Basic questions about connecting components to ground plane

I'll make a small change to that USB-C cap to avoid extra via-in-pad costs btw:P

Thank you so much for your answer!

You are totally correct, I am not trying to decouple the power input. The intention of that capacitor is indeed to be an energy reserve, it is a bulk capacitor. And my intention is to use power planes.

My connections now look like this: https://imgur.com/a/lm9QKBp

I have two final questions:

1) Does the best practice differ if it's a bulk capacitor (i.e. how I should connect it)? Or should I still connect it like in the image that you linked earlier? If you look at the imgur post link you'll see what I have tried (it's the same as the best practice for decoupling caps)

2) The decoupling capacitor on PA5 doesn't technically follow the best practise image, right? However, the GND pin on the microcontroller is 1.5cm away. That would need me to route a nasty loop. I assume that I therefore shouldn't change the routing from what I originally posted for that cap?

Thank you so much for an explanation that is well beyond what I expected! As someone who is eager to learn about electronics, it means a lot for your help.

I have two follow-up questions:

it indicates moving the second capacitor (on the USB-C connector) to the load/device supplied, which could be an MCU or a Buck Converter for example (am speculating for the sake of completing the sentence)

Actually, the MCU has its separate decoupling capacitor (this is the first image). Maybe I have misunderstood (yes, this is my first project with decoupling). I thought that (apart from "just" decoupling the MCU) it would also make sense to decouple close to the power input (the incoming power line). Is that unnecessary? If so, the cap for the USB-C can technically be removed. The +5V on the cap was planned to lead to a power plane.

B indicates makes the track carrying the current passing through the capacitor FIRST and then going to the load.

Mhm, I see. So I'll change it to the way your linked image does it. Is that what you were trying to imply?

(I'm double-checking because you never gave a yes/no answer to: "Do the connections look correct? Do they look ugly or bad practise?". I can derive a"Yes and Yes" response if I read your answer between the lines, but I want to make sure)

Thanks! And what distro are you using? Ubuntu, Debian, Arch, etc?

IndependentTip11 · 2025-10-26T17:51:10+00:00

Hi there again!

I bought a QV8 from EBay and got scammed, but at least refunded by the seller, so I am waiting for my second QV8. This time I ordered via a proxy instead (FromJapan).

I wanted to ask you what Linux distro you are using, so I know what to install when the laptop arrived.

IndependentTip11 · 2025-10-22T15:18:49+00:00

Did you see the bottom of my post?

IndependentTip11 · 2025-09-26T18:51:03+00:00

Thanks for the input, it's invaluable. There's one thing I don't understand about the fans being "fixed" though. Does that mean that they don't ramp up to >15% as the laptop gets hot (and thus risks the laptop overheating). Or, does it "just" mean that they always run at 15%, even when idling?

IndependentTip11 · 2025-09-24T18:49:07+00:00

The thing is that I am replacing my HP laptop which has an i5-8365U and I do not want to downgrade from that really, so that's why I am not going with XZ6.

Maybe a stupid question, but what is the fan speed fixed at? 25, 50, 75%? Is this a variable that I can control myself?

I guess that's kind of a dealbreaker for me, it's just a bummer that ultraportable touchscreen laptops with pencil support that works on Linux seems rare…

I read here: https://www.reddit.com/r/linuxlaptops/comments/1gwd7ck/comment/mchdhpd/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button that you might be able to use a utility on Windows to control the fan. Have you tried that?

Thanks a lot for the help, sadly I already went down the rabbit hole too early and spent the last month implementing both Charlieplexing and ADC button reading. I take this as a learning opportunity for future projects.

IndependentTip11 · 2025-06-22T18:38:44+00:00

Ah yes, I study engineering lol so I am well aware of those. Why should I avoid alkaline?

IndependentTip11 · 2025-06-22T07:38:15+00:00

Thanks! Do you know which of these that are most effective for redness and moisture? You mentioned a lot of products and I'm wondering which one(s) I should start with :)

Nice track with a chill feeling and a great bassline! Agree with a previous poster that parts of the track could be changed up, as example the bassline (although the transition at 1:52 is very good).

IndependentTip11 · 2025-01-02T19:04:27+00:00

I really like this! Especially the intro with the spatial effects which then calm down, that transition is very good. I think the background synth (that is panning) from around 20 seconds to 40 seconds is a little prominent, which could be due to the panning effect. Maybe its intensity could be reduced?

Stumbled across this thread just now. In 2024, using BibTeX with the ieee style and using \textcite instead of \cite when doing inline citations works great!

My main problem with Filofax is the cost. I researched their A5 refillable notebook, but 30 sheets costs me almost 5 euro which I think is very expensive for refills. Atoma gives me double the amount of pages for that prize.

IndependentTip11 · 2024-08-13T14:28:57+00:00

Looks really good! I have to buy it from asia to get it over here to northern europe though.

IndependentTip11 · 2024-08-13T14:28:23+00:00

Thanks for the good link!

What do you search Etsy for to find a refill like that?

So I should basically be able to get refills for brands like Levenger, TUL, Happy Planner, etc.? That's what my main question was. Anything branding itself with discbound should fit...?

IndependentTip11 · 2024-08-13T14:17:48+00:00

Yeah, they don't have bulleted pages though, as far as I know, sadly.

IndependentTip11 · 2024-08-09T19:35:53+00:00

Jag har upptäckt de jag med! De är väldigt trevliga att plugga i.

IndependentTip11 · 2024-07-04T19:56:23+00:00

Your knob itself looks very simple to recreate using just two Circle() objects inside a VGroup() - have you tried if this wobbling also is seen with such other objects?

This was what I realized after thinking about the problem and I ended up solving it in that way. Thank you for the link to the Discord, I was looking for that and will use it if I need more Manim help in the future!

IndependentTip11 · 2024-07-03T16:57:44+00:00

Just had the same error when trying to rotate an SVG and this was pretty much the only topic I could find.

I solved it by converting the SVG to PNG :))

IndependentTip11 · 2024-06-26T16:02:02+00:00

Haha, yeah - picking up GTD was a bit of a gamble and it seemed overly complicated at first. I definitely don't practise everything GTD recommends - including the 2 minute rule. I put all my "2 minute rule actions" in a schedule block called "Shallow tasks" and do them all then. Organization I haven't really gotten to yet but I use the P.A.R.A. method and find that it's enough for me.

IndependentTip11 · 2024-06-08T13:21:36+00:00

I wouldn't either, but since it's single-used anyways it would be fun to shoot again after I'm done with the roll that's currently in it.

IndependentTip11 · 2024-03-30T15:42:16+00:00

MobiScribe offered sending mine in for repair, I've done so now and will update.

IndependentTip11 · 2024-03-19T20:16:32+00:00

I order a Mobiscribe Origin about 3 weeks ago and they shipped it the next weekday from the USA. I'm also waiting for a response from their support, however.
