In LTspice, is there a way to change the X-Axis variable?

In PSpice I can do a PWL simulation, then change the X-Axis variable
(in Probe) to be a voltage within the circuit, thus displaying
hysteresis.

I can\'t find a similar function in LTspice.

...Jim Thompson


Left-click on the X-axis, type the expression for your signal
on the \'quantity plotted\' line in the dialog that comes up,
click OK.

Doesn\'t work. I get Error : undefined variable. It used to work but stopped
some time ago.

I am running IV.

At a fundraising event I found a very nice wood box in the electronics
section. It has what appears to be a broken decades old multimeter at
the top, and drawers full of parts below. There are a couple of small
things like switches in there that I know I could use, and a lot of
stuff that probably works but modern versions are smaller and easier to
fit into things.

I\'m basically curious if it would be a shame if I discarded any of the
contents. I\'ve got a blog post with photos of the drawer contents here:

https://qaz.wtf/qz/blosxom/2020/03/11/white-elephant-sale

It was labeled as a 1930s \"transformer repaare kit\", and while I\'ve
never repaired (or \"repaared\") a transformer, I really can\'t see it as
being very useful for that task. Well, except the multimeter, once.

That panel meter, if it works, would fetch a pretty nice price. Neo-vintage / steampunk builders love that stuff. If nothing else, just post that on eBay.

I have to chime in. I was once in an eye unit for something different. I splashed oven cleaner in my eye - NOT FUN.

Well there was a guy in the same waiting area as me. He got hot solder in his eye. Let\'s just say that he wasn\'t having fun. Really wasn\'t having fun. Like, screaming and bright red face and eye.

soo-- I\'ll just wear eye protection

My opinion is I don\'t want to know what it feels like, ever. So I will

Right, but most people don\'t learn from lecturers like you and reading stuff about safety and people bossing-around other people around.
These people only learn from experience.

How are you managing to splatter solder that far?

Solder melts, not explodes.

Here\'s one way:

Form a small ring in one lead of a a leaded part (like like a through
hole resistor, but this works best qith glass body diodes like IN4148)
Put a blob of solder over the ring

Now, hold the other lead with one hand (or in a vise), clean the tip
of the soldering iron and use it to and wipe off the excess solder
from the ring.

If you pluck the lead (like a guitar string) it wil spring back
flinging solder

I have a 132 oz. Blitz gas can that works similarly. I remove the outer
cap and pull the springy retractable spout up until it clicks into place
while flinging droplets into my face.

The small starter got weaker and weaker when hot and finally would only work once when cold. I had to replace it after 6 months.

I never noticed it when installing but there was an 800 tech support nummer on the small starter. The guy asked questions about it being grounded, etc., that made no sense after 6 months of usage.

I took it back and sure nuff the replacement, while smaller than OEM, was larger than the starter I had bought 6 months earlier. None of the 3 sizes were geared motors so someone got overly ambitious trying to save money on copper.

Moral of the story:

_Always be suspicious of low tech stuff requiring tech support_.
