PCB: 135 parts, 514 pads, 4 layers.
An AI harness in VS Code did it all — calculated every part, read every datasheet, drew the schematic.
AI is lowering the barrier to building hardware.
What would you build?

Gemini 4 Argon is here! It is our frontier model built for complex workflows across real-world software engineering, tested across Google's own codebases on real production challenges. There, we have seen an improvement in both developer velocity, with a 35% increase in agentic code, and code quality, with a 30% decrease in post-submit rollbacks.
Rolling out now to Google AI Ultra subscribers, try it in the Antigravity app and the Antigravity CLI. Get inspired with what you can build today ↓

When we started responding to Russia’s operation against our data centers, and when our strikes reached Yandex’s data centers, it suddenly became a little easier to breathe on many social media platforms. A lot of people noticed it. There was less hate, less division, and fewer provocations.
Because there were fewer bots. And it’s pretty clear where those bots were coming from – if they disappeared when Yandex went offline. This proves, again and again, that Europe is not the source of the problems. Europe is not the one making everything more difficult.
Most importantly, we need people in America, every morning, when the day in Europe is already moving toward evening, to really see what is happening. To see the truth.

L'ensemble des chaines d'infos devraient être tournées vers Sophie Adenot et pas sur des cons de lycéens et d'extrémistes de droite ou de gauche nous offrant un spectacle intellectuel pitoyable.
Après un voyage de 27 heures et un amerrissage dans le Pacifique, Sophie Adenot est rentrée en Europe, plus précisément à Cologne en Allemagne où se situe le Centre européen des astronautes. Elle s'est exprimée devant la presse mais n'a pas pu retenir son émotion en évoquant ses 235 jours passés dans l'espace.

[🇫🇷 version FR 👇] Back on the ground, back home in Europe, and welcomed by family, friends, colleagues, journalists and so many people here in Cologne. What a way to come home! 🫶 Thank you to everyone who was there, and to all of you who liked and shared my posts throughout the mission. You’ve helped shine a light on human spaceflight and what it can bring to life here on Earth.
It took countless people to make this mission possible and successful. But just as importantly, together we made it a joyful one. Rockets, spacecraft and space stations may be extraordinary pieces of technology, but spaceflight is, above all, a human adventure. And it is so much better when that adventure is filled with kindness, positivity and good vibes!
Many thanks as well to the French Air and Space Force for bringing me to Cologne. My 18 years of service taught me so much and played an important part in the journey that led me to become an astronaut. The moment I stepped aboard the plane, I felt at home, surrounded by family, my aviator brothers and sisters.
And now, first things first: getting my “Earth legs” and “Earth balance” back! 🌍

De retour sur Terre et de retour chez moi en Europe, accueillie par tant de personnes ici à Cologne. Quel retour ! 🫶 Merci à toutes celles et ceux qui étaient là, mais aussi à vous tous qui avez aimé et partagé mes publications tout au long de la mission. Vous avez contribué à mettre en lumière les vols habités et tout ce qu’ils peuvent apporter à la vie sur Terre.
La réussite de cette mission a été rendue possible par le travail et l’implication d’innombrables personnes. Mais tout aussi important : ensemble, nous en avons fait une aventure joyeuse. Les lanceurs, les capsules et les stations spatiales sont d’incroyables exemples de technologie, mais le vol spatial est avant tout une aventure humaine. Et avec de la bienveillance, de la positivité et des good vibes, l’aventure n’en est que plus belle !
Un grand merci également à l’@Armee_de_lair pour m’avoir ramenée à Cologne. Mes 18 années de service m’ont énormément appris et ont joué un rôle important dans le parcours qui m’a menée jusqu’au métier d’astronaute. Dès que je suis montée à bord de l’avion, je me suis sentie chez moi, entourée de ma famille – mes frères et sœurs aviateurs.
Et maintenant, une priorité : retrouver mes jambes et mon équilibre de Terrienne… 🌍

in honor of margaret hamilton, i’m posting this iconic image of her standing next to the printed apollo flight software that she and her team developed that helped take humans to the moon.
rest in peace to an incredible inspiration for women in the space industry.

We’ve lost an icon. Margaret Hamilton, a computer science pioneer best known for her work at MIT leading development of the flight software for the Apollo missions to the moon, has died at 90. Read about her legacy via MIT News: news.mit.edu/2026/margaret-h…

Your kid wants a drone.
DJI Mini 4K: $299. It films in 4K. It weighs under 249 grams. It comes with a remote.
Flix is the other kind. An ESP32, four motors, a 3D-printed frame. 2.1k stars. The flight code is under 2,000 lines. Short enough to read in an afternoon.
The sensor reads the tilt. The code levels the motors. You steer.
A phone can fly it over Wi-Fi. So can a USB gamepad. So can a normal remote. No app store account.
Gazebo runs the same Arduino code on screen before you arm the real one. Break the plastic, print another. The frame files are STL and STEP, in the repo.
There is a Python library for scripted flights. A wireless command line. A flight-control textbook, still being written. Position hold is on the list. It is not done.
One honest note. This is not a DJI. No camera. No GPS. A crash can break more than the frame. The author says it may not fly, and is not responsible for injury.
If you want the video, buy the Mini 4K. If you want to read how a drone stays in the air, build a Flix.

which board should you actually start with?
Arduino vs ESP32 vs Raspberry Pi
4 months into robotics as a hobby, here's what i'd tell myself on day one:
1. start with arduino
use it when you're learning:
- motors
- servos
- sensors
- basic circuits
atmega328p, 16 mhz, 2 kb of ram, and 5v logic so most hobby parts plug straight in
when your code runs, nothing interrupts it, and that makes timing easy to reason about
best place to learn the fundamentals without debugging an operating system at the same time
you outgrow it the day you add wifi or a camera
2. move to esp32
use it when you want:
- wifi
- bluetooth
- wireless control
- anything that reports back to your phone
dual core at 240 mhz, 520 kb ram, radios on the chip, around $5 a board
more connectivity and still hands on, so you keep writing the same kind of code
two things that cost me a weekend each:
3.3v logic, so your 5v sensors need a level shifter or they read garbage
and on the original esp32 the adc2 pins stop reading the moment wifi turns on
3. go for raspberry pi
use it when your robot needs:
- computer vision
- ai and ml
- ros 2
- heavy processing
now you're running a computer inside your robot, with all of the upside and all of the cost
linux decides when your code runs, so pwm timing jitters and servos twitch
and pulling the power without a shutdown corrupts the sd card, which i learned twice
also worth knowing, raspberry makes a real microcontroller too, the pico, about $4
so the quick version:
never wired anything before -> arduino
want wifi and the best price -> esp32
need vision or a camera -> raspberry pi
and yes, you can use more than one
arduino -> control
esp32 -> connect
raspberry pi -> compute
that combination is what took me 4 months to understand
the pi is the brain and the microcontroller is the spine, and a real robot wants both
also, if you want to learn robotics engineering for 6 months, read the article below:

Tous mes sens me disent émotion.
Et pourtant, rien n’existe.
Que vaut un ressenti réel face à une création synthétique ?
On le dénigre, on l’accepte ?
Ce ressenti vaut-il moins que celui généré dans la vraie vie ?

Last month, we refurbished 10 tennis courts in Crotona Park — the only public tennis courts in the Bronx with lights for night play.
We stopped by recently to see how things were going.
Thank you to @NYJTL, @usta and @yonex_tennis for helping us deliver high-quality public spaces that New Yorkers deserve.

Tomorrow, 🇫🇷 President @EmmanuelMacron will attend the ceremonial opening of the Bayeux Tapestry exhibition at the @BritishMuseum, marking an exceptional moment made possible by the historic loan of the Tapestry from France to the United Kingdom. 🇫🇷🇬🇧
As President Emmanuel Macron stated in July: « The tapestry recounts the epic story of William the Conqueror in 1066, an era when rivalry and war shaped our two peoples’ destinies. Since with this defining moment, our shared story within Europe has been that of the Entente Cordiale, of a shared commitment to Europe’s freedom, of the alliance between Churchill and de Gaulle, of great industrial and scientific endeavours, and of unparalleled human, intellectual and artistic ties. »

The King used part of his speech at the opening of the Bayeux Tapestry exhibition to address the French president... in French.
After welcoming Emmanuel Macron and his wife he said he hoped they had admired the tapestry, presented in the UK for the first time.
