I've gone through this same workflow and had success all the way through DRC ruleset passing with JLCPCB-based settings, ordering, fab, and use. Board was ordered with PCBA (they did assembly of the stock components) and I did SMD for

I became significantly better at electronics soldering by learning to do glasswork (stain glass fixturing, etc). It wasn't intentional and it isn't even the same solder chemistry, but having to do broad asthetics on large pieces m

Good old fashioned machine learning (GOFML?) Using mixes of different sensor data from industrial 3d printing processes to production quality. Not as fashionable as LLMs at the moment but there's new innovations to make in the space, s

Yeah I had the same question. I suppose you could put the project+plan text into the commit message?

I worked on this about a decade ago, but just updated it in order to learn to use Gradio and HF as a platform. Enjoy!

I end up asking the same question when experimenting with tools like Cursor. When it can one-shot a small feature, it works like magic. When it struggles, and the context gets poisoned and I have to roll back commits and retry part of the w

Another reason why the idea of AI agents for science hasn't made much sense to me. Research is an extremely collaborative set of activities. How good would a researcher be who is very good at literature review, but never actually talks

Voynich is one of my favorite unsolved puzzles. This approach looks fascinating, so thanks for sharing your work here!

You and I have matching stories, unfortunately. I've made a point of sending my sons to public school for this reason. Now, of course this also means that I shopped for a district that aligned with my expectations. But would never want

This is still how the aeronautics portion of NASA operates. Though since it is the direct successor to NACA, I think its unsurprising.

In my area, every controls engineer says "we can just use a PID". 99% of the time it seems they're not wrong, despite control engineering being a pretty large area of research.

I'm thinking about what I've read on social media (twitter, reddit, etc) about the event. The posts getting the most engagement/traction are convinced this is larger than Chernobyl. However, relevant authorities do not seem t

I'm finding it difficult to find objective assessments of the impact of what has happened in East Palestine. It seems like there are interests in dismissing the impacts entirely, but there are others that seems to want to overstate the

I absolutely had this issue most of last year, but the Gmail spam filter seems to be catching things more effectively for me in the last two months.

My dad used to be a security guard at the Cleveland Museum of Art. What's funny is that often guests would ask him and the other guards about specific pieces or artists as if he was a subject matter expert (although he has always been

I think this is related to why I got into stain glass window making as a pandemic hobby. As everything I was working on felt ephemeral and physically disconnecting, it was refreshing to take on something both creative and tangible.

Congrats on launching. I'm not Christian, but this does remind me a bit of the Sefaria project, which aims to bring together a library of Jewish texts for scholarship, and has a great mobile app. This project also seems to have a deep

Great read! In comparison, I have to wonder why the "intelligence estimates" were so bad/severe over estimates.

I've come to internalize the Fourier transform as a type of sparse matrix algorithm. I.e. something that implements a particular matrix-vector product without requiring explicit construction of said matrix.
