• HYDRO-POWRE: install a large water tank at the top of the Russ Atrium and use gravity to make water go down.
  • This is the real reason we have a water level sensor.
  • Totally safe. There’s no risks at all.
  • How do we fill the water tank? Where does the water go after we’re done? This is outside our scope. Future problems for other people.
  • This gives the mechanical engineers something useful to do.
  • Alternative: RBMK NUCLEAR POWER PLANT
• Microcontroller:
  • Raspberry Pi Zero
    • Pros:
      • Full OS
      • REAL sound playback: SCREAMING GOATS
      • Affordable
    • Cons:
      • No analog pins
      • Full OS will use most of the RAM
  • Raspberry Pi Pico Salsa
    • Pros:
      • Very cheap
      • Like an Arduino Uno but not Arduino Uno
      • Probably does analog inputs
    • Cons:
      • Not a full OS
      • No real sound playback
      • Might actually run Matlab (not really)
      • Limited processing powre
      • Very limited sound playback
  • Arduino Uno
    • Pros:
      • Well supported
      • Easy to work with
      • Affordable
      • Analog Inputs
    • Cons:
      • No OS
      • Airaehbehbellax will try to run Matlab on the Arduino Uno.
        • Actually, this is a pro. I need to see this.
      • Limited processing power
      • Very limited sound generation
        • Pro: this would sound horrible
        • Con: no screaming goat sounds
  • ESP32
    • Pros:
      • Nobody knows how to use this.
      • WiFi/BT, so we can flood the atrium with 44 WiFi signals
    • Cons:
      • Nobody knows how to use this.
  • Raspberry Pi 4
    • Pros:
      • Full featured SOC
      • Several on shelf
      • Plenty of RAM, processing
      • Might actually run Matlab (for realsy)
    • Cons:
      • Expensive
      • Big
      • No Analog pins
• Sensors:
  • Ultrasonic
    • Pros:
      • Full length of stair
      • Affordable
    • Cons:
      • Requires analog input
      • Crosstalk is real. We’d need to syncronize the sensors somehow to prevent this.
  • ToF
    • Pros:
      • Digital input
      • Does not reach full length of step
        • This means people can choose to not sound cool going up the steps.
    • Cons:
      • More expensive
      • Does not reach full length of step
  • Infrared Trip
    • Pros:
      • Cheap
    • Cons:
      • Limited range
      • Requires two sensors on two sides
      • Possible interference from irritable sunlight
  • Trip Wire
    • Pros:
      • Fewer Engineering Students
        • Less competition for future jobs.
        • Less people in the world.
      • Easy to implement!
      • People make sounds when they trip.
        • COLA vocal students are better for this. This was Airaehbehbellax’s idea.
        • Or Business Students. This was Andrew’s idea.
    • Cons:
      • Fewer Engineering Students
        • Someone has to give money to the university.
