Don\'t buy that either. And even if it was true, much more of a nuisance

And even if it was true, that would be the time to consider
it if there was a problem with the current ic car, not now.

The current ic car is doing fine and is only 16 years old
and given the previous one lasted 45 years and only
needed replacing because I was too stupid to fix the
known leaking windscreen with the car never garaged
or car ported, it is very unlikely I will be replacing the
current one any time soon unless fully self driving cars
are legally available at the same time as that battery.

New models have a range comparable to a gas car, 350 to 400 miles.
Yeah, takes 30 seconds to plug in twice a week. Still faster than
stopping at a gas station.

Rather than dwell on the negatives, educate yourself and you will find
many have been overcome or will be soon.

If I had need for two cars, one would be an EV today. Even now, it is
good for 90% of my needs.

Pity about the price of those.

> Yeah, takes 30 seconds to plug in twice a week.

Not when your car isn\'t garaged or carported
and that time is just plugging, not unplugging.

Still faster than stopping at a gas station.

Rather than dwell on the negatives,

I\'m not doing that, I am pointing out why an electric
car is no use to me and isn\'t likely to ever be.

> educate yourself

Been there, done that.

> and you will find many have been overcome

None have.

> or will be soon.

If they ever are, time to consider an electric car then,
and whether they do better in any area than an ic car
because if they don\'t, no point in having one.

> If I had need for two cars, one would be an EV today.

I wouldn\'t, because the only advantage they have
is the cost of refuelling and that isn\'t paid for by
the much higher price of the car, particularly if
you don\'t buy new, as so many don\'t.

> Even now, it is good for 90% of my needs.

It has no advantage at all for any of mine, only real downsides.

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.
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.

Ah, had not thought about the counter weight, I suggested a higher
current meter, thinking that would
counter the extra weight.

Essential to keep the scale linear.

I have such a mechanism, except it doesn\'t have the pointer or scale
fitted. In fact I have several.

They are Texas Instruments chart recorders with moving coil mechanisms
to deflect the pen across the chart. Later chart recorders use
servomotors with potentiometers for positional feedback and small
motors, but these ones just have an enormous moving coil mechanism and
no feedback.

There is an Alnico (or similar) horseshoe magnet about 5 inches in each
dimension, with curved pole pieces attached, and coil about an inch and
a half across, several inches long, in precision bearings, IIRC with a
stationary cylindrical iron piece inside the coil to increase and shape
the magnetic flux.

I have no idea what use they could be but can\'t bring myself to throw
them out. I guess they might be usable as laser galvos, though the coils
are not optimised for low moment of inertia so I think they would not be
great for that.

Unfortunately unshielded magnets weighing more than several house bricks
are not the kind of things that are easily sent in a parcel, and I live
in Australia, otherwise I would try to sell you one, or give it to you
if you asked nicely enough.

Oh they\'re beautiful, but even older and better made than what I was remembering (hence those have a lot of antique value, £92+ is a bit much!), which was metal/plastic and cream coloured, sorta like the top part of these post office scales but painted cream, with just a voltage scale across it.

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

Simple is a relative term, these were professionally made in a factory.

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

Doesn\'t look so good.

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

https://www.ebay.co.uk/itm/115332876615

I was in school in the 80s, and we had massive ones, looked like some
kind of old fashioned weighscale from a fair. Very useful for the whole
class to see the volts and amps in a circuit under demonstration.

Make one yourself then. This is uk.d-i-y the clue is in the name!

Easier to press a button on Ebay, I can\'t believe nobody makes them.

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

To quickly see a value from a distance.

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

It\'s volts and amps I want.

No a larger one so people can read it from 30 feet away.

£80 + shipping is certainly too much.

All have centered needles for a +/- indicating instrument. All scales
are NOT so.
The 2nd is a really bad \'restoration\' job with a non-fitting scale, not
even aligned with the rotation center. The 3rd and 4th are also with a
bad replaced scale, but at least centered.

I\'d say this is only worth $15 + shipping.

It just isn\'t the same. Would you buy a 6.2 litre electric car?

6.2 litres of what?

Space in the pistons added together is the usual measurement.
