Hmmm....  I'm thinking I may still do it for the long-term solution still=
 and=20
get the EEPROM etc with my next Digikey order.

Last night, I modified (butchered?) my code yesterday and have a hard-cod=
ed=20
working controller (so far), but it's really bastardized .... it really o=
nly=20
has 3 hard-coded event triggers in a *single* day, and I've added a div-b=
y-2=20
counter delay so 24 hours on my clock covers 48 real-time hours.  Serious=
=20
hack I know, but I got this working in less than 1 hour.  Just need to=20
convert the real-time trigger times to my clock-time. :-)

Well I got the spec from Rain-Bird (the valve mfgr) ... 24VAC, 190mA aver=
age=20
current and 300mA in-rush current.  No prob there.

Yep... I never liked the odd/even day thing.  Much prefer to set it up by=

specific days.

Oops ... I think that's my hosting-provider doing that.  It's based on a =

of rules that baffle me.
