Hi folks, I've got an unusual phenomena I've discovered involving a polarizing filter for photography. I thought a video would do a much better job of explaining the question than text would, so I made a quick video. So obviously this filter can't be JUST two polarizing filters, but what do...

CLOSED Howdy B/S/T browsers, I'll be putting my amber laser up for sale, I just don't use it much and I could be using its value in much better ways. I'll be selling it at a pretty huge loss, here's why. Aesthetically, it's got a couple scratches and chips in the black enamel. Other than that...

CLOSED Hi browsers of Buy Sell Trade! I've decided I'll sell my 100mW rated 473nm Pl-E Pro from Jetlasers. Nothing wrong with it, I just believe it could use a new home where it could get more use and appreciation. No point in me hogging this beautiful laser when someone else could want it...

Preface Ladies and gentlemen, oh man it's so good to see you again. It's been a minute, let me say that. Even though I've been away for so long, I've been watching from the shadows as things like the Sci-fi lasers drama unfolded, rep system revolutions, as well as members coming and going like...

Hallo So, today marks exactly one year since the first day I joined LPF... asking a silly question I easily could've searched up and learnt more about instead of starting a whole thread. BUT, later that day I made a welcome post, saying I'd try to be an active and useful member of the...

Thanks to my sister who doesn't know how to use our 30-year old oven, she hotboxed the whole house and made it smokey. Probably gonna stop waiting for times like these and fire up the fog machine from now on.

Hey community, Recently I thought up an idea for a host. Following the tradition of the men in my father's side of the family, I got a thing for woodworking. Back when I was young(er), I used to do a lot of pen turning, where you get a blank of some pretty wood or acrylic, drill out a hole and...

Jetlasers Pl-E Pro, 300mW at 532nm! More aluminium, more better! Welcome to my review of the Jetlasers PL-E pro! I will try to explore as many factors as possible, so if I miss something, don't hesitate to let me know ;) Part 1: Shipping My order was placed on the 2nd of August. Order was...

The First White Laser - IEEE Spectrum Duh heyul? If scientists perfect this, does that mean we could in the future get commercially available full-spectrum diode lasers? Am I reading this correctly? Discuss!

So, as I've mentioned, good ol' Questzacoatl gave us Edmontonian laser enthusiasts a gift, blowing in some what we believe to be is forest fire smoke. Couple that with Amazonian levels of humidity, and you get, well, the title :D If you have any requests, do ask please while the night is young...

Hello LPF, it's been a bit since I started a thread. I want to show you guys something I've known about our money here for a while, but I thought it had been shared before. I guess not! Our polymer plastic bills here are pretty neat: Aside from being rainbow, waterproof, holographic, and yes...

http://youtu.be/3JgVYZ2aWC4 I'm sure this has been seen before, maybe even shared HERE before, but I wanted to share this video that kinda made me smile. It's from, well, not the 21st century, and they're talking about potential uses for lasers, back when they were a newborn technology. What...

Survival Laser Red Laser Parts Bundle, 300mW @ 650nm UNBOXING TIME!!! I'm super pumped, my laser parts bundle from Survival Laser arrived, and I can't wait to open it. I haven't even seen what's all inside yet, so you'll be along the journey with me :D Part 1: The Unboxing The package...

Hey everyone! Here I have a little show n tell/story for you guys! So recently, I started investigating how lasers are put together, in anticipation of an upcoming build. In my opinion, the best way to learn about something is by either metaphorically, or literally, dissecting it. By taking it...

Hello everyone! :D I wasn't intending to post in here or talk about myself a lot, but I then found out just how open and accepting everyone is here! My name is Gabe, and I am in Edmonton, Canada. I'm only fourteen years old, which is the reason why I wasn't gonna talk about myself much (I have...

Hello LPF!:bowdown: While this is my first post here, I have been lurkin up a storm over the past few years. A already have a pretty decent (but I guess relatively small compared to you guys :p) collection of handheld lasers, of all the colours of the rainbow! But I want to get started in...
