Team Introduction
 Alex Arlint – Electrical engineer with 2 summers experience at
LLNL, programming in MATLAB and working on laser systems.
Aptitude in MATLAB will be useful for potential programming of
micro-controllers.
 Kevin Ratuiste – Electrical engineer with summer experience at
Uniwest working with eddy current instruments. Soldering and VLSI
chip design knowledge. Spring team lead.
 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 Background
 Sound visualizer using ferromagnetic fluid
 Liquid that becomes magnetized in the presence of a magnetic
field
 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
 Idea for this project came from two team
members’ proposals:
 Work with ferrofluid
 Work with sound to process audio input

System Block Diagram
Design Challenges/Risks
 Ferrofluid 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 Decisions
 Testing 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
