When I was 17, I had idea to make the world's cheapest computer. I had a receipt printer at my house, and I thought if somebody invented re-writable receipt paper, it would be cheaper than LCD. I did not have enough resources to solve and build an exact prototype.
I invented my own 3D printer using a projector, and it was not an FDM. 99% of 3D printers were FDM in that year. I needed an SLA printer to make prototypes of my ideas, but I could not afford one. I was too poor. I built one out of metal, circuits, and custom software for a thousand dollars. My 3D printer used Ultraviolet light from a DLP projector to cure plastic resin.
UV LCD SLA 3D Printers come to market as first LCD with high transmittance for UV light. SLA LCD 3D printers before this new type of lcd panel had poor transmittance and were considered a hack.
I finally thought of a receipt printer computer after not having had even one thought about it since 2014. I had AI and used it to read endless thousands of pages about thermochromic chemicals and the deepest sciences of the receipt printer.
I invented my own re-writable receipt paper, my own custom receipt printer components, and a thermochromic electronic display. All of it worked, but none of the inventions could be perfected to the level that they could be considered a miracle.
I knew I could make a screen with this since June, but I did not think I could make a miracle screen of super low cost for a free computer. I decided to research it anyway, and I made tons of prototypes, knowing they would not be a miracle but would be exciting to see still. I made UV coated paper and tested it to confirm a real miracle screen could be made from this, but the electronics components I needed didn't exist yet. I theorized a MicroLED array to be a potential candidate for being the miracle component, but I would need tens of millions of dollars to investigate that. I designed a custom circuit board with an array of UV LEDs for more research, thinking it would be the only way to inspire other entities to perform scientific investigation into re-writable receipt paper
I had given up on my UV research after reaching every conclusion and theorizing every prototype that I could. I started building a pocket computer with a regular LCD panel. I bought some tiny LCD panels, and while working on my pocket computer lcd circuit, I randomly remembered I could shine a UV light through an LCD panel. I thought, oh my god. How did I not think of this. This is the craziest thing I have ever thought of. This could save the world. Oh my god... I then quickly pulled out a transparent LCD from my parts and shined a light, but it did not work. I put my photochromic paper prototype on my 3D printer LCD, and it perfectly inscribed graphics that looked clear and stayed on the paper.
I finally got an email back from an LCD manufacturing company that could manufacture UV LCDs. Before this, I had been ordering and testing regular LCDs for my pocket computer. Most LCD factories did not have UV LCDs as one of their products. I had emailed many factories since the day I solved to use a UV LCD for my re-writable receipt paper to see if any had the capabilities of manufacturing a custom size and resolution UV LCD. Aptus Display was very knowledgable and said they could actually make a custom size and resolution UV monochrome SLA 3D printing LCD panel. However, it would need hundreds of thousands of dollars to over a million dollars of startup costs to modify their factory and equipment. I decided that some corporations, people, organizations have to use my blueprints I solved to get investments and/or crowdfunding to make the custom LCD. Then the LCD panel could be mounted in a UV Paper Scroll Computer and brought to the public world markets.
The only way to make the magic UV Paper Scroll computer come to the public world markets is to spread the word of this concept to big crowds of people, investors, and make a company or organization to sponsor its manufacturing.
