• Even just the plain etch-a-sketch using motion sensing is cool enough.

    I suppose this might have been done already?

  • I did NOT know the motion sensors on my phone were THIS precise, that’s surprising
  • change paint brush size -> whistle

    change color -> put finger in front if camera

    make drum sound -> tap side of phone

  • Is there a reliable way to trigger percussion?
    • tap the side of the phone, it responds to accelerometer sensor.
      • Tapped very hard, never worked once. Using android on pixel phone.
  • A digital theremin! Very fun.
    • which reminds me of building breadboard RF sensors (using fixed caps with variable for calibrating parasitic capacitance) and since these are just oscillators you can calibrate a beat frequency (heterodyne mix) in audible range that has the theremin timbre of a squarish sine wave that you can plug straight to a speaker
    • It seems to make the user dance, would fun to see video of people using it for the first time. haha
