For a project that we at @LAB_BINAER did lately I designed and 3D printed a optical punch card reader that’s meant to read the cards used in oldish rweaving machines. The data of these are generating sound and visuals of the big scale projection mapping.
It’s a little hard for me to share because the documentation is is not even close to the immersive character of the “real thing”…
If you happen to be in the Munich/Augsburg region drop me a line and we can meet to visit it, it will be on display untiv end of november!
