It would be how the voltmeter would have been wired back then, you can damage the needle or it’s spring by pegging it for too long. Even then though, the only real issue I would forsee would just be the voltmeter spiking all the way to the right while it’s ringing, the chance of any real damage is pretty minimal. You can also check the datasheet on the meter, it should tell you what it can safely handle.

It’s looking like you are going to want to hook the volt meter up to your talk lines. I would test just probing the wires going to the handset, if I understand the schematic correctly the talk circuit is separate from the ringer. That being said, you can get a voltmeter that is tolerant of the voltage. In my experience anything under 400v is fine for most voltmeters, they use a resistor divider that have values in the megohms, the current passed across them is minimal.

As far as blinking on ringing, that one is super simple since the ringer is AC, just use an induction type detector to flash an LED on. Think along the lines of those screwdriver looking line voltage testers that light up when you put them next to a live outlet.

Edit: I should clarify what I mean when I say the ringer is on a separate circuit. There is a coil that energizes when the line goes up to ringer voltage that shunts power to the ringer and away from the talk circuit, so measuring the voltage from the handset or speaker should protect you from seeing the ringer voltage.

Oh, name and shame for that shit.

Richard Burke at Casper College does this and doesn’t even use the book. Costa over $150.

Garbage practice that should be criminal fraud.

Everyone except management.

It’s beyond fucked.

I can speak firsthand that this is the case for Kroger in Illinois. Their unions fight to cap wages below living wage levels, pick some of the most expensive insurance on the market, and work with Kroger corporate to eat away your hourly rate with sliding payscales based on incredibly arbitrary criteria (overnight premium, but it only counts for 4 hours of a graveyard shift as an example that happened to me).

They are actually worse than not having a union, because then they could make more than $23 an hour in Chicago.

Oh, did I mention the union contract specifically prohibits strikes and any form of worker retaliation?

Awful company.

Corn sugar is made up of a pretty large amount of glucose, so eating corn is like eating one of the shock tabs. Which is also a good way to confirm that it’s glucose; rice, beans, and chocolate cake all contain pretty small amounts of just glucose, the other sugars need time to break down.

You are going to be looking at some variant of oculink, you can get riser cards that convert a PCI-e or M.2 socket into an oculink port if you don’t have one available stock. Still though, if you are building it yourself why even bother? You are going to add a significant cost to the build for marginal or no benefit over buying a mini PC with an oculink port and a known compatible dock. EGPU options are not plug and play, they rarely just work and need significant tinkering and workarounds and will come with noticeable drawbacks in the best case scenario.
