No schematics actually exist yet.

Looks like we lock before sleeping and hold the lock until we wake up from timeout. Should be enough to just have the interrupt check the thread it has a handle on is not already awake.
If the mission control team could add a couple of bits to the schematic that would be great. We'll definitely need these but I forgot to mention them when we originally wrote down all the parts of the schematic.
Not sure about the following connections, please advise+ point out anything else
Judging by this connection to an Arduino board: http://jeelabs.org/2009/02/10/rfm12b-library-for-arduino/ (used for sending packets between modules)
It seems that only the SPI pins: SDO, SDI, nSEL and SCK are needed for communication with a microcontroller. so I've left pin 3-5 unconnected for both transmitter and ground station.
The interrupt, reset and interrupt request pins are active low, so I've used 4k7 resistors to pull them up to vcc.
