thanks for the suggestions!!
1. Reset was based on this. http://arduino.cc/en/main/standalone "Start by connecting a 10k ohm pullup resistor to +5V from the RESET pin in order to prevent the chip from resetting itself during normal operation. The RESET pin reboots the chip when pulled down to ground. In later steps we will show you how to add a reset switch that takes advantage of this."
2. I used external pullups as i read, somewhere, internals were not as reliable/accurate and were prone to noise. If this is incorrect it would greatly simplify the circuit.
3. I was worried about the crystal, i ran out of room. IF i have more room, i could consider.
4. I'll admit i didnt really consider draw. I change batteries often and 3 months sounds perfectly acceptable to me. I used this as a guide
http://forums.trossenrobotics.com/tu...-divider-3264/ and checked the measurements with a voltmeter for accuracy.
5. The battery will be physically isolated using a spdt switch attached to the power lead and the board will be completely off when not in use.
6. I will measure this, thank you.
again appreciate all the comments. I almost went to pcb today, but realized I have a few more things to do.
