Introduction: Mini Music Stage（Sound Visualization Device）
Every music practitioner desires a stage, but not everyone has a stage, and not everyone likes to participate in that kind of public stage. I want to create a new experience for music lovers. Whether it is practicing musical instruments, karaoke, or playing music, the stage will change different effects according to the rhythm. Everyone can have their own music stage!

Step 1: Solder the Circuit
Carefully solder the Strip, Matrix, and Microphone Amplifier to Gemma M0 as shown in the photos.
Step 2: Code Test
Upload the code to Gemma M0, try to run it, you can change the code according to your favorite song, and check the value of the song being played on the monitor.
Step 3: Cut Acrylic
I first modeled on Rhino to determine the size and then did the laser cut to get the frame of the stage. I chose translucent acrylic because its diffuse effect is so good. Remember to reserve space for the connection line.
Step 4: Make Fiber Optic Tubes
Divide the Fiber Optic tube into sections according to the size of the stage, and add hot melt glue to one section of the tube (note: during the process, keep rotating the tube until the hot melt glue is cured)
Step 5: Drilling and Assembly
According to the matrix shape, drill holes in the corresponding position of the acrylic. Be careful and take your time, otherwise, the acrylic will break. Of course, it is better to finish the laser cutting at the beginning. Use plasticine to put up the frame first, and then fasten it with strong glue.
Step 6: Combine the Circuit With the Acrylic Frame
First, think about the direction of the Strip, and fix it with the acrylic frame with strong glue. Combine the entire frame, put the matrix under the stage, add hot melt glue to the bottom of the tubes one by one, and carefully glue them to the corresponding LED lights of the matrix.
Step 7: Done It!
Fix the last piece of acrylic with superglue, we are done!
