It does seem to be less toxic resins, but I liken working with resin printers to dipping something in an open can of paint or glue. Even if it's nontoxic, it's still annoying to deal with.

Return the printer immediately. Not kidding.

Health stuff is always safety first, but I think everyone undersells just how much of a mess and pain it is to work with resin. For a rough magnitude comparison, go to your work area and spray a can of spray paint at nothing in particular for a full minute. Also, imagine you dropped your phone into an open can of paint, and now you have to fish it out and clean it without getting paint everywhere. If your setup can't cope with the fallout of doing that, you are not ready for a resin printer.
As an aside, I have found the smell of curing resin to be one of the worst things I have ever smelled; an extremely pungent plastic-y chemical smell which is hard to describe, but at least you get a warning if you don't bother to look at the pictures of dead trees and dead fish on the bottle. I'd much much rather work with hide glue again, which has the consistency of warm snot and smells like vomit.

I have dealt with such a system. I'm not sure it was GPS based but one of the options you could get was a radio system so that additional vehicles that arrived on scene would automatically sync their lights and sirens to match the ones already there. The lights and sirens themselves are CAN modules and run off a custom CAN bus. It was pretty interesting to go through the configuration software and see the literally hundreds of preset flash patterns for different regions of the world.

This is approximately what it looked like near my area in mid July for a few days.

It just looks like fog, but it is smoke, and the sky has an unusual orange color. Smells and tastes like you are standing in the path of a campfire, but you can't move out of the way. It irritates your eyes and throat if you spend more than 20 mins out there. You can go inside, but if the building you are in is leaky, it will smell like smoke inside there too.
The actual fire was hundreds of miles away. You can try driving in any direction for hours and not be clear of the smoke. Still, compared to other areas, this is barely worth complaining about.

It was just the correct time.

I rarely see yards used in the united states outside of football and other sports. Usually, distances to travel will go as feet, then right into miles. I can't think of many people who wouldn't say "quarter mile" over "440 yards". Anything less than that is in feet. Buildings and structures are measured in square feet, our long tape measures are usually labeled "300 feet" and not "100 yard", and in land surveying, measurements are often done in (decimal) feet.
One place I do come across yards is in "a yard of dirt" (or mulch, sand, concrete, etc) where it means cubic yard.

Years ago, some guy was selling a kit for some imported mini bikes that used a cordless drill and a right angle gearbox. Something about not being able to sell the gas engines that came with them, or something:

That one used a cable to pull on the drill's original trigger, so no rewiring needed.

It is very strange that when you come across anything radio related, people seemingly come out of the woodwork to tell you not that you are necessarily, actively doing something against regulation, but that there is always potential to be breaking the law.
Take this Hackaday article from the other day:
https://hackaday.com/2026/10/15/so-you-want-to-make-your-sdr...
The subject is mostly academic, but in 18 comments no less than 3 different people are warning about doing something against the rules. It's weird. I don't know of any other subject that provokes responses about "the rules" like this. I could understand if the article title was "How to Aim Laser Pointers at Airplanes", but attach a long enough wire to an oscillator and people start to get uppity.
On the other side of things, I don't know if you've turned on a shortwave radio recently, but the only thing I hear on mine is switch-mode power supply noise.

I'd probably put the typical smart switch hardware/software stack at around 0.25 seconds. Maybe you can but I don't think I'd try to rely on anything much faster than that.
If you did, I would go in the custom firmware for the smart switch direction. A lot of them are just an ESP32 inside, and you could probably get to 0.001 seconds that way (but you are switching AC which cycles on the order of 0.02 seconds, so whatever)

Was speaking more generally there; I don't think you need to know everything but I don't recommend being clueless. For the doctor example, if you are prescribed medicine, I think you should know what it is, how much and how often you are supposed to take of it, and at least at a high level what it is supposed to do for you. I've known people who don't know any of the above, and while their health outcomes weren't necessarily bad they were more complicated than they could have been.
I'm not saying you need to be paranoid and scrutinize every decision down to the molecule, but you are the greatest person who cares about the things you care about, and you deserve to know about those things.

Finding someone who will take your money is easy. Finding that they can actually be trusted to do the work correctly, on budget and on a compatible schedule may or may not take more time than actually doing the thing itself.
Also, if you do not bother to learn at all, you have no way to verify that the work is actually done correctly. People will absolutely take advantage of your ignorance.

My home internet is on a CGNAT, so I experience a lot of the same. Ironically, sometimes a VPN will get through.
