hi scott,
a lighting detector is a good idea and the hole project is a great idea
tnx

Yeah, it'll have serial output and will probably support Peet Bros
format (and maybe at least one other) for compatibility with PC-based
weather programs and such.
I've been pondering the 1-wire sensor thing. Solar is the main thing
this would be missing, and maybe a lightning detector. But there are a
LOT of 1-wire sensors out there, and supporting all of them in an
embedded device is a lot harder than on a PC. I've got to balance the
value of having support for some additional sensors against the burden
of coding and testing support for them, and handling technical support
for third-party devices.
