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.

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.

And have a button on them that cycles through previously taken gifs.

I've long imagined something like that: a card-sized (including thickness) full-color display devoted to displaying, say, an entire movie. Given ultra-thin displays like OLED, dirt cheap storage, and "free" dedicated processing, you could hand out videos like sales brochures or cheap paperbacks. Amazing how technology has advanced.

I imagine that we will eventually reach this point:

Fun to imagine that the Harry Potter Universe is really just a bunch of people that have inherited super advanced nano technology from some alien race that long ago arrived as refugees escaping some galactic war that devastated their planet.

After millennia they've lost touch with their history and only their access to their old technology remains. Technology that can only be accessed via a DNA marker.

This type of technology is able to bend space and time, hence the ability to jump through space.

Hi guys, I am the creator of this camera! happy to answer any questions.. didn't know it was doing so well here on HN :)

Will you develop a noir cartridge for making beautiful black and white error diffusion dithered animated gifs?

Cartridge is easily big enough to contain a camera (see phone tech) so I'm not sure it makes much sense to make a system which separates the two. A digital photo frame with built-in camera seems more plausible, cute as it is to emulate an old Polaroid machine.

Yeah except that would create massive amounts of electronics litter..

And Bitcoin doesn't?

Overkill but much easier from a technical point of view considering what was used to make the cartridge.

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.

To me it describes excessive concern with minor details and rules. but thats none of my business tho

I think the problem is "what words actually mean" has become a minor detail to some people. My high school English teacher would not have accepted "language evolves" as an excuse for things like confusing "then" and "than" and not knowing the meaning of the word "literally".

And then there's the "what file extensions actually mean" problem.

"Some kind of custom connection" is the real issue here.

I'm imagining a row of pins along the back or bottom of the cartridge, or an edge connector, like in the old Nintendo cartridges.

Remember how after a few months you'd always have to clean those Nintendo cartridge connections otherwise the game wouldn't load?

My point is that making those types of custom, physical connections are kind of a manufacturing nightmare. If the hobbyist that did this was able to do it with WiFi with no need for more manufacturing and making sure the sled would be able to reliably push the pins in every time, then WiFi was the right call in my eyes!

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…

How about including fusible links and resistor ladders into the OLED so you essentially "burn" the picture into the display?

Depending on the resolution... and people would find anything less than 300ppi grainy at this point... there's not much room around each sub-pixel. A pitch of 60-80um is typical and there's not room to do anything like a resistor ladder or fuse with TFT transistors (3um min gate length) in that area.

The cost&size of flash and a TCON to play back a moving image is pretty damn low in 55nm from SMIC though. Less than a buck certainly. OLED and battery will be your dominant costs.

It's probably actually mjpeg - at least that's what I would use.

Shoot videos like it's 1999?
