And Bitcoin doesn't?

Who said anything about Bitcoin?

"Massive amounts of electronic litter" and "amazing how technology has advanced" into a mad rush to waste resources and energy reminded me of this fire, and all the obsolete PC's and GPU's and ASIC's and coal power plants littering the landscape due to Bitcoin mining:

Bitcoin mining consumes enormous amounts of electricity, which is why miners seek out locations that offer cheap energy. The Ordos mine was set up in 2014, making it China’s oldest large-scale bitcoin mining facility. Bitmain acquired it in 2015. It’s powered by electricity mostly from coal-fired power plants. Its daily electricity bill amounts to $39,000. Bitmain also operates other mines in China’s remote areas, like the mountainous Yunnan province in the south and the autonomous region of Xinjiang in the west.

Coal is a killer in China. Coal burning and the secondary effects of sulfate and nitrate contribute to almost half of the dangerous air pollutants in China's polluted cities, compared to 20% from car emissions.

What about printing little flip books? :) Cool project in any case.

would have to invent a high speed mini printer for that.. next project perhaps :)

I suppose something like an Instax Share printer could work. Not cheap though.

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 :)

How much time did it take you to make this from start to finish?

The breadth of skills needed to do this all yourself is quite impressive!

How about actually printing, then laminating on a lenticular surface providing a "GIF-sized" short moving-image effect? [edited per comments]

Well there we go. Just fit it into a handheld printer.

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.

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?

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 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…

I agree, this is something I built entirely with off the shelf parts so the cost is bound to balloon.. The cost can be brought down significantly like you said

I think most of the cost is just the tradeoff between getting stuff tomorrow, or one month later from china at a fraction at the cost. If money isn't an issue, paying more to get stuff faster is certainly more productive.

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…

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 already do with tshirts, pin-buttons, etc) which would offset piracy.

All of this is viable and cheaper than ever, but the culture has moved on.

thanks! it took me about 4 weeks once I started building.. many nights prior to that just lying in bed planning and visualizing

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
