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 one of the least portable musical instruments. Thanks to KĂ©vin Depape, who comes up with a wonderful concept of portable 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, link them to the app, select a drum kit and you’re ready to practice. All of the hardware is stored in a box that doubles as an amplifier. Too bad it is still a concept.[source]
