Section 2: Power

The last section that you did was the first step: adding the DC power jack. Now that you've gotten a little more familiar with soldering, we can finish it.

Overview

The LameStation is powered in one of two ways; using the on-board 4AAA battery pack or an external DC power supply. You do not need to worry about conflicts between the two. The LS automatically switches between the two sources using a shunt switch in the power jack.

The battery pack is a large, plastic obstruction to everything else you need to assemble, so this is one of the last items to go on the board, much later.

You will be introduced to a few things here: resistors, capacitors, and diodes.
