- 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.
- Pitot-tube + I2C ADC
- 10DOF (L3G4200D ADXL345 HMC5883L BMP085) (gyro, acceleration, compass, pressure, temperature)
- DHT22 (temperature, humidity)
- Power monitor (voltages & current)
- Carambola Board + WiFi
- XBeePro 500mW
- 2S 7,4V LiPo 1-1,2Ah
- 5V & 3,3V regulated.
- 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).
