Something like this one?

A small one and a smartphone/tablet video fed to a decent sized screen.

You wouldn\'t be able to afford an analogue meter that large.

It wouldn\'t be hard to start with a large analog clock.

Though you could build one from scratch in the true DIY fashion.

Model 8 Avo is about as big as they ever realistically get now.

ISTR Gallencamp (sp?) did larger ones for school labs back in the 70\'s.
There is a Unilab 8\" one +/- 50 uA on eBay right now.

R/C servo with pointer, PIC with ADC, code.

This shouldn\'t be necessary, in the 80s in school we had enormous
voltmeters and ammeters for demonstrations.  Just a simple coil meter
with a long lightweight pointer.

 I think using a meter to build a micro gram scale would be more fun.

Also if you extend the pointer, to make a large meter, I would suggest a
meter that passes a milliamp
vs 50 microamps. I think that would reduce error either side of center.

Search Ebay for an RCA Senior Volt Ohmist. No foot long though, ya
dope.

Bigger than that... not likely. Your brain suffers from paralax
error.

Use a small one, camera and monitor?
Or just draw it digitally on a monitor?

Could do, but I remember a long long time ago when I was at school, the
teacher had a voltmeter with a foot long needle. They must exist
somewhere.

They may well have existed then, but given the modern alternatives
suggested by Jan that exist, I doubt there\'s a market for large meters
now.

It just isn\'t the same.

Yep, a big digital screen leaves it for dead and can do far
more, show the most appropriate display, or a chart, or all
of those at once etc etc etc. And that is why no one buys
large analog volt and amp meters anymore and that is
why you can\'t buy one anymore.

I\'m not actually stupid enough to buy any electric car.

6.2 litres of what?

Battery acid per cell?

Wait 5 years. They will be much better in many ways. New battery
material, greater range, charging times not much different that pumping
a tank of gas.

Don\'t believe that will be seen in 5 years with a viable battery life.

And the battery won\'t last anything like as long as a modern IC engine.
My previous IC car lasted 45 years fine and only needed to be
replaced because I was too stupid to fix the known windscreen leak
with the car never garaged or car ported.

Not so simple if you want accuracy. For one thing, the pointer ought to be counterweighted, not
just lightweight. For another, the glass pane that protects the pointer must be grounded,
or electrostatic charge will disrupt the reading. A d\'Arsonval movement is hard to scale up
and keep rugged; taut-band and such are improvements, but... servo is what\'s easily available for
a DIY project.

You may be right. Could be three years.
