Professor Bubbleton's Breathing Head in a Jar #Sensors #AdafruitLearningSystem @Adafruit

• Build a “Breathing Head in a Jar” using Circuit Playground Express and an air pump. • Create a 3‑D head image, laminate, and seal mouth for realism. • Drill and seal jar with cable gland, mount electronics inside. • Wire pump via MOSFET breakout, waterproof tube and lid, dampen noise. • Program CPX in CircuitPython to detect taps and trigger breathing sequence. • Add hair, moustache, and finishing touches to enhance illusion.
