Building a 3D printer at 12 is cool… until you come home 10 years later and find it buried under 6 inches of dust Throwback to my first love

Cool to see that ATP synthase uses a compliant mechanism to add phosphate to ADP!

Someone just built a Claude Code for electronics. It's called Blueprint. Type what you want to build and it generates wiring diagrams, bills of materials, and step-by-step assembly guides for your Arduino or Raspberry Pi project. 100% Free.

Blinking Eye I reused the AI board I have built and pointed it at one small task: a smooth open/close height animation + movie reference. That’s it. No new setup. No extra complexity. Just my AI software firm running a structured workflow with the tools I already made. More complex stuff coming soon 🧵

Everyone’s hyped about AI email assistants. I built something different. An orchestrator that spins up multiple Claude instances in the backend, each with a dedicated role (CTO, engineer, etc.) working together to tackle complex tasks autonomously. You interact with your AI “software firm” live via dashboard or Slack. You’re the board member. They execute. Early days, but I have been using this for the last couple of weeks! More updates coming soon. 🧵

We've uploaded a fruit fly. We took the @FlyWireNews connectome of the fruit fly brain, applied a simple neuron model (@Philip_Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action. A few things I want to say about what this means and where we're going at @eonsys. 🧵

AI is adapting to us faster than we are adapting to it.

Random thought from everyday housework 👇 For years, one of my parents’ wardrobe doors wouldn’t close. Heavy solid wood + time = the door sagged, rubbed the frame, and made that awful squeak. Fix? “Just lift the hinges a bit.” Reality? A woodworker quoted $200+ for what felt like a 10-minute issue. So my dad and I said: nope. We measured the hinge mount, recreated it in CAD, generated toolpaths, and machined a new part on the DIY CNC we built when I was a kid… after ~4 failed iterations 😅💀 (and lots of travelling downstairs to the ‘lab’) It worked. But… why was this so hard? Should small home fixes be this complicated in 2025? What would it look like if you could describe the problem to a laptop and it designed the part automatically? And how do we make that accessible to people who don’t know CAD/CAM at all?

@emm0sh All this GD&T and no assembly? We need a sequel

day three of adding complexity to this drawing per Y14.5 until ASME tells me to stop

@theonlyAyo @HanomiAI Thanks Ayo! A lot is coming up in 2026

@_marco_masc hey marco, I think @HanomiAI is sleek. would love to connect. Your DMs are closed

Back in the lab from my childhood ⚙️

RIP to this 1mm drill bit (2025-2025) Cause of death: Overconfidence in toolpath splitting You will be remembered... as a cautionary tale 🪦

People who’ve never set foot in a factory will never understand. I watched this three times.

Dudes will see these machines and say “Hell yeah”

When design and functionality ghost each other all the way to production

we kicked off with portfolio founders @tdoggyholhol @_marco_masc and simone sharing their advice whilst overlooking an insane bay bridge view

@fabworks_guy Nice modularity! But those screws had better be brave enough for some shear load

1/16” laser cut aluminum tubes + these inserts gives you 80/20 style modularity for a fraction of the weight.

@aphysicist Fair point, tho a 5min design mistake can turn into massive manufacturing problems later

The amount of time to design anything in hardware compared to the time to manufacture it rounds down to zero. Design is overrated, manufacturing is underrated.

'time flies, so don’t blink twice'

@mattfreed Crossed out dims also made it through the review!

- Ask for engineering drawing - receive back literal drawing COMEONGUYS

@TomSmithMFG Is a base raft also important for this nozzle size?

Layering the cake. 🍰 before it hits the 5 axis for the precision
