"Inside the Box: Teaching Engineering Design through Theatrical Special Effects"

P. Paxton Marshall, Benjamin W. Kidd Charles L. Brown Department of Electrical

and Computer EngineeringUniversity of Virginia

Goals of ENGR 162

Enthusiasm for engineering Leadership and team skills, Design skills: creativity and

discipline, Resourcefulness, Critical thinking: problem

definition and solution, Social consciousness of the

impact of engineering Hands-on skills

Inside The Box Participating Classes

ENGR 162-12 – Introduction to Engineering Instructor: Paxton MarshallTA: Benjamin Kidd

DRAM 351 – Directing and Stage Management Instructor: Betsy Tucker

DRAM 372 – Playwriting II Instructor: Doug Grissom

The Project:

Playwriting students will choose three (3) effects

Directors will choose two (2) effectsEngineer teams will design and build five

(5) special effects5 minute setup and strike time10 minute performanceEffects must be controlled from a

minimum distance of 20 feet

The Five Effects

1. Balloon poppingThis effect is purposely left open-ended. The balloon popping may

be an effect unto itself, or a means of accomplishing another purpose.

2. Falling objectsObjects must fall for a duration of not-less-than five (5) seconds.

Falling items are subject to approval for safety purposes.Examples of objects that might fall:

a. Feathersb. Paperc. Leavesd. Ping-Pong ballse. Rice

The Five Effects (Continued)

3. Light moving across an actors faceThis effect is also purposely vague. A light, however, must be seen to be moving across an actors face, either side to side, up or down, or some combination thereof.

4. A flying effectAn object or objects must fly though all or part of the acting space. Movement must be predominately horizontal, in contrast to effect number 2, which is predominately vertical. Flying objects are subject to approval for safety purposes.

5. A weather effectCreate one of the following weather conditions. Weather conditions not listed shall be acceptable upon approval. Rain, Snowfall, Fog, Thunder Storm

Structuring the Teams Nine teams Four to five engineering students (40

students total), playwright, director and stage manager.

Engineering teams formed using a self-evaluation of leadership, technical, and theater experiences, which the students completed during the first week of classes. An attempt was made to create teams with strengths in all three areas.

The “Grid”

Structural support of effects Safe and convenient

electrical hookups Confines theatrical action to

manageable area Portability and fast setup

Provides “TheatricalRigging” for engineers:

Grid Components

ElectricalConnections(120 VAC &12 VDC)

1” ConduitClamps(Back-to-back)

1” EMTConduit

Standard PASpeaker Stand

The “Acting Space”

5’ Margin around front and sides of Grid

Effects shall originate from within this space

Control shall be from 20’ from front of grid

Structured Design Methodology problem definition establishing objectives and

user-requirements identifying constraints establishing design functions

and specifications generating design alternatives preliminary design and test final design, documentation design presentation

Course Text:Engineering Design:

A Project Based Introductionby Dym and Little

Class discussion Adjusting to college, the engineering profession

and disciplines, team dynamics and

communication, case studies in engineering

ethics, time-value of money, safety and environmental

considerations in design, customer relations.

Some Required Assignments

Proof of Concept Demonstrations“Interviews” of both assigned

playwright and (later on) director and subsequent documentation of the interview

Design Options ReportFinal ReportFinal Presentation

Group 4 Final Report Cover (Right)

Proof of Concept Demonstrations

Preventing last-minute projects Allowed Professor and TA to keep track of

individual group’s progress Provided opportunities of idea sharing (or

steeling) and peer review

Financial

$1k each from E-school, A&S, Provost$100 allotted for design and build

materials per group$50 of personal funds were allowed in

addition to the provided $100Teams were required to keep detailed

records of their expenditures

Popping a Balloon

Group 4 Title: “Mario and Lugi

on Sabatical” Context: Balloon pops

as a sound effect when the game ends

Basic Operation: Solenoid pulls pin releasing screw which falls and pops balloon

Falling Objects

Group 8 Title: “We are Both Hypnotized” Context: Leaves fall vertically, one at a time. Basic Operation: Motor winds up a string threaded

alternately through eyehooks and leaves

The Flying Effect Group 1 Title: “Sugar Rain” Context: Cupid’s Arrow

flies across the stage and hits a love smitten actor squarely in the chest.

Basic Operation: Arrow slides down a guide wire after being released by a motor with a movable stop.

Panning a Light Across an Actors Face

Group 2 Title: “Maybe Prague” Context: In a

melodramatic moment, a fortune teller cast in an eerie, swirling light.

Basic Operation: A MR-16 lamp projects through a cardboard pattern wheel rotated by a small motor.

The Weather Effect

Group 3 Title: “All of Me” Context: Snow is seen falling outside of a door on the

set Basic Operation: A cardboard mailing tube punctured

throughout the tube is loaded with “snow” (ground up Styrofoam) and rotated using a small AC motor.

Control Systems Group 5 Needed to Control:

(2) AC Motors (2) 12VDC Motors (2) 12V Solenoids (1) “Hot-Wire”

resistance wire for puncturing a balloon

(1) 60W Lamp (Dimmed for intensity control)

Evaluation

56% of students reported working 7 or more hours/week outside of class (vs. 7% in all first year courses)

78% strongly agree or agreed “I learned a great deal in this course.”
