Yeah I looked up the beam visibility when I did my first build and it said that green and blue / violet have the best visibility and red has the worst. I am not a big fan of the red for whatever reason. I am really kind of drawn to the blue modules for this project. Of those I was looking at the...

Well my first build aimed to take a toy laser gun casing, put a module in it, and have a burning laser with a visible beam. The assembly worked perfectly, but I ended up with a laser pointer that didn't have a beam and didn't burn / pop balloons. It was the DX module in my previous post, a...

Gabe! These modules do appear to be what I am looking for (idiot proof ones) but the last 200mw I bought did not produce any of the effects that I was expecting, it was a DX 200mw 532nm module. With an adequate power supply, would the modules in the links you provided produce a visible beam and...

I took a look at the DTR shop, cool stuff for sure. A couple of dumb questions though: A lot of the 445-450 modules have outputs of 1W+. The only laser module I have worked with was a supposedly 200mw green laser that quite frankly isn't any stronger than a $5 Walmart pointer. I am intimidated...

Oh yeah. I could see that becoming unpleasant. Is there a section of the forum where I can locate someone? I would feel a little weird and hesitant just messaging someone to build me a laser module. If there is like a thread about "hi I'm bob I will build you a laser and I take paypal" or...

Thanks for the replies, I will probably look into the 445 as my money is a little tight right now, and I want to increase laser power as I get more experience. My other question is what kind of power supply would I need for a 445 module? Or will they have that information when I buy it?

Hey forums! I am to the point where time and money is going to allow me to start another project that involves pew pew lasers. The aim of my first project was to build a burning laser inside of a toy gun case. I was ultimately successful, but the module ws underrated and I basically ended up...

Yeah different sites but same glasses, I got the important part. Thanks for all of the info, I will look into tweaking the screw to see if it improves results.

I went with these Eagle Pair® 190-540nm Standard Laser Safety Goggles

Cool, I do want to build a blue laser at some point in the future, I just kind of like green. Quick question: I do have a pair of safety goggles, eagle pair, they completely block the green light from this laser but not the red dot of a standard walmart laser pointer. The goggles I bought were...

Hi! I recently completed my first laser build with some advice from fellow members, basically what I set out to do was achieve a green burning laser with a visible beam. As it stands, I just get the green dot and it doesn't burn. I ordered a 200mW 532nm Green Laser Module (3V 11.9mm) from dx...

Hi laser forums! I am a new user who stumbled across this site while working on my first laser build. I received some excellent advice from the members here and I was able to learn what I needed to correct my build and get the laser working. Now that I have some hands-on knowledge, I want to...

Yeah it turns out that my module either isn't very strong, or three AA batteries isn't enough for it. But it is working, I get a steady green dot and I have it closed up in its case. I will upload some pictures of the finished project. Even though this was my very first attempt at building a...

I am happy to say that with the advice from Pman about the button shorting and the loads of help from Lightning Stalker, I do have a pleasant little green dot shooting out of my module! I am going to wire it, piece it together, and upload some pictures of the build that will hopefully keep...

It may be a couple of days before I can really play around and see if I can get the build working, but even if I have to try again, you all have given me some great information about what to do and what to avoid. I will be giving rep all around for sure.

I will definitely look into getting better batteries for it. I was actually wondering about the voltage, if I get those cell batteries recommended, do I have to get batteries that offer exactly a 3V output? Would more overload it or would the driver regulate the extra voltage? Also, if you had...

Okay thank you, I am a bit busy at the moment with finals right around the corner, but I do have one more question: The module I bought said it was 3V and for power, I had two AA batteries in series, which should be 3-3.1V. This sounds incredibly simple but that should be a proper power source...

By brass module, you do you mean the outermost casing or the positive prong? I unfortunately get the feeling that I forked it up pretty good by getting solder-happy and not just testing the wires to it first. I was also really confused as to where exactly the wires went, since I wasn't...

Yeah sorry for the lack of info, I was pretty tired when I made the original post, let me elaborate a bit. I was expecting the wires to come attached to the unit, so I really kind of jumped the gun with putting it together, excitement got the best of me. I did not test the module first, I...

Hello laser forums! I am very new to what I am hoping can turn into a great hobby involving lasers, it is a fascinating technology. The short version is I am a computer sciences major and I was recently inspired to build a customized laser gun using a 200mW 532nm Green Laser Module from DX. For...
