could easily be programmed in. I was already thinking of experimenting with filters.. printing a black case to go with it shouldnt be a problem
The print could have buttons to trigger different filters.

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…
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…
I would pay money for said course. I'm trying to piece together my own homegrown manufacturing curriculum through a combination of books, googling, diy projects, and YouTube. I don't expect to create world class engineering marvels on my own, but to be able to develop such a polished finished product as OP would be incredible. Any tips on where to start as far as 3D modeling and enclosure design goes?
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.
Don't forget the Harry Potter branding association. That's what will end up bringing in the big bucks.

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.

"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.

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.
Tangential, but at some point of the last 15 years I thought the music industry might move to distributing what amounts to dedicated MP3 players/USB sticks. The simplest ones would be squares with album covers (shrunk like CD covers have shrunk from vinyl), but artists could get 3D creative. You could wear your music in necklaces or in your belt. People would flock to these things as conspicuous consumption (as they…

ya I enjoyed that trick too, it was the first time I had tried it but it worked really well.. You can get the traces to be really fine though I haven't measured the actual doable resolution
Very cool - what settings did you use, and did you have any issues with the copper underneath being reflective? I was thinking of trying this with a K40 for some simple single-layer designs that don't merit waiting a few weeks for fabrication, but I'm a little worried about how shiny and conductive the underlying copper is.
Nice little project, I can only imagine the amount of hours it took to complete, but it is definitely a nice demo of the creator skills. Congrats.
"print" = transfers image data to a removable screen "GIF" = short video
The word print has meant many things throughout history: https://en.wikipedia.org/wiki/History_of_printing The most broad definition: To make an impression or set a mark upon a surface. You could easily call this printing.
