Bluetooth Wind Controller

thingiverse

This wind controller uses a Bluetooth Low Energy (BLE) wireless link to send MIDI data to a synth app running on an iphone, ipad, etc. The body, mouthpiece, and mounting parts are all 3D printed, and it features capacitive touch sensors for the main keys. It uses an inexpensive Force Sensitive Resistor (FSR) to detect breath pressure. There are a wide variety of compatible synthesizer software programs available from the Apple App Store, the Microsoft App Store, and elsewhere. I mainly use an iPhone with this wind controller, and my favorites synths are the Roli Seaboard 5D app, GarageBand, the Yamaha Synthbook AN2015 app, and the Korg Gadget LE Marseille app - all are available for free from the Apple App Store. Visit my website's project page for this wind controller for a complete parts list, build photos, operating software, and much more information! https://markwtech.com/synthesizer/wind-controller-ble/ Operating software (Wind_Controller_BLE_V1_0.zip) is included in the 'Thing Files' section. A video demonstration of the wind controller is on YouTube at https://www.youtube.com/watch?v=YbP_60VK9_Y The mechanical parts are all 3D printed in PLA. You'll need a printer with a fairly large bed for the three large parts: Body Top, Body Bottom, and Body Bottom Skin. I printed these individually at a 45 degree angle on the print bed. Note that these parts will not fit on a printer with a print bed smaller than about 250mm x 250mm. The following parts were printed in black PLA: - Body Bottom Skin - Bottom Switch Mount - FSR Support - IMU Support - Left Switch Mount - Mouthpiece - Neck - Plunger - Retaining Ring - Right Switch Mount 1 - Right Switch Mount 2A - Right Switch Mount 2B - Top Switch Mount 1 - Top Switch Mount 2 The following parts were printed in gold PLA: - Body Bottom - Body Top - Bottom Plug - Breath Chamber Lower - Breath Chamber Middle - Breath Chamber Upper - Insert Practice Piece All of the parts except the plunger are printed at 0.2mm layer height with 30% infill. Most of the parts can also be printed without support material - the only parts that I printed with support turned on were the Breath Chamber Lower, Breath Chamber Upper, Plunger, and Neck. For strength, the Neck is printed sideways (as oriented in the STL file).  I also used a raft for the Plunger and Neck. Since it's such a small part, the Plunger was printed at 0.1mm layer height.
