So I am very exited I just got a bunch of stuff to make my XY laser scanner. I thought maybe after seeing it I would know better what I am doing but not so much. Some stuff defiantly does make more sense but here are pictures of what I got.
Here are my galvos, you can see the wires coming off of them that I plugged into this
I am almost positive that the wires from the galvos are supposed to plug into here so thats what I did.
Now I am not too sure about this one at all, I think this might be an amplifier or something. So I plugged the amplifier into the same thing I plugged the galvos into. (Makes sense I would think)
Now here are a few wires I got and have no idea where they plug into

Here is the DAC (I believe) so I plugged the DB25 into it because it fit but I am confused because it also came with a usb. So am I supposed to plug the usb into my computer or the DB25? I have no idea.
Now here is the side that the usb plugs into but why does it have an rj45 connector? why would I ever need to plug in a rj45 connector? Also I never got a 5V DC power connector so I assume I will have to buy one of those right?
And then Theres this. The 50mw laser....... question is how do I plug it in?
This is what is connected to the 50mw laser
Now for my 100mw laser. I see the laser, I see what I assume is the power supply for it. But then there are just 2 wires that I need to connect to something. You cant really see in the picture too well but thats what the blurry thing is in front.
I know I have a lot of questions but I would really appreciate if some people can answer just some of them.
Thanks again
