Making a portable radio using a jerrycan is a creative and functional DIY project. Here's a step-by-step guide:

Materials Needed:

1. A clean plastic jerrycan (5-10 liters recommended for portability).
2. A small FM radio module (or an old radio circuit).
3. Speakers (small, battery-powered or low-wattage speakers).
4. A rechargeable battery pack (e.g., 3.7V lithium battery).
5. Switch (for power control).
6. Wires (for connections).
7. Antenna (from the radio module or a repurposed telescopic antenna).
8. Soldering kit.
9. Drill (for creating holes).
10. Screwdrivers.
11. Glue or epoxy (for securing components).

Steps:

1. Prepare the Jerrycan

• Clean the jerrycan thoroughly and dry it.
• Drill holes for:
  • Speaker grills (usually on one side of the jerrycan).
  • Switch (on the top or side for easy access).
  • Charging port (if your battery pack has one).
  • Antenna hole (near the top for better signal reception).

2. Mount the Speakers

• Place the speakers in the drilled holes.
• Secure them using screws, glue, or brackets.
• Ensure the speaker cones are facing outward.

3. Install the Radio Module

• Fix the radio module inside the jerrycan, using glue or a mounting bracket.
• Align the control knobs or buttons with the outside for easy operation.
• If the module has a digital display, cut a hole in the jerrycan for visibility.

4. Connect the Antenna

• Attach the antenna to the radio module and thread it through the antenna hole.
• Secure it with glue or a mounting bracket.

5. Wire the System

• Connect the speakers to the output terminals of the radio module.
• Wire the battery pack to power the radio module and speakers.
• Attach the switch between the battery and the radio module for power control.

6. Test the Connections

• Before sealing the jerrycan, test the radio:
  • Turn on the switch.
  • Adjust the volume and tune the radio to check the signal and speaker output.
• Fix any wiring or component issues.

7. Seal and Finish

• Once all components are working, seal the jerrycan with its cap.
• Use glue or epoxy to secure any external components (e.g., switch or antenna).
• Decorate the jerrycan if desired, using paint or stickers.

8. Portable Usage

• The handle of the jerrycan makes it easy to carry.
• Charge the battery pack as needed, or replace batteries if it uses non-rechargeable ones.

Tips:

• Ensure proper ventilation around the speaker holes for better sound quality.
• Use lightweight components to maintain portability.
• Opt for a solar-powered charging system for extended outdoor use.
