Re: Internet Access

Both the NOOBS and Raspbian issues suggest that you don't have a working network connection. Do you have any reason to believe that the cable you are using and the router port you are connecting to are both in working order? (Can you check them with another system, like a laptop?) Does the network (...

Re: forgotten password

If it is the default password you've forgotten, they are listed here - http://www.raspberrypi.org/downloads/ If it is a password that you set for yourself then things are a little more difficult. It will be necessary to know which Operating System you have installed, and whether it was installed 'di...

Re: Send Information From SPI through Ethernet

I'm sure that's a possible solution. Or you might be able to remotely run a script via ssh and have the data transferred onto the PC that way. (ssh has more uses than simply performing a remote logon to a system.)

Instead of looking for a complete solution, why not try connecting one switch as an experiment, and then build on what you have learnt?

Re: Question on feasibility

In the absence of any other response I offer a few thoughts. What you suggest sounds 'doable'. Whether YOU can do it in the next 2-3 months given your level of experience is for you to decide. The GPS part is 'easy'. There is a well-known package called gpsd which is easily installed under Raspbian ...

Re: Network Monitoring

This sounds very similar to this recent enquiry.
Ive seen a few things about apps to do what i want but they are run manually rather than constant or polled


Why not simply run one of the apps that does what you want under the control of a shell script that loops repeatedly?

If you want to work with other other hardware with rs232 serial interfaces you will probably have bought the first type, and the signal...

Re: python-dev

Read it as "With SuperUser rights, please use apt-get to install this following list of packages."

So the first just installs the python-dev package, the second installs that and the git (distributed version control) package as well.
