Black Thunder

Minifusée expérimentale

Size:

  • Weight: 1,2 kg
  • Dia. Ø: 45mm
  • Length: 450-500mm

The rocket will be printed with a 3D-Printer. The only-non printed parts are the electronics and the core support for the engine. Maybe the parachute will be printed with flexible PLA.

Sensors:

  • GPS
  • Pitot-tube + I2C ADC
  • 10DOF (L3G4200D ADXL345 HMC5883L BMP085) (gyro, acceleration, compass, pressure, temperature)
  • DHT22 (temperature, humidity)
  • Power monitor (voltages & current)

Telemetry:

  • Carambola Board + WiFi
  • XBeePro 500mW
Power:
  • 2S 7,4V LiPo 1-1,2Ah
  • 5V & 3,3V regulated.

Parachute:

  • Servo motor
  • Arduino mini pro

The carambola board polls all the values from the I2C sensors and sends the out trough the XBeePro module. There is a debug & maintenance mode where the WiFi is on and all the Settings can be controlled trough a web Interface.

The Arduino mini pro starts a countdown as soon as the rocket is launched (an external contact is broken). It can be set via the carambola board (i2c, the value is stored in the EEPROM).
