There is demand for it. There are lots of people trying to buy them, find them, and even make them DIY style, so why no one is making them is a mystery. Could there possibly be reverse pressure because of the market for other screens?

Reliability, generally. Consistency, afterward. Cost, third. OLED was hung up for years because the blue pixels had 1/100 to 1/10 the lifetime of the red and green one. In addition, you would be stunned at just how good our visual system is at picking out imperfections. Anything less than perfect (especially involving green) will produce complaints. After both of those, you can talk about cost and efficiency.

That's informative, thanks.

And I think you're point is on point: people would buy these and not be happy with them, because they want a real monitor. There's also a group of people who want them just to be able to ready articles and write articles (and code, etc) outside, and without charging a battery as often, and would be happy with lo-fi graphics.

Definitely agree with you.. this was just a concept for me that I was able to build with off the shelf parts but this is exactly the type of discussion I was hoping to get going..

I have a feeling that personal displays (as with cellphones now) will continue to exist until man stops existing. I imagine the opposite trend will occur, where each person owns fewer and fewer display devices. I can't imagine a justification now, or in the future, for buying some single use display. Once we get to a nice head mounted AR system, it would be very silly to have anything more.

People like having something special and permanent. All those pictures on your general-purpose computing device? They're gone as soon as you lose the device, get ransomware, and/or temporarily run out of money to renew the cloud storage subscription.

A polaroid picture that starts playing as soon as you attach it to a suitable power source (please make it something standard like an AA battery or USB cable), on the other hand, is something you can keep in a box in the attic for your grandchildren to find after you're gone. It's not just a display, it's a read-only snapshot and air-gapped backup of a moment of your life.

That (i) is absolutely irrelevant to the discussion at hand and (ii) a completely fallacious argument, since Bitcoin mining amounts to less than 0.01% of the world's energy consumption, providing a useful service in return (compare with gold mining, which is actual mindless busywork and consumes way more energy than Bitcoin does.

> less than 0.01% of the world's energy consumption Actually, it's 0.08% and rising. The energy for 1 transaction could power almost 6 U.S. homes for a full day. https://digiconomist.net/bitcoin-energy-consumption

Oh and I sent with a 3c txn fee!

What's the cheapest you could make the cartridges assuming mass-production?

havent worked that out, would probably need to get in touch with a manufacturer for assuming it's atleast 1/4th of what it is now, perhaps $20. Perhaps even less

a cheap dumbphone that retails for less than $20 has a BOM of around $5 and has CPU, battery and screen. so $20 retail for your cartridge is achievable in volume

OpenSCAD! http://www.openscad.org/documentation.html It might not be where you end , but it's a great place to start. (fwiw, I do all my 3D design with OpenSCAD. Been using it since 2011.)

Very cool! Thank you! How do you find it helpful to think in terms of code that generates a design vs. jumping right into the visual aspect of a design (I'm assuming the latter is how a typical 3D design program works)? In other words, why do you prefer this to other more traditional 3D design programs?

The parts in my designs are fairly simple and mathematical (rectangles with holes like Lego Technic), which makes them good candidates for OpenSCAD. My product designs, though, are first made by hand in a playing-with-Lego-like way (3D printing parts made in OpenSCAD as needed). Beyond that, I like having the precision of source code for my designs. Like source code, I can easily check them into source control and track changes over time.

Very cool. If you can make that cartridge dirt cheap, you will have invented an exciting new technology. Build a V2 with cheaper tech, change your wording a bit as to what the device does, keep the polaroid link a little bit, but make it your own and then I think you'll have something that could kick ass on Kickstarter.
