Capstan IV - version II
2008

A kinetic tape echo machine
made of steel, sink, cassette deck,
tape loop, water, hydrophones and plexiglass.
Drops of water generate dripping sounds in the sink. Hydrophones in the sink amplify the sounds. The drops resonate in feedback sound from the speaker below the sink. The real time sound is constantly recorded to the tape loop, which again is driven by the drops.
A ball-cock controls the waterpump. The machine is automatic.
