The housing for the electronics is often the trickiest part of any electronics project — and one which is usually overlooked.

The first thing I did was built out an armature for all of the electronics. This took a few iterations, some cardboard prototyping, but eventually I nailed it.

The essential components are:

1. the batteries — these have to be easily accessible so they can be recharged.

2. the Raspberry Pi — this is buried in there, but I do want to be able to sometimes pull the SD card

3. a 12V-powered USB hub that powers a wireless keyboard, the WiFi dongle and a small USB drive where the images will be stored. The little USB drive is also something I want to have access to.

4. The GPIO and the various tethered electronics coming out the back

5. Video monitor (this will end up being attached to the face) and can be detached from the rest of components in the armature.

6. Lots of cables

I wish I had better documentation of this step, since it was critical, but hopefully you get the idea. I secure the batteries with velcro. Everything else is held in by various blocks of wood. You'll see a nice photo at the end of the Instructable.
