I am designing a simple device intended to count (in hours) how long a device is drawing AC power. I have already conceptualized the electronics but would look for you to analyze and enhance. The sensor will need to be a capacitive voltage type sensor. When AC is detected in a power cord, the device will start counting and store the number of hours in the flash mem of the processor. I have defined the entire functionality of the device. You will be required to develop the schematic and layout in EAGLE and the code for the processor (8 bit freescale part). I will do all testing and prototype building.

There will also be a couple small buttons on the device. We also need a 5 digit LCD and the whole system needs to be very low power. The 5 digits will be used to display the count of hours.
