2. Presentation Overview • Mission Overview • Design • Organizational Chart • Schedule • Budget • Design Concerns

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…
