Raise your hand if you recognise the following view: It's the view from the top of the hill in Greenwich park. It looks slightly different at night: (Not my picture) See that almighty green line? That's a five Watt laserscope, coming from the Royal Observatory. Well, guess what? My sister...

A while ago I was playing Populous: The Beginning with 2007Revolution, Steve84 and Chezumss and at the end _2007Revolution suggested I make a thread about it, to see if anyone else would like to play. It's a God-sim so you convert followers, get them to build a settlement for you and increase...

For a school project I have built a 50mW red spirograph and a 30mW green liquid sky projector. This thread, at this stage, is really a work-in-progress but I will be continually updating, answering questions and taking and uploading more videos and\or photographs as necessary. I will have a...

Please alert me if i've done something stupid and not used the search bar properly, but i couldn't find anything. I need an SF-AW210 diode shipped to Croatia. Does anyone have them in stock? Thanks in advance (seems to be how i finish all my threads...)

Everyone post pics of some food you've cooked, or eaten recently. Then wait 'til you're hungry and look through the thread and salivate uncontrollably. Here's what i had for breakfast\lunch. Bacon, egg, sausage, mushrooms and pancakes. Tbh, the mushrooms weren't so nice. The rest was good...

Here it is, my first build! As you can see, i used the highest quality of parts money could buy. It uses the red\IR diode from a PHR sled in a stock Aixiz module. I even screwed the switch into the side... :crackup: Beamshot: Oh wait, what's that? No beam? :shhh::shhh::shhh: I was hoping...

Edit (as in post #20): That's the end, everyone! Thanks to all those who took part, by voting, submitting entries, helping me out at the beginning with the decision making and, in the case of Jayrob, for donating the prizes. Well done to everyone that entered. Your hosts were all amazing! And...

Host of the year award for 2010!! :D Submit your favourite one of your builds with links, pictures or videos and stick 'em in this thread. Next Friday I will collect up all the submissions and start a poll in another thread in which all the participants can advertise their laser as best they...

My understanding atm is 473 is used in some projectors and 589 and 635 have no uses outside the hobby. Am i right? Also, this is for an essay and i'm going to need to source people that give me info so if you're happy to be sourced put your first & last names and your relation with lasers (e.g...

As a part of a school project, i'm building a three-peice laser lightshow consisting of a liquid sky projector, a three-motor spirograph and something of my own design in which the beam of a laser is passed through two rotating diffraction gratings. But i don't trust myself soldering to diodes...

Sorry about my other bullet-point review. It was pretty terrible. Totally re-done it now. First, i'll talk about the ordering process. The first thing i had to do was create an account at DinoDirect. Obviously. One good thing i noticed was that they corrected me on errors as i went rather than...

I have the O-Like 200mW focussable waterproof. Whenever i have tried it it has seemed waterproof, but i've read in various places that waterproof lasers are problematic in that they develop spots that get bigger over time, and in turn increase spread. When expanded the projection was already...

Yes, sorry everyone. It's another of these threads. Welcome to focalprice.com | The lowest Price for DS R4 lite,PSP Slim,Genuine Earphone,SONY EX71 EX082，PS2,Macbook Accessories etc. or www.rayfoss.com ? I far prefer the host of the gun-style laser, but I'm worried it'll be crappy quality...

Alright. I'm doing a peice of Physics Coursework for my A-Level. It's worth 40/300 marks so it's quite important and I need some help, and probably will throughout the process of writing it so I'm starting this thread. Every time I encounter a problem I'll post it in here and hope (possibly in...

Just wondering. Fire is my other potentially destructive hobby. Basically i like anything that's a bright light in the dark. Anyways, i like discussing my projects with people that are interested, but my Physics and Chemistry teachers aren't anymore and you guys seem (largely) to be pretty...

I saw an advert they put out as a Promoted Video on YouTube. Their prices are verging on the ridiculous. Here's the offer that interested me: High Power 30mW Green Laser Pointer Pen (Executive Edition) The way that they're able to detect that i'm living in the UK and then able to convert all...

tl;dr My laser stopped working after being dropped. I've tried repairing it by stuffing aluminium foil into everywhere where there might be a loose connection with no luck. Can anyone help? Today my laser dropped out of my pocket and hit a hard floor, then didn't work anymore. It's a FocalPrice...

I'm pretty new to lasers, and hoping to get at least a little more experience before i attempt anything like this, but it's a fantasy. My old cellphone has an LED torch that I can turn on & off using the phone. I was wondering, if I were to succeed in yanking off the cover protecting them...
