I'm building a collator robot [0] to help me pack items I sell for building your own open source split-flap mechanical display [1].
I get custom character flaps printed and die-cut in bulk and then sell them in smaller sets. A full set of flaps for one module has 52 distinct designs (letters, numbers, symbols, etc) and I get them from the manufacturer grouped by design, so they need to be collated to sell as packs of 52 with 1 of each design.
My WIP robot will take a stack of one design and distribute them to a bunch of cubbies, then I'll swap in the next design, and so on, so each cubby ends up with a full set.
It's based on a cheap ~$110 CNC gantry frame from AliExpress and a ~$35 BTT SKR Pico 3d printer main board running GrblHAL. To detect whether the flaps feed successfully I use a visible light break-beam sensor (the typical IR sensors don't work because the PVC flaps happen to be IR transparent!) which acts as the "z probe" - the flap is fed via a G38.3 probe action which returns whether the probe was successful or not, and the "z" coordinate it was first detected.
I have a python script running on a computer to send the gcode to the machine.

Please keep up the great work on this! I love this split flap project. It's gotten me into electronics. I haven't had the chance to build it out yet, but I want to put together a sign as a project.

Your move, Aaron Rodgers.

John Rawls: A theory of justice. It's attempt to derive a theory of justice (obv.) using methods borrowed from analytic philosophy was hugely influential. Whether you agree with Rawls' conclusions or not it's a brilliant, meticulously argued book, albeit incredibly dense.
I got a minor in philosophy in college and we read this book for one of my classes. At the time it was one of the hardest books I'd ever read. But someday I'll go back and reread it.

[Addendum] …or, generally, any book about back-of-the-envelope calculations (or Fermi estimates). I heard there are some great ones.
I'd be interested in recommendations about books like this.

Add whatever site is sucking up your time to /etc/hosts.
Forgive my ignorance, but what does this do? I'm interested. Would I just add Twitter/Reddit/whatever to the file with an IP of 0.0.0.0 so it throws an error or something?

"Eschew flamebait. Avoid unrelated controversies and generic tangents."
My comment doesn't meet any of this criteria. The original article was about a Chinese company's unauthorized fork of OBS. It's semantics whether or not you consider an "unauthorized fork" as stealing, but I certainly do.
So it's neither unrelated or a generic tangent, as it relates to intellectual property theft. It's beyond question both that China as a country is known for stealing intellectual property, and that Chinese companies work closely with the CCP.
In the introduction of The Wires Of War by Jacob Helberg, he cites a statistic that estimates that "Chinese theft of intellectual property costs Americans anywhere from $225 billion to $600 Billion every year..."

China stealing intellectual property? If only we could have seen this coming!

The Impostor's Handbook https://bigmachine.io/products/the-imposters-handbook/ has been helpful for me. Been using it to supplement learning from a coding bootcamp.
