the next dev, Hey this obscure feature probably doesn’t work, should I fix it… No, I’ll just patch “temporary-fix-don’t-use” and let the next guy fix it properly.

RF only has 2 components, Phase (frequency) and its amplitude. For Analog FM radio, you have a center frequency you tune to. The variance from the center frequency (phase) is the amplitude of the carried signal. For digital signals, you will have specified offsets from the center that represent specific binary codes.

Edit: as others have said, the tuning and demodulating are 2 different steps. Step 1 tune, When you tune you take the signal centered at the carrier, what the dial on your radio says, and recenter it at 0. Step 1 is the same for pretty much everything RF. The output is “base-band”. You aren’t going in and out of tune because for each center frequency, there will be an agreed variance (band width) allowed for the channel. The tuner captures this entire range and this is what is then demodulated in step 2.

Not my area of expertise, but these are my thoughts on the subject.

If you want mechanical clips on the connector assembly itself, you are probably going to want to stay away from mezzanine or back plane connectors. I usually associate these larger mechanical standards where the card itself has the mechanical fastening with screws, either to a chassis (backplane) or to the other board (mezzanine). You’ll probably find more luck with edge connectors, but that looks like another beast.

You also need to make sure you use something designed for multiple cycles if you plan on swapping frequently.

If I was looking for something I would just brows samtech, molex, or just digikey and filter until I find something that suites my needs.

For hot swap, you also have to make sure you have something that is designed for that, usually that means some longer pins on ground to make sure you’re not having any surges on data lines.

If alterations are allowed, fried rice is better with old rice. I think leftover mac & cheese fried with some garlic salt is better than fresh.

There are some desserts I make that need to be chilled for a few hours, those are mostly better after a few days and the porous parts can spend time absorbing flavor.

From the last eclipse, the difference between totality and not totality is night and day. Even at 99% you can’t take the eclipse glasses off. The closer you get the more of the secondary effect you can see, like the crescent shadows, and the overall dimming. here is an interactive map. The percent for each of the lines is on the right and bottom.

Glad it worked. It looks like its for getting the big stuff while communityboost is designed to help find the small.

From the way I read it, you create a user for the tool so when you submit your instance, it can run on your instance. One of the users chosen at random is here https://discuss.tchncs.de/u/communityboost

You can read a discussion about it here https://pawb.social/post/4136386

I also came across https://github.com/Fmstrat/lcs

Edit: Looks like https://sh.itjust.works/u/iso might be the user behind it.

There is a tool I’ve heard about that subscribes to remote communities for federation until a real subscription. https://boost.lemy.lol/

I’ll start off with your questions are a outside of what I know well. In general to do stuff with electronics, you don’t need to know the physics behind it, but the equations that pop out. Mainly V=IR, Almost everything goes back to that. Behind the scenes are lots and lots and lots of differential equations. Alpha Pheonix has a few good visualizations for resistance. He has a water based demo to visualize voltage and resistance, and a maze demo showing how electricity “finds” the path of least resistance. ElectroBoom probably won’t teach you too much, but can show some interesting things you can do. EEVblog has some good lectures. For specific applications Digikey and Texas Instruments have some basics, and there are many lectures online available.

I think the questions you asked are a little more on the physics side than the electrical side, and the specifics I think of as a dark art that comes with experience. In general most capacitors you see are blocking DC on an AC circuit, coupling capacitors that are smoothing the power circuit, or capacitors to control/tune something specific. Those control values would be given in a datasheet. Resistors are often going to be current limiting, voltage dividing, or “pulling” a high impedance signal. To design something you often just need the rule of thumb, and not necessarily a deep understanding of “why”.

I guess my question to you would be what are your goals? Do you have a project in mind? Do you have a technology, Analog, RF, MCU, FPGA, embedded design? I tend to learn a new thing better when I have an end goal or project to work towards. Depending on where your starting from, a pi might be a good place to start too. You still have most of the I/O and busses of an Arduino, but you can program everything in python, and you have the resources of a full OS too.
