1. Snip the wires going to the solar panel. Depending on your solar light you can either pry it out with a screw driver or push it from behind. I used a nail to push from the underside. The glue they use isn't very strong and the solar cell is quite sturdy.
2. Test your radio. You want to do this now because it's kind of hard to return once you have gutted it. Trust me, I tried.
3. Unscrew the radio back and remove the radio's circuit board and battery holder.
4. Place all of the parts into the Altoids tin to get an idea of the layout. For example, will the solar panels fit or will you need to place them on the outside. Or where the headphone jack should go.
5. Once you have the layout down you can then decide where to drill the hole for your headphone jack.
6. Since this is an emergency radio we want to get the most out of our solar cells. To do this, connect them in series which will double the voltage but keep the amps the same.
