Just use a couple of zero guage wires. Problem solved.
Horse medicine? Florida? Something sounds familiar, but I can't quite nail down what..
Make note of the instances you are on. Communities with the same names can be radically different across instances.
Each instance may have their own collective view on what is right or wrong, good or bad. For example, I saw that you mentioned the "T" word (or was in a discussion about it) on .ml the other day and that is a recipe for an interesting discussion. You do what the heck you want, but each community will have their own special reaction.
I stumbled into lemmygrad a couple of years ago, somehow. It didn't take but about 5 mins for me to be labeled a fascist baby killer.
If Broadcom takes over Intel, get ready for a wild ride and don't expect any kind of innovation ever again. If there ever was a backdoor in Intel CPUs, expect it to be opened up and used for licensing extortion. (That seems far fetched until you realize how fucking shady Broadcom is.)
While I shifted to the AMD bandwagon a while ago, I really wanted Intel's GPUs to develop more over the next decade and split the market up a bit more. Sigh.
Same here. Nerd blood runs deep in families.
(When the power brick blew out for my Atari, my dad simply cut open a random spare and re-wound the transformer to match the correct voltage. It was the neatest thing I had ever seen at that age.)
Any time! Just learn what you can now and pass the knowledge forward later.
It might be worth it for you to get a ham radio license. If the low power modules work for what you need, that is just fine. For the distances you are talking about with cattle fields, being able to legally transmit at over 1000 watts could have perks. (I jest, but having a little more power, in the 1 to 2 watt range, might be practical.)
At a minimum, a portable ham radio might be a good safety tool depending on the size of the ranch. It would be hella more reliable than CB as well.
Lol! I suppose the million dollar question is if you are generating interference. You are allowed to have a shitty design that works as long as you aren't causing grandmas pacemaker any problems.
That book is a great start, actually. AC theory is critical in understanding RF circuits.
I noticed there were dedicated sections in that book for LC/RLC circuits. In regards to RF, you might see those referenced as resonant tank circuits, so keep that in mind as you move forward.
You aren't going to see too much about impedance matching until you start working with transmission lines, as far as I know.
I just looked this up and read through it and it seems like a good intro. It'll be confusing unless you have a basic understanding of AC: https://resources.system-analysis.cadence.com/blog/msa2021-understanding-impedance-matching-in-transmission-lines
Start looking for YouTube videos with Eric Bogatin. He is a professor at CSU Boulder and has re-written the book on proper PCB design. (He does have a book, but he debunked a ton of old theories on high frequency board design and signal integrity.) If there is anything you must do, is follow his work on ground and power plane design or anyone that references his work. If someone uses a ground plane to just "fill in gaps" or have it act as a generic fix-all "shield", ignore them. (Many RF/HF myths came from the way boards were fabricated, not because of a specific circuit function.)
Once your signals get past a certain speed, you need to learn how electricity actually flows while understanding that both AC and DC theory applies. If you didn't know that energy flows in the field around a wire, you probably need to step back a little before you step forward. (Reference Veritasium on YouTube: The Big Misconception About Electricity )
You don't really need to get into heavy RF theory, but it helps. If there is anything you must learn about, it's impedance matching and why it matters. To summarize quickly, if there is an impedance mismatch between your transmitter and your antenna, you could easily blow out your transmitter due to excessive power draw and signal reflection. (That is somewhat rare for low power devices, but not uncommon once you start to transmit above 5-10 watts.) If a device needs an antenna, use it, even if were are talking about something as common as WiFi.
For your first designs, respect trace lengths and recommended components. Most of all, respect the keep out areas around an antenna diagram and ensure your ground plane is properly designed and away from the antenna. There are many shitty designs that do work, but you want to strive for precision for your first few iterations.
Also, decoupling becomes more than just a thing to do that might improve stability of your MCU or other components. It's entirely possible to get the rest of your PCB resonating which will cause all kinds of noise. This is partially negated with proper decoupling.
High frequency design just takes a little more care. Just remember the basic saying: Everything is a resistor, capacitor and inductor.
Now, if you just work with modules (and ESP32 with an integrated antenna comes to mind), almost all of the hard work is done. Make sure you have proper clearances, slap the thing on a board and you are good to go.
For the absolute basics, impedance matching with proper antenna length is what you need to learn first. (Receivers are much more forgiving than transmitters, btw.)
I am fully aware that some key details are missing here and just summarized as best as I could. If something I said turns out to be misleading, that isn't the intent and I apologize in advance. The intent was just to kick start more curiosity.
Edit: RF design and high frequency board design share some design considerations. Not all signals on an RF project are going to be high frequency and not all high frequency designs use RF, but, all high frequency designs can quickly become RF designs.
Also edited a time or two for clarification, grammar and spelling.
I suspect many people aren't talking about this because many Lemmy users don't use the platform.
Just use an alternative service instead of trying to find more ways to use Musks personal propaganda platform. Honesly, It makes more sense to open up apps like this again, quietly, since it was was a serious strategic flaw to block it in the first place.
I don't disagree with the concept of this front end, but there are just better options out there.
Fuck Nvidia. I am not buying any more of their products and it's disgusting that they manufactured a shortage of the 50 series.
Don't buy their shit.
