electronicsBicycle wheel rotation is sensed with magnetic Hall effect sensors fixed to the
branch that measure the direction and speed of the wheel rotation using magnets
placed on the rim of the bicycle wheel. With 24 magnets distributed around the
bicycle rim, 10 revolutions of the wheel will take the MIDI channel from 0 to
full scale. A microcontroller is used to interface between the Hall effect sensors
and the Miditron MIDI controller. The electronics are routed inside the pipes
so as to be minimally visible and the protect them from damage. There are connectors
at the joints for assembly. In addition to the microphones and Hall effect sensors
on the wheels, there will be light sensors, infrared motion sensors, temperature
sensors, installed on the trunk and in the speaker housing. |
