arduino pro mini and rfm12b= nice wireless node

Hello, i'm recently playing with wireless sensor networks. This is my first decent unit working. An arduino pro mini 328 with an rfm12b on a breakout board with a chip or whip antenna. The project info is on my blog: The library I'm using is the same as the one from the Jeenode labs which is very stable and tested. The breakout boards are fairly simple and sold them soldered or non soldered on the breakout board. I'm still testing the pcb antenna to maximize the gain. Next thing I want to add is a DC-DC boost converter so that you can run the arduino pro and the rfm on a small crc 3.0v battery. Any feedback much appreciated! ;)

I got my first trasmission working with the chip antenna. And here a small video:
