PhyChip Synthesiser
PhyChip Synthesiser is developed by Leslie Garcia and Paloma Lopez within the PhiChip project.
- VC/VCO, voltage-controlled oscillator is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, modulating signals applied to control input may cause frequency modulation (FM) or phase modulation (PM). (wikipedia, https://en.wikipedia.org/wiki/Voltage-controlled_oscillator). Within the PhyChip Synthesiser, the VCO is given to physarum polycephalum, whose resistance varies between 1300-1500 Ohm/cm.
- In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a "trigger" because the output retains its value until the input changes sufficiently to trigger a change (wikipedia, https://en.wikipedia.org/wiki/Schmitt_trigger).
Physarum plates
Utilised coated 35 mm petri dishes in a 3 row x 2 column arrangement. Every plate was treated with an aluminium mesh with a resistance of 0.5 Ω-cm. The mesh is separated by the plate walls. In front of each cell a 4 x 3 mm aluminium finger was placed to create the contact areas. Physarum resistance was around 1300-1500 Ω·cm. On top of each plate added a 3 mm agar 2% concentration for placing the physarum.
