The Miselu C.24 Music Keyboard is a completely wireless device that doubles as a magnetic iPad case when not in use. This is Miselu's latest project and it recently started to collect funds through Kickstarter.
The wireless musical keyboard has impressive features, like micro USB connectivity and a lithium-ion battery for up to six hours of use at a time. Since the device also doubles as an iPad case, it is like having a mini piano at your fingertips. Although there are tons of apps that can simulate the feeling of playing the piano, it's just not quite the same as the real thing.
This Miselu keyboard has 24 keys and one of its most impressive features is that the keyboard can be popped open to raise the black keys above the white ones.
