While we are on the subject..
I would like to thank Bob for posting his design for us all
to use
I have mine up and running.
I could not find video or DD motor so
I used a motor from cassette tape recorder ( it probably won't
last long running 24 hours a day though ).
The spinning arm I mounted vertical with the led's mounted
on it without the 90 Deg bend.
Bob's program works great on this setup, the three poles give
me one display per rev.
mclockt.hex with the smaller numbers work best on this setup.

The only reasons for the changes I have made are that I did
not have any other motor and vertical spinning makes it easier
to mount on a wall, I have a six year old (and friends) who
(still) have ten fingers

Thanks again Bob
