|A camera lifted in the air with an anchored balloon.|
|Garden, Den Bunker, CCC Camp|
- helium has lifting power of 1,115 kg per m³ so a small weatherbaloon should do the trick.
- A balloon with a diameter of 1 meter has 523 Liters of volume X 1,115 = 583 grams lift
- A balloon with a diameter of 1.2 meter has 904 Liters volume = 1008 Grams of lift
- 1,8 meter diameter is over 3 kg of lifting power
- sphere or here
- Tux in space
- a balloon that is intended for 1.2 meters but bursts at 2.4 (diameter) cost 50$
- because our balloon will be on a fixed hight we can over inflate it, (Weather balloons expand when they go higher, hence the saftymargine.)
- 2m³ helium (10Liter bottle 200 bar) 75€ = 2kg lift
- 3m³ helium (10Liter bottle 300 bar) 100€ = 3Kg lift
Small servo opperated rig the holds a camera, serevo's are for pan/tild and opperating the camera, taking pictures.
