In the event of a major disaster, it’s always good to have a radio on hand. You might think that your cell phone is going to get you through a crisis, but if it’s something on a large scale, such as an earthquake, you might have trouble getting calls through. Generally, you can flip on your radio and find some sort of up-to-date information on what’s going on. But how many of you actually have a radio that’s battery-powered? And how many of those device can you recharge without a wall outlet? If you’re in need of a rechargeable radio, why not spend $3 and make one yourself?
This excellent guide shows you how you can turn an FM radio, a pair of solar garden lights, some mini speakers (or headphones) and an Altoids tin into a solar-powered radio. It only takes around 45 minutes or so to complete. The only skill you’re need is knowing how to solder, and there isn’t too much of that involved. Even if you never need to use the radio in an emergency, it’s still a fun little project.
