That thing will heat up incredibly fast. You will definitely need a large heat sink for it. They're are some unused hosts floating around the forums that you can definitely put an offer on. Especially if they're a host created by an artistic genius called "Eghemus". That man could make the most amazing and creative hosts you could ever imagine. They were great for larger lasers as well. Sadly he is no longer making them so we are left out here to fend for ourselves. I'm sure someone would gladly sell you one for the right price.One last question (probably, at least for a week or two) do I need ot get a host? or can I instantly build this into a nerf gun or something? (I want to make it partially into a cosplaying thing, and spray painted nerf guns are all the rage)
What does "can I instantly build this into a nerf gun" and "want to make it partially into a costume playing thing" mean? What is it you want to do with a functioning laser?One last question (probably, at least for a week or two) do I need ot get a host? or can I instantly build this into a nerf gun or something?

nice thread, This is very useful, thanksWelcome to the forum!
First of all - I would not recommend starting out with something like this. The best way to start building lasers is with single diodes. You have to walk before you can run.
But if you decide to try and run first - here's a link to a diode array more powerful than the one Styro used. Nichia NUBM08E 450nm 36W High Power Multi LD Bank Blue Laser Diode Array | eBay
If you overdrive that array (5-6A per diode) you might be able to achieve 50W; thus you would need two arrays. This is going to set you back $3200, and then heatsinks, drivers, and the like will cost even more. The whole project will likely cost you $5000+, which is... expensive.
In addition, consider the fact that you have to handle 16 separate beams with something like that. This means that if any one of those 16 beams reflects off of something, it could blind you instantly. And it could potentially kill you if you use it wrong.
Assuming you insist on making a multi-diode laser, it would be best to wait until NUBM08E diodes are available as units, and then use a PBS cube to combine two of them. That'd give you 20W of power, which is more than enough for some serious destruction. In the meantime, you may want to try your hand at lower-power single diode builds.
