This week, I focused on researching suitable lithium polymer (LiPo) batteries to power an amplifier and reviewed the code for a chassis kit sourced from Amazon. The aim was to ensure compatibility, efficiency, and safety in integrating these components into our project.
After looking at LiPo battery models and specifications suitable for powering the amplifier and analyzing battery capacity, discharge rates, and form factors to meet project requirements, I settled on 2200mah 3S 30C LiPo’s to power the microcontrollers and chassis motors. For the speaker and amplifier I chose 1500mah 4S 120C LiPos to power the speaker magnet. After reviewing the code that came with the chassis kit it looks like the vast majority of the work has been done for us. We likely will only have to change the pin connections in the code, wire it to the GPIO pins on the Raspberry Pi, and call the prewritten functions.
The next steps will be continue work on the design presentation and help assemble the equipment we ordered for the first test.
