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 Kévin 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]
