Re: Most accurate gps chipset

Best antenna wins. Not always, As long as you have enough satelites you should get an accurate fix, but if you're picking up weak bounces off a building that could affect the accuracy. Most of the more modern chipsets can kick out updates at 10 Hz or better, so while not ideal for F1, might be usef...

Re: Update/Upgrade a group of Pi's from one Pi

I think there are 2 solutions: - Use something like apt-cacher-ng. Install it on a Pi, upgrade it (to acquire the packages locally). Then modify apt sources as required on the other Pis and upgrade them reusing the cache. Not automatic but probably producing a clean job. This is probably the easies...

Re: Extending Wireless Range

It is a moot point, because hacking the board on your own, is not breaking any regulations. Heathkit used to sell everything from breadboard breakout kits to Ham Radio Equipment, TV's and computers. The manufacturer that had the original board made, only have to live up to the rules for the FCC fil...

There is no LEGAL way to do what you want, directly. You could put an access point acting as a range extender somewhere between your router and the Pi, configured as either a wireless repeater or as a remote, wired, range extender. Plenty of legal ways for the OP to do what they want. They can use ...

Noises from the Pi board may also be an indication of a failing PSU (rather than failing Pi). The latter screenshots seem to indicate the Pi hasn't brought the wifi interface up properly, the likely reasons I can see for that are: older noobs/libreelec images, hardware fault on the Pi, or PSU fault....

That’s good news. Another problem: I can’t issue a cert to a device with a private IP. How can I work around this?

Re: Illegal instruction when running Qt5 application

I've seen similar errors when code has been compiled for ARMv7 targets when run on a Pi1 (which is ARMv6). Compiling on a raspberry may yield suitable code (although will take longer to complete). I'm not sure on options for cross compiling as it's something I've not looked at in much detail yet.
