I would learn how to convey my ideas in a coherent manner to other people. I also would like to learn how to create/repair my own electronics devices.

What areas of rhetoric do you have particular interest/concern with?

What type of electronic devices? Desktop computers are pretty straightforward. Laptops, netbooks, and smartphones are much more difficult, with smartphones being basically impossible to fix yourself (at least, anything glued onto the motherboard- -screens are pretty easy)

So it's more like.. set theory? They're mathematical objects composed of members, that are ordered with respect to each other in different ways. Specifically, they are ordered by binary operations, as far as I understand it. So like, "is greater than" is a binary operation, because it takes two arguments. Multiplication is another binary operation.

You can talk about binary operations by what sorts of properties they have, like associativity, commutativity, stuff like that. And different types of algebras—like groups, sets, rings, lattices—have different types of binary operations defined over their members.

That's my super rough explanation at least. I'm just learning about it myself!

I guess the areas of rhetoric I have the most problems with are creating a coherent "story" based on my worldview as a response instead of seemingly random ramblings.

The types of electronic devices I want to repair are big household appliances or audio/stage equipment. Basically everything with a THT layout as opposed to SMD layouts.

I honestly have no idea. I think that's one of the reasons I always stall out when I try to learn one, I don't have any real motivators to use it, so there isn't really anything to keep me going or work towards.

Well, the first thing that comes to mind is Kurdish, which I'm slowly working my way through. Other than that, I want to learn how to actually cultivate plants- I've never been much of a gardener.

Sewing aint too hard, man! I taught myself to hand sew last week in order to sew on a few patches and its pretty straight forward. The machine is a little more difficult but not with some practice.

Best way to approach this is to find a lefty friend with guns, ask nicely for them to take you to the range, and buy ammo for them and yourself. They will be open and train you to operate on a cleared firearm before you go to the range. I don't mind taking people to the range myself, but it's nice when my friends also pitch in for ammo costs.

ditto what mouse has said regarding sewing. My partner spent some time studying fashion and is handy with a sewing machine, so we ended up getting one at goodwill for $50. It runs great, and after she gave me a quick rundown, I was patching my clothes and even made a new shift boot (the fabric cover for the shifter) for my shitty car in a single night after one failed prototype.

Carpentry/woodworking, electrical engineering/troubleshooting, and how to work on my car. If I had to be dramatic about it I'm classically sick of being a white collar cog.

Yeah, I get that. Maybe you can try to use analogies to your own lived experience, or experiences that other people have shared/entrusted to you?

What's THT vs. SMD? I googled, but did not find anything fully explanatory

Fossidarity OP wrote

THT/SMD refers to the PCB layout method, THT is through-hole where all components have leads and are soldered through the board, this uses bigger parts. SMD uses very small parts and is very hard to solder by hand and the parts are placed on top of the board, not through it.

Soldering is very easy, just takes a little bit of practice. Let the iron heat up, put a bit of solder on the tip, touch it to the parts you want to solder (usually the component lead and the pcb's metal plating around the hole), and apply the solder inbetween the three, it'll stick when the parts are hot enough. If it doesn't stick, either you're not applying enough pressure on the iron or the contact point is too small.

The harder part is identifying why you're soldering the parts in that point of the circuit and how the components interact with each other (aka electronics)

Fossidarity OP wrote

Well modern things are also done by THT, SMD has limitations on current that's able to pass through it I think. And SMD is harder to replace so electronics which need to be maintained are also THT in general.
