What's Your Pi Plan??

Hi ya'll. Some great and wild ideas here. I am a wheel chair user. Already I have built a Pi in to my street rig. Still prototyping but it's looking good so far. My street rig is powered by 2 car type batteries - 12v / 50amphr each - and I have plenty of spare juice to run my Pi + it's accessories.

So.... starting with 12v supplied from one my batteries I created 2 power circuits - 5v to run Pi and power an usb hub - 12v to run a 10" hdmi field monitor. Circuits are regulated and fused. The 5v circuit comprises a tiny £4 12v to 5v 3amp regulator with a female usb output to which is attached a 4 port usb hub - the Pi is not the only 5v gadget I intend to run so extra power ports are needed. The 12v circuit is routed thru a 3 way car cigarette socket hub. The monitor fits nicely on an adjustable arm attached to the armrest of my wchair.

The object of all of this, apart from the simple fun of playing with the tech, is to provide me with, among other things to be dreamt up along the way, mobile internet via the Pi as I travel about. To date I've gotten a wifi dongle to work fine but no luck configuring my mifi dongle - ANY SUGGESTIONS? I have a Huawei E173 dongle which runs ok (local signal not great) on my linux laptop.

Am also trying to figure out how to interface the Pi with my chair electronics to monitor my power consumption. A major drag for wheelies with street rigs is not knowing just how much powwer you really have left. If I make a 2 mile detour will I get home before batteries run out? I live in a very hilly town and constantly need feedback on my power consumption. My rig has a crude led level display which doesn't tell me much untill it hits critical.

And then there's a few other ideas..........
