Ever caught yourself doing the air-drums in the middle of a song? it is kind like inevitable behavior when you are so immersed in your beloved music. However the traditional drum set is probably on of the least portable musical instruments. Thanks to Kavin Depape, who comes up with a wonderful concept of protable drum system -Y-Drum. It consists of 9 Pads, 2 cymbals, a Bluetooth module and a companion app, either mobile or desktop. Just lay out the pads, lik them to the app, select a drum kit and your,re ready to practice. All of the hardware is stored in a box that doubles as an amplifier. To bad it is still a concept.
