Thanks Elite. I know that I have to be patient. It's just hard because of all the great things everyone is saying about this monster. I'm so excited to see it for myself. lol

Just a quick question, I'm doing a project and I need to know if this laser would be able to shoot through a piece of 3/16" plastic and cut 1/16" nylon thread in a reasonable amount of time without damaging the plastic window? Thanks in advance for the help, I'm glad I found this site!

I think you might need to explain what your talking about? It will cut (most) plastic and nylon but what do you mean with out damaging the plastic window??

Sorry, didn't mean to be unclear. I'm going to be building a box with something hanging from a nylon thread inside of it. In one wall of the box there will be a window to see inside the box and the item hanging by the thread, this window will be made of plastic, approximately 3/16" to 1/4", haven't measured it yet. It's part of a thing I'm doing for school, it's gonna be one of those chain reaction type things. What I'm wondering is, will the laser shine through the plastic window and is it strong enough to burn through the thread in say, 10 seconds? Or will it just damage or melt the plastic and not shine through to the thread?
I just need to know so that I can make changes to my project if I need to, before spending almost $200 (although I wouldn't mind having one of these builds for myself anyway ) Sorry about the confusion!

I got the night beam shots :3
And i did do a comparison with my DhGate "1000mw" greenie (koff... 123mw on meter, according to another member)

Also I applied a modified version of this guys idea:
Quote:
KAR
Focusing tip for anyone interested: Instead of putting a spring or tape on the threads of the lens, I made a round spacer out of aluminum that fits snugly around the threads and is .097 inches thick. When I tighten the lens down against the spacer it has a perfect focus to infinity. If I want to burn I just loosen it to sharpen the beam. This way I always know that the beam is focused for night pointing and don't have to worry about the lens turning while it's in my pocket. When making the spacer, it takes time to get it right cause once you get the thickness close, you have to literally remove .001 or .002" at a time till you get it perfect but for me it was worth it. What a great Laser this is.

Kevin
DhGate "1w" vs Yob445 1w+


Night shot


items used to make spacer: (metal sheet from Dead ibook, Super glue)


Spacer super glued to lens (I also applied super glue to the screw part of the lens as a way to make it harder to turn. But I made sure the super glue didn't bond the lens to the rest of the laser. To make sure its smooth, I used a pair of pliers to screw it in and out a few times)


Quote:
KAR
Each spacer would probably be slightly different in thickness due to variation in dimensions between lasers...therefore it is something you would have to fit to your own laser and can't be mass produced.
For my laser I only need to use one layer of metal (the sheet of ibook metal is quite thin)
But you can use how ever many layers of spacers you need~

.....sewper gloo +3+

KanoBox,are you out of your mind? under no circumstance do you ever point a laser(especially this type) at any part of your body and should always have safety googles on at all times.it sounds like you have already damaged your vision.Hope it is not permanent.btw,most any laser from dhgate(a couple sellers especially) are not only way under spec,sometimes they are not even the item advertised.
anyway,don't want to get off topic.I got mine yesterday(thanks yobresal).The package may not have been handled with proper care by my mailman.as a result mine did not work.before i even put the batteries in i could hear a rattling.it was the pos wire,it was no longer soldered to the leg of the diode.with this build if you have to open it you need to be extremely careful or it is very easy to break.so after i got it apart all i had to do was tack the wire back onto the diodes' leg,but the wire is short and there isn't much room to work.so i decided to desolder the black wire from the other leg and then i soldered a small 2 column pin header to the wires.then i soldered the female clip to a couple of 1 inch wires and soldered the other end onto the diode.now i can very easily take out the heat sink simply by unscrewing the retaining ring and can clip/unclip instantly.
It is working good now and the only other thing i needed to do was tighten up the focus adjustment(but that isn't anything).thanks again yobresal for everything and the super quick shipping
