  2. Essentially, our main goal in this project was to learn and use the engineering design process as a tool to meet the criteria and constraint for building a payload.

  3. Main contents of payload enclosure

  4. Overall Payload Features: General Features • Payload Enclosure-Made of Black Foam Board • Two BASIC Stamp Circuit Boards-For mechanical and electrical support of components • HackHD Digital Camera-For capturing images while in the air (approx.$165.00) • TMP External Temperature Sensor-For measuring heat and chill variations of the air at various altitudes (approx. $1.50) • TMP Internal Temperature Sensor-For measuring temperature variations inside of the payload enclosure (approx. $1.50) • Barometric Pressure Sensor-For measuring the maximum height that our payload will reach (approx. $10.95) • Accelerometer-For capturing data of the maximum rotation of the payload during freefall back to the ground (approx. $9.95)

  5. Overall Payload Features cont. Bonus Features • Power Resistor-For keeping all of the components warm for optimal operation within the enclosure (approx. $3.95) • .NET Gadgeteer UV Radiation Sensor-Which measures the relation between air density and the transmission of UV Radiation(approx. $10.45) • Voltage Divider-This component will tell the software to shut down the heater for the remainder of the flight to conserve energy • High Pitch Buzzer-To help locate the payload once it hits the ground(approx. $1.95) Most components can be bought from SparkFun Electronics.

  6. BASIC Stamp Circuit Boards duringPopulation and Soldering Process

  7. Questions to be answered by our sensors: • At what height can the curvature of the earth clearly be seen? • What is the maximum height that our payload will reach? • What is the maximum rotation of the payload during freefall? • What is the variance of the magnetosphere at different heights from the earth? • How does air density affect transmission of UV Radiation specifically in comparison between 32,800ft and ground level? • Will adding a loud buzzer helps us to better locate the payload?
