These look great. I wish they had existed way back when I did embedded work every day. What was the process like to create them? Did you design them from scratch, get them built to…

I’m curious, does the addition of wireless enable anything that wouldn’t be possible on RS485? Naively to me, it seems like it would add failure modes and hurt worst case performan…

Respectfully, no, not even a little bit. That’s normal everyday microcontrollers for you.

Worth noting that kobo devices are not locked down at all and run linux. They’re very easy to build for.

This looks interesting and I'm curious if anyone has more context for why it's on the frontpage today.

International airports as well.

It reads to me like encryption is handled one layer below this by NFS. I would naively assume this should be set up with external changes disallowed since it is capturing and repla…

Any recommendations on where to source BPA-free thermal paper? I've tried to source BPA free shipping labels in the US and found them unobtainable.

That sounds like this with inline dictionaries added unless I’ve misunderstood you.

I built something quite like this with epubs for another read it later service. There are lots of them!

I wonder if they’d be willing to sell it to the right group of folks. I’d love to have a community owned read it later service. Otherwise, we’re all on a never ending treadmill fro…

Same here. I get a massive amount of value out of writing things down at home and at work. I get comparably little value out of linking things together — beyond direct references a…

I’m surprised that they only ran the measurements ten times. Hard to trust any data in this post given it is certainly deficient.

This looks very cool! I see a lot of Python in the docs; is it usable in other languages?

This is unfortunately not emphasized with many breakout boards. It pays off to skim errata sections at the start of a project. All hardware has errata, and it ranges from incorrect…

There are industrial knitting machines, but they’re orders of magnitude more expensive, heavier, and tied to closed software ecosystems. They’re extremely capable, but they’re also…

Same, and I add one even more amorphous criteria, 'not directly next to noise pollution like an airport or highways.'

I have not observed this to be true. Ventilating enough to keep CO2 low means sub 20% winter humidity in multiple places I’ve lived.

Fewer people will walk when infrastructure prioritizes drivers and makes it uncomfortable and unsafe to walk. This isn’t the only option. Cars being built for pedestrian safety is …

You may also enjoy the Expeditionary Force series. Totally different story, but it has a similar vibe.

Someone built this! https://railforless.us

Linux probably boots faster fwiw. As a starting point, see this bench: https://www.daemonology.net/blog/2021-08-12-EC2-boot-time-be...
