The Hacker News hive mind is real! I was just reading about JSD the other day after reading about KL divergence...seems like a nifty measurement device for things like sim-to-real evaluations in robots (the reason I was going down this rabb

same! I did some river/lake sailing as a kid on the East Coast but now the urge is calling to me! I remember the "righting the boat" test being the scariest/most fun part of the experience -- super glad I went through th

I've been super interested in sailing since moving to San Francisco and running around the marinas/Embarcadero. Did some digging and found a sailing school that I haven't asked about classes (yet) https://www.spinn

mold making is also pretty complicated -- anything in the 1,000-1M parts produced will _probably_ be an aluminum mold (cheaper than steel) but they're still heavy and large to keep around. I haven't met any injection molding shops

This scratches a corner of my brain I didn't know I had. It's the start of the month and I'm writing investor updates, and seeing an author who...wants to treat writing a book like it's a startup and a book advance like

I fed TRELLIS an image of the left side of my Vespa, and it correctly (mostly) added exhaust on the other side. Super, super cool to see -- really hyped for what this means for 3D representations!

Half of college I'd take the Crescent from Philadelphia to Atlanta, then back at the end. It was great -- you could bring on as much as you could carry (I brought a beanbag chair my junior year) and the food was always good. You meet s

That's another very, very interesting case we thought about tackling. That sounds like something that's ripe for transformer-based vision models to keep the overall size of the model down. What kind of timescales do you get when m

Dude yes exactly!! It's so incredibly frustrating when you're past final assembly of some system, and only then do you see a defect that requires a teardown! You touched upon a really fun piece of defect detection -- quality metri

Injection molding houses are heavily concentrated in LCOL areas -- but it's a massive market, so, so much of modern materials are plastic that there's a lot that's done in the US/Canada/Mexico, in North America, and

LLMs like GPT-4o have some pretty impressive image performance. It can actually pick up some of the more obvious defects on our buckets (Steph tested it out just now). Two problems though with the OpenAI approach: 1. You'd need a cloud

> Nice! I have so many questions.. How stable is the injection molding process once it's fully proven out, up and running? Is it a bathtub curve shape, do defects keep randomly popping up? They tend to pop up randomly -- mold wear i

I'll answer in reverse order. Making synthetic data from a 3D model is really nothing too special - it's just a tiny subset of what video game engine does. But there's one extra step required for defect detection: you need to

by lasermatts 2y ago
Regarding pricing: we we charge at a per-model basis -- so the workflow when you're ready to retool your line, send us the CAD and we'll send you the defect detector model and the bill. We're still working out if there's

You nailed it - when the part comes out of the mold, it slides down a chute onto a conveyor belt. From here, the arms themselves change depending on the supplier (Kuka/Fanuc/Universal Robotics/Yaskawa...there are a lot of pla

A deep chill ran down my spine as I remember all of those VBA tools I updated/generated during my first internship... some of those are still being used in some semi-industrial applications.....

This really hits home. I recently quit my job as a robotics engineer -- and I've been painting a lot more and have noticed the quality of my work has gone up. In the past few weeks I've had more sales than I had in the year prior
