Here are some teasers for the home automation and wireless sensor network project I'm working on.

This is a prototype appliance module driver board, supporting both the CC253x Breakout boards as well as the inexpensive XBee modules. This board has footprints for using either a bistable (latching) relay or a solid-state relay. Has optional support for load-sensing (for local control or burn-out detection), zero-cross detection (for dimming), and inductive current sensing. It has headers for two input buttons and two indicator LEDs.

This is a breakout board for the TI CC2520 2.4 GHz IEEE 802.15.4 RF transceiver. If the bottom header is populated, it can be used with the CC Debugger as a 802.15.4 sniffer. My primary motivation is to make it easier to work with the CC2520 as I develop a 6LoWPAN border router. You can grab the eagle sources to this board here.

This board is a add-on board for the ybox2 which allows me to use the CC2520 breakout board mentioned above. With this I can hopefully turn a ybox2 into a relatively inexpensive 6LoWPAN border router.

I've ordered all of these boards today from BatchPCB, so I should get them back in around a month or so. In the mean time, I would probably be well-advised to try to build a solder reflow oven so that I actually have a chance of successfully soldering the breakout boards.
