  3. 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.

  4. 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 http://www.youtube.com/watch?v=6hLeKBNHBk4.

  5. System Block Diagram

  6. 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

  7. 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
