Re: USB Trouble B+

from time to time some RPi are droped out...
to get a replacement of a not working RPi should be not a problem.
that should be covered by normal regular waranty.
the bad thing is, the waste of time and the stress with the give back the bad RPi to get a replacement.

I have the same keyboard (Logitech k400). with NOOBS 1.3.10, usb and network of RPi B+ should work... or do you mean, that you are able to config NOOBS with your keyboard and network, but you installed an other OS (not raspbian)... maybe that OS is still not ready for RPi B+ at the moment, because o...

Re: Backing up Pi as a compact installation file

Gzipping the dd file doesn't seem to provide much compression for me. If I start out with an 8GB dd image it only compresses to 6.7GB. Same amount of compression for larger dd images (64GB). Which is odd because most of the file system is empty. It's really just system files. it is a bad idea to ma...

because the RPi has only a 100MBit/s ehternet, isn't it possible to take a 1000MBit/s cable (4 wire-pairs) and misuse the unused pairs in the cable as 5V DC powerline, because the RPi is only able for 100MBit/s (2 wire-pairs)? but you have to take extreamly care about, to do not use that misused cab...

You can not power the Pi via the gpio. A gpio should not be used to source/sink more than about 20mA. The Pi needs about 400mA to boot. i back powering my RPI B's with 5V on the 5V-GPIO-Pins without any problems! i back powering multiple RPI's like this by using a single cheap/old silent standard 2...
