"An electronic version of a North Indian percussion isntrument with Record and playback capabilities." For our final project, we decided to create an electronic version of the Dhol, a North Indian percussion instrument. The final design takes a traditional dhol and was modified to electronically produce three different sounds, as well as be able to record a drum sequence and have it play back, for learning purposes.
The drum utilizes several peripheral amplifiers and Analog-to-Digital Converters (ADCs) plus an Atmel AtMega644 to produce the different sounds. A drum hit is recorded when one of three independent force transducers are triggered by vibration, depending on which one was triggered, the corresponding sound is played.
