PIC-Based Battery Monitor

My friends, as usual, drove me to craziness again and led me to design, fabricate and test a smart battery monitor... The usual blinking lights and so on... This prototype is using an 18-pins PIC but for the real runs, an 8-pins PIC is more than sufficient... I happen to have the 18-pins PIC in my junk box... yeah, it's a very big junk box... :)
