DIY Mini Speakers: Upcycle Red Bull Cans

Transforming two Red Bull cans or similar beverage containers into passive mini speakers with a metallic resonance, ideal for enjoying classical music, is a creative and engaging project.

Begin by acquiring two cans and preparing them for modification. Utilize marker ink or colorful paint to dye or decorate the cans as desired, ensuring a visually appealing result.

Once the cans are prepared, source a pair of 3-ohm 5-watt speakers to serve as the audio output. These speakers will be carefully integrated into the cans to create the desired sound output.

Next, disassemble two firefighting emergency light control boards to access identical interfaces. These interfaces will facilitate the connection between the speakers and the audio source.

Secure a pair of red and black wires and solder them onto the control boards to establish the necessary electrical connections.

With the wires prepared, proceed to drill small holes in the bottom of each can to accommodate the wiring. After threading the wires through the holes, use adhesive to firmly secure them in place.

Carefully solder the speaker wires to the control boards, ensuring proper insulation to prevent electrical issues.

Align the speakers with the holes in the cans and affix them securely using strong adhesive.

By following these steps, you'll successfully create a pair of unique and functional mini speakers with a distinctive metallic tone, perfect for amplifying your favorite tunes.
