[time-nuts] Lady heather on a Raspberry pi

Hi, I have had Lady Heather running on a small pc for a number of years, controlling a 
thunderbolt- until the pc quietly died a couple of weeks ago.

As I didn't have another spare pc, but I did have a couple of spare raspberry pi's, I 
thought to have a go at putting it on a Pi. Using the instructions of the LH web site, I 
had it running quite quickly and with no real drama. Even better, the whole thing 
(including the t'bolt) now mounts on the back of a 17 inch lcd monitor, making it a very 
neat installation.

The problem came when I wanted to run a small fan for temperature control of the 
thunderbolt- no matter how I searched, I could not find out which io pins LH uses on the 
pi to control the fan. The pi doesn't have a "real" serial port, and my software skills 
are nowhere near good enough to dig through the source code to figure this out.

So I would be grateful if someone could tell me which io pins I need to use to control the 
fan so I can get a bit tighter control of the t'bolts temperature excursions.
