[time-nuts] Sidereal timekeeping

[iovane at inwind.it]

Neville,
at present I have not enough skill with micros to solve the problem. 
I think I will try modifying a crystal. This would not be that difficult using 
a lapping sheet or the like. And opening the can would be quite easy using hot 
air. This is the fastest way for me, and the device will continue to be powered 
by a simple AA cell, which is a non negligible advantage in my application.
All the best,
Antonio I8IOV
