  1. Frequency Response Audio Visualizer October Program Review: 25 Oct 2013 Academic Advisor: Joseph Hoffbeck Industry Representative: John Turner – Impinj, Inc. Client: William Taylor - Student Team Couch Street Jake Nylund Kevin Ratuiste Robert Rodriguez Alex Arlint

  2. Introduction • Project Overview • Scorecard • Ferrofluid and Electromagnet Tests • Test Results • Decisions Made • Upcoming Milestones • Concerns

  3. Overview • Sound visualizer using ferromagnetic fluid • Liquid that becomes magnetized in the presence of a magnetic field • Breaks the frequencies of an audio file into low-range, mid-range, and high-range and manipulates ferrofluid

  4. Scorecard • First Draft of Functional Specifications Document: 9/20/2013 (ACCOMPLISHED) • Adviser Approved Draft of Functional Specifications Document: 9/27/2013 (ACCOMPLISHED) • Final Draft of Functional Specifications Document: 10/4/2013 (ACCOMPLISHED) • Complete Testing of Ferromagnetic Fluid & Electromagnets: 10/13/2013 (STARTED) • Details to come • Determine Filters for Signal Processing: 10/20/2013 (ACCOMPLISHED) • Implement filters digitally with microcontrollers • Determine which Microcontroller to use and test: 10/20/2013 (ACCOMPLISHED) • ArduinoDuemilanove

  5. Ferrofluid and Electromagnet Tests Goals: - Make ferrofluid - Build electromagnet - Determine current and voltage needed

  6. Test Results • Ferrofluid • Made of toner powder, vegetable oil and water • Behaved unexpectedly and inconsistently • Electromagnet • Built with 16 gauge and 22 gauge wire • 16 gauge gave best results • Inadequate performance

  7. Decisions Made • Ferrofluid: Request extra funds to purchase ferrofluid • Electromagnet: Use 16 gauge wire w/ thinner insulation

  8. Upcoming Milestones • First Draft of Design Document: 11/1/2013 • Adviser Approved Draft of Design Document: 11/8/2013 • Final Draft of Design Document and Final Budget: 11/15/2013

  9. Concerns • The electromagnet • Decisions based off of test results • Power supply • Current • Programming the Arduino

  10. Conclusion • Project Overview • Scorecard • Ferrofluid and Electromagnet Tests • Test Results • Decisions Made • Upcoming Milestones • Concerns
