Show HN: Trading cards made with e-ink displays
I made a thing!<p>In 2014, I was holding a stack of iPhones and thought to myself:<p><pre><code> "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves"
</code></pre>
I pared that idea all the way down to this: trading cards made of e-ink displays.<p>Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10.<p>In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the cards using stable-diffusion.<p>HN always seems to appreciate new uses for e-ink. Thought I'd share :)

Show HN: Bulwark Passkey – A virtual Yubikey-like device for 2FA or WebAuthN
Hey y'all,<p>This is something I've been working on for a few months. It is a passkey system, similar to Apple Passkeys or a Yubikey, but it is entirely software based so you can sync credentials between devices.<p>Passkeys (and FIDO devices in general) allow you to use public keys instead of passwords or codes to authenticate. For instance, you can just click "Approve" on the device/software instead of having to copy a code, and there are no passwords to phish. This is a new piece of tech, so website support for logins are still limited, but it can currently be used for 2FA anywhere a Yubikey can be used.<p>Bulwark Passkey emulates the USB device in software, which allows you to sync credentials as well as copy them out. This is less secure than a dedicated hardware device, where credentials can never by copied or removed from the device, but it is much, much more secure and usable than passwords or one-time codes.<p>Please take a look, and I appreciate any feedback you might have!

Show HN: A userscript that adds archive URLs below the paywalled HN submissions
This userscript adds archive URLs to the metadata section of HN submissions without breaking the immersion. Here are 2 screenshots: <a href="https://imgur.com/a/PdUu6oG" rel="nofollow">https://imgur.com/a/PdUu6oG</a><p>GreasyFork: <a href="https://greasyfork.org/en/scripts/452024-hacker-news-anti-paywall" rel="nofollow">https://greasyfork.org/en/scripts/452024-hacker-news-anti-pa...</a><p>Source code: <a href="https://github.com/MostlyEmre/hn-anti-paywall" rel="nofollow">https://github.com/MostlyEmre/hn-anti-paywall</a><p>Now let me overexplain.<p>-Why?-<p>I never liked paywalled articles. I understand where they come from, but I don't like where we cross our paths.<p>This is why I don't use major news aggregators anymore. Instead, I spend my "catching-up-with-the-world-time" on Hacker News. However, Hacker News (HN) also has its fair-share of paywalled articles. (<i>Around 11.6%</i> according to my short-lived, half-assed attempt at measuring it. See my super old data <a href="https://hpa.emre.ca/" rel="nofollow">https://hpa.emre.ca/</a> I tell the story below.)<p>-First try-<p>Around a year ago, when I ran the above experiment, my goal wasn't to run that experiment. It was during my self-teaching & career-changing process, I decided to build a React HN clone. To make it stand-out from the bunch, I added a paywall feature. It would detect paywalled articles and would add an archive URL into the metadata.<p>The issue with archiving is unless someone archived the link before on the {archiving-project} then the link is most likely not archived. So me sending people to those projects meant nothing. It kinda meant something for me from an ideological standpoint but I assume you are not me.<p>This rubbed me the wrong way. I decided to build a backend (See <a href="https://github.com/MostlyEmre/HN-Paywall-Archiver" rel="nofollow">https://github.com/MostlyEmre/HN-Paywall-Archiver</a>) that would scan the links and automatically to detect paywalls close to real-time and submit paywalled ones to archive.is for archival. I used Nodejs, Firebase, and React. I was -still am- really proud because I believed it was doing public good in terms of digital preservation. Only 1 person needed to run this script to benefit everyone. As an extra, I was curious on how many paywalled articles were being shared, by whom, at what time. So I also created some analytics functionality to gather the data. And later created a UI to present it.<p>HN-Paywall-Archiver was great but I stopped running the backend at some point. Because at that point couldn't find a way to continuously run my backend code on some platform for cheap or didn't try hard enough.<p>P.S. Recently I've been thinking of remaking this version with Cloudflare Workers.<p>-Hacker News Paywall Archiver Userscript-<p>After almost a year, I got into userscripts. Super great super awesome concept. People seem to hate javascript unless it is presented as a userscript. So I decided to get my hands dirty to create a simple solution that solves the paywall issue on HN without breaking any hearts.<p>My solution is not perfect as it had to be simple. But here's the rundown.<p>Pros:<p>- Does not beg for attention.<p>- Simple code, simple concept.<p>- Unintentionally, indicates which submissions are paywalled without you interacting with anything.<p>- Not-yet-archived archive links can make you feel like you are contributing to the society after you click on the "archive this URL" button on project page.<p>- Uses HN html defaults, so I hope it plays well with the HN skins/plugins/userscripts you use.<p>Cons:<p>- It doesn't automatically archive the links.<p>- It uses clone of a static list of paywalled websites sourced from a popular Chrome extension. (<a href="https://github.com/iamadamdev/bypass-paywalls-chrome/blob/master/src/js/sites.js" rel="nofollow">https://github.com/iamadamdev/bypass-paywalls-chrome/blob/ma...</a>) So changing the paywall list is slow and manual.<p>- No guarantees of archived links actually having the archive readily available for reading. Though there are currently 3 projects added, so it should be enough for most links.<p>So, there you go. I hope you enjoy it. It can break occasionally due to changes in news.ycombinator code, if you let me know on Twitter, I can fix it ASAP. Otherwise you have to wait until I notice that the script is broken, which can take quite a while as I browse HN on mobile.

Show HN: Feuille – a fast, simple socket-based pastebin
Should be considered as a usable WiP for now.
I still need to tweak and fix some things in my code.
I'd love to get some feedback!<p>See <<a href="https://bin.heimdall.pm/" rel="nofollow">https://bin.heimdall.pm/</a>> for my personal feuille instance.
Feel free to play around with it :)

Show HN: Widget.json and Widget Construction Set
My friend and I just finished this project last week. I'd love to hear your feedback.<p>widget.json brings a dynamic window to the web to your device's home screen. It's kind of like RSS for widgets, you make a widget.json for whatever web data you want and then subscribe to it in Widget Construction Set, our iOS widget.json viewer.<p>We've made image of the day and word of the day widgets, Youtube channel widgets that show the latest videos, RSS widgets, Prometheus counter widgets and more. You can imagine a GitHub CI widget showing the last build status with a link to view it. Friend groups could make a shared scratch pad of text and images. Househoulds can make a shared TODO or grocery list widget. Widgets can use local device launch schemes which enables widgets to initiate text messages, calls, emails, shortcuts apps, and more. With this, you can make a widget that shows images of your favorite people and when you tap their image it FaceTimes them. If you're worried about Twitter, you could even make your own one-way Twitter replacement where your text and images show up on your followers home screen!<p>Ideally, sites add a widget.json feed alongside their RSS feed. widget.json files have a one-click subscribe link to easily add them to Widget Construction Set. This gives sites and creators a simple, direct connection to their users without the need of building a separate app or having their users remember to visit their site. For Patreon or other user-supported creators, they can offer private widgets that are only granted to their supporters.<p>We couldn't figure a way to make a business on this, but we liked what the technology enabled so we're releasing it all for free, with the exception of a one-time $2.99 purchase to view private widgets. Though since the widget.json format is open, if $2.99 is too steep, people are free to make their own private widget viewer as well.<p>Widget Construction Set:
