“TheMIDInator is a MIDI controller based on an Arduino MEGA 2560. It uses a few potentiometers, rotary encoders, a joystick, switches and a keypad as inputs and sends MIDI commands via serial ...

An Arduino Mega controls the hand with the aid of two PCA9685 PWM drivers. The physical hand itself is made out of 3D-printed PLA and nylon, painted gold for a more striking appearance.

Some of the parts you will require include an Arduino Mega 2560, 2.4 inch TFT touch Screen LCD with inbuilt SD Card Slot, 4GB MicroSDHC, 20 Pin ZIF Socket and others.

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.

This is a project from [Mirel] who built the system around a Arduino Mega 2560 and antipodal Vivaldi antennas, a type of directional antenna.
