I'm planning a high-altitude weather balloon project (to around 100000 feet, or 30 km) some time down the line to take video and pictures of near space altitudes and I have some questions I need to ask before doing so:
- What does the weight of a weather balloon mean such as 150 g, 500 g, 2000 g, etc mean?
- What diameter of weather balloon do I need? I'm planning to take upto around 1-2 kg of payload consisting of cameras, Arduino, Raspberry Pi, GPS, parachute etc.
