How to build your own W-101:
-
Mill or order PCB using gerber files located in ./pcb/gerber or send an email to niclaswesemann@gmail.com to get an assembled PCB.
-
(OPTIONAL) Order components to assemble PCB as shown in ./pcb/midi_controller_pcb_component_list.csv
-
Order all components on Mouser. Link to Shopping Cart
-
Order arcade buttons on Amazon. Link to Aracde Buttons on Amazon
-
Order a Li-Polymer battery to power the Adafruit Feather 32u4 for example this one. Note that any similar battery will work. There may be cheaper or better options.

Wait for all deliveries :D
-
(OPTIONAL) Assemble PCB using the ordered components. All components except the buttons and on/off switch are placed on the PCB.
-
Laser cut the case using ./midi_controller_case/ble_midi_controller_case.ai
-
Mount the assembled PCB to the case and add buttons by soldering wires to the designated places on the PCB.
-
Flash Feather with code ./bluetooth_midi_controller/bluetooth_midi_controller.ino using Arduino IDE.
