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.
How about actually printing, then laminating on a lenticular surface providing a "GIF-sized" short moving-image effect? [edited per comments]
I presume you mean "lenticular" - which would be a very cool (and possibly mass-producible) alternative. I wonder how you might go about performing the lamination inside the camera... Perhaps you could feed it a pre-laminated sheet that is thin enough that it can be printed on the reverse side?
Recall that these kinds of "motion picture cards" have been around for decades; at least 40 or 50 years, maybe longer. If such a camera (or even a home-based process) could have been built for consumer use, it probably would have been sold. The fact that it wasn't, and the fact that even during all these years there haven't been many manufacturers of such images, should give you an idea of how difficult registration of the image stripes with the lens can be. A purely mechanical process (printing the image onto some kind of paper, then laminating the lens over the top) probably can't be easily (or cheaply) done - otherwise it likely would have been.
That's just my take on things, of course; maybe I'm completely wrong, or there's some method or such I am missing that could make the system easier to build today? I do think the idea of "reverse printing" might be a step toward it. I can't think of how you'd build such a thing to be hand-held, but I can imagine a desktop-sized machine being potentially possible (again, using some kind of close-imaging camera or some other method to register the printing of the images with the individual lenses on the plastic).
Hah, not exactly what most people think when you use the word 'print' but then again ... People have asked what is the impact of 'free' CPUs. Something Dave Rosenthal realized way back in the 90's was that the electronics for driving a display could be printed on the margins of the display and eliminate the need for a separate controller board. Having watched the evolution of displays and seeing Mary Lou Jepsen's wor…
a sheet for a polaroid costs maybe $2 now, some of them even include a chemical battery to power the camera. it seems very plausible to me that a printed display/controller could hit parity with that.

Make the carts NFC and turn Share on when you remove it. You could Tap to swap whatever gif is currently displayed on someone else's cart. That's probably easier than dirt cheap, disposable displays.

PixelQi! Are they finally going to put out a product anytime soon, do you know? Their low-power daylight-friendly monitors are only available on eBay as far as I've found.
Does anyone know if there any other initiatives beside PixelQi and e-ink displays for producing (modern) displays that can be used with passive light? It would be fantastic to be able to bring my laptop into the sunlight for work. And with the expectation of greatly improved battery life.

Pretty neat. Crazy it uses an adhoc wifi network to communicate between the camera and the cartridge. Seems overkill for a battery powered device when they are already plugged in to each other physically.

My first thought would have been to connect the two PIs with a serial interface. Sure, that's another two pins to connect between camera and cartridge, but on the surface it still sounds easier than setting up a reliable ad-hock wifi. The fact that it would use magnitudes less energy is a bonus. Of course it might be that OP evaluated that and decided against it for good reasons.
But then you need to worry about other things and it's also likely much slower. Ethernet just works it's an established protocol and there aren't that many easy ways to transfer files other than it today that work out of the box and with any combination of hardware and software.
Serial I/O is common Hello World example for Raspberry Pi. I think you have to worry about less things than adhoc wifi networks.
> likely much slower
It's slower, but not much slower. The baud rate can be set up to 4,000,000, where a megabyte would transfer in 2 seconds. These "gifs" don't seem to be more than 10 seconds long, so they should be less than 1 MB, judging from random Giphy mp4s.
If I add up the parts of the cartridge, I come to around $88 (including a $35 touch screen). The demo makes me wanna take a picture like that and give the cartridge away. Maybe if it can get under $10 that would be feasible? And before that, at $20 or $30 they could sell them at theme parks where they take your picture in a roller coaster.
The price of his battery and power converter are pretty insane, and a Raspberry Pi is convenient but overkill. Given a more price-conscious part choice and at least some volume (since what's the point in building only one cartridge), you should be able to get that to $5 plus display fairly easily. Suitable displays can be found for $10 from Amazon (shipped from China). So you can probably home-build it for $15. If yo…
This is one of those projects that at first, is easy to dismiss as "silly" or "useless". On the surface, sure. But looking at the imgur album and reading the comments (and I would imagine going to the website, etc - which I haven't done), it becomes clear (and the author even says so on the album) that this project ultimately served a larger purpose: From start to finish, this project has helped the person develop a…
