Hi! I am trying to build a 7-color box (Red, Green, Blue, Yellow, Cyan, Magenta, and White) with a 200mw 650nm module, 100mw 405nm module, and a 50mw 532nm module with a 6000mAH 3.7v 18650 for each. I was afraid that the output ratio was off, but someone suggested I used potentiometers to adjust...

RedCowboy, what ratio of outputs did you use?

Wow! This is the first white I've seen with a higher green output than red. I'm trying to make a 7 color box including white, however I'm buying a 200mw 650nm, 50mw 532nm, and 100mw 405nm for a 4:1:2 output ratio. I'm surprised that you still get that color with a 1:2:2 ratio. Btw, I think you...

I did a bit of research. Could I hook up my modules' wires to a breadboard with a potentiometer like this, only with a laser module instead of a fan (I do this three separate times: one for each module) If so, what kind of potentiometers should I use if I'm using a 100mw 405nm module, 50mw 532nm...

I don't have any experience soldering, although I just bought a 60w solder gun and a roll of rosin core flux to get me started. The only thing I don't know, which I plan to look up, is how to provide power to the driver if it doesn't come with the wires sticking out. Could I get 3 of these for...

So I could potentially have a laser like this if I use analog drivers? Where do I get them? I looked them up but I can't find a good source. Is it possible to get the 3 modules + analog drivers for <$50?

I keep getting an error when I click on the download link. Could you tell me what outputs you would choose? Again, I just want 7 distinct colors. Could you also tell me 2 ideal outputs of red and green to make yellow in case this project fails and I want to reuse some of the parts for a yellow...

Thanks for the feedback. The post you included was very helpful. I'm considering the 4:1:8 (Red:Green:Blue) ratio. Do you think I could get away with a 20mw Red, 5mw Green, 50mw Blue. I don't mind if the color is slightly off, I just want a 7 color box instead of 4 colors + 3 other shades of...

Hi! I'm planning to create a 7 color laser box (Red, Green, Blue, Magenta, Cyan, Yellow, and White) similar to this one. I created a small diagram of how I am going to place the diodes and dichroic mirrors, but I need a little help on the output ratio. Ideally, I would like >100mw of output...

I was a bit hesitant before purchasing the laser, so I decided to browse LaserBtB a little more. I'm curious, would This (2000mw) do This?

Wow, I didn't know that! Does the IR filter have any affect on the visibility and/or burning capability?

Just pointing around and a little burning. I guess I will go with the 200mw one. Also, what is an IR filter? Is the $1.61 worth it? (I obviously wouldn't mind paying +$2, I'm just curious to what the IR filter actually does)

I'm likely going to buy a LaserBTB. I have narrowed my choices down to PL 520nm 532nm 100-1000 (200mw) and HL 532nm 50-300 (300mw) Which should I choose? I prefer the advanced 200mw one that comes in a briefcase, but for $20 more, I can get a 300mw without a fancy case and professional look...

It was in my original post, but I want something less than $200. I would prefer something green and, from what RedCowboy mentioned, I want a handheld. Some of the options I gave in my previous posts were what I am looking for, however, I don't see any product reviews and I would rather have...

I'm not very crazy about the host, but I would enjoy something like this (third image) if it's not too much. As for the color, I chose green because I heard it is more visible than blue and the beam is thinner and better for burning, but if you can find a cheaper blue one with a higher heat...

Done a little more researching... I have heard lots of satisfaction from buying off of people who build lasers in these forums. Anyone know some trusted sellers I can contact? I also found two other options on O-like.com: 5 in 1 sky star High power 400mW Green laser torch/focusable [OL-G400-S] -...

Thank you for that. So if I wanted a >100mw green handheld laser, which site(s) should I be looking at? And if possible, which product would you suggest? Again, I want it to come with the batteries, a charger, and glasses (preferably in a briefcase) which the eBay options I provided included...

Please, only respond if it can get me closer to buying a laser that comes with glasses to protect me. I don't want people patronizing me over a short statement which is now removed after RedCowboy mentioned the novice/youth that browse here. I have seen videos prior to purchasing the 303. The...

Just to clarify, I don't point lasers in my eyes for fun, I accidentally caught a few glances after pointing a 5mw at some wrinkled aluminum foil (I didn't intend to create that assumption). I deliberately asked for a pair of nm corresponding glasses/goggles in my original post knowing that I am...

Hello! I am new to the Laser Pointer Forums and I need some advice buying my first real laser. I have gotten 3 cheap 5mw Lasers Pointers (Red, Green, and Blue) on Ebay along with one 5mw 303 laser pointer. The 303 has a very visible beam in my basement and at night, and a slightly visible beam...
