Yeah, the current thinking is just to have the one magazine for now unless people have good reasons why that won’t work. Of course a lot depends on whether there are any active bugs federating between the two systems but I think right now things are copacetic.
Theories about the origin of copacetic abound, but the facts about the word’s history are scant: it appears to have arisen in African-American slang in the southern U.S., possibly as early as the 1880s, with earliest known evidence of it in print dating only to 1919.

Stephen Goranson says "there is good reason to think that Irving Bacheller invented the word [with spelling “copasetic”] for a fictional character with a private vocabulary in his best-selling and later-serialized 1919 book about Abraham Lincoln in Illinois, A Man for the Ages, and its currency increased by use in the 1920 song “At the New Jump Steady Ball”.[1] Alternatively, it has been speculated that it may have originated among African Americans in the Southern US in the late 19th or early 20th century, perhaps specifically in the jargon of Bill “Bojangles” Robinson, who certainly helped popularize it in any case.
Also, hashtags in kbin posts are recognised by mastodon/mblogs? At the moment, they’re not from lemmy (don’t know why). So posting out from kbin might also help in getting traction with the mastodon/mblog crowd.
One problem lemmy/kbin have at the moment for activism, is that smaller communities can get drowned out in the feed. You can of course sort by “New”, or “Hot” but might miss things, unless you’re actively checking the specific community. Same problem with mblogs too I guess.
Something interesting in the works in this regard is a Lemmy pull request to add “Best” as a feed sorting option, which ranks posts relative to their communities, and therefore should make communities equal on your feed. (See Pull Request). It isn’t finished yet but might not be far away.
Not sure about the hashtags, good question. There will also be separate posts on Mastodon – here’s an early example, guaging awareness – and it’ll be interesting to see what gets traction where
It’s a great point. This kind of legislative activism is frequently done in public on Twitter, Facebook, etc. as well so the risks are low in general but it’s still something to make people aware of. It’s a real contrast with anything that’s direct action, where the fediverse is a non-starter.
Is this not the same ESP32 with an antenna? Although I don’t know how the nRF52840 from your question comes into play here. Don’t you normally use an ESP or an NRF, and not both at the same place (with the exception of a gateway maybe)?
The nRF was a useless inclusion tbh, sorry for the confusion. The nRF already has an smd antenna.
The thing with those antennas is the size of the antenna vs the size of the module, it’s almost twice the size, negating any benefit of having such a small module.
Hence my desire to use an SMD antenna on a small board instead.
So you have these boards already? Or could you just get other boards with an ESP32 and LiPo charger? Because many already have a printed or ceramic antenna built-in.
Do you know of others with charge controllers with that from factor? The only one close to it I’ve found is the is the m5stack m5stamp, but it doesn’t have a charge controller.
I don’t mind creating the daughter board, I think it could be fun.
However I would be interested to know where I can earn more abt the topic of electronics, I am very interested in learning it and it would be nice to get some guidance. ty in advance
I… Don’t actually know, I’ve just cobbled together information over the years. My dad worked in an electronics workshop but never taught me anything. There’s a good intro to electronics course on udemy and if you’re serious about it, try get the book The Art of Electronics, its like an electronics bible.
and on top of that, various amateur radio pages, some are indexed in dxzone.com
there seem to be two hard limits on antennas in general. one is for approx lossless antennas that are large compared to wavelength: gain, beamwidth and size are related through diffractive limit en.wikipedia.org/wiki/Diffraction-limited_system it’s really about capture area, which is intuitive for things like parabolic reflectors, but for things like yagi antennas there’s some defined capture area that ultimately depends on their length
the other one is on non-directional antennas that are small compared to wavelength. basically one good antenna that you can make is halfwave dipole, you can try various trickery to make it smaller, but this comes at a cost of either smaller bandwidth or increased losses, or both to lesser degree. it might make sense to make an antenna with 70% efficiency which is 3x smaller for example. it all depends on precise requirements
at the end of the day the most important material in any antenna are tradeoffs
no, this is fine, you can find it in routers all the time (usually with printed antennas, or wire antennas)
so it seems, however remember that at microwave frequencies you might start seeing distributed elements as a part of matching circuit (patches, open or shorted transmission lines etc) every fraction of mm is critical. i don’t know what impedance gets this thing on output, but it might be very well non-real. it’s usually done so that everything is matched to 50 ohms
assuming that output is matched to 50 ohm, which is usually the case, you can use any length of coax, as long as losses don’t kick in too badly. this means you also have to make your antenna 50 ohms. i see you’re using ceramic antenna, which provides matching circuit for you, but there are other options like inverted-F antenna (3cm long) or even smaller zigzagged *inverted F antenna or halo antennas (some 2cm dia), which would require matching. tradeoff is better efficiency (less heating; one of these antennas wastes almost 40% of power) and the fact that you can make them on your own
Thank you for your detailed reply, I really appreciate it. It answers my question and raises a whole bunch more :D, I think I need to brush up on general RF and get a better understanding of how it actually works. I shall do some youtubing and reading on it. I found a really good pdf that discussed antenna design but a lot of it I didn’t understand, so I’m going to need to learn a bit more.
if you want to measure anything rf, you’ll need a vector network analyzer like nanoVNA (some $40), this will be very useful in tuning/matching antennas (and making sure you won’t get reflections that could potentially damage transmitter if you screw up badly enough)
antenna design is usually limited by one of these things: size, gain/radiation pattern, efficiency, bandwidth (fixed here, entire 2.4ghz band)
you can probably use off the shelf antennas used for drones if these are small enough for your application
soldering coax can be tricky, don’t melt center insulation. you’ll need to size microstrip line so that it’ll have impedance 50 ohms as well www.pasternack.com/t-calculator-microstrip.aspx
It’s faster than network data transfer. I don’t know exactly how fast can WiFi go, but most if the time it can’t even exceed 1Gbps. However, USB-C 4 V2 can reach 80 Gbps, and isn’t all that affected by electromagnetic interference.
For transfering a few photos, you won’t notice a difference. But if you need to back up a 256 GB phone, the difference in speed is actually big.
I just wish people didn’t spread so much missingormation in this community, in theory I would love to argue about things like Systemd, Flatpaks, Appimages, Gnome, KDE, Arch, Standalone WMs and so on but in practice it’s just a bunch of dushbags trashing on things they obviously don’t want to understand most of the time!
