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
