Raspberry Pi Model A modify to work with 3.3V input (remove 3.3V regulator & Capacitors) don't plug in USB HuB with 5V external adapter will burn Raspberry Pi & P-HAB board 1. 04 Jun 2014 Balloon launch 2. 07 Jul 2014 Balloon launch 3. 13 Jul 2014 Balloon launch 4. 20 Jul 2014 Balloon launch 5. 27 Jul 2014 Balloon launch 5V HAB Ready for sell now 23 Jun 2014 This project is used for balloons to explore the edge of space. Collecting temperature, humidity, altitude, pressure data sending back through a FM Transmitter and saving all logs into the SD card. Also it can take a photo every 30secs and then saving it into the SD card. The project use 1. ublox-7Max GPS module 2. Radiometrix NTX2B 434.xxx Mhz 10mW modules. 3. TMP102 temp sensor to monitor Raspberry Pi temperature 4. BMP085 Barometric Pressure/Temp/Altitude Sensor 5. DHT22 / AM2302 Digital Temp & Humidity Sensor or i2c HTU21D Digital Temp & Humidity Sensor 6. TRACOPOWER 3.3V (TSR-1-2433 ) DC/DC converter (DC input Min 4.75V ) up to 96% efficiency - No heat-sink required ( for longer battery life) 3.3V provide to Raspberry Pi & Rs Pi P-HAB module board 7. Raspberry Pi Camera kit ( take photos save into SD card)
3.3V ver Pi-P-HAB board plug-in 3.3V model B GPS antenna & FM antenna & USB SDR Encoder (RTL2832U-based DVB-T devices (RTL-SDR) eduhap.py -s short data stream mode send GPS location and BMP085 Temp only , but all logs save to SD card eduhab.py -p send data also take photos every 30sec eduhab.py -c prid change the data stream "twick" to "prid" |
