3D RGB DreamLight Case Remix

prusaprinters

<p>I modified the case top and bottom to accommodate adding an electret microphone amplifier and a female barrel jack for power to the original design. All hardware is inside the case (Arduino Nano, a capacitor, a resistor, the microphone, and wiring. Used hot glue to hold everything together and M3-0.5 x 6mm cap screws to secure the base.</p> <p>I also used a quick disconnect plug for power to the Nano so I can program it from USB if I need to while keeping the LED matrix powered.</p> <p>I am including the code I wrote to control the LEDs. I wrote in about a half dozen variations for how the matrix will light up. My code isn't commented very well but there isn't much there so shouldn't be difficult to figure out. Also has some code in it from Adafruit to measure sound levels.</p> <p> <figure class="media"> <oembed url="https://youtu.be/5rBIQpBkwkU"></oembed> </figure> </p> <p>SOURCE CODE:<br/> <a href="https://pastebin.com/E13bxYhh">https://pastebin.com/E13bxYhh</a><br/> Audio to A1 and LED data to D3</p> <p>PARTS:</p> <ol> <li>Electret Microphone Amplifier - MAX4466 with Adjustable Gain<br/> <a href="https://www.adafruit.com/product/1063">https://www.adafruit.com/product/1063</a></li> <li>3A 12v For DC Power Supply Jack Socket Female Panel Mount Connector 5.5mm 2.1mm Plug Adapter 2 Terminal Types 5.5*2.1<br/> <a href="https://www.aliexpress.com/item/10Pcs-3A-12v-For-DC-Power-Supply-Jack-Socket-Female-Panel-Mount-Connector-5-5mm-2/32883658107.html">https://www.aliexpress.com/item/10Pcs-3A-12v-For-DC-Power-Supply-Jack-Socket-Female-Panel-Mount-Connector-5-5mm-2/32883658107.html</a></li> <li>1000uF 25V Radial Electrolytic Capacitor 10 x 17mm 105°C<br/> <a href="https://www.banggood.com/20pcs-1000uF-25V-Radial-Electrolytic-Capacitor-10-x-17mm-105C-p-1022623.html">https://www.banggood.com/20pcs-1000uF-25V-Radial-Electrolytic-Capacitor-10-x-17mm-105C-p-1022623.html</a></li> <li>Through-Hole Resistors - 470 ohm 5% 1/4W<br/> <a href="https://www.adafruit.com/product/2781">https://www.adafruit.com/product/2781</a></li> <li>2-pin JST SM Plug + Receptacle Cable Set<br/> <a href="https://www.adafruit.com/product/2880">https://www.adafruit.com/product/2880</a></li> <li>M3-0.5 x 6mm cap screws<br/> <a href="https://www.homedepot.com/p/Everbilt-M3-0-5-x-6-mm-Zinc-Plated-Plain-Metric-Socket-Cap-Screw-3-Piece-per-Bag-803168/204808021">https://www.homedepot.com/p/Everbilt-M3-0-5-x-6-mm-Zinc-Plated-Plain-Metric-Socket-Cap-Screw-3-Piece-per-Bag-803168/204808021</a></li> <li>Arduino Nano<br/> <a href="https://www.aliexpress.com/item/Newest-1-pcs-Nano-V3-0-ATmega328P-Module-Board-Free-Mini-USB-Cable-for-Arduino-Compatible/32961269354.html">https://www.aliexpress.com/item/Newest-1-pcs-Nano-V3-0-ATmega328P-Module-Board-Free-Mini-USB-Cable-for-Arduino-Compatible/32961269354.html</a></li> <li>8x8 RGB LED matrix<br/> <a href="https://www.banggood.com/CJMCU-64-Bit-WS2812-5050-RGB-LED-Driver-Development-Board-p-981678.html">https://www.banggood.com/CJMCU-64-Bit-WS2812-5050-RGB-LED-Driver-Development-Board-p-981678.html</a><h3>Print Settings</h3> </li> </ol> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><strong>Printer:</strong></p> <p>CR-10S</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Resolution:</strong></p> <p>0.2 mm</p> <p><strong>Infill:</strong></p> <p>20%</p> <p><strong>Filament:</strong> Inland PLA+ White and Black</p> Category: Art
