This project started as I wanted to practice the piano during my vacations. I started learning electronics with the Arduino kit I bought for one of my children for christmas and went to fablabs to learn about 3D Printing and Laser cutting. One year later I came with a first prototype which was made using existing midi keyboards. Now this second version is built using OEM piano keys, a custom 3D printed keyframe and laser cutter plywood for the enclosure. MIDI over BLE is provided by an Adafruit Feather Pro Micro LE board.
