I'm beyond excited to share that #Teardown2026 will be happening 24-26th July.

We're in a cool new space too: the Jupiter on Burnside. Our 60s mall era is dead, long live our 60s motel era.

I'll miss the mall but it'll be nice to run an event somewhere with furniture and internet.

Ticket sales, calls for participation + volunteers, and general info on the @crowdsupply website: https://www.crowdsupply.com/teardown/portland-2026

did you know that you can find free Cortex M0 development boards at the side of the road? folks call them disposable vapes but they're hackable, and i've reverse engineered a bunch of them! see https://github.com/schlae/VapeRE/

Do you have a J-Link compact and wonder why it only works with _some_ USB-C cables? I looked into why that is 🤬

Spent waaaaay too long trying to figure out why my board's SPI bus on GP6-GP9 wasn't working 🤦‍♂️

"Even if Wikipedia’s content was biased (it isn’t), even if every editor was actively trying to push an anti-Israel narrative (they aren’t), that would still be protected by the First Amendment. The government doesn’t get to threaten organizations over their editorial choices, no matter how much certain prosecutors or publications might dislike those choices."

Government Actually Threatens Wikipedia’s Editorial Freedom; Self-Proclaimed Free Speech Warriors Suddenly Have Other Plans

When Trump officials want to censor speech, they don’t quite say “we want to censor speech” (after all, they pretend to be the party that “brought free speech back.”) Instead, the…

Looking forward to the full-throated condemnation of this letter by those who accused the Biden administration of pressuring social media firms to moderate COVID-19 and election fraud misinfo! Any second now...

Have you ever wanted to debug your microcontroller over USB-C?

(I’m talking JTAG/SWD, not just USB!) If you already have a USB-C connector, there’s no need to have an additional connector to program!

This started as a twitter thread years ago, but I've cleaned it up, and added tons of new information. Let me know what you think!

SWD to USBC

Have you ever wanted to debug your microcontroller over USB-C? (I’m talking JTAG/SWD, not just USB!) If you already have a USB-C connector, there’s no need to have an additional connector to program! (or Tag-Connect pads, which are super nice, but take up additional space) I’ll explain how I did it below. NOTE: Much of this was originally a few Twitter threads back in 2022. I’m adding a lot of the original content from then, but with many updates, fixes, updated designs, and examples.
