Open Source Thermostat and more (Schematics)

I've just put up a very basic (schematics only at this time) site.
There are currently four projects:

http://www.myblueroom.com

    Cricket Communicating Thermostat (IR, iButton, RS232 or 485)

    Ladybug Super IO Controller  (RS232 & RS485, RTCC with 24hr backup,
6
relays, 3 digital & 1 digital/analog input, 1 iButton)

    Daisy Communicating Clock (six digit RS485)

and just for fun Dice

All are PIC Microcontroller based, some are configurable at build time.

Example: Cricket will work stand alone (1 relay) or mate with Ladybug
(6
relays) similar hookup to an RCS type thermostat.
Ladybug can be standalone similar to an Elk Magic 443, but with more
IO,
both RS232 & RS485 and a RTCC as standard. Can be upgraded to 32K when
using
a PIC 18F2525 instead of the standard 16F876

Also all (except the dice) can be reflashed via the serial port
(bootloader)
and the Ladybug supports ICD/ICP

I'm looking for ideas, advice etc...  I want to make open source home
automation products for anyone to afford & use.  Also any help would be

appreciated.
