•Measure the Earth’s magnetic field intensity•Measure the voltage produced •Determine the orientation of pictures
Mission Overview
Purpose of Mission: • Prove or disprove Tesla’s Free Energy
Theory• Discover intensity of Earth’s magnetic field• Test the viability of a magnetometer as an
attitude determination system
Mission Overview
•Low Current Sensor and Magnetometer•Arduino UNO and MicroSD Shield•Camera, Hobo, Heater, Batteries

• Sync Magnetometer readings with camera pictures
• First picture taken on the eighth reading• Picture taken every two readings after
eighth
Experiment Testing-Camera/Magnetometer
Structure Testing
Whip Test
Drop Test Staircase Test
After Drop and Staircase Test
• Heater malfunctioned during cooler test• Need to turn on heater in advance of
cooler test to maintain temperature• Another cooler test to be run today
Cooler Testing
HOBO Testing
Internal Temperature Relative Humidity
HOBO taken out of freezer
HOBO placed in freezer

HOBO placed outside spout of hot kettle
• Low current generated by solenoid during flight• Magnetic field intensity decreases as altitude
increases• Accurately predict orientation of satellite
Expected Results
• Keeping satellite at proper operating temperatures
• Arduino doesn’t run for flight duration
Biggest Worries
Level 0 Requirements# Requirement Origin
0.0Test energy generation capabilities of Earth's magnetic field
