Re: Pi unable to boot

try the last wheezy version. You might discover the problem has something to do with the firmware version.
Rev B boards require a somehow recent firmware.

i've tried with a brand new SD card with the Adafruit Occidentalis v0.2 image.
And yes, what i'm trying to do is replacing a 256 MB Raspberry.

Thanks in advance,

Pedro

Re: Weather Station

You can perhaps use an arduino to get the data from the sensors and sending it to the rpi.
I've done something like that, using the arduino in ethernet client mode and sending the data to the http/mysql server on th rpi.
i can publish my code if you'd like.

Re: Packages from debian you want to see in raspbian reposit

vgrabbj seems to be a rather old version, it still shows the error:
"Could not open configfile /usr/etc/vgrabbj.conf, ignoring"
this seems to have been corrected in more recent versions.
