I'm a percussion player and have in the past developped settings where I controlled live electronics via sensors on my instruments so that playing motions could be used to generate control data. I had used a Eowave sensor board with huge amounts of cables. On some instruments that was okay but on hand-held drums like tambourines this is just a nuisance. I plan to take up the project again but with arduino boards. So my next step will be to go wireless on the tambourine controller. On a tambourine I will have 1 FSR to read finger pressure on the head and a accelerometer/gyro unit to translate both shaking motion and orientation into control parameters. Now my original idea was to replace the cables running from the arduino (due or whatever) to the sensor and back with a wireless connection. Of course on the sensor end i would not only need a transceiver but also a voltage source for the sensor - does any such thing exist? If so what is it?
But then again it might be better to keep the microcontroller and the sensor transmit the controll values wirelessly? The problem here is mainly size. The drum is only about 23cm in diameter and 5cm deep so the arduino mini would be the largest possible board. then add the gyro/accel board and a wireless unit and I end up with no space to put my hand to hold the drum, no?
Any tipps on how to address this? My ideal in terms of size is something like the K-bow
