This board is now available for sale in my store
Here is a little project that I worked on last weekend: A small home-made PCB to permanently fit the RFM12b-to-Serial on my Raspberry Pi. Although I am aware of at least couple on-going efforts to have native SPI support for the RFM12b, these are relatively complex and require kernel modifications. My solution may not be optimal, but is working just fine. So I layed out a single sided PCB with just a RFM12b+Attiny84+ a LED in Ealgle and 30 minutes later was already working on etching it. Here is the result, it has been working for a week now:

What exactly is the purpose of this setup? Receive transmissions from other tinysensors on the RP? It looks great, but I’m still not really sure what to do with it?
I have emoncms3 running on the raspberry, so it collects various data from all the wireless sensors I have around the house and vusualizes it. Google for “emoncms3” and also see this post http://harizanov.com/2012/06/capture-decode-and-log-to-emoncms-rfm12b-packets-on-raspberry-pi/
Ok, this looks AWESOME! When is a kit going to be ready so I can buy one for my RPi? You should think about making a case as well….
Check out the store, I have a solution there
Hi, just wondering if it would be possible to run emoncms3 on the pi and connect sensors directly to the pi, i.e. 1-wire and just a simple counter switch. Many Thanks
That is most certainly possible, a quick search shows this link http://www.element14.com/community/groups/raspberry-pi/blog/2012/08/08/raspberry-pi-speaks-1-wire-with-adafruits-occidentalis-image
