- Comment on 5 pin connector recommendations that have both male and female sockets available 3 months ago:
10A is a pretty big ask. You might want a few more pins to spread that current around. What are you other pins used for. DE-9 is where I would probably start.

how about jekyll? Lots of customization available.
- Comment on how the heck does FM work,? 5 months ago:
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.
- Comment on Good right angled board to board connectors 5 months ago:
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 samtch, 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.

I have a sheet of paper that lives on top of my power light. Its soo bright, and its not even in my bedroom. I should throw a resistor inline there, I just can’t be bothered.

My upgrade cycle is about 10 years. So many more plain options last time. I went with a Roswell R5 last time. Went with a Fractal Design Define R5 this time. Fractal was the only quality plain case I could find. My brother actually has a 330R.

Some fan LEDs are directly connected to the fan power, so you can’t always turn them off.

Don’t know where your looking. Most are. - Comment on [deleted] 1 year ago:
They were all that I could find that I would call a quality case. I went with the Define R5.
- Comment on [deleted] 1 year ago:
I like the way you think, but then you probably have to deal with $erver components.
- Comment on [deleted] 1 year ago:
I paid way to much for a Nice solid case. It was just such a pain to find. I wound up with a Fractal Design Define R5.

No. I’m already on mint, and I’m commenting from a furry instance. How much credit do I get?
- Comment on [deleted] 1 year ago:
They used to.
- Comment on [deleted] 1 year ago:
So long as its metal, keep on going. Plastic has an unfortunate habit of breaking when its old.
- Comment on [deleted] 1 year ago:
No, I’m saying you just say just search, and even those searches have to be manually sorted through. I’m simply pointing out even with filters you have to manually pick through the results to have a real filter. There are plenty below the top row that have open sides too.
- Comment on [deleted] 1 year ago:
System integrators seem to be the exception.
- Comment on [deleted] 1 year ago:
The first 4 results there have mesh side panels…
- Comment on [deleted] 1 year ago:
en.m.wikipedia.org/wiki/File:STSCPanel.jpg looks like a pretty nice setup. No excess LEDs in sight.
- Comment on [deleted] 1 year ago:
If they cycle through do you get all of that at the same time?
- Comment on [deleted] 1 year ago:
If I could have gotten the boring cases that HP, Dell, and the others make, I would have. But other than system integrators, you can’t really find stand alone plane cases.
- Comment on [deleted] 1 year ago:
When I put my new machine together not too long ago I actually went with the Define R5. The only part I couldn’t get away from LEDs completely was the MB. I don’t think I could find the solid Define7 at the time.
- Comment on What is enterprise.lemmy.ml? 1 year ago:
Looks like a test instance. URLs are read from the end to the beginning, so enterprise.lemmy.ml is a domain controlled by lemmy.ml. As that is the instance that the main developers control, it would follow they have a testing environment. In addition. Almost all the posts, users, and communities seem to have “test” as part of their name. It being the instance controlled by the developers is why lemmy.ml is always a link, while lemmy.world would need to be formatted as a link to get a link.

Glad it worked. It looks like its for getting the big stuff while communityboost is designed to help find the small.
- Comment on Only able to see subscribed communities 1 year ago:
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 discuss.tchncs.de/u/communityboost
You can read a discussion about it here pawb.social/post/4136386
I also came across github.com/Fmstrat/lcs
- Comment on Only able to see subscribed communities 1 year ago:
There is a tool I’ve heard about that subscribes to remote communities for federation until a real subscription. boost.lemy.lol
- Comment on Is there a way to have a link to a post resolve to a users home instance? 1 year ago:
So a hacky solution that uses lots of javascript to search your home instance and re-write the page. Got it.

- Comment on How can I get better at remembering names in video games? 1 year ago:
I don’t know if I have any actual facial blindness, but I have a terrible time recognizing people. In tv shows, it takes me half a series to recognize the main characters by appearance alone. I think I recognize features of someone more than the person. I have terrible name recall to the point I don’t usually ask people their names because I know I’ll forget it almost immediately. I also almost never recognize people out of context.

I stopped getting older after graduating college.
- Comment on How should I get started? 1 year ago:
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”.
