I am moving and I recently dug up an old relic. It is a bulky 300mW 520nm laser. pics below.

My university is quite conservative, so they're lax about students having bows, knives and even small firearms on campus, so long as they're registered with both the university and Police department, and inspected for a 24 hour period. according to their definition, lasers are not *technically*...

Looking to get my second high power greenie laser, in either a 520nm diode or a 532nm DPSS. looking for a pointer or a portable laser. Send me an offer via PM, or at my email: tuskiomisham@gmail.com Thanks!

an Alibaba seller seems to have fat-fingered some diode prices in. According to the list price, they're selling 1W 520nm diodes for 50 cents a piece. that's about 0.27% of their normal price (estimated at 185$).:wtf:. I've sent in an inquiry for 100 of these diodes for 50$, Just wondering if...

Hey, I wanted to start a thread for laser bucket lists, lasers that you could realistically own in the long run. For me, these are lasers I'd like to own before college: 5mw RGB laser pens. Something I could let my friends play with without having to worry. 50mW 532nm dazzler. 1W 405nm...

Hello! I want to buy 3 modules, one red, green, blue, all around 5-20mW for a project. However, I want these modules to be able to have one common power source (1 power supply) for the three diodes. I do not mind the wavelengths, so long as they are indeed RGB, and non-gas.

Hey, I wanted to compile a list of common household appliances that you can salvage diodes from. If you know about where to get these items, i ask for your grace in sharing. Uv: TEA laser (338nm) 405nm: Blu-ray burner 445nm: Projector screens 535nm: ?.? 520nm: Projector screens...

Linky link I cannot think of anything he did wrong, other than a small dustup with cowboy.... Did I miss something?

So, I'm working on a way to produce PCBs for small jobs, and I thought that lasers might be a good way to go, as etching seems to be very difficult from small traces, needed for many microcontrollers. I started by searching the absobance spectrum of copper, as the metal itself is very...

Hello, all. I'm going to be building a laser-guided yoga ball launcher. For that, I plan on using a web camera and a monitor to help guide the user. The laser's dot needs to be visible under good lighting (not outside), but must be less than 2mW, for safety. Because we're using a camera, the...

Hello, all. I'm going to be essentially turning my SF501B 405nm into a labby. my plan: quadrouple the wattage the wattage to 3.2 watts :eg:. note: this is purely for fun. I don't think i'd ever need a 3.2 watt laser for any reason. Here's how I plan to do that: The Sf501b host is a simple...

so, a loooong time ago, my laser from etian broke due to a heat failure :cryyy: these are the step i'm taking to fix it, and potentially upgrade it! first off, I'm putting in a vouch for etian's (TheJoker301) busines, they have truly high quality. :thanks: The case, which is aluminum, is...

I'm looking to fog up my room and do a nice shoot with some fog. Can we compare these? If not, i'll do each on my own time. Dry Ice + water fog (co2 fog) Glycerin fog (fog machine) Combustion fog (smoke) Fog (natural mist)

Hello, all. I am going to be purchasing some lasers soon, and want a basket for purchase. This will be useful for both me and other members for the holidays.:san: Budget: 600 USD What I want: 5 - 7 lasers, all different wavelength Only 1 UV or IR please If a laser is over 30$, please make sure...

Hey, I'm interested in buying a burner, but I really want one with a slim divergence. I'm currently waivering between companies, but Etian was great last time, so i'm leaning toward his business. I have a request, if you're listening, Joker :yh: Could you post pictures of each of your lasers at...

I want a nice beam laser for stargazing, but I want the beam to be clearly defined, and highly visible. I was wondering what the comparisons of the two are as far as the following: beam divergence brightness in daylight brightness at night (because sensitivity of wavelength changes at night) IR...

One of my friends started dealing these pointers at my highschool. I trusted him to sell them to (more) responsible kids. I was wrong. So this asshole had his out and was flashing without the lens (beam) in the classroom. Now some background, i'm 18, 6'10, and 210lbs. I'm not buff, but i'm...

first off I've had this laser for 3 hours now, I know. So I got one of joker's high quality lasers in the mail. I ordered the 405nm purple 1 watt laser. been waiting a whole month for this :) I open the envelope, take out the box, to find a laser, assembled and ready to go. My first thought to...

Hello, this will just be a sort of engineering log for anyone who hopes to make the same thing that I do. What I want to do, is create a copy of this, but with lasers instead of LEDs. My goal is to have the thing paint lines on the walls of red, green, and blue. first odred of business is...

Hello, all. I recently have been poking around on this thread: led orb. I want to make one myself, but with red green and blue laser diodes. I'm having trouble deciding on a good class, and need input. 1) I want everything to appear at the same brightness. I want to do this to have the maximum...
