If I order the https://www.survivallaser.com/DTR_20mm_Diode_Module_Host_Bundle/p556088_17737336.aspx It already comes with the contact board, right? Also I can order the G-2 lens from there for $8 and it will fit the 'NUBM44 450nm Diode In 20mm Copper Module W/Driver' which DTR sells for $25...

thanks! I chose ebay because I sometimes get 5-10% coupons off, then its cheaper, even though his ebay is about $5usd more than his website. But shipping on eBay is $2 less for international. SO that stainless steel host will work fine with the 20mm module? I have that exact same host on my 2w...

I built a 2w laser a few years ago and now that things are a bit cheaper I am planning on building a 6w+. If I get this module (https://www.ebay.com/itm/6W-NUBM44-450nm-20mm-Copper-Laser-Module-W-Driver-G-2-Lens-/182389461738) with driver, Diode and lens and use the host...

Well there has to be a point where light dims from the particles in air that it hits. Like a flashlight.

You're telling me the laser goes past the earth's Stratosphere????? :p How far can a 2W blue a ser go?

I've been using indoors only. But i am limited to the beam distance of my room that's why I wanted to use outdoors. Might have to find a deserted place to try at night. It's very silly how in australia a laser is the same category of prohibited as a gun. Makes no sense. But when I did archery...

Ohk. So looking at beam isn't going to affect my eye sight. Just checking before it's too late. Love the blue beam. It's so cool to look at.

Is it bad to point the laser at a wall about 2 meters away and look and or without the glasses? Does it damage your eyes in any way, considering it's and white wall and there is no beam refeito to the eyes.

I have a small tripod, just need to find some sort of attachment that can hold the laser and attach to the tripod. BY THE WAY the photos were taken with just a Samsung S5, nothing special. I did a solder melting test, and it worked really well. Very fast, was surprised.

Just did the electrical insulation tape test. It cut all the way through in less than 2 seconds. Tried a silver one and it just caught on fire. Also did the candle lighting, that took a while until it lit. About 10 seconds. How much can we rely on these eagle goggles from the 450nm light...

Here are the photos Assembled In my room during day At night inside room Outside

Its night here now. And it lite my whole room. Tried outside and WOOOW, its a light saber!!! its insane. Definitely can see a beam thats incredible. I might have been wrong. I did a few tests for like 30 seconds, and the head was just slightly warmer than the rest of the body. I think its fine...

I hope thats not what mine is like :( Too bad I don't have a way to measure the output.

When i say heat i mean i can feel a difference between temperature in the head and the tail. Nothing like i can't touch hot.

Hahaha, ill try not to... I want to see this thing at night! I can feel the heat on the stainless steel body, and I'm only using 10 seconds at a time. Whats the duty cycle on this?
