What we used, and how much it cost*.
*This table includes estimated prices of the parts we borrowed from the stockrooms, such as the stepper motors. In terms of components that we purchased, we exceeded Olin's $250 budget by $86 ($21.50 per student), which is what we paid out-of-pocket for the project.
