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 Design Overview

Experiment Testing-Current/Solenoid System Current Sensor Calibration Solenoid/Current Sensor Test Readings MilliAmps Average Sensor Readings =10 milliAmps Current Sensor Calibration Control Readings Avg. Readings w/weak magnetDifference milliAmps Produced

Experiment Testing-Magnetometer RH

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 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
