The Celloboard

Time period: 2005–2006

The design of the Celloboard was intended to address two weaknesses holding back new electronic instruments from audience and performer acceptance: firstly, that many electronic
instruments lack the sense of physicality possessed by acoustic instruments, and secondly, that the coupling between the performer’s energy input into the musical instrument system and the sonic output is often weak or inapparent to a performer or an audience.

For the second version of the Celloboard, a wooden neck was carved using a spokeshave, and strain gauges were bonded to both top and bottom surfaces. These sensors formed two legs of a Wheatstone bridge with control over the bias offset, and amplified with an instrumentation amp. A video demonstrating the resulting signal can be viewed below.
