Electronics Update

The electronics group successfully tested the voltage data, pressure data, and altitude data collection capabilities of the StratoLogger device. The USB powered StratoLogger was tested with the PerfectFliteDataCap program. On another topic, we are considering using the Arduino board for a payload experiment. This would occur if we can’t get the IPC-A-610 Class 3 certification requirements approved with a valid electronics company. This certification applies to all custom circuit boards being used within the rocket.  In lieu of this, we may acquire another StratoLogger device.  For next week, we will construct the electronics bay prototype. Also, we will soon be testing the StratoLogger chute deployment capabilities. Additionally, the memory capabilities of the device’s peripheral EEPROM memory will soon be tested with greater scrutiny.

 

Electronics Update

Fall semester : We selected primary safety critical circuit components (SCC)  which are an:

Arduino Uno

Inertial measurement unit(IMU)

EEPROM (memory) (512 Kb non-volatile memory)(http://www.microchip.com/wwwproducts/Devices.aspx?product=24FC515)

We have enough memory but will likely have to use it sparingly.

and secondary SCC components:

This semester:

We have received the IMU and EEPROM

Reviewed wiring rules

Future:

Assessing components next week to see if components qualify as flight-worthy.
