If you like this, you'll also love Mitxela's fluid simulation pendant [0], and likely all of his work! I'm consistently astounded by how informative and enjoyable his stuff his. He shares so much, so freely and it's so well produced, with a lovely voice to boot. Inspirational! Watch his vids, read his write-ups or both! We need more people like this.

+1 for mitxela, dude never ceases to amaze

That was very clearly mentioned and linked in the article, too.

Ahh, today it is my turn to fail the online reading comprehension test! My bad, I'm just very into Mitxela.

Earlier quoted context omitted.

Rigid body simulations are much much simpler. There’s a siggraph course from 2001 [0] which is a bit of a dense read but it will bring you all the way up to a full blown rigid body simulation and understanding the math behind it too. [0] https://graphics.pixar.com/pbm2001/pdf/notesg.pdf

Though in this case there's not much more than 500 points, which even if you scale up is manageable.

It’s less about the number of points and scaling and more about understanding the fundamentals. Any sort of particule simulation (which is the easiest way to get into cloth, soft body and fluid dynamics) requires about the first half of that paper I linked anyway.

i absolutely love the form factor! a similar one was beamu (eink screen, nrf52 with bt): https://nicgardner.com/2020/05/09/beamu-first-impressions/ (this was an actual product, if a bit pointless. i have one still) any others?

Do you use any of the features? This is kinda cool, I love when people pack way too many features into a single product :P

Off topic, but where should one start learning writing physical simulation? Several years ago I ran into this project [0] and got overwhelmed even the algorithm can be written in 88 lines of C++. I realized that out of all CS topics, physical simulation is probably the one I knew the less (not saying I'm a compiler/database expert or something, but at least I've implemented a toy compiler and some basic data structur…

The Nature of Code by Daniel Shiffman is an excellent entry point - it teaches fundamentals of physics simulations with clear examples in Processing/p5.js.

Amazing project, but the font on the back of the card is gross.

That’s cred, man. Real cred.

Wack font. Circuits exposed. Pixels with fat borders between them. An ugly charging port. But more stuff, packed into a small sleek volume than reasonably possible. Working perfectly.

That’s not Jobs. Oh, no. It’s effing Woz.

The guy is a true hardware engineer.

Would love to see more information about how it was built. He must have worked with a company that can do the surface mount assembly?

Electronics can be surprisingly easy and cheap to build these days. He designed the circuit and layout with software called KiCAD (free and open source) then submitted the designs to a fabrication house - probably a popular offshore one - that easily can handle that level of board and component placement complexity. It would probably cost only a few hundred to build and ship, with 1 month turnaround time. You can als…

As long as there aren't surprise 50% tariffs.

Very nice, but probably a bit too expensive to just hand out. I knew a chap that had a similar hardware business card (I don't remember exactly what it did, but it wasn't as cool as this one). I remember that his card was pretty scuffed up, and he insisted I give it back, after he handed it to me. Bit weird.

I'd include a sad tomagotchi that after a week or so guilt tripped you into giving it back, its heart broken, missing its original owner.

The circle works much better for the fluid simulation.
