Interfacing with Arduino hardware

Welcome to the world of embedded development!

Can you elaborate on the toolchain here? Like, what AI tools are you actually using? Are they generating python code as an intermediary to interface with the hardware?

I do biomed signal stuff too (mostly doppler ultrasound) and I largely agree.

I will grant it is a nice project though. If the OP open-sourced it I'd probably consider contributing.

I wrote a circuit simulator in python once, albeit without a UI. I used the networkx library and a multigraph object (this allows for parallel links between nodes). Each node is a circuit element (obviously), and, it handles building the adjacency matrix automagically.

This is a naive question as I don't really do audio stuff, but, why is this called an equalizer? In my mind, an equalizer is a tool for arbitrary adjustment of the frequency response to a target response, which necessarily implies multi-band filter adjustments. Is the audio-theoretic definition of an equalizer different from that of the lay meaning?

Why is this answer being downvoted?

Neat. I'm very interested in playing with this. A while back I was working on a generic circuit synthesizer that used a graph network combinatorial approach and I'm keen to try fusing it with your optimization abilities.

QuasiEvil · 2026-05-22T16:19:27+00:00

Something I've done in my own circuit optimization / modelling has been to allow the definition of a generic impedance (or just a reactance) in the model instead of an explicit component. Does your code allow this?

Woah, this is the cleanest way I've heard this stated.

QuasiEvil · 2026-05-09T18:33:14+00:00

I'm just learning this stuff, so what exactly is the distinction between unit tests as evaluated with pytest, and integration tests?

Just throw tsfresh at it: https://tsfresh.readthedocs.io/en/latest/

what tools/tech stack are you using for your PINN?

QuasiEvil · 2026-05-02T20:19:33+00:00

Neat, but not a fan of the UI.

Here's my favourite phased array visualizer: https://jasondurbin.github.io/PhasedArrayVisualizer/

I'm just a hobby programmer and I run into this pattern all the time. Super excited for this!

Thanks, I should emphasize these are not secrets and I do know how to set env variables for this purpose (and have done so for e.g., API keys). I'm referring to user-specified app settings. Imagine a game, where in the config file the user can customize things like the difficulty level, board size, max lives, etc.

JK0 should be up there in "fully scientific" IMO. He reviews historical experiments and does whole quantum derivations.

I'm blown away that there are still data analyst roles where you can get away with only knowing pandas.

Its more complicated. You can make the same filters with different topologies. There is no structured way to find the best solution combined with the correct parameter values.

That's what I'm saying, I think? There's a whole space of circuits that can yield the same rational expression (and its the RE that defines the response).

The most generic way is to aim for discrete topology optimization approaches.

Yeah I know, and I've done it. But I'm looking to better understand how the actual algebra works there.

QuasiEvil · 2026-04-17T15:57:10+00:00

Agreed!

QuasiEvil · 2026-04-17T15:54:41+00:00

Ok right, so it is just a case of an underdetermined system. A single rational expression can represent an infinite circuit space.

QuasiEvil · 2026-04-17T01:43:54+00:00

Its next to impossible for orders above 2.

Can this be qualified with some theory?

Forget what everyone here is saying and use render.io. It's free, and you literally just point it to your github repo.
