Building a BOOMBOX - From Simple Speakers to Bluetooth

About: I am a researcher working on development of optical atomic clocks. Electronics is my hobby since childhood when my uncle was bringing me old phones to play and take apart.

In summer young people like to spend time outside playing basketball, practicing in a skatepark or hanging out on a beach. Listening to a music seems to be very important. Mobile phone speaker can play music, but it is not very loud. A solution is a BOOMBOX. Building it stimulates young people to get acquainted with electronics.

  • Start with a simple one based on PC speakers and toy rechargeable battery.
  • progress with an improved speaker and amplifyer.
  • add Bluetooth receiver to enable wireless connection
  • add low battery voltage monitor/switchoff.

Description of these steps is in the attached pdf file.
