Last night we hosted the 138th SF Hardware Meetup at Flux HQ for TECH WEEK by a16z 🔧

A room full of people building real hardware, five great talks, an open mic full of pitches, and a birthday cake for Matthias.

Thank you to Michael Raspuzzi for organizing it, to Nate Padgett for being emcee, to Kimberlee Hayashi (Mantle), Saba Khalilnaji (Almond Robotics) and Francisco Gimenez (8VC) for speaking, and to everyone who showed up.

More events to come!

Flux just turned 7.

Seven years of taking the hard out of hardware, and it still feels like the beginning.

Thank you to everyone building with us.

If your board works, the last step is to give it a body. 📦

And what's a better way to do it than using the same tool you already designed your PCB with

Flux can now design a 3D-printable enclosure around your actual board.

Most of hardware engineering is holding something small and looking at it very closely.

That's the step no tool has ever removed. It's also the step that tells you whether everything upstream of it was right.

Last night we hosted an enclosure design workshop at the Flux office, on the same day we launched the feature. 🚀

Electrical engineers who’ve designed boards for years sat next to founders who are mid-prototype on their next product. All of them working on turning a board into a product.

Thank you to everyone who came out. More workshops are coming, so if you’re building hardware in SF, come build with us.

For us, a circuit board was never the finish line.

Starting today, Flux can generate an enclosure for your PCB.

Flux is bringing ideas out of people’s heads and into their hands. It’s time to enter your hardware era.

Most PCBs are rectangles because nothing is stopping them being rectangles.

This one had to be round. It goes inside the cup of a pair of headphones, and the frame decides the outline before the electronics get a say.

Aaron is starting a hardware company, and modded headphones are where he's starting — the idea that a pair of headphones can be something you look at, not just something you listen through. Episode 1 is the circuit board.

He described the project in Flux and it went to work: the ICs, the audio jacks, the connector for the LiPo battery, the toggle switch, the pull-up resistors and decoupling caps that keep the thing behaving. Then it changed the board outline to a circle and arranged the components inside it.

He still chooses the parts and approves the layout. What he skipped is the week of learning a legacy tool well enough to draw it by hand.

Next: verify the design, export the Gerbers, order the board.

The hardest part of hiring for Flux is explaining the job.

You're not building a CAD tool. You're not building a chatbot. You're building the future of hardware design.

Roles are in the comments.

A full drone motor controller, block by block. 🛩️

Open source. Fork it and spin it up.

Comment SPIN and the design lands in your DMs.
