Freedom to Freedrum via a virtual drummer Want to get in touch with your inner drummer – your hidden Michael Shrieve, or Tony Williams, maybe – but you’re worried about a racket for your neighbours, let alone the cost. Well, check out Freedrum and their smart drum sticks. Just hit the air. Thanks to Nordic Semiconductor for highlighting this system in their latest Wireless Quarter. Freedrum is actually a fellow Nordic company being based in Sweden. “Play the drums anytime, anywhere,” is their slogan. The full setup comprises four lightweight devices to detect movement: one attached to each drumsticks and one for each of the drummer’s feet. These are wirelessly connected via Bluetooth LE using a Nordic nRF5232 SoC-powered and a MIDI.
