Introduction: How to Deconstruct a Wedding Proposal

For Deconstruction 2013 Our Chosen Theme was "Deconstruct a Proposal." Greg Needel and his girlfriend have been building all sorts of projects since they met. In fact they met while Greg was designing a robot on his computer next to a pool on a summer day, followed by a typical date (Dinner, Home Depot, and a movie). The two of them have been together for many years and so when Greg decided to propose it only seemed fitting to build something and Deconstruction provided the perfect platform for this to happen.

The build itself, a Large multi-display POV was a method to allow the same output as a jumbotron display without all of the complexity or cost. The display has a resolution of ~120*270 while only using 360 LEDs (vs the 32400 normally required). The goal was to build this display to display the message "will you marry me," but the time limitations prevented the full photo and videos to be displayed. Even without the message Christina still accepted Greg's proposal so the project was a complete success.

Technical Information
*3 spinners wit 120 LEDs each
*linked together mechanically with a 3/4 HP DC motor
*120 LEDs per spinner each individually addressable using the WS2812 IC on custom designed and fabricated boards.
*Each spinner features a Teensy 3.0 micro controller, a wireless module, and a sensor to detect the home location.
*Software written in Ardunio Sketch, using the FastSPI libraries (will be changed to the OctoWS2811 LED Library in the future)
*Power delivered to the boards through custom designed slip rings.
