Low Tech Communication: Morse Code + Umbrellas


Objective:
To develop a long distance communication system that is capable of sending messages at a distance of 600 yards or greater without relying on any electronic components.

Participants:
Larissa and Carolina

Materials:
2 umbrellas
2 notepads
2 pencils
2 Morse code reference sheets

Method:
Participants will use umbrellas to generate visual Morse code as a means of communication. For the purpose of the experiment Morse code will be translated as follows:

Closed Umbrella = Dot
Open Umbrella = Dash
Inverted Umbrella = Space to signify a new letter

Advantages:
Materials are easily obtainable and are low in cost
Umbrellas are durable and can withstand a variety of weather conditions

Disadvantages:
Can be a very slow means of communication
High winds may cause umbrella to turn inside out

Results:
This means of communication was somewhat effective. The main problem we encountered was a need to practice beforehand to make sure that we understood what our roles were to be.
