Electronic Bow
custom design and build of an electronic bow (or e-bow)
continuously vibrates a guitar string
produces a sound similar to a violin bow
Circuit Board
contains all electrical components
connections for battery and LED
pick-up and drive coils on underside
Base Housing
machined from aluminum
mounts for circuit board and acrylic cover
holes for pick-up and drive coils as well as LED
string grooves to keep e-bow centered over the drive string
How It Works
a pick-up coil detects string vibrations
an amplifier uses the energy stored in the battery to increase the amplitude of that signal
the amplified signal is sent to a drive coil, which causes the amplitude of the string's vibration to increase
this increased vibration is detected by the pick-up coil, creating a continuous positive feedback loop
