Shameless plug: I wrote the decoder for METEOR satellite signal, which works on RPi among other things - https://github.com/artlav/meteor_decoder

That satellite is digital, so images are of much higher quality while being in the same band and needing the same equipment as NOAAs.

Nice, thank you! I currently only have a v-dipole antenna with which I previously tried decoding METEOR data without much success, but I'll be sure to try it on the Pi.

PI-4 Prototype! added FPGA, more GPIO pins, SATA connection and more...

April's fool joke as professional as possible! I hope Raspberry Pi team consider putting some of those capabilities in the next Gen. FPGA would be most welcome.

Well, if you need an FPGA, you can already add it ...

Yeap! but I think one benefit of an All-in-one solution could be that the community takes step in a new direction. people with high skills in coding would do the hard job of developing ready to use (or semi-ready) tools, addressing broader range of applications.

Raspberry Pi 4 B offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 B provides desktop performance comparable to entry-level x86 PC systems.
This product’s key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, up to 4 GB of RAM, dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on).
The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.

Hm, i would have preferred a more compact version of Compute Module or Zero. Trying to scale up the performance feels like a wrong way to go these days.

There are other boards around though that try to be less versatile and focus more on certain performance attributes.

I don't quite get it... for the device to be vulnerable to attack from outside, it would have had to have its own port forewarding from the gateway, otherwise you could only get to it if you already got into the network. Unless it was compromised already before it got into the network.

Didn't know the Raspberry had got into orbit, good for it!

Seeing how popular live game streamers are these days, I was wondering if it would be possible to live stream outdoor activities with a Raspberry Pi 4. In my case, the activity would be gliding, puting some extra restraints on the project. At this moment, I am unsure whether terrestrial 5G networks are accessible from 5000 feet or so. If not, I expect satellite internet coverage to become available in the not so distant future.

I am thinking of a 2 camera setup. A main one and another for a smaller inlet on the screen. Also, I want to be able to create an overlay to display telemetry.

I think it would be possible to parse user comments and extract information from it like latlon's.

Does anyone have experience with such a hobby project? Do you think it's doable? What OS would you choose?
