Hardware looks scary until you break it down into small steps. So I built an app that takes you through Arduino one circuit at a time.
Made with Opus 5.5
learn-arduino-red.vercel.app
Two important changes to timeline recommendations:
- New AI/SI ranking model that predicts probable time spent much better
- Retrieval model trained to surface posts people read all the way through
User active seconds is growing exponentially and hitting all-time highs almost every day:
kid-me would have lost it over this.
Turns out grown-ups can finally make the office a tiny arcade 🏁

Our team built a playable 3D Wizard Chess game from scratch with Gemini 4 Argon using Google Antigravity in the Gemini app for Mac.
Coordinate a multi-agent Blender workflow to model, design, and deliver fluid, real-time animations so you go straight from idea to play.

Love this! If I had kids, I’d love to teach them this way.
I’ve been exploring learning through play too! A Claude skill for making hand-drawn, interactive everyday objects. Here’s my little washing machine :)

This is the new Tesla Roadster's fan and suction system, which the company filed a patent for in April 2025.
Sides skirts and front and rear skirts deploy under the battery pack, sucking the car down at ~2G. Because the skirts can move, they have some compliance, so they can deal with road bumps, road debris, etc. As the speed of the Roadster increases, the front and rear skirts retract to allow for air-flow (venturi effect) under the vehicle.
Tesla: "Our multi-mode fan and ground sealing system acts as a downforce generator, pulling air out from beneath the vehicle. This provides enough suction to hold the vehicle upside down, even when stationary. Powered fans and active wings maximize traction and cornering speeds in all conditions, achieving massive downforce at zero speed."
In their patent, Tesla said: "In the first mode, a complete set of skirts creates a fully sealed bounded region under the vehicle with central fans generating maximum downforce at low speeds on smooth surfaces. In the second mode, a subset of skirts (primarily side skirts) modifies the bounded region while all fans operate to provide downforce in dynamic driving conditions with uneven surfaces. The system includes a control mechanism to selectively deploy skirts and operate fans based on driving conditions, optimizing between maximum downforce at low speeds and improved performance over varying terrain at higher speeds."

I’ve never seen a product unveil come close to what Tesla pulled off with the new Roadster last night.
Elon was right.
It was the greatest product unveil we’ve ever witnessed.
Nine years of anticipation, and somehow Tesla delivered something even crazier than we imagined.
I was there in person, and I still can’t believe what I saw.
Nothing comes close.

Plus up your furniture with 3D-printed accessories using Gemini 4 Argon.
Upload a pic with rough measurements, and use Canvas in Gemini to build an interactive 3D CAD studio where you can explore styles, tweak live sliders, and export printable STLs to upgrade your space.

Holy shit y’all are not ready for tonight’s Tesla Roadster demonstration.
There is a massive ramp 😂

Two years ago today, SpaceX made history with the first Super Heavy booster catch. On the very first attempt.
Still one of the most incredible moments in spaceflight.
Try Grok @Bot
You can now use Grok @Bot in a Tesla Cybercab.
You just sign into Grok once, and your Bots will be available on all future rides, and automatically logged out when you exit the vehicle to maintain privacy.
I tried it tonight by adding laundry detergent to my Amazon cart. It can also send emails, place your coffee order, manage your calendar, finances, or other tasks using just your voice in the robotaxi.
On your next ride, you’ll automatically be signed in to all the apps you previously logged into as soon as you enter the vehicle.

This is the most exciting time at NASA since the Kennedy era.
@POTUS has given us the mission: return to the Moon, build the Moon Base, pioneer nuclear spaceflight, advance extraordinary science, and win the new space race.
It was great to see so many of those builders, scientists, and technologists recognized at the Golden Age of Science summit this week.
The President recognizes that American leadership requires taking on the big, bold endeavors that define American exceptionalism and empower the people with the talent and determination to turn those ambitious objectives into reality.

Anthropic’s Opus 5.5 Fast Mode is significantly more cost-efficient than OpenAI’s Sol 6.1 Ultrafast.
At roughly the same speed (280–300 tokens/s), Anthropic charges 33% less across input, output, and caching.
That’s 50% more tokens per dollar for nearly identical throughput.
Let that sink in.
