Anyone seen this website before? It seems to be a new LPF sponsor. They offer the exact same lasers as LaserBTB does. High Powered Laser Pointers | SKYtech Lasers Their website more professional than LaserBTB's imo, but other than that I don't know anything about how good of a company it is.

So, it seems the government of my country is now trying to place lasers on the same levels as owning illegal weaponry such as guns. Their reason for this is that people are pointing on aircraft taking off or landing at the airport. I'm so done with this shit. Can't they for a change throw...

New members often ask simple questions that have been answered countless times already. They usually get pointed towards the search bar on the bottom of the page, or get told to read stickies. But what if those search results or stickies are outdated? They make another thread, asking basically...

I've been looking for an LPM for a while, and it seems ebay only offers heavily used Ophir sensors or they charge you an arm and a leg. I'm looking for a good LPM that reads up to >3.5W with a resolution of at least 1mW. Preferably with an Ophir sensor or something of equal quality...

Was browsing some stuff on kickstarter when I came across this: https://www.kickstarter.com/projects/skarp/the-skarp-laser-razor-21st-century-shaving?ref=video Seems like the biggest scam to me. A lower powered, eye safe laser that cuts through hair and lasts a month on a single AAA battery...

Recently I have been thinking of doing a NDG7475 520nm build, but this time I want to optically correct it. My idea was to simply expand the beam with a cylindrical concave lens first and then place a cylindrical convex lens after that. Now here's what I'm wondering. Will it be worth optically...

SOLD I thought I'd post this here since I hate dealing with eBay. If I'm breaking any rules then please let me know and I'll delete my post. For sale I have my graphics card, a Nvidia GTX Titan X. I don't play games too often anymore and I want to sell it while it still has value. I bought it...

So, as you may or may not know, Apple recently announced the iPad Pro along with the new iPhone 6S and a Apple TV. I've been very excited for the iPad Pro to be announced mainly due to me wanting something to replace my 3rd gen iPad with. Now, after it's been announced and the main features...

For a couple months now I've been wanting to get myself a 405nm laser. So, a couple weeks ago I finally ordered a 1W 405nm module from DTR. I've had this host laying around for a while now and wanted to put it to good use, so I decided to build the 405nm module in it. The build wasn't too hard...

So, yesterday late at night I was pointing with my lasers outside my window like I frequently do. Now, there's this road near my house where many people come across on bicycles, especially when it's saturday late in the evening. I usually hear the occasional screams and wow's when I'm pointing...

I recently cut the wires on one of my drivers too short, and decided to desolder them. The desoldering worked, but now there's a bunch of solder left inside the holes where the wires go. Does anyone have advice on how to remove the solder and solder in new wires?

Since I had some spare money left and already had a host, I decided to buy the NUBM07E diode and make this build. I had already built the laser entirely before I thought of taking pictures of it, so I disassembled it for as far as I could to take the pictures. First off I rebuilt the switch...

Came across this, thought it was worth sharing. Stephen Hawking Kicks Off $100M Hunt for Alien Intelligence More here for those interested

As I'm not really sure how to start this thread off, I'll just post my question right away. Is anyone willing to explain me how exactly I can correct the beam divergence and possibly splash around the dot of multimode lasers? I've been for answers on the forums lately, but I can't find much...

Alright, So I assume most of you here know this ridiculously famous youtuber 'Pewdiepie'. Well, it seems like he's another complete retard showing his lasers to millions of people while nearly blinding himself. While he does wear safety goggles, he has absolutely no clue what he's holding in...

~~~~~~~~~~~~~~~~SOLD~~~~~~~~~~~~~~~ This is my last MrCrouse host that I'm putting up for sale. It's a very sturdy, durable host and fits two 18650 batteries. It's already wired so building a laser in it is a piece of cake even for first time builders. I'd like 75$ for it. PM me for shipping...

This popped up in my recommended videos. Laser part starts at 9:25. This dude let's his 4-5 years old kid play with a 1W+ arctic as if it were a simple toy. Dude doesn't seem to care that even a slight reflection can mess up his vision for the rest of his life.

Close please.

Update: Every host has been sold. This is going to be my last sale thread for MrCrouse's hosts. I will be selling two Maces of Doom and another custom host. The custom green host has not been wired and the Maces of Doom have been wired. The Maces of Doom will be sold for 80$ each, shipping...
