Matthew Falla; Fabrication

The end of this week saw another meeting with Matthew Falla of Osmotronic, discussing the final movements to be made towards production. The schematics for the design have been drawn up for Matthew to check before they are printed, including the circuit diagrams for the entire book, the cover, and the chip for sound processing. Shown is a simple system which analyses the current drawn in pencil (containing graphite) between two live bus bars of conductive ink, producing varying sounds built on this resistance.
