This is the second version of my mini AI wildlife monitor, for edge-compute based species identification.
The software and STL files are all available for download!

building a lego castle case for raspberry pi 5 and about 70% of the way there just waiting on more pieces to arrive. it has openings for ports, and interior is designed to hold pi in place without rattling around.

the case opens from the large port wall it’s supposed to open like a flag on a pole situation but I think I need to replace some regular bricks for round bricks to
make the open and close swivel “mechanism” work smoothly.

LIVI is an open-source Android Auto and CarPlay headunit application. It works on Linux, macOS and Windows, but the most exciting target is the Raspberry Pi where it makes a tiny in-car infotainment system possible. Released as AppImage, deb, DMG and Windows installer, no manual build required. On the Pi the only hard requirement is Raspberry Pi OS Trixie, because the UI uses WebGL2 which depends on the Mesa stack that ships with Trixie.

Mainly tested on Pi5 / CM5. Power on -> stream in less than 22s.

What it does:

- Wired Android Auto over USB (AOAP)
- Wireless Android Auto over Wi-Fi + Bluetooth pairing
- Switch between wired and wireless on the fly
- Multi-touch input, keybindings, navigation, media metadata, hands-free audio
- Turn-by-turn navigation data integration
- Instrument cluster streaming with safe-area support
- Reverse camera
- CarPlay supported via carlinkit dongle. Native CarPlay is on the roadmap (requires an MFi authentication coprocessor)
- Forwards sensor data to the phone (GNSS, speed, EV SoC, etc.)
- Multiscreen support with flexible routing
- Embedded GStreamer

In the process of getting a reasonable offer for a Pi 5 + Nvme. I wanted to run some quick webserver deployment locally as a testing environment. However I had hoped this would be portable and require minimum network connections. No ethernet, no wifi, USB C power with data in 1 cable from my laptop.

15w power output from laptop will likely be fine as I'm not putting a lot of load on the pi.

SSH directly from USB C, how viable and reliable is it?

I found the post on USB gadget mode. But I have no way of testing it before I get the Pi.

yeah self promo ig - but thought of sharing anyway.

This is my first cyberdeck. I’ve been working on it for around a month. It features a Nuphy Air60 v2 kb, a Waveshare 11.9 display, Raspberry Pi 4 and a USB Hat powering the whole thing with two 18650 batteries. The interface is a customized tmux with a custom login screen. The case was designed in FreeCAD.

Hey :)

I'm building a privacy-first home security camera called the ROOT Observer, and today I've finished the second prototype, although it's the first one that is presentable. This is printed in PLA on a Bambu P2s, I'll soon try out SLA to see if that looks more professional.

The last few months I've spent building the open-source firmware and app to power this device. It enables end-to-end encryption, on device ML for event detection, encrypted push notifications, OTA updates, health monitoring and more.

The camera is a standalone device that connects to a dumb relay server that cannot decrypt the messages that are sent across. This way, it works right out of the box.

I'll soon (fingers-crossed) send out the first pre-production units to testers on the waitlist :)

...if you're mainly interested in the software stack and have a Raspberry Pi Zero 2, you can build your own ROOT-powered camera using this guide. The firmware is very optimized so that you can stream video and audio, record, run ML, transfer recordings etc. simultaneously without crossing max. ~60% CPU utilization.

Happy to answer any questions and feedback is more than welcome!

A few months ago I posted my Raspberry Pi “Thought Catcher”, a screenless device designed to let you record midnight ideas and tasks without opening a smartphone, helping to avoid screen time and infinite scrolling before sleep.

I’ve been quietly rebuilding the whole system since then.

The new version is much faster, smarter, and now has an 'AI Curator' mode that’s become my favourite feature!

When I capture an idea, the system goes off and finds 2-3 adjacent things: a designer, a movement, a concept; and leaves them sitting next to the idea by morning.

The thing I learned rebuilding it

Making the Pi faster wasn't just optimising it but to actually move the intelligence off it!

• Whisper still transcribes locally on the Pi
• Reasoning now runs on Groq's free tier (Llama 3.3 70B, under 1s per call)
• The Pi is doing exactly one thing- capturing.

The result

• captures are now ~3 seconds
• the fan stays silent
• no waiting around
• still just: press, speak and zzzzzzz...

Attached a rough walkthrough of the current version because a few of you were asking whether I was still working on this thing.

Original post for context: https://www.anshtrivedi.com/post/tc-01-a-bedside-thought-catcher-capturing-ideas-without-opening-your-phone

every new tab rolls a random rocket. save the ones you like and they'll come back. ~2×10⁴³ combinations, all deterministic from the hex palette.
rn it works on bash, zsh, powershell, and fish

lmk what you think!

* I added images of the project but Reddit has technical problems at the moment... So if you don't see images, revisit the post maybe later.

I shared this project here on the forum a few months ago, and I’ve now put together a full Instructables page with all the code, parts list, STL files, and some basic instructions. It’s not a step-by-step guide, but everything you need is there https://www.hackster.io/Seafox_C/iss-percise-indication-of-sewage-storage-65dba4

If this inspires you to spend hours and money on a completely unnecessary project… you’re welcome.

In Short:

The tank folows the tank on the ISS (International Space Station) in Realtime.I uses a Raspberrypi zero 2W a weight scale, OLED display, LED, 2 MOSFETS and two pumps.

I also made a YouTube video with some basic explanation what it does:

FAQ

Why?

Because I can.

So far I have run into some annoying issues. I am running Raspberry Pi OS Lite, and once I install OpenMediaVault, Ethernet does not work right away out of the box like it does on Raspberry Pi OS. Because of that, I have to connect a keyboard and monitor so I can run the OMV first aid tool and manually configure the network settings. I cannot SSH into it since there is no internet connection.

After I disconnect anything I used, like the keyboard or screen, it forgets all the Ethernet settings I just changed. It will not reconnect to the internet unless I plug everything back in exactly as it was when I saved the settings.

After accepting that situation, even though I would prefer not to, I kept a keyboard and monitor connected. Then the Pi password suddenly changed on its own. The password I had been using for the past three hours no longer works.

I did a clean reinstall of the SD card with Raspberry Pi OS and set everything up again, but this time the password does not work on first boot onto OMV (worked in pi os).

I really want OpenMediaVault to work, but I am also open to more stable alternatives. Any ideas?
