would he be able to use a less powerful laser just as effectively if he painted the end of the fuse black?

Okay awesome! Thanks for letting me know. I'm going to build that dummy load and save it for a later date, but use a driver that is preset for my first build. I have learned a lot. Thanks again to everyone for explaining everything so well!

Wow, thanks for the circuit diagram. I'll build one and save it for later. But I think I may go with the preset for my first build. Is it an absolutely terrible idea to skip the test load step? What are the odds that it will break my diode if i don't use a dummy and just hook up a normal rckstr?

So its a linear driver, which means the current it provides cannot be changed. And buying a driver (it looks quite a bit smaller than the rckstr) that is preset will guarantee that it won't kill my diode and start working immediately. And the capacitor still has to be discharged right? and...

I like the one from modwerx shop! so that one will hold a aixiz module? also, is there any way to set the current on a driver without a dummy load? I thought maybe I could connect the driver to the diode and it work right away?

Well what does work. And I like the card explaination, that shows how much I'm concerned about a host haha.

Anslem: That is really what I expect mine to look like. I don't really want my first one to be a flashy torch or pen style, I want simple and can get the job done haha. Leodahsan: I think I'm going to stick with the blu ray because it seems to be the easiest to do and there are many different...

What types of metal are ideal? and do you have any suggestions of heatsinks to start with for a first time build? I'm thinking the host is less important that the actual construction of the piece.

That word is so deceptively simple, host, eh? haha. Thanks for letting me know what it is. I understood the diode to be a pretty tight squeeze in the module. Does that mean you attach the heatsink outside of the module?

I don't know where to begin with heatsinking. There are so many different types for many different applications... Do you have any recommendations on where to start? Is there any common items I may be able to salvage them from or a website I may be able to grab one from? I'm trying to be very...

My budget isn't exactly infinite, but I am willing to put a few dollars on the line and learn from my mistakes if need be. I've been looking at the PHR-803T and I believe that I will be working with that one. Is the forward Voltage in each one different, and how do I go about doing that? You...

So I'm new to the whole laser business, but I hope to not be in the upcoming weeks/months/year. I am an Engineering student who has always been fascinated by sciency stuff and lasers are right there. I have a pretty good understanding of basic circuitry and I've been doing a lot of reading up...
