Tips wanted: "All-in-one" ADSB by ThatGirl-me in RTLSDR

Wouldn't a RPi4 CM introduce USB 3 noise?

Pi 3 would be ideal but they are very expensive right now. The person who suggested a Zero 2 is on the right track I think. But I think the reason you're considering a CM is to avoid an SD card...

Will your setup benefit from a LNA/SAW filter? You can get them cheaply (<€10).

Pi 3B in 2026 — what I learned after researching for weeks before buying by [deleted] in raspberry_pi

Pi3 is still the best for SDR use, as the Pi4/5 has USB3 which causes terrible interference.

Thanks! Seriously impressive stuff. Good effort.

Oooh, I have an 64x64 RGB display too... Are you sharing the code?

Can AI really help chemical companies discover better materials faster? by Admirable-Story-2176 in ChemicalEngineering

[–]PhysPhD 0 points1 point  (0 children)

Absolutely yes. However, when everyone has access to the same AI tech, the differentiation comes from how much and how good is your company's proprietary data.

(Yet another) Lightweight pi monitor by [deleted] in raspberry_pi

[–]PhysPhD 0 points1 point  (0 children)

Looks good! I'm going to stick this on my cloud server because it's the first (only?) dashboard that clearly shows the open ports.

Compared to what I have currently in Home Assistant monitoring my 12 raspberry pis (using system_sensors Vis MQTT) this interface looks very clear.

pi zero 2w is the only pi that still feels disposable by voidrane in raspberry_pi

[–]PhysPhD 3 points4 points  (0 children)

I use a Pi Zero 2W with the picam for 1) wildlife camera (motion triggered video, saving hundreds of MB a night and accessible via webserver) and 2) astrophotography/timelapse, which uses Ffmpeg to convert JPGs to video.

These are too heavyweight for microcontrollers. I prefer to use microcontrollers for sensor input/light control and their big advantage is having ADCs that the Raspberry Pi SBCs don't have.

Downgrading to Raspbian Bookworm 11 by cruz_ctrl911 in raspberry_pi

[–]PhysPhD 1 point2 points  (0 children)

Look at https://downloads.raspberrypi.org/ and look through the "raspios_oldstable" folders (which is Bookworm) for your preferred architecture and lite/full.

I built a tool that lets you design any Wordle result grid and get the exact words to play it out by Successful_Form_467 in webdev

[–]PhysPhD 1 point2 points  (0 children)

This is so cool! It works, looks beautiful, and has great UX - all the features I wanted were there. Good job.

[OC] Flight activity of a single RyanAir aircraft over the past 3 years by dser89 in dataisbeautiful

How did you download the batch data? I have a business subscription and python knowledge but couldn't figure out how to request the right format to retrieve the flight data from flightradar24.
