Ask HN: What is the most impactful thing you've ever built?
The Arduino MIDI Library [1]. Back in 2009, I learned C++ to build it and control my guitar effects pedals with custom electronics as part of my engineering degree.

Help to made a piano midi and cv controller for eurorack (see my comment below).
Your project can be broken up into a number of subprojects. For keyscanning you don't need additional hardware, just the pins from the ribbon cables going to the arduino's digital pins and ground. Since the keys are just switches (two per key, the time difference between the two switches closing giving the source of velocity), you could start with some examples from the Arduino MIDI library (https://github.com/FortySevenEffects/arduino_midi_library). To test MIDI sending you don't even need to start from the keybed just yet, and if you do, you can start with a single key. Once you've got that part figured out end to end (key press/release generates note on/off events) you can work on iterating through the matrix, CC controls etc. MIDI out can be done in different ways. With a 5 pin DIN plug you'd just need two 220 ohm resistors.

What frequency should a timer interrupt be to receive MIDI messages?
On an Arduino compatible platform the configuration of the baud rate at the bare metal layer is taken care of by the library when you call its begin() method. Looking at the example code included with the library it appears that there are no timer interrupts or anything like that required of you in order to use it. Another thing that jumps out is that the call to read() returns a non-zero value if anything has been received that you should use to predicate whether any further attention needs to be spent on it by your code. You may know this but it wasn't apparent from the loop() { MIDI.read\`() }` example that you gave above.

FastLED run Parallel & Simultan multiple Led Strips
As i have started to combine this with Midi Implementation from FourtySevenEffects lib, i only have done a quick test with two/three strips and did discover follwing issue(s):
-
Reading MIDI stream
Using a library for the midi shield you can register two functions as callbacks. One callback for NoteOn(...) messages and one for NoteOff(...) messages. But thre is much more. In the end the source of truth should always be the docs for the library itself.

Looking for the smallest possible MIDI hardware (end purpose: momentary pitch shifting)
Here’s a library that might work.

Ask HN: How did you earn your first $100 and first $1k online?
First $100: Thirty copies sold of Video Hub App
First $1,000: Three hundred copies sold of my Video Hub App
https://videohubapp.com/
Though I do donate $3.50 of every sale to a cost-effective charity so in theory I made no money for a while until I bumped the price to $5 / copy.

Jellyfin: The Free Software Media System
semi-on-topic: I created Video Hub App that is like YouTube for local files: shows you a gallery with scrub-able (preview on hover) thumbnails. But does not work streaming videos to TV / tablet - only for local consumption. Hope someone finds it useful.

Generating Income from Open Source
I created Video Hub App which is MIT License
https://github.com/whyboris/Video-Hub-App
I also sell it for $5 and have sold just over 5,000 copies last month (5 years old app). Importantly, $3.50 of every purchase goes to a cost-effective charity, GiveWell recommended Against Malaria Foundation (see website for details).

Python GUIs
"The problem" might be that people in this thread and others get frustrated because others have different goals than them.
Of course Electron is overkill for a single-button application. But Visual Basic is absolutely going to be a headache if you want a custom GUI.
Pick the tool that's right for the job!
I build this with Electron: https://videohubapp.com/

Ask HN: Most interesting tech you built for just yourself?
Simplest File Renamer - https://www.yboris.dev/renamer & https://github.com/whyboris/Simplest-File-Renamer
I wanted to be able to quickly rename files with my text editor (using keyboard commands), so this lets me do it. Plus I share the app online for free.
Video Hub App - https://videohubapp.com/ & https://github.com/whyboris/Video-Hub-App
I started it just for myself, but it ended up so good I spent several more years improving it as people kept buying it (up to almost 5,000 purchases since I started).
Also wrote a couple of dev tools for myself (sharing via NPM too) - https://www.yboris.dev/

I've been data hoarding for 25 years. I have a bajillion hobbies. It's hard to stay organized.
I created Video Hub App: https://videohubapp.com/ - it shows screenshots from videos as you scrub/hover across the thumbnail.

FFmpeg 6.0
I've been so frustrated that FFprobe functionality is not part of FFmpeg.
My app extracts screenshots from videos to create a beautiful gallery of videos. But even though I include FFmpeg already, I need a 50mb FFprobe executable to be bundled with my app just so that I can determine the width, height, duration, and fps of a video file! What is it that FFprobe does that FFmpeg couldn't do with a few extra pieces of exposed API?

Those making $500/month on side projects in 2023 – Show and tell
Created Video Hub App (that will be 5 years old next month). I sell it for $5 and $3.50 of each purchase goes to the cost-effective charity Against Malaria Foundation (See GiveWell.org for details).
It was averaging around 100 purchases per month, though it's lower over the last year as I've not had time to release new updates (moving to another state is challenging).
https://videohubapp.com/ - Think of it like YouTube for videos on your computer. Browse, search, and organize your videos

Ask HN: What is the most impactful thing you've ever built?
Built Video Hub App that almost 5,000 people have purchased. I was a math teacher, became a web dev 6 years ago, built this 5 years ago. Most proceeds go to charity. Very minor by comparison to others, but I'm just starting out ;)
https://videohubapp.com/ && https://github.com/whyboris/Video-Hub-App
What I did that is most impactful is that I've been giving at least 10% of my income to cost-effective charities for over 10 years now (see Giving What We Can - thousands of others do the same). This amounts to almost $100,000 given to charity which translates to thousands of people protected from malaria for many years of their lives.

Ask HN: What's a good business model for selling standalone software
My personal model for my commercial software: charityware - require a payment but made most proceeds go to my favorite (cost-effective) charity.
I'm getting about 100 purchases ($500/month, donating $350 of that) with my Video Hub App - https://videohubapp.com/ - which is also open source - https://github.com/whyboris/Video-Hub-App
I wrote about charityware a few years ago: https://medium.com/@whyboris/charityware-doing-good-with-pro...
