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?
Yeah, wondering how the LEDs were aligned so precisely. Some kind of silicone grid-like jig to hold them while the solder reflows? Or is it just pick & place robotics doing what they do with precision?

>He must have worked with a company that can do the surface mount assembly He did (there are centroid files in the production folder, which tell the board house where to put the components), but you'd be surprised at how possible it is to assemble something like this by hand. You won't believe me, but I find it easier than through-hole soldering (because you don't have to keep flipping the board over). But there's a…
Indeed, JLC for this one, though I did start off by hand assembling the first version with a 3D printed jig to locate the LEDs.

Re: Ultrathin business card runs a fluid simulation
#86Very 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.

#87If 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.

The circle works much better for the fluid simulation.

Yeah but I guess they wanted to add something in the value for everyone of us while they didn't have ofc the whole knowledge to do so. their heart might be in the right place tbh. But that's my 2 cents.

>But that's my 2 cents. Or is it really ChatGPTs 2 cents? Copy-pasting LLM responses is as useful as posting a "let me google that for you" link. It's a lazy response at a minimum.
