2. Measure the Earth’s magnetic field intensity Measure the voltage produced Mission Overview

3. Prove or disprove Tesla’s Free Energy Theory Discover intensity of Earth’s magnetic field Mission Overview: Purpose

4. Solenoid Magnetometer Low Current Sensor Design Overview

5. Arduino UNO and MicroSD Shield Camera, Hobo, Heater, Batteries

6. Enlargement of satellite structure and rearrangement of instrumentation Addition of 9V battery to Arduino system Feedback LED added to ensure functioning of Arduino at launch Design Overview: Post Proposal Modifications

7. Design Overview External Temp. Probe 4GB SD Card Switch Camera (internal rechargeable battery) HOBO (Internal Temp, relative humidity, internal battery) Arduino Uno 9 V Battery Switch Current Sensor Solenoid Magnetometer Micro SD Shield SS Heater 9 V Batt. 9 V Batt. Switch 9 V Batt. 1GB SD Card 9 V Battery

8. Arduino recorded only 11.5 minutes of data Camera performed flawlessly Recovered satellite in virtually undamaged condition: Nothing disconnected, solenoid slightly displaced HOBO data recovered: Satellite became too cold Results and Analysis: Flight Summary

9. Results and Analysis: Temperature Data Min: -23.44*C Min: -62.25*C Burst Arduino Stopped

10. Results and Analysis: Relative Humidity

11. Results and Analysis: Voltage Data Min: ~-120 mV Average: 0.02 mV ~11.5 min

12. Results and Analysis: Magnetometer Data Average: 50.48uT ~11.5 min

13. Results and Analysis: Pictures

14. Failure Analysis Arduino Failure-Lack of Readings Heater Failure due to bad connection-HOBO Internal Temp Readings Performed additional Cold Test We were not able to repeat the failure, but failure did not occur during Failure Cold Test

15. Failure Analysis: Failure Cold Test Min: 9.42*C Min: -19.49*C

16. Failure Analysis: Magnetometer Data Average: 52.075uT

17. Failure Analysis: Voltage Average: -.78mV

18. Only 11.5 minutes of data Magnetic field does not change much as a function of altitude Voltage produced is insignificant because it is hard to distinguish from background noise HOBO data indicates Arduino or a sensor failed due to cold temperatures Conclusions

19. Do more research on all equipment Perform more thorough testing Appendix: Lessons Learned

20. Heater: Fixed Solenoid: Fixed Payload should be kept as warm as possible before flight Turn switches on and verify LED blinking Program HOBO for Delay Start Switch Camera on and verify that pictures are being taken Appendix: Ready to Fly Again

23. Remember ladies and gentlemen, always keep the final goal in mind, even when the going gets tough. There will definitely be times when it seems like you’re not going to make it but in the end it will all work out. Don’t procrastinate, because, no matter what, things are going to go wrong last minute and you’ll be scrambling to fix them. Make sure you do LOTS of research, because knowing about all of your experiments will help immensely. All the papers and presentations may seem redundant but they help you have a better understanding of what you will need to do. In the end, this class will be one that you will never forget and just remember that failures are still okay as long as you guys tried really, really hard. Appendix: Message to Next Semester
