Thanks. The last two replies answer it.

Frequently I do revive lithium battery packs that refuse to charge by opening the case and measuring each cell individual voltage without need to dismantle. If any is noticeably lower or under 2.5V I apply 4V to that one for a minute and when its voltage has raised above 2.5V; it is sensed by the management circuit as 'just discharged' instead of 'defunct' and the recharging can resume. Only when the application of voltage to a cell does not raise its voltage above the 'acceptable level' then the cell gets replaced to restore a pack.

Hi. Stumbled upon and unsure of its meaning. What does the word 'constitution' here refers to ? 🤨 And; any majority has to start with one or few use events; does it mean that it is a wrong word until half +1 use such and then becomes right ?

Mister president. Why do you allow the petroleum corporations to increase the local fuel prices if the U.S. is not suffering from the orient supply ? Is it the same "because they can" and you do not give a sheet ? If U. S. is exporting its surplus, has to mean does not need to import from anywhere nor the orient in trouble. Is the latest game now buying from Venezuela; pumping the price and selling to Europe and squeezing wallets to the U.S. consumer ? When will you defend the pockets of your U.S. citizens from the inflation now worsened with these greedy practices ?

Greetings... A dilute (~10% solution) of formic acid is what I used to dislodge deposits on chromed bronze parts exposed to seawater growing a greenish something on them, with excellent results. Would ~5% vinegar perform similarly, or, suggest a commonly found magic compound ? -Image borrowed from the web-

Without asking directly if one or the other; is there a way in a non-political conversation, to detect/sense if a person is democrat or republican in the U.S. or has tendency to be ? -Or by asking what ?

I was trying to choose which one would yield the most comprehensible explanation... 🤨

Thanks. What differs on... If you cannot see the terrain but only the forest above it, airborne lidar gives you the topography contours without eyeing the soil surface. If cannot visually see the ocean floor; submerged lidar scanning will not perform ?

Hello. If anyone is interested; in english : --> https://famelack.com/ir/Z0k0qEYEWnFz7F

Hi all. What are the units; is 1 gram times 300,000 Km/s doing joules ? Is it tonnes and metres/second doing watts.hour ? Do not come up with ounces, inches and BTUs, please 🙄 The formula has been everywhere with no grasp of sensing the magnitudes. Light for one gram of mass please ?

Thank you. Well, learned something else today. Infrared based. Can lidar be conducted over/across air in visible light ? It would be nearly plain photography then ?

Greetings. Does lidar surveying works to map sea bottom ? NOT from flying above water surface, but hovering under the surface ? ( as towed side scan sonar, as long as light propagation allows on reasonable transparency )

🙄 Can A.I. detect if some image / video / creation / article is a product of A.I. ? 🤔 How to attempt finding out ?

Hello all. Seen several videos on trade shows and expositions, different types. Is it some A.I. crap ? Pick any: --> https://www.facebook.com/reel/1535387904456045 --> https://www.facebook.com/reel/1286403743445332 --> https://www.facebook.com/reel/915013351081438 --> https://www.facebook.com/reel/806229785762363 --> https://www.facebook.com/reel/3335192303295817

Mister president: From which pocket the 175 billions will be sourced to compensate the unlawful tariffs ? The citizens pockets have been already drained. Is your printing machine the candidate to pay such sum ? I demand you pay me $231,670 as compensation for devaluation of my currency and assets. You have miserably failed to reverse the inflation. --> https://www.reuters.com/world/us-tariff-revenue-risk-supreme-court-ruling-tops-175-billion-penn-wharton-2026-02-20/

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.
