I want to run the RasPi truly independent so I've decided to add wireless, so no network cable, and battery power, so no power cable. With the two USB ports I can have the WiFi dongle in and the GPS as well.
I've got an old Netgear N150 wireless USB stick sitting around doing nothing so used that. Install was pretty simple and there are many guides out there. Easier to use the GUI interface.
Now, the battery pack. If you have a look at the RasPi supported hardware list there is a section for battery power packs. After having a look at the options and checking prices with Amazon I went for TeckNet iEP392 Power Bank. They are basically portable batteries that are normally used for a emergency re-charge for mobile phones.
Dual USB Ports, so I can use one for the RasPi and one for a USB Hub if I need to in future. Also comes with all the cables and connectors you should need.
Easy to setup, charge it up, min had a 3/4 charge already so only too about an hour, then just plug it in.
Now if you have your wireless running on the RasPi you should be able to put it anywhere and SSH into it.
If your so inclined you could also install tight-vnc on the RasPi and use a VNC client on your PC to run a GUI into the RasPi.
Not sure how long the battery will last but I've read up to 7hrs. So I need to test that.
So now we have a fully functioning, remote accessible and mobile RasPi. I can now just stick it in the car when I want to. Remote access it from the house and do what I need to it.
The other option I'm thinking of it to setup the RasPi as a wireless Access Point (AP). That way when I go to the track I could connect to it using my iPhone\iPad using a SSH or VNC application to trouble shoot any problems.
Next thing to do is do a few changes to the logger programme to capture some additional data than just Lat and Lon. Speed, Altitude etc, then I'll take the RasPi for a drive and see what I get.
