Construction:

• Doumbek aluminum cast body and standard 10 inch mylar drumhead
• 10 piezo film sensors, mounted on the underside of mylar drum head
• Drumhead wiring implemented with flexible copper tape, clamp interface at rim to internal wiring
• 3-axis accelerometer tilt sensor

Observations:

• Copper tape appears to have long-term stability problems and does not recover easily from deformation
• The layout of connectors on the drum head requires small-tolerance placement of the tape; a larger spacing of leads would be better
• Piezo film requires careful amplification and filtering
