content: I'd like to encourage kids worldwide to have access to EE projects, Instructables, Wikipedia and general reading facilties, i.e. for faraway villages. It uses about 17 watts.Tests have been done to teach street children biochemistry, so let's teach them EE projects, because that's the best knowledge that the human form can achieve.There's going to be challenges to achieve MTBF of a dozen or so years. I don't know how much a 64 GB SD card would last for when used as a digital library operating system on Pi Zero W.

content: What is the educational concept around that idea?It‘s like hey, let’s print a book, this will deliver education to children and takes only 0 Watts and is made of recycled trees.By the way you can’t cut tempered glass, it will crumble as it is under international tension.

content: Thanks for the information about tempered glass. The classified adverts of under-developed regions have requests like "help, we need a teacher for our village, it is very far from everything" and millions of villages worldwide lack books.I like physical books, and recent colorful books are difficult to print and transport entire schools worth, compared to an SD card. The school pod also has audio and interactivity, encyclopedia, translation, integrated dictionaries.A 17" piece of tempered glass of 10mm costs $20. Car glass can be cut and perhaps doubled, windscreens would be fine for sleepy villages where everyone knows one another.I found some info while research this project, like Cairo has 1 million street children. Sub-Saharan Africa has 33% illiteracy, especially for women.Knowledge is power, so helping regions with low literacy has advantages like promoting better governance, reducing resource pressure, homelessness, higher trade, reducing immigration, better health and so forth. Repossession of land and legal advantage from powerful governments and multinationals, also affects less literate villages.A lot of immigration and conflict that we see comes from a chaotic use of technology, giving folk very strong tools without clear instructions and technologically prepared culture, which has major environmental repercussions. I studied urban and rural development at a Euro School, and environmental science at uni, so it's that kind of thing!I'm interested in:-helping promote sustainable agriculture-reducing pollution-teaching kids and adults trades and literacy-fixing failed statesthe things that are good for kids to know about!

content: You can apply plexiglass on the tempered glass if you are going for a favela version. Even in favelas, I don't think that someone would volunteer to upset all the little children by breaking their toys and books. It would be unsafe. Tempered glass is supplied to measure by local companies and car windscreens can be resized and adapted.You can drill the glass if you wish, my video suggests that folk surround strong glass with ferro-cement, why would you drill it when it's moulded in metal wire and concrete?Concrete and silicone can be UV resistant and a lot easier than drilling.

content: Quote from: libralect on April 24, 2023, 05:38:40 amHave you ever been to Cairo or any other african islamic country?Two pictures of Cairo (1999, most likely not very different from today):I think, there is plenty to do, before installing wikipedia terminals anywhere. And a teacher of any sort is *way* more effective than a computer.

content: similar concept to "The Hole in the Wall" project, well documented and researched idea that providing information technology access to children will result in self-directed learning. see:https://www.edutopia.org/blog/self-organized-learning-sugata-mitrathe whole 'recycled tempered glass' thing is an irrelevant sideshow that has nothing to do with the main concept, it is a shame folks have latched onto that one point. i fee that the video was largely directed and produced using the likes of chat GPT. ie, plausible but not factual. this should NOT be used as an excuse to detract from the the central tenet:if you provide access to information in an engaging and interesting way, groups of children (and others) will spontaneously self-organized learning around itpublic information portals is one example, another is open university lectures.an excellent read covering this and other approaches to education in poorer communities is discussed in the book: "The Beautiful Tree" by James Tooley. see:https://en.wikipedia.org/wiki/James_Tooleyhttps://www.amazon.com/Beautiful-Tree-Personal-Educating-Themselves/dp/1939709121cheers,rob :-)

content: Thanks Ron, yes I will re-dub and change the video without the AI voice, forceful storytelling and hifi sound is challenging.Quote from: Haenk on April 24, 2023, 10:39:38 amHi Haenk, Yeah I did 7000km overland in Indonesia, it's islamic, plus my family are from Sahel. dad is a prof of oriental sciences and trains diplomats for work in Saudi Arabia for i.e Washington, lol, he studied Arabic in Cairo under an author who's allegorical books were turned into Egyptian movies for the cinema.That author was attacked aged 82 in the neck in Cairo, so my dad always walked around with a mini copy of the Koran out of concern that translating a book using symbols could attract some brotherhood mafia back in the UK.What I learnt from am Algerian family and dad that lectures Arabic is that Mormonism and David Koresh could hit big too if they were "more stoned" and .... lol... yeah Françafrique is part of Africa now, the priest beheadings and clothes in paris are not that different from CAR, North Nigeria and Sahel.Any books being displayed to children must be vetted by education dept in religious states, and local sensibilities should be very carefully acknowledged.

content: Glass aside, the limitations are the SD card, temperature, and humidity...Another problem is dry capacitors from the PSU and the LCD controller.A weird thing is that the LCD has to be sealed onto the glass under a plastic sheet with dry rice to protect from condensation on the glass and screen.If it only lasts one 1 year, and 10 kids have school for a year for $90. not a fail.I'm French so tempered glass is called DURALEX here. hahha. no one fusses about it because it was invented here in 1930.

content: Ok, the silicon has shrunk on NAND flash and multiple bits are stacked in the same place, so it's less reliable today than it was in 2010. 25% of pro microSD cards fail within 2 years, and 75% will fail before 5 years, using read-only mode.So i'm upgrading the project for 10 dollars for used 64gb SSD's, available free from companies, and cheap online, their longevity is about 10 years for a kiosk.Considering the amount of news about immigration, resource depletion, conflict, bad governance, corruption, etc, i hope enhancing free education for the areas concerned, and that concern us indirectly, would chime with you as a good use of spare EE inventory!
