Amazon is selling a $35.99 DIY Bluetooth speaker kit that lets buyers, including children learning STEM skills, assemble their own working wireless speaker at home. The kit requires no gluing or soldering, as pre-fixed wiring simply snaps together into an acrylic shell, making it accessible to hobbyists, families and music fans looking for a hands-on project or gift.

The finished speaker measures around 6 x 3.2 inches (6 x 4.9 inches with its handle raised), features 20 music-reactive LED lights and two sound cones, and connects via Bluetooth 5.0; it comes in four colourways and has earned a 4.8-star rating from reviewers, though batteries are not included. Amazon also offers a cheaper $16.99 alternative that combines a wooden FM radio and mini Bluetooth speaker in a cat-shaped design, aimed at children aged 8 to 12, though some reviewers suggest it suits slightly older builders better.
