I know everyone who dares to say anthing about NFTs gets downvoted, but I'll do it. In this case, making the cards an NFT can make this really cool. Some sort of global immortal database where the rarity etc. is defined. Could also have nothing todo with crypto if the dev/publisher pays for the servers.

This is cool. I hope the cost of eink plummets so this is actually viable.

4.2" three color modules are 12 USD on AliExpress without volume discounts. How much cheaper does it have to become to make it viable?

Cheaper than that.

Nice. I've thought of various similar applications (probably because I saw such somewhere). For example conferences require lanyards with passes attached. Most contract with some company to handle all their creation, then also require you (more or less) to use their app to get a schedule, etc. Why not create a generic, re-usable pass (like OP) that attaches to your lanyard, has some basic features at a glance (schedu…

Have you heard of our lord and saviour the Pimoroni Badger? https://shop.pimoroni.com/products/badger-2040?variant=39752... I have one and it's awesome. They upgraded it recently with wifi: https://shop.pimoroni.com/products/badger-2040-w?variant=405... They have similarly-shaped stuff in color too, like the Tufty https://shop.pimoroni.com/products/tufty-2040?variant=400369... and the Inky https://shop.pimoroni.com/p…

This looks really neat. Now I'm tempted to see if I can get one and have a way to render a conference schedule on it. :D

I really hope the Bay Area keeps this attitude, and that other places adopt it if they haven't already: "I live in the Bay Area. I'm biased, but this place is full of awesome engineers building things and you can just walk up to them and ask them to explain everything about their project and they will." Edit to add: It reminds me of Jobs calling up Bill Hewlett at his home as a teen and asking him questions, and Hewl…

I live here too. I'm biased, but 1) this place is not full of awesome engineers, it's mostly full of overworked contractors and newbies with eighth grader syndrome. And 2) you can't just walk up to them and ask them to explain everything about their project. That's a huge security issue and if it were true it would be a lot easier to social engineer places today. Not to say that it isn't possible, but this comment pa…

I didn't mean people who work at Uber explaining how their load-balancing works.

I meant walking up to a super cool music visualization at an outdoor art festival and they guy there happily explaining to me their entire system built out of a node flow diagram implemented on Max but adapted to visual graphics using a plugin called Vsynth.

Or going over to a friend's house and seeing their modular synth system and they happily explain to you how it works for an hour.

Just this weekend I met an amazing engineer with a street-legal steam-powered motorcycle which he patiently explained for an hour.

Earlier quoted context omitted.

To set the record straight, I was the one that reached out to the creator to get his story, because I thought the cards were cool. He would not have spent the time doing this interview if I hadn't asked him to.

And that's fair enough. The larger point of having a platform without a product still exists. And I think this is still something where the idea is cooler than the current reality. Mostly because you can vaguely imagine the coolest version of this and you aren't being asked to put anything on the line for it. Is there some version of this that's genuinely fun and engaging? Maybe so. The potential of non-destructive p…

So, the goal was to build a devkit so that I could use it to develop my own game. I wanted the physical things to exist, so that I could try it out with people and find out which interactions are fun, vs which aren't.

Well the internet liked the idea, and saw some of the same promise in it that I did (plus HN is a sucker for e-ink). With all the interest, and people asking how they can get their hands on one, I ran a crowdfunding campaign to make devkits for everyone who wanted.

Turns out making 25 of something is way more work than making 2 of a thing. The supplier changed the display firmware on me, I had to make things to more exact measurements so parts were interchangeable, I had to write docs and make videos, etc etc. Took a whole year.

Now the pressure is off and I don't owe people products after they gave me money for them, so I can take a break to clear out my backlog of minor projects, then get onto designing my own game, using my own devkit :)

Once I have an actually fun game, I could increase volume and bring down the costs. My goal is to make the game accessible for $80. I'll need the e-ink price to come down a little, and use injection molding instead of resin casting and wood. Plus the base won't need a Raspberry Pi, that's just for my quick iteration. Final product will need to be embedded.

(Almost all the devkits sold were to friends and family, with only a few going to actual game designers. CrowdSupply itself puts in an order for more units along with the campaign, so that they can stock them after the campaign ends and initial delivery is over. Except they negotiate a different price for those because the margins work differently)

>> It just seems that from every angle I look at this thing, I see clear problems with bringing it to market as a viable product.

Yeah, the goal is to make a cool thing, and then make a fun game.

Yeah that makes sense. Got me wondering to what extent it’s possible with something like load balancing too. Maybe meetups don’t have to corner the market on that kind of info sharing

That's very cool. Love seeing these types of things. If they were thinner and wider, I suspect that an almost unlimited number of uses could open up for them.

Wyldcard creator here, thanks to HowToWare for the interview. Since the intention is a children's toy, I'm trying to get the price as low as possible. This display size is cheap because it's intended for grocery store price tags ;) Flat Flex e-paper displays are available but much more expensive. Plus, the magnets in the cards which let them mate to the base take up most of the thickness. I'd have to rethink that phy…

I was wondering where you found some place to do custom screen sizes. Nice use of an existing product shape.
