Cristhian Avila's project "The Eternal Return, pre-Hispanic Interactions" is a sound installation that acoustically revives the time of pre-Hispanic Peru. Ancient musical instruments such as pipes or flutes, which were discovered during archaeological excavations or borrowed from various collections around the world, were scanned and made from clay-like material using 3D printing. Sensors are used to determine various wind parameters, while Arduino is used to control pneumatic systems whose valves open or close accordingly. photo credit: @tommesic . . . #arselectronica #arselectronica22 #arselectronicafestival #project #festivalproject
