When teaching Numerical Methods and Matlab I like to challenge myself and take upon doing some new practical project to show my students how to apply their newly acquired skills to do something fun. This video is from the 2020 spring semester and in it I explore service time of a wireless mouse with two batteries.
For detailed problem statement and the solution see the recording on Youtube. Though, notably, the sound quality of the recording was not good. You can also find more details on GitHub, too (check out https://github.com/akononovicius/NMI-coding-session-archive/tree/main/2020-battery-problem).
