Introduction: M6 Probe Balloon Project
Probe balloon project
The goal of this mission is to record aerial images of the earth and, with the help of sensors, collect data from our beautiful planet. We are two students from the Institut Sis in Manresa Barcelona (Spain): Martí Vila and Martí Subirana.

Step 1: Objective: Stratosphere!
Step 2: Tinkercad
To print the satellite box, we used the Tinkercad program. With the 3D printer we have at the Institute, we have printed the satellite and the accessories: the doors and the supports for the sensors.
Satellite design:

Step 3: Parachute
We created a parachute system using an ALTIMETER.
We built the parachute from an old umbrella. We made the launch system with springs that push the parachute outwards. We will also put an emergency parachute over the balloon.

Weighed the probe: 857.33 grams.
Test 1: With 250 gram sergeant from 10 meters high = 5 seconds.
Test 2: With 2 sergeants weighing about 600 grams. Result from 10 meters high = 3 seconds.
Test 3: We threw a 900 gram bottle of water. It went down very fast.
The approximate speed at which the probe would fall without a series parachute of 2,757.6 km / h counting that it weighed 1 kg.
Step 4: ELECTRONICS
Components:
- Raspberry pi zero
- Pi camera module
- SD card
- Arduino one
- Leds
- Servo motor
- Temperature sensor, altimeter and barometer.
- ICQUANZX GY-NEO6MV2 NEO-6M GPS module
- Module bpm280
Step 5: BPM280
Programming:
#incloure #incloure #incloure
Adafruit_BMP280 bmp;
flotador TEMPERATURA; flotador PRECIO, P0;
configuració nul·la () {Serial.begin (9600); Serial.println ("COMENEÇANT"); if (! bmp.begin ()) {Serial.println ("BMP280 no trobat!"); mentre que (1); } P0 = bmp.readPressure () / 100; }
bucle buit () {TEMPERATURA = bmp.readTemperature (); PRECIO = bmp.readPressure () / 100;
Serial.print ("temperatura:"); Serial.print (TEMPERATURA); Serial.println ("C");
Serial.println ("preció:"); Serial.print (PRECIO); Serial.println ("hPa");
Serial.print ("Altitut Aproximada:"); Serial.print (bmp.readAltitude (P0)); Serial.println ("m");
retardar (1000);
Step 6: 3D Printing
The printer used is an i3 Prussian.
We used 1.75mm flat plastic for the 3D design of the parachute satellite.
Step 7: Programming
The plates used require programming. Here we show you:
Step 8: Arduino
We also put LEDs to make the probe more visible. We have strategically placed these LEDs so that they shine and attract attention. We have made a simple but affective arduino program that makes the 2 leds intermittent.
configuració nul·la ()
{
pinMode (11, OUTPUT); } bucle buit () {digitalWrite (11, HIGH); endarreriment (2000); digitalWrite (11, BAIX); retardar (500); digitalWrite (11, ALTA); endarreriment (2000); digitalWrite (11, BAIX); retardar (1000); }
Step 9: Extreme Climate
Thermal protection
The temperature increases progressively from -59 ° C of the tropopause to reach 0 ° C of the stratopause. We have protected our probe from this climate with thermal tape https://xclima.wordpress.com/2016/08/07/ the-climate-of-the-stratosphere /

Step 11: Process
Steps we have followed:
1. First, we looked for the materials.
2. Then we did the 3D design.
3. Next, we cut the methacrylate and glued the pieces together.
4. We programmed the sensors and the camera.
5. Then we built the parachute.
6. We also did a test with the parachute.
7. Finally, we tied the balloon.
Step 12: Probe Recovery
We have placed a GPS on the satellite to know where it is at all times.
Step 13: Heli
We filled the helium balloon to propel the satellite up. The balloon exploded as the pressure increased.

Step 16: Raspberry Pi Zero
Raspberry pi zero w:
It is a very useful single-seater computer with many possibilities. In our case, we used it as a camera programmer and as a place to store the information that the sensors collect in the form of text on a micro sd card attached to the board.
Step 17: Presopost
Our budget has been quite low.
We bought the materials for amazon.
List of materials:
- Camera module Pi 9.89
- SD card 8.99
- Arduino one 9.99
- Leds 1.0
- Servomotor € 5.99
- Temperature sensor, altimeter and barometer € 8.79
- GPS module € 9.99
- Balloon € 8.99
- Heli € 22.50
- Methacrylate € 10.50
Total price: € 97.64
Step 18: Legality
To launch the satellite, permits must be requested from the airspace. A piece of sky must be reserved to avoid accidents with airplanes or others. To do this, you must contact the airline of the country itself and must provide the coordinates, the altitude that will rise and the variable information.
Step 19: Aerial Photos
Here we leave you with some images from our satellite.
