here is the latest schematic for the prebuilt: (note: I'm using a 20mhz crystal, not 16, and the zeners are both 5.1 volts, and I'm using an atmega328 currently and not a mega8), more descriptions here, i.e. switched to npn transistor for lcd and I don't try to keep the backlight running if the power dips.
