While I have the lid off the enclosure, and while my crappy Windows 8.1 tablet's camera is working I thought I'd post a close-up of the connections to the back of the Blinkt module. Online Blinkt pinouts are confusing as they are shown as though looking down on the the Pi header, i.e. as though you were looking through the Blinkt from the front.

It doesn't show in this photo, but the Blinkt is oriented with the rounded corners to the top.

The back of the speaker gets in the way of plugging Dupont cables into the back of the Blinkt at the right end, so I used a short piece of angle header and female cables for the +5V and GND connection.

You can see that the connections under the left end of the Blinkt are a bit cramped. You might want to connect the cables before attaching the right face of the enclosure.

That's enough GIMP 2.10 and Windows 8.1 for one night.
