Notes Michel Waisvisz designed and built the very first Crackle circuit in the late 60ties together with Geert Hamelberg. This was simply a wooden frame with some print boards mounted rear-side up to be touched by the fingers. The circuits were ‘malformed’ oscillators that were very unstable and highly sensitive for finger connections. The Crackle circuit, as well as the powered speaker box, were battery powered to avoid hum and repeated exposure to dangerous electrical shocks. In 1973 Michel Waisvisz joined STEIM and started working on more touchable electronic instruments together with Peter Beyls, Nico Bes and Johan den Biggelaar, and by the mid-seventies they had created both the ‘Crackle Synth’ and the ‘Crackle Box’.

Michel Waisvisz was connected to STEIM. STEIM (STudio for Electro Instrumental Music) is a center for research and development of new musical instruments in the electronic performing arts, located in Amsterdam, Netherlands.
You can still buy a cracklebox at their website.
