Step 3: Test Your Radio
Seriously, test your radio out ahead of time. Better you see if it's working now than after you take it apart.
You can also test out your AAA batteries to see if they're working and if they'll play nice with your radio.
Now you may notice those little white speakers, also from the dollar store. They suck more than the cold vacuum of space. I ended up not using them with this project and instead used them to entertain my cat.
