Title: I made a thing!<p>In 2014, I was holding a stack of iPhones and thought to myself:<p><pre><code>    &quot;Hey, if I had each phone display a playing card, I could click a button and they&#x27;d shuffle themselves&quot;
</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&#x27;d share :)
