fridays are for demos!

american airlines is by far the most consistent airline. they consistently bungle every flight I book with them.

on my run this morning I saw someone riding a converted electric bike, but it had been converted by removing the back wheel and replacing it with a Onewheel.

Part of a weekend project coming together: belt-driven linear actuator with a 28BYJ-48 stepper controlled by Zephyr firmware on a @nordicsemi.com nRF52840. Linear rail bases and carriage attachment designed from scratch in Onshape and printed on Bambu Lab A1 Mini.

I accidentally cut too far in on the corner of this rail / motor support base, but now I kind of like it.

not looking too bad.

cycloidal drives are so cool.

you know it’s gonna be a great weekend when it starts with a new set of machine screws being delivered.

small test print to evaluate printer accuracy on clearance holes.

I love this little baby linear rail.

Saw there was some space left on the @tinytapeout.com GF 26B shuttle that closes tomorrow, so I had to get a quick design in! Extremely simple hardware implementation of demosaicing using nearest neighbor interpolation, with pixel data being delivered over UART.

Lona and I went on a rescue mission for this little guy today.

“they expect one of us in the training data, brother”

this is exactly the kind of sass I'm looking for from my agents.

i did not expect to find this level of detail in the sony service manuals.

orange site? on a thursday?

american startups thinking they have creative company names don’t even know how far behind they are.

“It’s one Difference Engine, Babbage, how much could it cost?”

the favorite lock-free data structure of software engineers who also love The Office.

**JLink JTAG Access on the Pinecil** I've been doing more work on the Pinecil recently with Bouffalo Lab BL706 (SiFive E24 core complex) support landing upstream in Zephyr. I wrote a short post detailing how to use a JLink for JTAG access to the RISC-V debug unit. danielmangum.com/posts/jlink-...

every time I travel through the Minneapolis airport, I stop and pay my respects to the Panda Express, where I once found myself spending the night sleeping on one of its very uncomfortable benches.

If you're at the RISC-V summit in Minneapolis, @danielmangum.com's talk tomorrow is a can't miss!

Come to my talk at RISC-V Summit tomorrow to see me connect things to the internet that probably shouldn’t be connected to the internet.

my goodness minneapolis is an incredible city.

the number of wires will continue increasing until morale improves.

Looking forward to @linuxfoundation.org #OSSummit this week! I’ll be giving a fun talk at the @riscvinternational.bsky.social Mini Summit on Thursday on connecting the Pinecil soldering iron to the internet using Zephyr and @canonicalltd.bsky.social / @golioth.io. Reach out to you’d like to chat!

somehow I always find myself soldering with an hour or less before I need to leave for the airport.

transatlantic flights are the best time for some hardware hacking.

it’s race day!
