We'll start by placing the DC power jack. This is how we will attach outlet power supplies to the board. The jack is 2.1mm which is the most common size.
The DC jack can only go in one way, so its pretty easy to work with

Flip over the PCB - you can either tape the DC jack down or use a finger to keep it place.
Solder the three big pads that bring power to the board.
Make sure to use lots of solder! This is both an electrical and mechanical connection so it needs to be solid.

Next we will solder in the 1N5818 protection diode. Diodes only conduct electricity in one direction. This means we can use them to protect our circuitry from negative voltages - a top killer of electronics!
Bend the diode into a staple like so. Note one side has a white/silver stripe on it.
