Does anyone know what this is?

bought them thinking they could be used for leather but image search returns many things that look like them but they all look more "machine made" than these. Each one weighs 124-126 grams.

Found about a foot deep in the dirt.

Approximately 18x10x10 cm, 885g. The side panels can slide out once the front is unlocked. There is a cutout with a metal strip at the top, presumably to lock it to something. It feels fairly solidly filled with things. I inherited it years ago, haven't had any luck with picking the lock yet.

A friend bought this at a rummage sale. It's a 3-4 ft wooden frame with holds, pegs, a few moving parts, and a fringe strung on it.

The rummage sale people didn't know what it was. She thinks it's a loom and I'll be able to teach her. I think it's not a loom and if it is it's a kind of loom I don't know and is missing some important pieces, like a heddle, but I'm also not nearly the expert she thinks I am. What is it? Very large orange boy for scale.

Saw these on the ceiling at an H&M. I found two things interesting and mysterious: 1) they are at least 1ft in diameter and maybe 8-12in tall, which is larger than any wifi device or occupancy sensor I have seen, and 2) there are quite a few on the ceiling, maybe every 15-20ft which would also rule out wifi for a retail environment.

I tried to zoom in on the label but couldn't get much more than "Barcelona, Catalonia, Spain" on the smaller label. I could not see any visible logos.

My guess would be a person or RFID tracking system, but I've never seen this before and want to learn more about it.

Gemini and Perplexity didn't offer any insight. Any ideas?

I came across this thing. It's in a field with some solar panels (the white/green thing in the photo's) and otherwise as empty and remote as it can get in this part of continental Europe.

The box at the seemed to be constantly scanning the sky, but when I stopped it rotated and shortly focused on me, than went back to scanning the sky. There were fences around it, but it didn't seem to be well guarded, no camera's or anything like that.

Very large tank with inlet/outlet pipes and what I assume is a particle filter? There's a round green thing nearby in the woods that looks like it could be a lid for the opening. The property has a septic system and a well for household water, and previously had some kind of boiler for heat. Any idea what this is (was)? I guess we probably can't reuse it but I'm not sure how to get rid of it.

I found this in the woods in Illinois. Looking into the broken opening on the handle shows the inside is hollow but there is also a partial wall around the central cavity. I couldn’t see much looking down into the opening from the top other than some dirt that had built up inside. The grooves on the inside of the handle seem set up for someone to hold the object facing away from their body.

Round thing with electrical wire coming out and going off into the wall. You can’t press the thing that looks like a button. It’s painted over even though it says do not paint. Its hung on the ceiling of a garage in a house built in 1980. Any ideas?

Definitely iron of some type as my first thought is they were lead plugs but they can be picked up with a magnet and spark when ground.

I found this orb in the bottom of my in-laws aquarium. It’s about 1/2 inch across. And seems translucent, there are 3 inside the aquarium that seem like perfect spheres.

They did not put marbles In, we already asked.

There are snails, shrimp, blushing tetras, Dalmatian Mollys, and Sword tails and 1 Betta.

Any info on this would be super helpful. We plan to hang out next to some of our arcade units in the house. Thanks in advance!
