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

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) Arduino Duemilanove

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
