Graduation caps are silly, but not silly enough! Let's customize one!3D Print
I'm a big fan of the comic Strange Planet by Nathan Pyle, so I'm using one of his comics as the inspiration and starting point for this project.
Using Illustrator and Fusion360, I transformed one of the comics into a 3D-printable object.
I also 3D printed the text "my knowledge suffices" to add to the cap.Circuit Playground
The idea is that the alien will wave around on the graduation cap using a 180 servo. A Circuit Playground will control the servo as it's very light. The LEDs of the Circuit Playground will be animated and add a charming effect around the text on the cap.
I used this Adafruit tutorial to wire the servo to the Circuit Playground. The working code is added somewhere at the end of this tutorial underneath the header "Code".Hot Glue & Duct tape
The most important step: Hot glue and duct tape everything to the graduation cap!
Use as much as you see fit, as a good rule of thumb is: there is no such thing as too much duct tape!
I hot glued the alien to a servo hub. The servo is hot glued to the bottom of the graduation cap, I made a little hole in the cap for the servo shaft, so it comes out of the front of the cap.
An A4 sized piece of glitter felt covers the holes in the cap and attempts to hide all the wires. I also glued all the letters to this piece of felt.
The Circuit Playground is attached to the cap underneath the felt with a bit of tape.
The felt is held in place by Velcro and, you guessed it, more duct tape!
Time for the last step: Power the cap and bring it to life with a powerbank.
Wear your custom graduation cap and celebrate the fact that your knowledge suffices in style!
