Pete,
As always it is interesting to hear what you have put in. I might ask
you for some of your lists when I get back to proverbs - I fancy a scope
clock that includes a scrolling proverb display. The other list I meant
to mention are Blake's rhyming couplets (A robin redbreast in a cage
Puts all heaven in a rage etc) which go very well mixed in with
proverbs. Having only one lifetime and what to play with during that
lifetime is unfortunately a problem we all share.
(Back to servicing the kitchen range....)

Grahame,
Thank you for the idea. I looked at the proverb list on your site, but
in the end I used a combination of several other lists that includes
quotations. I have other kinds of list I've been putting together,
including bible verses and latin epithets, but regrettably I have only
one lifetime and many other things to do with it.
The basis of this clock was a full calendar that I wrote some years
ago. It knows how to work out all the special days, including Easter,
and has a variety of messages for all of them. Apart from what I put
in, it will store user messages in EEPROM for birthday and anniversary
reminders, etc. American calendar, though - perhaps I should do a
British calendar version and send it to my mother. She would
appreciate the bible verses. I made the prototype with some HP LED dot
matrix displays I had laying around, HDSP2503 - simple parallel
interface - but they cost nearly $50 each and the clock needs two, so
my attention turned to the VFDs.
I considered using compression, but I had 64k of flash available and
found it difficult to fill it up even uncompressed. Besides, see
comment above about number of available lifetimes.
Here's a pic of the HDSP clock. I have a bag of Noritake graphic VFDs
that I rescued from a dumpster, complete display, serial/parallel. I
haven't quite decided what to do with them. It seems sacrilegious to
waste them on text or numbers. Maybe I'll do a clock with rolling
graphic numbers like an odometer.

Pete,
I'm glad you found the ideas useful. I have a much larger proverb
list which I chose from for my proverb generator when I became
short of flash. I can let you (or anyone else) have it to play
with. It includes a lot of other sayings, almost duplicates and
the "Way of Mrs Cosmopolite" (Thief of Time, Terry Pratchett).

I also have a few hundred proverbs in French (somewhere).
Did you use any compression for the text? I just about doubled the
number of proverbs I could fit in doing so.
I have a few 20x4 Itron display but I have been seriously
distracted by scope clocks. They requires just 5V and generate
all the required VFD voltages and multiplex signals, and have a
simple parallel interface. I was going to use a SD card for text
storage as simple ascii files so they could be edited on a PC and
then the SD card transfered into the clock/proverb. With just a 1
MB card that is almost "infinite" storage.
Cheers Grahame
