Basically I would like to hook up 7 bowls/cups to my computer and measure if they are being "poured", i.e. how much they are tilted.
Hi
at 25$ a pop for an accelerometer, there might be easier ways of measuring that pour. What about a simple tilt sensor (2$)? A series of tilt sensors would give you numerous degrees of measurement (4 positions: 8$). Add a multiplexer chip to bring it in on one pin and the cost is still under $10.
If you can have liquid inside the bowl, you could also try putting wires along its inside to create a level gauge...
just my 2¢
