Bluetooth speakers

A tech project demonstration shows broken DC motor gadgets and Bluetooth speaker toys taken apart, checked and repaired using scrap components. The hands-on teardown-and-fix format has drawn strong interest, with viewers following along as old electronics are opened, diagnosed and restored to working order rather than thrown away.

A user with a six-year-old Philips television has described frustration with the awkward interface for switching audio between the TV speakers and headphones via a Sennheiser transmitter. They solved the problem by using the TV's optical audio output with an affordable Toslink Bluetooth adapter, and shared the workaround online.
