Wild times when running a 3D printer feels easier than dealing with those old 2D ones. 😎

Congratulations, Tomáš Mikolov!🏅
Our co-founder and Chief Scientific Officer has received the Medal of Merit from @prezidentpavel🇨🇿 for his work in science and technology.
With more than 200,000 citations and over 20 years in AI, Tomáš is among the world's most accomplished AI scientists. He was among the first members of Google Brain and Facebook AI Research, and his work includes algorithms for scaling neural language models to large datasets.
Now we’re building together the next generation of AI algorithms that increase intelligence while reducing the cost.
Congratulations, Tomáš. Well deserved 👏
The capacitance value in the schematic should be updated dynamically to reflect the actual capacitance.

My wife told me we’re going to a movie themed event next week and that I should find myself an introvert friendly costume… Challenge accepted.

Should a USB-C connector's shell go straight to ground, or through an RC (1 MΩ ‖ 4.7 nF)? Open boards are split.
I hit both with a simulated 8 kV zap. Either way, 30 A lands in your ground. The cap is just left holding 249 V.
Answer: straight, unless the box is earthed. 🧵

You found it. 🍌
The banana at the Next Gen Roadster reveal wasn't an accident. It was an analog stopwatch.
A laser triggered the drop the instant the tires started to roll. We hung it at exactly the car's 0-60 time at the time of 1 second.
Banana hits the ground. Car hits the laser wall. Same frame.
Here's how we did it 🧵

The new Roadster's rear drive unit is unbelievably small for something producing 1,341 hp.
Lars Moravy says its two motors produce more power and torque than all three in a Model S Plaid, in @Hagerty’s video.
Each motor has its own inverter and planetary reduction gear, allowing independent control of the rear wheels without a conventional differential.

Should you cut a hole in the ground plane under the pads of a USB-C or HDMI connector? Some engineers swear by it, others say never.
I simulated it 327 times to settle it.
Answer: yes, when the pad is wider than the trace. And make the hole exactly the size of the pads. 🧵1/12

Turns out you can get laser cut sheet metal ~10x cheaper by pretending it's a solder paste stencil and ordering from @JLCPCB.
Suck it, SendCutSend!
