Re: Has anyone used...

[Phillip Harris <phil@xxxxxxxxxxx>]

The first project that I was hoping to do (originally using HomeVision but
mine has subsequently "died") was to use it to control the lights
and heater in my GFs vivarium so a real time clock is kinda central to that
... there are plug-in RTC modules available for the Arduino boards and both
X10 "drivers" and plug-in mains rated relay modules too so it
would still be possible but just more work than I was expecting... :-D
