What is The MIST?
 Remote firing and display design system
  intended for use with consumer fireworks
 Emphasizes safety
 Adds a level of professionalism to amateur
  shows and simplifies show design
 Allows designers to watch the show
  they’ve created
What else is out there?




        FireOne

                  Pyromate
What else is out there?
What else is out there?
   Professional Systems
     Go beyond what a “weekend warrior” needs
     E-matches are a no-no
     Cost
   Consumer Systems
     Don’t incorporate software for timing and
      audio
     Quality issues
     Safety
System Overview
The Software (MISTie)
 Database of firework pieces
 Ability to import audio tracks
 Drag and drop pieces at desired times
 Show overview display
 Software controlled system test
 Real-time launch feedback
 Safety overrides
MISTie Organization
 Database Manager
 Display Designer
 Display Observer
Database Manager
 Written in C++
 Will be able to talk to the Oracle 10g
  Express database through embedded
  SQL code
 Supports adding, removing, and editing
  data in the database
 Will include support for adding data
  through comma delimited files (.csv) that
  can be created from a spreadsheet

Display Designer
Display Observer
Control Box
Control Box
 Uses a Flexis microcontroller
 Display information is flashed serially
 Flexis decodes it and
  transmits signals to
  Ignition Platforms
  at specified times
Ignition Platform
Ignition Platform
 Uses a low power,
  low cost Arduino
  microcontroller
 Receives launch data
  serially from the
 Uses digital I/O pins to
  connect to the igniters
Ignition System: Obstacles
 Igniting Visco fuse electronically is non-
  trivial
 Unlicensed users do not have access to
  appropriate materials (E-match, quick
  fuse, chemicals, and more)
 Power concerns
 Simultaneous ignition
Igniter Options
 E-Match (illegal)
 Model rocket (break easily)
 Nichrome (slow and unreliable)
 Tungsten (slow…no ignition)
 Home made

Ignition System
Ignition System
   Advantages
     Simple design
     More reliable
   Disadvantages
     Power issues
     Number of simultaneous ignitions limited by
     Arduino’s digital I/O pins
The MIST is Multidisciplinary
   Computer Engineering
     Electronic ignition system and software
   Software Engineering
     Software’s modular design
   Systems Engineering
     System’s design and development
   Safety Technology
     System’s design and purpose
