I need the test for knowing how many does it cost for blowing ballon with proper movement speed I want. So, I test with 3~5 PWM fan, blowing test. I think the ballon material is little heavy because it is PVC and the size of ballon is too big. I have to use 5 PWM fan for this installation.
The ballon(D=1.5m)
For specific laser cutting, I use the CAD drawing again. This is for grabbing ballon on floor with weight and stick together electronic circuit in ballon.
