“Finally, the firmware now supports authenticated OTA updates, so future builds can be installed through the browser instead of connecting the board over USB.”

What does that mean?

Looks pretty cool, though kinda "cheating" by pulling from adsb.fi - though I think you'd need something a lot more powerful than an ESP32 to receive and decode ADS-B ;)

I would actually expect the math to decode ads-b traffic is substantially less complex than, for example, a TLS connection.

It is trivial to decode, but don’t forget that tls is extensively optimised on most networking stacks.

Using ADS-B and calling it a "radar" feels wrong to me.

(But is is a cool project)

Agreed, and even SSR always felt like cheating imo. I wanna see someone build a primary radar on an esp 32.

Actually possible to receive and decode ADS-B on ESP32, but MLAT is failing (tried hard but not found a trick yet).

Biggest problem isn’t that it’s not powerful enough, but the USB port bandwidth don’t match most SDR.

Using some clever tricks you can receive parts of the message on a slower USB and be able to decode ADS-B

Why do you need to send the samples over USB?

greggsy•about 2 hours ago

You could fit a pi zero and rtl in an enclosure not much larger than the one they’ve printed.

Perhaps I didn’t read it thoroughly enough but it seems that lat/long of the “radar” are expected to be entered by user, I think using wifi positioning could be of great assist and could be done from mcu itself without involving web portal, though maybe portal already does it (didn’t get to see it)

Well, a radar-like display, then. But not a radar.

radar *display*

making esp32-based radar emitter would've been cool, tho

Its an amazing work

ADS-B is not radar, despite ATC calling these sorts of things “secondary radar”.
