The Wave Machine & output from the Wave Machine - Jack Tait

Jack Tait builds his own bespoke analogue drawing machines that, in his own words, ‘do not produce entirely random squiggles but respond to some portion of deterministic control’. Using the classic harmonograph as a model, he built the Linkograph, allowing periodic figures, similar to spirographs, to be generated. Another approach he has used is to mimic the workings of a computer program itself. His Wave Machine, is the mechanical version of a digital sinewave generator, but here analogue switches can be used to calibrate the machine to ‘program’ a different species of sinewave.
