How to make servo controlled gauges.

The idea is from Chris Brace.
I made the construction with his design in mind, but I thought it would
be possible to make them even more simple,

This is what I found out, perhaps they will be modified later, but sure they will do fine at the moment

Servo is glued to carboard plate that fits inside a paper tube.

This is how it looks from side, 20 minutes after I started the work.
