Can a mod come in and help?

Geez seriously I didn’t think asking for some help would come to this. Besides if I do build a 505nm laser I’d just get it from lifetime17 here. thanks to the people who have helped me

ooh can i get one?

I've got a good supply of 18650's salvaged from a couple vacuum battery packs, and only 3 pointers to maintain so far, but if the diode I'm looking at is only around 35mW, then one of them should do fine? Also I recently received a boost converter from one of my Aliexpress runs, so maybe I could...

Good idea, but I think I’ll still do what I can to research it and maybe I’ll try to ask DTR just to verify if they are case positive. Say I do buy the module, and I find a non-destructive way to power it, what voltage am I going to be working with? Also I’ve heard that the AMC7135 is a good...

Hmmm so then I’m guessing that my best options are going to be to build an unconventional driver, and get the module from DTR’s (I actually have seen this diode in his shop before this) or pick a new diode or do a lot of learning

Hey guys! I recently noticed some cool looking 505nm diodes I have wanted to build a laser pointer for a while now, and when I came across this, I just had to do it! I already have two red 200mW pointers and a 405nm violet one (same power, also my first one), and so I have a bit of experience...

cool! i have always wanted to build synthesisers like that

no, like a 6 piece oscillator right here by sam battle really small, with an adjustable knob

I'm trying to build a oscillator/synth

yeah... I just went ahead and got a 12v power supply from the thrift store thanks for the info, and I think ill also get a boost converter module too. :)

I'm trying to get a steady stream of 12 volts for a project I'm working on, and I am too broke to buy a variable power supply, so I found a 240v to 9v wall adapter, but I want to use a capacitor to step it up to 12v. What capacitor would I use, and could I combine a 5v power supply to get it to...

so what your saying is that i'm not advanced, and i agree with you on that, but i cant buy scary lasers?!? but thanks

that helps a lot, thanks also, what kind of host or battery or what would be able to power this thing, to make it into a pointer?

i pulled a laser diode from a dvd RW but i have no idea how to power it. can anyone nerdy help? here is the diode: and here is some of the optics / host anything helpful would be great thanks
