The cover image is the prototype of most of the functions (I still didn't have the neopixels and I'd already proven the PIR sensor) lashed together on a small protoyping shield, and the next tow show the casing for the project. I had an old portable handset hub as sold by the national telco, this one must have bitten the Big One as I picked it up in hard rubbish, and the lid's been modified as I'll detail later.

The 'shield' I developed for the project is a one sided solder type prototyping board that the same size as the Uno (70mm) by 90mm which means that the Uno sits sideways at one end, this is a useful configuration as you'll see. Also, turning the shield board copper side out means the components sit between the boards which reduces the height considerably, and there's heaps of space between the boards for the few components that are needed.

Mounting the shield so that the overhang is on the digital pin side of the Arduino just allowed me to use a particular configuration feature of the casing as the USB access hole.

Anyway - more pics and instructions to follow.
