The relay will cause a short voltage drop when switching. This could be a problem if your circuit can't handle a short voltage drop.

Probably the Mean Well has adjustable output voltage. If you can trim the output voltage of the power supply to a higher voltage than your battery, then you can probably just run each power source through a diode and merge them after the diodes.

The "digital devices" tuners are pretty solid.

I would not suggest getting the PCI express tuners as the driver situation is just as bad as with the other manufacturers, but if you get their IP tuner you should have something that lasts a long time.

In my experience the whole DVB driver situation on Linux is really messed up. Seems to be partly because of difficult communication with the linux kernel maintainers and partly because of lazyness of hardware manufacturers (they don't care). Another problem is that DVB really runs out of favor. It is not "cool anymore" as everyone uses streaming services nowadays and so less and less "spare time developers" still care about "TV". This even seems to be visible in less and less DVB hardware still developed.

I would just give up on the idea to still run a tuner directly on a PC. Get yourself a "SAT>IP" tuner, add it to your network and stream your TV programs over your home network.

Edit: It is even possible to set up your own Sat>IP server with "minisatip". So you could get a mini PC, plug the tuner(s) you already have, only care about getting them working there and bury this dedicated TV streaming server somewhere in the house.

Thanks. Sounds interesting. Unfortunately I'm still on Nvidia.

Thanks for sharing. What is this "FSR"?

Maybe they target one of those "immutable" distributions to be able to bring invasive anti cheat to Linux. Meaning the same spyware as they develop for Windows based on a closed source, signed, kernel module.

For me this even smells like "kernel module that has to be loaded". I highly doubt this is even worth trying. There are already only a few Linux gamers. How many of them will switch distribution just for a game?

"Popular version of Linux"? I smell really bad things. They could lock this down to just one distribution.

But I don't want to deal with Windows at all. Something like this may be acceptable for existing "pre Linux" hardware to have a solution after migration.

But I need new hardware in an environment where no Windows is left.

Thanks. Nice to know. So I'll not get a WD, then.

Not installing through a package manager brings many disadvantages of Windows.

If the developer itself ships the binary, then I can not know for sure that nothing "slipped into" the package that is not in the source code. Malware is still not that common on Linux but I prefer the distributor to build packages on some kind of build system over the developer building on the PC where noone knows how well he cares to not risk installing any "fishy" software.

I would recomment to try Kicad for this. It is free and should do just what you want.
