DIY RGB Mousepad

thingiverse

I built a DIY RGB mousepad using WS2812B addressable LED strips and a microcontroller. The design prints in two halves, allowing you to bond them together using LePage Ultra Gel Control Super Glue or melt the joint after aligning. Another option is brown Gorilla glue, which might work too - it's cheaper than super glue. You can use any microcontroller, including ESP 32, ESP 8266, or Arduino. I've included the ino file for running on an Arduino nano; it uses the popular FastLED.h library and runs six different states: STATE_BREATHE (blue breathing), STATE_OCEAN (ocean color cycling), STATE_RAINBOW (rainbow cycle), STATE_REACTIVE (sound reactive - requires a AGC mic for this), STATE_CYCLE (mono cycle), and STATE_WHITE (white). To build the mousepad, you'll need: * WS2812B 60 led/m Black PCB IP30 strip (available at https://www.aliexpress.com/item/32849686500.html) - note that they also sell a 144 LED/m strip for smoother color transitions; be sure to modify the code and verify your power source can handle it * Tinfoil * Mousepad (Razer Goliathus Mobile Stealth Edition) * Microcontroller (check out my microcontroller project) * 3 Pin JST SM Connector (optional)
