I'm currently planning for an installation that needs to blow air at a hanging fabric to create some ripple effects. The software side isn't the problem here, but I would appreciate if someone could give me some advice on the hardware used to generate the air blow.
The fabric will be free hanging on wires from the ceiling and the air device needs to be hidden somewhere, so my assumption is that the air needs to pass a distance of 1-2 meters and still be strong enough to move the fabric. The fabric itself will be roughly the size of a t-shirt with similar weight and there will be multiple fabrics lined up next to each other, so the spread of the air has to be considered.
The options that I'm currently considering are:
- A hidden air compressor with plastic hoses/pipes pointed at the fabric and controlled trough solenoids
- Centrifugal (squirrel cage) fans directly controlled trough an Arduino. Main concern is if they are powerful enough over the discance
- Regular, PC style, fans, perhaps stacked. Main concern again is power over distance and spread.
What do you think? Thanks
