For Deconstruction 2013 Our Theme was “Deconstruct a Proposal.” Christina and I have been building all sorts of projects since we met. In fact we met when I was designing my battlebot (tetracide) next to a pool on a summer day, followed by a typical date (Dinner, Home Depot, and a movie). The two of us have been together for many years and so when I decided to propose it only seemed fitting to build something to do it 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 (48 hours) prevented the full photo and videos to be displayed. Even without the message Christina still accepted my proposal so the project was a complete success. We will be finishing up the code to make the board fully functional in the upcoming days. Additionally I will be during a much more detailed write up of the build if you ever wanted to build something similar in the future.

I want to give a special thanks to everyone at the Dallas Makerspace who helped make this proposal possible. There were 15-20 people who worked around the clock for 48 hours to help me to accomplish my vision and I really appreciate all their hard work and I hope that the journey was as gratifying for them as it was for me.

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.
