The other idea that I'd had, with having sensors like this attached
to the internet, was an early warning system that's cheap to deploy
everywhere and effective.<br>
<br>
I'd asked myself this question, back in march.<br>
<br>
"How THE HELL - in 1967 - do you design
something so good, that: after lasting 10 years beyond your intended
design life - can also withstand a quake 7x the size of what you
designed
it for? Followed by a tsunami? Whose hand can I shake? Who gets a
medal?
Are any of those engineers from the 60s still alive? I mean, WOW.
They
did that design, at least in part, with <i>slide rules</i>."<br>

It's really amazing what watching some jugglers equipped with
ardinos and accelerometers can do to your thinking, especially if
they are speaking in a language you don't understand, but show off
the simplicity of the gerbers and chipset 4 minutes in. Gerbers
are a language I do sort of understand.<br>

There's all kinds of artistic things the demoscene is doing with
this now incredibly cheap stuff<br>

Seismograph is a possibly practical application. + Perfect time,
perfect location and altitude lock. Don't know if 12 bits at the
sample rate is useful tho. One indirect measurement is the effect
on the network of earthquakes.<br>

breakoutboards (and others including a board that has a gyro and
compass too).<br>

The Skytraq also has I2c (I was originally trying to use it to
pull J1850 data instead of my latest solution)<br>

poor coverage (which doesn't describe here, but apparently
does describe a lot of central America).<br>
