Nickel iron is typically used for off grid solar energy storage. Weight doesn’t matter at all since the battery won’t be moved. The most important thing is lifetime. Traditional nickel iron batteries last for decades and can be refurbished.
UPS batteries need to be fully charged all the time. Lead acid batteries like to be fully charged. Lithium batteries need to be stored around 50% charge to have a long lifetime.
Mumble will do all of that except screen sharing. Only the server has to deal with NAT.
UHD bluray uses H.265. That’s one of the best codecs available right now. AV1 can do a bit better for certain content, but it’s not a huge difference. Basically nothing supports H.266 yet and AV2 is still in development.
Don’t rely on the VPN kill switch for torrenting. It’s not fast enough to prevent your IP from leaking if the VPN disconnects. The torrent client needs to be bound to the VPN interface. Transmission doesn’t have an option to do that, so you would have to run it in a container instead.
You could use it as a system monitor display or something. People have been adding small secondary displays to their computers for a long time. Back in the day, we would connect HD44780 character LCDs to the parallel port. There was even a Linux kernel driver for it.
That worked when TV was analog and they were running megawatt transmitters. It doesn’t do so well with the low power digital stations unless you are close to the transmitters.
It weighs almost as much as my 14" laptop. They should split it into two pieces so you can mount the computer and battery to your belt.
Wow, grabbing a base64 obfuscated URL with curl sending the output to bash is a huge red flag. I guess Mac users must not know anything about the CLI.
Never pipe the output of curl or wget to bash. You can’t inspect whatever it downloads before it gets run. If the URL is obfuscated, there is basically a 100% chance that it’s malicious.
There’s Mumble for voice, text and images. The server is self hosted and there is no chat history so it’s private. It uses Opus so the audio quality is very good without using a lot of bandwidth. For gaming, it supports positional audio and a HUD that shows who is talking.
For the projects using Discord for support, they should move to a forum.
It’s also most certainly against the terms of service for your ISP, VPN or VPS, so you could get your service terminated.
Running something like this will put a big target on your back. I hope you have your network locked down tight.
I’ve been using their access points for a long time. They have been working quite well. I do have an old WiFi 5 AP that’s starting to fail, but that’s not too surprising considering the age.
I’ve just been running the controller with a local account. Hopefully they won’t try to force me into using a cloud account.
If someone gets into your PC, you have much bigger problems than them reading the system logs.
It’s USD $53 on DigiKey and Mouser. That’s still rather expensive for an old single board computer, but it has a lot more IO than most other computers as well as a pair of real time co-processors for handling high speed IO.
There’s always the BeagleBone Black if you need a lot of IO. It has a 12 bit ADC too.
That’s not too surprising considering it has an LiFePO4 battery. 500 cycles is nothing for those.
You used to get a fairly significant upgrade ever few years for about the same cost as the old hardware. Transistors aren’t really getting much smaller anymore, so more performance needs a bigger die and costs more money.
The clock is only useful if the time is correct. They could at least put a small super capacitor in there to keep the time during short power outages.
Charge time depends on the UPS. The cheap consumer grade ones usually have a float charger that takes forever.
