done on some utube video a while ago. Thought that was how had to be done? is it not??

This is my latest circuit for my 445nm A140 Diode. I am posting to give ideas maybe to people looking to build a linear driver. I am also looking for any suggestions for next design (anything to add or change). Parts: -LM317t Adjustable voltage regulator attached to TO-220 Heatsink using...

ok, and whats the problem... I was just adding my method to the thread incase someone cam across it and was able to use the information. Was unaware that there was some thing wrong with this!

I just received my first AIXIZ modules ever... Anyways I got both mine apart no problem just used two pair of vise grips and two of those thick rubber pads that you use to open Jars lids and so on. I just put one rubber pad around each end of module fit vise grips around each side and twist...

Thanks for all the info on my driver! I did use a multi-turn pot after finding out the hard way how bad the single turn pot was that i originally used. The single turn pot only worked at the final 5 degree of the turn. lol So i removed that and replaced with a multi turn which worked out way...
