Another post about lighting up instruments in a radical marching band called Brass Your Heart. This time, I used Alphabet LED Filaments on a brass bell cover for an alto saxophone.

 

Step One:

I fist started by arranging the letters and roughly positioning them on an alto sax bell cover (I used a black Protec bell cover) just to see what they would look like.

Step Two:

I need to be able to work on both sides of the cover, so I made a ring of wire roughly the same size of the alto saxophone bell.

I'm in a radical marching band called Brass Your Heart, and I wanted to make our instruments light up when we play them. I started this project by making one for my friend who plays a marching baritone. Below is a mostly step by step process for how I made them using: sewable neopixels, conductive thread, snaps, a Gemma M0, and an electret microphone. 

 

 

Step One:

The diameter of the baritone measured 26 inches, so I used tailor's chalk to draw the outer circle you see here. Then I drew another circle, about an inch in for the lights, so that the neopixels and the conductive thread is far away from the metal of the instrument. I also make 8 markings where the neopixels would go and started to sew them into position with regular black thread.
