This lets you trigger audio files so you can play it like a musical instrument. Each button can have different sounds so you can build your own sample kit. All of the electronics are housed in our 3D printed enclosure. The top and bottom covers snap fit so it’s easy to put together. It’s designed to be portable, compact device and it’s open source.</p> <p>In previous build we used several boards to make a similar project. For this one we can use Adafruit’s Feather and the Prop Maker Feather Wing.</p> <p>Check out the learn guide for documentation. You can follow along step by step to wire the electronics and build the assembly.</p> <p>Code on github<br/> <a href="https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/NeoTrellis_Soundbox">https://github.com/adafruit/Adafruit\_Learning\_System\_Guides/tree/master/NeoTrellis\_Soundbox</a></p> <p>The software is written in Adafruit’s Circuit Python so it easy to program the hardware. We setup the REPL to print the file names and neopixel colors. This way we can verify the button mapping or catch any errors. The Feather shows up as a USB drive so you can edit the code directly on the device. All of the files live on the drive so it’s easy to change code on any computer.</p> <p>You Can Shake the device to shuffle the audio. Pressing the button on the side will reset the arrangement. We think it’s a fun demo of what you can with the accelerometer.</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=cZw4cC1Hbns"></oembed> </figure> </p> <h3>Print instructions</h3><h3>Licence: Creative Commons - Attribution Category: Electronics Hardware</h3> <p>Hardware<br/> Screws, standoffs and nuts required in this build.</p> <p>4x M3 x 20mm brass standoffs<br/> 4x M3 x 4mm heat set inserts<br/> 4x M3 x 8mm flat head screws<br/> 4x M2.5 x 10mm button head screws<br/> 4x M2.5 hex nuts</p> <h3> Parts</h3> <p>Adafruit Feather M4 - <a href="https://www.adafruit.com/product/3857">https://www.adafruit.com/product/3857</a><br/> NeoTrellis 4x4 - <a href="https://www.adafruit.com/product/3954">https://www.adafruit.com/product/3954</a><br/> 4x4 elastomer button pad - <a href="https://www.adafruit.com/product/1611">https://www.adafruit.com/product/1611</a><br/> RGB LED button - <a href="https://www.adafruit.com/product/3350">https://www.adafruit.com/product/3350</a><br/> Mini oval speaker - <a href="https://www.adafruit.com/product/3923">https://www.adafruit.com/product/3923</a><br/> Prop-Maker FeatherWing - <a href="https://www.adafruit.com/product/3988">https://www.adafruit.com/product/3988</a><br/> Mini panel toggle switch - <a href="https://www.adafruit.com/product/3221">https://www.adafruit.com/product/3221</a><br/> Metal ball tactile button - <a href="https://www.adafruit.com/product/3347">https://www.adafruit.com/product/3347</a><br/> 1200mAh battery - <a href="https://www.adafruit.com/product/258">https://www.adafruit.com/product/258</a><br/> Flashforge Inventor II 3D Printer - <a href="https://www.adafruit.com/product/3897">https://www.adafruit.com/product/3897</a><br/> Filament for 3D Printers - <a href="https://www.adafruit.com/product/2080">https://www.adafruit.com/product/2080</a><br/> Filament for 3D Printers - <a href="https://www.adafruit.com/product/2080">https://www.adafruit.com/product/2080</a><br/> Ultimaker 2+ - <a href="https://www.adafruit.com/product/2673">https://www.adafruit.com/product/2673</a><br/> Flashforge Inventor II - <a href="https://www.adafruit.com/product/3897">https://www.adafruit.com/product/3897</a><br/> 3D Parts Library on GitHub - <a href="https://github.com/adafruit/Adafruit_CAD_Parts">https://github.com/adafruit/Adafruit\_CAD\_Parts</a></p>
