In this lab, I tested 4 different stepper motors to determine how each converts the kinetic energy of cranking their shafts into electricity. The process also involved building a rectifier circuit to deal with the alternating current they produced and measuring short circuit current and open circuit voltage with a multimeter and an oscilloscope.
On this project, I worked with Kate Hartman in investigating various ways that we can use shoes to harvest energy. We came up with two functioning prototypes that address the problem from different angles: normal walking and new modes of shoes ( i.e. Heely's ).
This exploration turned out to be less of a formal project and more of an experiment with various types of BEAM circuits. My goal was to figure out how to build a walker beam circuit, but I had to learn a lot about various integrated circuits to get there.
