This project features a battery-powered music box with a custom 3D printed figurine. The box is intended to be a portable music player with a charming and interesting design. The primary features of the box are listed below: -Can play two pre-programmed songs from a micro SD card for over three minutes. -Contains party lights with adjustable color and intensity levels. -User can record up to 20 seconds of audio and then playback their recorded audio. -Has a Donkey Kong design theme with an aesthetic, lightweight enclosure for electrical parts. -Contains a custom 3D printed Donkey Kong figurine that spins when music is playing. -Powered by two 9V batteries. Critical technologies implemented by the box include embedded systems and signal processing. The box contains an Arduino UNO that performs the embedded tasks required by the box's design. The user interacts with the user interface by pressing buttons. The UNO responds by reading the button press and performing the corresponding task. Inside the main housing is a custom PCB. The PCB houses the audio circuit responsible for performing signal processing on the audio signal coming from the UNO and the microphone. Audio output is amplified and sent to the speakers to be played as music. Audio input from the microphone is inverted to the proper reference voltage level and then sent to the UNO to be recorded. Some challenges the team faced included the limited memory of the UNO, as well as the limited resources available for testing and physical integration during the COVID-19 quarantine. The memory issue was resolved by having the Arduino communicate with an SD card over SPI and storing the songs in the .wav file format on the SD card. Possible areas for future development include improving the quality of the audio playback and the sensitivity of the onboard microphone. The team also would propose a redesign of the PCB, which would include a ground plane for improved audio quality and the use of surface mount components to reduce space used by the board.
