Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Going in circles without a real-time clock
Unfortunately a Raspberry Pi is a bit ill suited for production environments. Id recommend an RTC module. Otherwise this might be helpful: https://github.com/hcfman/sbts-aru

Running a Raspberry Pi with a read-only root filesystem
If you install my sbts-aru project
https://github.com/hcfman/sbts-aru
It will shrink your partitions, add news and install one of these and set up a sub micro second system clock and an audio recorder suitable for sound localization with a single install command.

2024-03-01 listening in on the neighborhood
I recommend primo EM272 microphone capsules for use with https://github.com/hcfman/sbts-aru. They are high quality, very sensitive with high signal to noise ratio, lauded for nature recording use cases. They can be bought assembled for around 65 euros in the Netherlands. However these capsules are often found in much more expensive equipment.

Considerations for a long-running Raspberry Pi
My sound localizing Raspberry Pi installs a resilient base system as part of its install.
https://github.com/hcfman/sbts-aru
https://hackaday.com/2023/12/30/localizing-fireworks-launche...
With one command it for all Pi’s for both Raspbian and bookworm it:
* Shrinks the file system (Gee, how does it do that with just one disk ? ;-) )

Colorado wolf reintroduction to move forward as ranchers' legal effort fails
I have a sound localization project that can help with that
https://github.com/hcfman/sbts-aru
You need to be able to hear the sound from three or more recorders. And normally localization is better within the polygon of microphones but there’s an area of better localizability extending outside of a vertex.

Acoustic Location and Sound Mirrors
Interesting history!
And while we are in the subject of sound localizing may I take the liberty of introducing my new raspberry pi sound localizing audio recorder.
https://github.com/hcfman/sbts-aru
It installs with one command on all Raspberry Pi versions and synchronizes the system time to less than 1 microsecond of error with a cheap GPS.
With three of these I’ve been able to sound localize the explosions from illegal fireworks to a specific car park from more than 3km away with lots of houses in between.
When I got to the car park I could smell the sulphur from the fireworks.
This will even run on a Raspberry Pi zero running of a battery with a 6 euro neo 7m gps and a 6 euro usb mic.

AI tool helps ecologists monitor rare birds through their songs
Very nice tool!
So grab a spare Raspberry Pi, a GPS, a cheap USB sound card and a mic and get recording with this Pi based Acoustic Recording Unit
https://github.com/hcfman/sbts-aru
And while you are at it, install 3x or more and localize where the birds are.

Ask HN: Comment here about whatever you're passionate about at the moment
Sound localizing. I was intensely passionate about it when I saw the possibility to do it well on a Raspberry Pi. There were quite a few more problems than so expected which is why it took five months (of weekends) to complete it well.
But I’m super happy with the result and have a bunch of geeks with recording nodes setup a long distance apart. Localizing large explosions show that it’s possible to localize to a carpets even when some of the nodes are almost 5 away.
For those interested, here is the project:

> It’s haven’t bought any Modular’s yet but I’m really looking forward to getting into other on the new year.

The former is libre and gratis, runs as a standalone or plugin and in the browser!! and is based on the latter.
Ther former has a libre and gratis standalone version, the plugin version is non-gratis.

Ask HN: Whats the modern day equivalent of 80s computer for kids to explore?
A music synthesizer. It's a pathway to learning electronics, music, and the nature of sound. There are cheap kits, cheap synths, lots of kinds of synths, and there are much more complicated and expensive systems you can grow into. You can get software synths also, VCV Rack is a free though complex one:
https://vcvrack.com/
However I'd recommend an inexpensive hardware one with real knobs you can turn, like one of the Korg Volca series:
https://www.korg-volca.com/en/
Recording the sounds can lead into exploring all the concepts and gear involved in recording and mixing music. It's not mutually exclusive with doing other things also, you can play with both synths and computers and being involved with something artistic can add dimensions to and an escape from the nature of classwork/work.
Some other suggestions: gardening, high voltage electronics (with lots of supervision), electronics, photography, movie making, ham radio (gnu radio), show lighting systems (there's more than disco lights, robotics is involved), robotics, acoustic instruments (guitar, piano, flute, drums), sensors (you don't necessarily have to know electronics, get a data logger with built in sensors), weather monitoring/forecasting, hydraulic systems (with supervision), wood working, metal working, 3D printing, bird watching, painting, minibikes/small engines.

I love synthesizers, but I suck at synthesis and sound design?
What really opened my eyes was the Nord Micromodular; it taught me what I just described. It showed me how limited other synths were - but that limitation was a trade-off because it's much faster to make something on a fixed-structure synth than on a modular, in most cases. Nowadays, you can use https://vcvrack.com/ instead of a small limited box that needs Windows 98 to run the editor on.

Long time Cubase user who is leaving a more traditional electronic workflow to modular hardware... Bitwig seems to be the DAW more for this style possibly? Any opinions first hand?
Also I would suggest the paid version of VCV rack which works as a VST too ( the free version is just stand alone ) Expecially when experimenting with modular ( believe me, it can save you a fortune whilst you learn what different modules do ) I would also recommend Omri Cohens Youtube channel for learning this too.
What are some alternatives?
