Here are a couple of photos, one showing the daughtercard, one showing
the finished product.

I'm working on a simple count-down timer that will time from 0.1 to 999
seconds with 0.1 second resolution. I'm using an Atmel ATmega8515,
probably not the best chip but I have a ton of 'em from another project.
My problem is, it's not behaving anything like I expect. Up to about 10

Hi John,
I haven't done anything with AVR chips in a couple of years now, but
I can only add that I've felt your pain. I built a lot of clocks using
AVR parts, in a variety of designs and with a variety of AVR chips...
and they all had strange repeatable timer issues. I do think that the
Hi John,
Difficult to say something about it, without any code and hands on.
I never liked CTC timer modes. Perhaps it is easier to have an
interrupt generated only by a prescaler. Of cource that gives you
weird time values, depending on your crystal, and may give an
interrupt at every 57uS or

Great stuff Zandr - thanks for sharing.
Can you tell us a bit about your experience of the development environment
and wifi interface?
What sort of wifi range have you achieved?

Thanks, looks like purchasing one or two will not be an imp-ulse buy.
I'm dubious as to the 1km range - maybe in the desert using battery power,
10F decap, 1bit/s and directional antennae. Certainly not at 400mA anyway.
100m is plausible and would seem to imply no corners were cut in the RF
