I decided to go do some research about how to properly interface with AC Power. What I ended up doing was disassembling two wall plug-ins and testing a RAC03-05SK. The testing of the RAC03-05SK will be discussed in my pump house monitor project.

Disassembling the wall plugs (a phone charger an some other charger) three common things stood out and that is:

1. Compared to the traces I made the traces in those chargers are very large. I think this might be just for safety purposes (they don't have to be that big but they had room so they made them that way anyways), but I am not sure.
2. Both had more through hole components than I expected them to have. 
3. Both had a large component with yellow tape around it that I did not immediately recognize. It turned out that it was the very important component that is the transformer.

Something that was not common between the two was how they connected to the wall plug. The phone charged just had two metal contacts that pushed against the wall plug creating the contact. That one is shown below:

The other one had a wire connecting the plug to the PCB, and each side was soldered on. That is also pictured below.

Another difference between the two is that one was obviously cheaper than the other and I found that interesting.

Below is a video of me disassembling these chargers:
