Re: PiAware for Live Flight Tracking

Looking at that website, what you are setting up is a bog standard pi setup, with a USB dongle and a PiAware SDcard image. I suggest you test by setting up the pi without either the PiAware SDcard or the USB dongle. For ease of testing you probably want to connect the PI to an HDMI port on a tv and ...

Re: Change /etc/init.b via Mac OSX

Your SD card has a conventional partition table comprising two partitions. Partition 1 is a small msdos partition. You should be able to mount and read that from a Mac. This contains the initialisation code to get the chip initialised and the kernel loaded. Partition 2 is usually an ext3 partition w...

Re: IP setting on SDCard or through USB

You need to set the contents of the file /etc/network/interfaces file in the /root directory. You can mount the SD card on a Linux computer and edit the contents of that file directly without the SD card going near a Pi. Conversely you can plug an SD card reader into the USB port of a Pi and use the...

Re: Virtual-GPIO for Raspberry Pi

Interesting idea.

Would it be possible to map that serial connection over the USB rather than the expansion header pins, to leave the Pi header free for other things, or would that be too limiting in performance.

That way you could reasonably run four of your Arduino slaves off a B+ Pi

Clones of Arduino Nano's are available at around £5, and can connect and be powered by the USB on a Pi. That gets you access to the cheap sensor shields and connection boards available for the Nano.

When you set up a link, 10M vs 100M uses a different carrier frequency. Possibly your Pi is not generating an in spec 100Mbit clock?

Re: how to enter as root user using SSH remote?

Another option is:

That spawns a root (dash) shell and feeds it the command string including redirections.

musing on ethernet hardware

Is anyone considering a hat type hardware for the Pi with something like a 88e6155 gigabit switch chip and a cluster of rj45 ports?

Given any thought to how that could be interfaced to the Pi?

If there is a practical way to make that work, the Pi would make a cracking home router.
