Another big storm
30 Jun 2001
Another big lightning storm came through and destroyed
various bits of equipment. This is the reason that the
weather readings stopped after 6pm today until I replaced
the 'dongle' that is used to interface the sensor network
to the computer. I also lost the mouse (it melted!) and
various bits of networking gear (hub, print server).
It was all on my UPS and surge supressors, but I guess
that not much can be done for lightning. I have a whole
house surge supressor as well. I'll put up the lightning
photographs soon -- I managed to capture some strikes on
video.
Update The print server has recovered but it looks
as though the webcam didn't make it. Still, this may be
an excuse to get a better camera!
Update I had disconnected the 1-wire network from
the dongle on Sunday July 1 before the next storm came
through. Unfortunately, one of the temperature sensors
seems to have gone shortcircuit in the second storm. It
was just wired to the end of a long peice of wire, and I
guess that the induced voltage was too large (although since
it is all twisted pair, I don't really understand it).
I think that the new network will have more voltage
supressors, but I'm nervous about the capacitative loading
that it will introduce.
