Jake Nylund – Computer Engineer currently working in the IT department of a steel manufacturing company. Experience with hardware and software. Website administrator and Fall team lead.
Robert Rodriguez – Computer Engineer currently working for the University of Portland. Experience with audio signal and sound equipment. Website administrator.
Project BackgroundSound visualizer using ferromagnetic fluid
Liquid that becomes magnetized in the presence of a magnetic field
Idea for this project came from two team members’ proposals:
Work with ferrofluid Work with sound to process audio input
Idea is to break the frequencies of an audio file into low-range, mid-range, and high-range
Separate ferrofluid container made of plexiglass for each frequency range

Design Challenges/RisksFerrofluid may react differently than we expect
Experiment extensively with the fluid to adequately characterize its behavior
Obtaining a power supply that can supply the amount of power needed and designing a circuit to control that power
Have yet to determine a solution
Certain hardware components may be difficult to construct
We plan to consult the various faculty members to overcome this potential future setback
Important DecisionsTesting the ferrofluid and characterizing its
behavior Key to the success of the project Allows us to determine how to best manipulate the fluid
to achieve desired results
Only building one display to begin with If there is an issue, it will only be in 1 display instead of
all 3 Once the single display functions well in testing, the
remaining 2 will be constructed
