This is a Circuit Board Artwork that can be attached like a keychain. It is a musical jukebox can play 10 different music tones. Power using USB-C cable and use the buttons to choose the music to be played. In addition to the circuit board keychain, you will also get: keychain clip, keychain ring.

There exists a "capture-the-flag" style puzzle, where several text or "flags" are hidden in certain functions of the USB serial communication. This encourages players to explore the concepts behind reverse engineering a product design.

CircuitBoardArtist was created with the vision to spark passion for engineering education by blending in creative arts. Through circuit board artworks, I wish to explain electronics concepts through a series of educational kits in a beginner-friendly way. More illustrations and documentations are currently in the works, with plans to collaborate with educators as well.
