To the spirit pilots I’ve met recently, Thank YOU for helping us tackle this nightmare of a week with skill and precision, and a sense of humor even.
I sincerely wish you the best, and if we happen to cross paths again, which we most certainly will, remind me of your city-pair and Tail Number. 🫡

@younghyo_park @uddupa I printed a bunch of these cubes for an AR asset tracking project. Printed my cubes in Stratasys J55 Prime. Circa 2024. Such an obviously awesome idea!
English
Nobody asked but I'm going to talk about that cuboid in the video anyway :) It's a 3D-printed, 6DoF-pose-trackable cuboid, programmatically generated and tracked with this! github.com/younghyopark/a…
This little cube really helped us isolate control issues from RGB vision problems and clearly realize the importance of low-level controller design decisions.

What's different between these two BC policies? It's the same architecture, training budget, and data collection setup — the only difference is the controller gains! Controller gains are an understudied design parameter in robot learning. In our new work (w/ @BronarsToni*, @pulkitology), we show how they act as an inductive bias across BC, RL, and Sim2Real transfer, with real consequences on performance. Here's what we found 🧵 * Equal Contribution 📄arxiv: arxiv.org/abs/2604.02523 🔗website: younghyopark.me/tune-to-learn/

People always miss the third option which is just becoming a mechanical/electrical/firmware engineer and getting the mid-6-figure salary while still touching metal

BREAKING: Chris Power CEO of Hadrian says “Everyone should tell their kids to quit college & get welding degrees” "The country needs you." “The next 2 decades is blue collar.” Hadrian is also bringing back Pepperidge Farms & baking. “All the white-collar jobs are going to get automated.” “We’re gonna see massive hyperinflation in blue-collar salaries.” "I think one of the greatest opportunities for private capital — apart from public-private investment alongside the Department of War (@DeptofWar) — is to build Chick-fil-A’s & bars around all of our factories. That’s free alpha. Please come set up franchises around all of our factories. We need to eat so we can work harder for the country."

just ran claude code with --dangerously-skip-permissions, and it raised a Series C

I think this is the cheapest solution to have a ISO 5 clean workspace at home?
Very tempted....

@Lola_lmao7 Fun fact. This circle letter here on the logo of Wikipedia is “vi” or “wi” in the Kannada alphabet.

my copilot agent started thinking in Kannada, a 5th century Indian language. Apparently ವಳಿಸಿದ್ದಾರೆ means 'they have bent' or 'they have curved/turned'

@jlcjak @nick_mccleery Couldn’t be further from the truth

@nick_mccleery The average mechanical engineer complains 30 times a day that their cad designs break. A good mechanical engineer understands how cad works and their designs break 10x less
English
CAD is not for people who no clue how computers work, FEM is not for people that don't know mechanics, EM simulators is not for people that don't understand EM.
I see this all the time, most of my problems come from being to lazy to go one layer deeper in understanding
jlcjak@jlcjak
you should always understand at least two layers of abstraction below what you're working on. Trying to design an analog circuit using TI ICs without understanding how op-amps work AND how transistors work is equivalent to cooking without knowing how individual ingredients taste
English
@jlcjak The average mechanical engineer does not have the faintest idea how any of their CAD systems work.
I'd bet most professionally employed design engineers have never heard of NURBS, b-reps, surface-surface-intersection, geometric constraint solvers etc.

Can our phones be used as a 3D scanner for CAD? Has anyone tried it? Is it reliable?

I’m looking to talk to people who have built a hardware company.
I'm starting out, and I'd love to hear "post-mortem" stories. I want to know what actually kills a hardware startup before I hit those same walls.
Specifically, I want to ask:
The Production Gap: What was the actual delta between your "Golden Sample" and the first 1,000 units?
Hidden Burn: Where did the capital actually go, outside of the obvious R&D and inventory costs?
The "China Tax": How much did you spend on re-work, expediting fees, and QC that wasn't in your original spreadsheet?
Tooling: Did you actually own your molds, or did the factory hold them hostage when things went south?
English
gonna see if I can make budget zemax with claude code (so far so good?)

@andrewkornuta “Openclaw but for sourcing” is just solutionism. In strategic sourcing you’ll need humans with skills to do spreadsheets, work the phones, send emails, occasionally get on a plane to vendors to get shit done. If one’s trying to abstract that away they just don’t have enough drive

Manufacturing X, tell me the 347 reasons why this will fail in five minutes or less for a prize.

Reframe (@usereframe) automates the hardware supply chain, starting with procurement. Upload your BOM, connect your ERP, and their system will handle sourcing, ordering, vendor coordination, delay resolution, and real-time build plans. Hardware procurement still runs on spreadsheets and emails, until today. Use Reframe to automate end-to-end procurement and keep your hardware teams lean. Congrats on the launch, @bryanzin7 and @EricWiener5! ycombinator.com/launches/PU7-r…
