1. Good Vibrations Architecture Bryce Aisaka Justin Beaver Tony Felice Skanda Mohan TA: Nik White

2. Status Update Concept - A silent, portable, comfortable, battery-operated, phone activated, vibrating pillow cover. Project Idea – Finalized Parts – Purchased and destroyed a massage chair from Bed, Bath& Beyond (for research). Other parts have been ordered and being shipped. Customer Survey – Informal surveys show mostly positive feedback

3. Architecture Our basic diagram has not changed. Other parts: Pillow covers (purchased), padding (researching), connectors (researching) Arduino Nano Double A’s Solarbotics VPM2 Vibrating Disk Motor Serial port blue- tooth module Blue-tooth enabled android phone

4. Use Cases Normal Use Case Failure Case 1 Pillow battery dies Bluetooth out of range Failure Case 2 User does not wake up

5. Risks & Mitigation RisksMitigation - Hardware too bulky for pillow cover to be comfortable Strategic placing of hardware (pun intended) like batteries and wires and testing padding - User not waking up (vibration not enough, user tosses pillow etc.) Using variable motors and cell-phone speaker backup - Hardware disconnect due to rough user interaction (no pillow fights) Testing with a variety of connectors and padding - Not water-proof (drool proof)Having warning labels. Just kidding, water proofing inner layers. - Battery power not enoughUsing rechargeable batteries or AC/DC converters - Vibrations too noisyIncluding variable motor settings
