Large wooden building, originally for drying tabaco, was transformed in a large scale instruments, like a huge 3D-cylophon, where modified piano hammers played the wood with solonoids driven by Escher and EscherFET. The hut is 40m long, 16m wide and 17m high.
So they can be easily debugged, cabled and mounted on other wooden constructions.
6 scrap pianos had been disassembled and the hammer mechanic modified to be mounted in the building by Gerhard, Inge and Mauritio.
a lot of solonoids with piano hammers have been prepared for mounting
Escher and EscherFET where mounted on wood, driven by a 60A 30V power supply and the firmware updated with MAC address and IP-number.
Each Escher board drive two EscherFET driving 32 solonods with 30V 7A peak.
8 such boards has been distributed in the 40mx20mx13m building.
Wooden planks have been selected by sound and if you look carefully you will find some of hammers on the picture.
He is in standby waiting for a electric pulse.
Now hammer hit plank producing a wooden sound.
Within a control booth the main server was mounted, with keyboard and mixing desk for recording on the side.
Pure Data was used to drive the Escher boards over the ethernet cables using UDP. With broadcast the gave feedback of their activity.
Hammers ware distributed in the building with blue regions the sides, green front and back and red the floor above. so 8 boards where needed.
