By a stroke of luck and resourcefulness, we took full advantage of the makerspaces on campus and also did some diving into the recyclable parts bin in SPDL. This meant that our electronics were entirely resourced from our own lab kits or from makerspaces that incurred no costs (thank you Lab64!).
We also utilized free 3D printers, particularly those in Lab64, Max Lab, and PRL AMPS (free when <$3); acrylic scraps were scavaged from past projects. Thus, the only thing we paid for was Duron for our arcade game casing!
This project totaled to $34.
