Formula Student is a racing league that pushes the limits of the volunteer teams to extreme engineering feats. Formula Student, as the name implies, means the team is made up of student volunteers and funded by donations and sponsorships. As such, frugality is a key design principle for many subsystems. When the team can’t get sponsorships for parts it is debated whether to buy off-the-shelf components using their limited budget or to make a solution from their available resources.
