Thank you from the bottom of my heart for these tutorials! I am trying to create a drone, and I had problems with performances. As I am doing everything with my raspberry pi 3b+, I got a build time that is 10 times bigger than yours.. Is there any way to work with a less powerful device with the same performances of a laptop? Thanks again for your work!
