It is installed and running off of a 12v leisure battery – there is a cigarette lighter adapter with 2 USB ports running power to the Nano Router and the Pi
The Pi is mounted on a shelf – in a little cradle made from EVA foam to stop it sliding about. The camera is mounted with some velcro under the shelf which can be angled as required.
We used it for the first time yesterday as I took Luna out to a horse show and it worked beautifully. Streaming the image to the iPad worked really well. The picture was good and the battery appears to be lasting forever which is also good.
So all in all I am over the moon with it – I will look to improve it, but so far so good. I will post an update with any improvements we make 🙂
