5/ Move every fix one level up the list when you can. IEShowdown, a game I built, lets you practice calls like this: https://t.co/MLws8hbjEL

Most poka-yoke ideas stop at a sensor and a buzzer. Here's how I rank error-proofing on an assembly line, strongest first. 🧵

4/ Inspect downstream. End-of-line test on an EV drive unit catches it, but the cost is already built in.

SpaceX has just announced that it has signed a major deal with SINGULUS to manufacture advanced, high-efficiency solar cells for its Starmind satellites at its facility in Bastrop, Texas.

The first production line is expected to be delivered in the first half of 2027, with plans to scale to more than 100 GW of solar cell production equipment.

“We have signed a supply contract with SpaceX for a turnkey production line for the manufacture of heterojunction solar cells.”

The agreement is part of a broader strategic partnership that could include multiple additional production lines as SpaceX rapidly expands its satellite manufacturing capabilities.

Stopped by Giga Texas and stood next to Optimus.

Here's my IE take: when a humanoid joins a line, the rules don't change.

You still measure the work. You still balance stations to takt. You still need standard work, because a robot repeats exactly what you give it, waste included.

Robots don't remove the need for industrial engineering. They raise the bar for it.

What's the first station you'd give a humanoid?

5/ Rebalance on the floor with the operators. They know which elements really move cleanly. Which station on your line is hardest to balance?

[Arturo Salcido @Asalcid0]

Line balancing looks done when the yamazumi chart is flat. Here's how I check a balance will actually hold on an EV assembly line. 🧵

4/ Check precedence before moving work. Torquing a bracket before the harness is routed looks efficient on paper and creates rework at the next station.

Tesla has submitted a new letter to NHTSA, urging the federal government to modernize U.S. vehicle lighting regulations.

Tesla argues that existing regulations were designed for traditional headlights, not modern matrix LED systems that use vehicle cameras to detect other vehicles, pedestrians, and cyclists and dynamically adjust light beams to improve visibility and reduce glare.

Tesla also wants regulations to account for lighting improvements delivered through over-the-air software updates and is pushing for automakers to have greater representation in shaping the new rules.

Tesla: "We do not treat lighting as an isolated supplier module whose only “sensor” is a dusk photocell. Lighting behavior is informed by the same surround-camera suite that continuously observes the driving scene: oncoming headlamps, preceding taillamps, pedestrians, cyclists, lane geometry, and ambient illumination. Semiautomatic beam switching and adaptive driving beam functions are therefore scene understanding problems, not binary light-threshold problems.

Tesla has concerns about NHTSA’s proposed composition of the advisory committee tasked with reaching consensus recommendations. Specifically, Tesla urges the agency to increase the number of individual vehicle manufacturer committee members from the current proposal of just two representatives. The current proposal does not accurately reflect the interests of individual motor vehicle manufacturers, particularly when those interests will not be represented by a trade or industry association member of the committee."

Tesla has officially started construction of its massive new $10 billion solar manufacturing facility near Houston, Texas!

Construction is expected to finish in 2028, with commercial operations starting in Q1 2029. Total direct and indirect economic impact of the project is estimated to generate ~$6.4B in state and local taxes, and increase State of Texas GDP by ~$107 billion.

The factory will be a vertically integrated solar manufacturing facility, and it'll include:
• Wafer Manufacturing
• Ingot Manufacturing
• Coating
• Metallization and Printing Lines
• Cell Testing and QC
• Automation and Material Handling
• Cleanroom and Production Support
• Site Infrastructure
• Chemical Storage and Delivery
• Utility Infrastructure
• Environmental and Safety Systems
