28th of January

Farm news
We had a few hot days and then the Australia Day log weekend cooled off a bit. I managed to get a couple of days use out of the GPUgrid crunchers. It's been fairly warm during the day, so I am crunching at night. That is except for the Raspberry Pi's.

There is a parcel waiting down at the post office I suspect it's the 5 volt fans. Looks like I might be doing some soldering on the weekend. My initial thought was to wire them up to the GPIO pins on the Pi but being worried about frying the poor thing I might just grab an old USB cable and wire it up directly to a USB connector which I can then run off a power supply, at least until I can find out how much current the fans draw. I might also want to throw a resistor or 2 in line to reduce the fan speed as 4000 RPM is probably overkill and noisy.

Asteroids project news
They are doing another server upgrade, RAID disks again I believe, so they shut down on Monday and won't be black online for at least 3 days. They also ran out of work on Sunday, probably because everybody was trying to get enough work to see them through the outage.
