Time machine teaser #3

I plan to have a load of dials along the back of the machine, which will be built using servos and a bit of fakery.

Servos are easy to control and cheap as chips. Building a set of dials around them might take a while but will make it more unusual looking than a set of obviously modern moving coil meters.

I've got one vintage ammeter but they're pricey and obviously a 'set' is harder to come by.

Here I've quickly mocked up one dial so I can see how it looks. The 'hand' will most likely have a fine wire pointer on the final version and I'll make more effort with the face.
