Is it Hell Let Loose? I started playing it since they support Linux now, very well done Battlefield-like game. I haven’t played much BF since 1942.

usrtrv,

If you’re not just being facetious, areweanticheatyet.com is a good source.

According to them ~58% of anti-cheat games work. There’s been a large uptick of anti-cheat support since the Steam Deck.

According to ProtonDB, 86% of the top 1000 games on Steam function (Silver+ rating). It’s a pretty safe bet that the most of the missing 14% is probably due to anti-cheat.

usrtrv,

This. College is useful for trying out difference career paths and subjects. But hopefully you end up enjoying something that will pay off all the debt you just accrued.

usrtrv,

Seems like a regional issue? Steam has the same price as any other store here in the US. Excluding subscriptions.

Is “harvesting” small amounts of electricity a fools errand?

Serious question from a beginner in electronics. For reasons I do not fully understand, I have become fixated on the idea of collecting small amounts of electricity from “interesting” sources. I don’t mean “free energy”, instead, I mean things like extracting a few mV from being so close to a AM radio tower using two...

usrtrv,

The best advice I’ve seen online (ok, it was ChatGPT) is that it’s just not worth it to work with such small amounts of electricity, because the equipment required is too expensive and sophisticated (e.g, devices to read the charge of a capacitor without discharging it) to make anything that’s efficient enough to be worthwhile.

I guess ChatGPT has never heard of passive RFID tags? LLMs have some good uses, but they’re not great at a lot of things. You can’t really advance science and engineering by strictly regurgitating scraped text.

There are reasons to grab small amount of electricity from the environment. Why have a battery in a pacemaker if you can generate power via mechanical forces? It really just depends on the use case on how practical and feasible it is.

usrtrv,

They do use capacitors to keep power. Here’s a simplified diagram: https://lemmy.ml/pictrs/image/eac4a0e0-12c0-4117-afac-dc2a31b43b0d.png

The most basic RFID tags will just send back an ID. The complexity can shoot way up and have all sorts of integrated circuits, mostly around encryption.

I guess it’s more of a semantic argument at this point, but would you not consider a tiny computer (RFID tag) that powers itself solely off of radio waves not a form of energy harvesting?

usrtrv,

That’s a good point. What about long range RFID skimmers? You could argue the tag wasn’t designed to work with a skimmer. I guess that’s more like energy injecting?

“Sure, you can do everything it does with a phone”

No, you can’t do everything with a phone. A phone doesn’t have the same radios, GPIO for expandability, IR transceiver, etc. Not to mention the radios a phone does have doesn’t like it when you start forcing it to do fun things.
