This Thursday’s electronics night, we worked on the capacitive water level sensor. We wrapped a strip of adhesive copper foil around the water tank of the silvia.  We then tried using a method similar to the arduino capsense library to get readings from the tank.  It worked not to badly the first time out.  This now needs to be refined to use a hardware counter to get the readings, and also need to take readings 8.33 ms apart to account for the 60Hz hum that these things tend to pick up. (i.e. 180 degrees out of phase)
