introduction to soldering and making a 5v power supply

Soldering a PCB

I used a soldering iron to solder 20 points of various components onto a PCB. When soldering I made sure to over the entire pad without touching any other pads, and also making the solder cone shaped and shiny.

Splicing and Soldering wires

In this exercise I used a wire cutter to cut and strip about 3/8 of an inch off the insulation from each end of four equal size wires. Once the insulation was off I soldered each of the pieces together then used the soldering iron to heat up and shrink the heat shrink.

Power Supply

Finally, I assembled a 5V power supply. First, i cut off and discarded the plug and then stripped off about 3/8 of an inch of insulation. I then soldered the wires onto a two pin plug, and added heat shrink to cover up the exposed wires.
