Interesting being applied in reverse. Also could had been a change in the original intention of the rooms and nobody cared.

A properly designed classroom should observe the incoming light direction for the writing direction taking place, visual without covering the writing, nor smearing the ink. Learned that at high school and never saw it divulged. Unsure modern schools take that in account...

You are entitled to your own opinion. Yes, it is. For the majority of right handed people, and languages written from left to right, it is preferred for the hand not to shade the paper being written. Which spins the next ; For languages written from right to left; are classrooms designed with windows on the right instead ? and, is there a majority of left handed in those countries ?

Some will find this a weird question. 🤔 Do you remember if your classroom at school had windows to the exterior at your left, right or any location looking towards the blackboard ? If so, which ? To be continued.

Thank you, gentlemen. Orphan phones with no service I have are half a dozen+ Androids of several flavors all working good, have installed via router to some, "walkie talkie" ; electronics audio generation tools, and borescope applications, and tried 3 trail cameras applications that are complex to operate, some have face recognition, human recognition, car recognition... A.I. ... Like meant for geniuses, not for a dumb like me. From the little I understand, the images are determined to be in motion when something like pixel "checksum" changes over a preset amount of time when sampling images and then the image is saved. Definitively not interested in time-lapse or burst method. The solar fed external battery is exactly the implemented method. Leave that aside. If you really want the spare phones characteristics, are Cricket U680AC; Coolpad 3632A; ZTE U304AA; Tracfone Z716BL; Cricket EC1002 The script portion written above is just hebrew to me. I can use it only in high-holding-hand baby-steps guidance mode.

The software determines changes in the image to trigger capture; no need to have a motion sensor on the phone. As far as I know. Settings can be changes in the image 'every xx seconds' , or recognize human, or vehicle...

Please move if there is a proper 'software' sub-forum. Am after re-purposing a retired/orphan 'smart' phone with no service, for surveillance/wildlife/trail snapshot photo camera triggered by motion; help! If you know of any application that can work, please advise. No video, no service provider, no wifi. Just hang a retired 'smart' phone on a tree; later grab the phone hanging from the tree and look at pictures taken since last hung. Ignore supplying power to it. This is not about a smart phone to communicate with a wifi wildlife camera at a trail to download images nor remote viewing. It is a walk-to-the-tree, look at the images taken, erase the unwanted. Hang it up again. Simple basics. Cannot find such ☹️ Is it too much to ask ? Decommissioned old phones filling drawers doing nothing when they have on-board the camera, the memory for saving, the brains to do it, the connectors/links to do it... Is there a web site dedicated for re-purposing these very featured useable 'junk' ? Found many complex applications all aimed to the lazy press a wifi button to get video remotely. Plenty of surveillance camera applications too, all for video. No motion triggered photos ☹️

Hi. Many surveillance and phone and other cameras can be made to see infrared by removing their IR blocking filter in the lens. Is sensitivity to thermal included when the filter is removed; or the sensor works only to a near-IR and thermal sensing is not 'near' ? What is a thermal camera spectrum ? ~12um ? Is any common canibalizable camera sensor that can be used for 'toy grade' thermal imaging ? If you want, jump to time stamp 1:10 at --> https://www.youtube.com/watch?v=2YEvkOVCaNI

Good morning mister president of the U.S. You pretended to pacify the Ukrainian conflict by negotiating armament in exchange of resources and promoting peace. Mister Putin took Ukrania and now you want your turn to take Greenland ? Sorry, there is no Nobel conflict prize, no matter how many tantrums you throw. The king of Denmark told me that you cannot afford the purchase of Greenland. As you are an expert in real estate, perhaps would prefer renting, about one thousand kilograms of gold per month, as your dollar printing machines cannot afford to make pennies. Spreading your diarrhea to Europe will not help. Hope you have a bad day.

This episode video is about those small ones on soil surface --> https://tubitv.com/tv-shows/200021886/s01-e07-dry-lake-bed

I bought many slices of smaller as these (my favorite type) for presents along years. It is a good feeling having on your hands something that old out of this world. 😳 --> https://www.ebay.com/b/Muonionalusta/3239/bn_7023272052 --> Next will be a pallasite :

Yes, probed from color and appearance first, picked up by a magnet, analyzed in laboratories mostly for iron-nickel, and details of environment effects if desertic or moist; rust/deterioration/type/family/parent documented decently well in the videos. Interesting that most are visually discernible exposed on soil surface. From my understanding, meteorites explode to small pieces by atmosphere or impact spreading large areas on surfaces because their low masses being small, do not penetrate soils, being visually found by a trained eye, also metal detectors. Why they explode in fire I cannot tell. Presence of oxygen, have temperature, but what is the fuel ?

Saw several episodes on free "Prime" TV; each at a different location all over the globe. Do not know how many are available 'on-line' --> https://m.imdb.com/title/tt1487514/episodes --> https://pluto.tv/us/on-demand/series/6227a0d24e4cae001a317f8d/season/1 --> https://tubitv.com/series/300001256/meteorite-men

Good day. Watching an entertained TV program of people searching/picking pebble size meteorites on land surface, came to a doubt... Would those meteorites on earth surface be 'very recent' arrivals, as old arrivals would be deeply buried in substrates that now have been covered with layers of sediments ? Do all sedimentary layers form under water ? Also being low mass, did not penetrate to subsoil; and larger ones are always buried under eons of layers due to their energetic impact, showing like inclusions ? -Images borrowed from the web-

Hi all. Perhaps already posted years ago but from a foggy memory and poor search skills am revising it. A magnet M with poles (N /S) has loooong polepieces as parallel iron bars (=======) at each pole. N=========================================================================E M S=========================================================================E Is the attraction to an iron part placed across the bars near the magnet M , or halfway across the length of the bars, or across the end E showing attenuation according to distance from M ? -Trying to build a 3 metres long unwanted ferrous scrap picker/collector across a conveyor belt with a magnet at one end and two bars hovering the transported material- Next... What changes if E and E are joined ( ] ), or, if at the E end of the bars, another equal magnet is attached/implemented (S/N); would the attraction force across bars be doubled ?
