File:Electronic version of Wilson's machine III.jpg

English: Electronic version of Wilson's machine, or a "double electrophorus machine". The machine is composed of two rotating complementary variable capacitors, connected to terminals where diodes, capacitors, etc. can be connected. An electric motor turns the rotating plates, making three complete capacitance variations per turn. The structure was built using two vertical HDPE plates, interconnected by threaded rods that support the fixed plates of the variable capacitors, with the rotating plates mounted on ball bearings at the center, having two sections insulated one from the other. The rotating plates have 16.5 cm of diameter, with five sections for each capacitor. The fixed plates have six sections, with 19 cm of diameter at the supporting rods. The base was cut from an MDF floor board. For the equivalent of Wilson's machine, four high-voltage, low-leakage, diodes (the type used in microwave ovens works well) are necessary, mounted as in this schematic. The two load capacitors can be provided by the distributed capacitances of the device, or can be added through the connection terminals, as shown. By Dr. Antônio Carlos M. de Queiroz (in memoriam).
