Nice! I'm glad that worked out! You should be fine with the safety aspect as long as you hooked everything up correctly and in a sound manner. You are dealing with 12VDC at .5A so you don't have a lot of power to cause issues here. That said, there is always a danger of electronics melting down and causing fires. An electrician is who you should seek for answers about the safety of anything electrical you have made before trusting it with your or your families lives. Soldering connections and using wire nuts wrapped in electrical tape instead of just twisting wires together and wrapping in tape are good first steps in making sound connections. Always build strain relief into your system as well. Make sure the cable is securely attached to the project box and not just attached to the components. You want any tugs on the cable to tug on the box, not the component connections. Again, you should get an electrician's opinion on anything you have created before using it.
The white stuff is probably dried cyanoacrylate (super glue). Whenever it dries it vaporizes, then the vapor settles on things nearby. You can place the glued components in front of a fan next time and the fan will carry the vapor away instead of it being deposited locally. Rubbing alcohol can remove it. A few months ago I glued the halves of a hamster ball together as it kept falling apart (yes, I left the door portion unglued). I had forgotten about the vapor problem. My daughter brought it in to me the next day and we could see all of the finger prints left on the inside of the ball since the vapor deposits brought them out. This technique is used by forensic scientists to get finger prints off of surfaces and was pretty neat to see in action.
