3. MISSION OVERVIEW OBJECTIVE  To investigate high altitude power generation using the kinetic motion of the balloon and a generator based on the parabolic curve of a pendulum  Most turbulent parts of flight will produce more electric voltage and current  To capture video and images from space EXPERIMENT POTENTIAL:  Provide means for alternative source of energy and power  Information on kinetic energy during flight indirectly indicates mechanical stress, influencing future structures  Getting back memorable pictures and video

4. DESIGN OVERVIEW

5. KINETIC ENERGY GENERATOR (K.E.G)  Primary payload of Dynamo  Parabolic track emulates the path of a pendulum  Magnets swing next to copper coils to induce current  The testing process (Section 2.7) assesses the function of K.E.G. in the turbulent flight environment  Voltage data collected via LASCAR EL-USB-3 data logger each second

6. DESIGN OVERVIEW  Structure:  Foam core, hot glue, aluminum tape  LASCAR Voltage USB logger  Connected to positive and negative feeds of generator  Logs data with specified rate and start time  Data stored on the USB, retrieved through PC-USB compatible software  HOBO Data Logger  Measures internal/external temperatures, humidity  Data retrieved shall be correlated with altitude information  Activated with external switch  Image and Video  Canon A780 Camera programmed to record images and video at select time intervals

10. BUDGET

11. BIGGEST WORRIES…  Generator:  Malfunctions  Lack of energy generation due to design flaws  Magnetic components interfering with electronics  Structure:  Unable to handle the rigors of flight  Staying connected to GPS unit, from which altitude data is derived  Being over budgeted weight/cost once construction begins  Malfunctions of any other electronic components, switches, wiring, solder joints, etc…
