Where can I buy a large analogue meter?

They have a small stagehand concealed within the mechanism?

Owain

Stepper motor and a counterbalanced pointer, and some drive electronics and some software.

But they used to make them as just a normal meter, just a bigger pointer and coil.

The senior technician's prep room. It is quite an Aladdin's cave in there. I think George Porters "over the shop" lecture might include some still pictures and even a video clip of that hallowed ground.

When George Porter retired they swapped rolls for a one night VIP show where he was the faithful technician and the venerable Bill Coates did his favourite and sometimes quite dangerous showy experiments.

This included washing his hands in molten lead which requires the lead to be at *exactly* the right temperature (well above melting point).

It should be somewhere on the Royal Institution website but all the video links I tried seemed to have been hijacked to Poland :(

When the world went to meters with number readouts (digital meters) "they" saw their demand for analog needle movements crater. Over time "they" quit making analog needle movements all together.

With the exception of a few niche markets (i.e., Simpson 260) you simply are *not* going to find a manufacturer making new product that meets your desires.

Your choices are going to be: make it yourself or buy an antique (if you can find one, and if you are willing to pay what the current owner demands to part with the antique).

If it's that simple make one. This is a DIY group.

I can. Why would they?. As Martin says, just keep searching eBay.

You will still be able to find large analogue pressure gauges, these are still used in industry.

Something like this one?

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

just buy a cheap servo and put a chuffin great pointer on it!

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.

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.

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.

Still no use for me.

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.

Back in 1938 they poured molten lead over the hands of kids from the audience at the Christmas Lectures. I doubt they'd try that today.
