This is the breadboard that I used. I solder the corresponding wire to the breadboard. I then taped the breadboard the the flipper flappers.

 I changed the flipper flappers and used a table saw. I taped the servo to the flappers.

 I attached the breadboard the the trinket and then attached velcro the the flipper flapper.

 I then attach the flippers to the headphones.
