I've got an AVR-ISP500-TINY programmer (for programming AVR chips using the
6 pin header rather than over USB) if you want to borrow it.
On the topic of other people doing AVR chips for wireless applications...
I'm sure you guys know about these two projects but, if not:
LOW POWER LAB
* Has an open source C++ library for driving RFM12b modules (including some
* He manufactures and sells very small things called Moteinos which are an
SMD ATMega328p with an RFM12b:
* Sells lots of low power, small wireless bits and bobs:
http://jeelabs.com/collections/all (the most relevant to OpenTRV is
probably his JeeNode or JeeNode SMD)
* Also has a C library (https://github.com/jcw/jeelib) although it is
possibly not as pretty as Low Power Lab's library
