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
A digital theremin! Very fun.
It seems to make the user dance, would fun to see video of people using it for the first time. haha
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
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.
