where Werner Almsberger has added a nice footprint editor.

Lua is a good language. I don't think you'll go wrong

with C however. The entire Arduino universe is

a pretty good existence proof that C is palatable. We;ll,

they have some libraries that make things easier.

As to your approach to measure wind speed, it is a clever

idea, but the old fashioned way is pretty easy.

I've decided to design

my own PCB from scratch. I'm a electronic engineer by trade so this
shouldn't cause to many headaches but if this is too difficult I will
consider using an Arduino.

Have you considered using pcb and gschem for the electronics? There's
a supportive list and good ways to get library schematic symbols and pcb footprints
besides making your own.

if you have any pointers I would

be very great full.

great full. --> grateful.

Have you done much market research on the commercial competition? There are plenty of
weather stations proven and working, so all you can hope for is a cost reduction,
and it might be tough to beat standard prices as they've been evolving for so long.
But, if you think prices are easy to beat, that's a good reason for open hardware.

The functions of a weather station barely make a microcontroller breathe hard,
so I immediately think, "What else could you add in the microcontroller part
to make a weather station better?", and it strikes me you should use a higher level
language than C for the code, and so users can adapt their stations -- use them
as development platforms. Then you have a wider market -- scientists start
to be interested, tinkerers of course, and developers of instrumentation setups.
Otherwise your market is just other EE/CS types, (if they like C).

What I like is python-on-a-chip, running on micros like
STM32 or MC13224v. See http://www.redwirellc.com/store/node/1

The STM32 stamp board can run elua, a version of lua:

That's another high level language that some say is good for rapid development. I've not tried it yet,
but it looks like time.
