'Code wtd: Timer with DS1302'

Anyone want to help stop wheel inventing here.

I'm looking to put together a project to provide a timer for my hifi (so
my minidisc player will record radio programmes in a timed
manner. I haven't been able to find a readily built module for this
cheaply (wall timers would work but I want something that is boxed
neatly with my hifi and has better user interface) so thought this is
an ideal project for PIC.

Idea is 16F84 with LCD and DS1302 (battery backed-up). Multi day
multi-event event timer (similar to VCR) and switch 3 mains
appliances (tuner/amp/minidisc). Simple manual/timer operation
with LED indicator.

Anyone got any DS1302 code (in MPASM - I don't have a C
compiler) or done anything similar. No problem in me poking thru
the 1302 D/S and figuring the code out but reinventing wheels
doesn't seem to make a lot of sense. In return will make the
completed project public.

Anyone got a code repository site - I've got LCD  (3 and 7 wire), I2C
to 24LC65, Morse code etc routines that I'd be happy to share.

Thanks Brian.

Let me guess, you're British and a BBC Radio 3 or 4 listener?

I only ask because in all my travels I've never met anyone else that had
a great desire to record radio programmes. Three cheers for public
service broadcasting!

Anyway this isn't the solution you're looking for - but for anyone else
that is interested, by far the easiest (and best quality) way to record
from
the radio is on your video recorder.

A video recorder with "hi-fi" tracks will give better sound quality than
any cassette (not difficult admittedly) or Mini-Disc. In fact when I did
some tests a few years back some Panasonic video recorders measured
significantly better than correctly aligned Revox 1/4inch tape machines
running at 15 i.p.s.!

Also, you get up to 8 hours recording time and you don't need an
external timer.

At home I don't have a TV, but my hi-fi stack sports a video recorder.

This seems to puzzle some visitors.
