You might get some good results out of a pocket laser projector, like an AnyBeam - that would be in focus at any range, and would have higher resolution than similarly-sized traditional projectors.

You may have trouble getting any projector to work well on a target the size of a business card, though. For the image to be so small, the projector would have to be very close, and they aren't designed for that. The image will be too bright and bleed-y.

Can you use heat tape?

Ok. Let's not play a thousand questions. Pleas describe your idea with details like size, shape, is the image coming out onto something else and if so what and how far. or is it on the surface of the box. The we can give you some thoughts.

Same. If I see them, I replace them with new receptacles and bend the wires like a normal human being.

The amount of times I have stabbed myself with a screwdriver trying to release the wire is way too high. I just cut the wires off anymore when replacing an old switch.

That’s the standard in the US.

Check out the displays they have here: https://www.adafruit.com/category/63

So you guys use solid wires? They have not been used where I live for decades... Only very old cables are still solid, the kind wrapped in cloth

Yes.

I'll look into that, thanks.

I was considering projecting onto objects, which couldn't be done with small display...but it might be easier to use a display.

Were you thinking tablet or phone, or are there other tiny displays you know of?

Yes

They make poor connections, are difficult or impossible to release the wires, and can cause unsafe connections that could short.

This is not good advice; back-stabbed connections fail at a much higher rate. If you don't want to pigtail, the plate connector on decora switches can take two wires. You just have to straighten them and make sure the right amount is stripped.

Why?

Backstab terminals are awful. Do not recommend.

Is it a moving image?

Install temporary relief in the garage (if possible) and wait a few weeks to see how your house reacts. Then proceed accordingly.

Meter, fingers, apprentice, metal grounded box whatever is closest. If it's early AM fingers is the best for a wakeup.

Thanks for the advice. If I decide to go through with this method I would use 23/32 or 3/4 plywood to drill over the shims to level (about every foot), that is supposed to be a safe enough distance to prevent bouncing.

Worst case scenario, voltage detectors (or your fingers) don't lie. Turn on the power, check the wires, see what's energized when the switch is off.

Not worth it tbh. Get yourself a mini lcd or tft.

Domestic projectors aren't designed for fine detail work, plus the globes are horrendously priced. It's not gonna look as good as in your head and it's gonna be a huge pain in the arse day-to-day

Looking on Zillow the house built next to mine is a single story with a basement. Layouts are similar but their basement is unfinished with several beams spanning across the center. Not sure why the original builders decided to forego it with this one but is probably necessary to prevent future sag.
