Reclaiming parts from broken/obsolete hardware

In order to make our Circuit Playground Express portable, we need to wire up a battery pack. We could buy battery packs online for about $3 each and wait a week for them to arrive. OR we could learn how to disassemble broken or obsolete electronics and get what we need for free, along with a bunch of other parts we can use to create something new.

For our next project, we need to find 1) 2-wire JST keyed connector.  It looks like this:

JST 2-pin connector and wires

The CPE board has a female connector (like the one on the left). We are looking for a male connector that fits inside it (like the one on the right). Many small electronics use JST connectors like this to supply power to internal components. Computers often power speakers and power buttons with JST connectors.

Another useful component is a battery holder. We can make our own, but it is also possible to salvage them from old toys and video game controllers. We need one that holds 3 AAA or 3 AA batteries to supply 3.5-6 volts. We can modify a 4-AAA  or 4-AA holder.

Here is a guide for removing soldered components from PCB boards.
