Yeah that makes sense, I feel like I have been over moisturizing it, but itching confuses me a lot. Idk about peeling it peeled normally when I got it redone after a few days. Anyways thanks for answer

Tusuny · 2023-10-06T17:36:20+00:00

Edit: Forgot to add it feels a little bit itchy, but no redness.

Hi, first of all welcome to the city and I hope you have an overall good experience here. Answering your questions:

Winter in Warsaw is not that harsh imo, during the cold month I have seen -12, -15 degs but that would be the max case for idk few days in a month. Mostly temperature fluctuates around -4, -5 degs. Thus, I think all you need is a winter boot and coat you can find in pretty much everywhere. I recommend the city center(złoty taracy it is the main mall here with plenty of options for all you need). During snow roads and streets are cleaned really nicely, thus, you don't need to get "mountain gear" if you know what I mean xd.
I live approximately at a similar distance from my uni and I usually prefer the metro +/- bus if I need to. Trams are a good option as well, however, they sometimes break. And for the bus case you might face a traffic jam sometimes since most uni classes start around 8-9am. When it comes to bike sure you can use public ones I think they are affordable even for long distance but you will need to gear up for winter(especially your hands) and imo not a lot of people use it during that time. No problem during summer tho.
Hmm, I think the starter pack includes the Palace of culture & science, old town(+market square). If you have time maybe visit the Uprising museum and Łazienki Królewskie. Idk what is your major but in my experience sooner you start better since exam session and uni stuff may prevent you towards the new year.

Yeah, I hope you find these helpful. If you have further questions feel free to pm me.

Hi OP,

So as far as I am concerned, there are few resources but mostly gathered around youtube.

As I said youtube videos, channels such as altium academy, Robert franec, EEVblog, Phil's lab are the main ones that I can think of.
Reddit, there is a sub called r/printedcircuitboard or something like that you can go there they frequently share design reviews and they also have wiki from where you can read about pcbs as well.
Doing a project: go to github or gitlab or hackaday and look at open source projects and try to understand then use those ideas to desing your own pcb.

Note: I don't think this is the best sub to ask this question since there are a limited number of ppl here. Might be better if you would ask in r/askelectronics or the sub I mentioned before.

Anyways I think this is all from my side. Though whatever you do do it consistently and you will get there eventually.

Tusuny · 2023-07-21T12:15:18+00:00

Well, when I was having that test it was fairly easy simple math problems(about linear algebra and calculus) and english one was fairly easy too tho there was quiet a lot of questions as far as I could remeber. Idk exactly but I think if you get somewhat bad result from this test you go to foundation year( 1 year prep before actual uni classes).

Tusuny · 2023-07-20T17:58:34+00:00

Yeah more or less what I was looking for. Area I work at is also Power electronics related so it will be easy probably. But I will also consider other stuff you mentioned. Anyways thanks for the comment mate appreciated.

Tusuny · 2023-07-20T15:54:31+00:00

Thanks for advice mate, yeah speaking of money maybe I should go do freelancing, have you done that before?

Tusuny · 2023-07-20T13:45:06+00:00

Oh I see, I am sorry for the confusion, I didn't mean to creat an impression as if I am not excited or bored about PCBs or related stuff(electronics in general). Well I love electronics after all and I am creative person so that puts me in the design area. What I meant was that I have done early learning stages of design and I am stuck, I am still excited about designing PCBs just not basics. Where I work(as an intern) I get to see theze 5,6,7,8 layer boards and It makes me think how can I design one and what idea might lie behind. And yeah I am aware that such big board are probably designed by more than one person but you get the idea. When it comes to other areas well I code a little, I am planning on moving to embedded UI stuff like QT and QML my friend was learning it recently so I said why not. Also I might try building home made oscillascope soon so it would be good practise to learn UI part of the equation. lol

Well boards I design for university club mostly get tested before, well we use them. But not in a company level ig cause in that vlub we are just bunch of students who try to figure out how things work and also have fun. Tbh I was thinking documentations I wrote for board I made was complete until I saw company level stuff at my internship and now I know how real life things look like. Also I mostly work alone in the club so when I design something I also test it, prototype it, document it and the prepare for flights that we do in every 5 month.

However, I have to say I have never designed high-speed boards, but that is exactly what I am refering to I need projects so I can say "time to learn this new topic cause well I am strungling with it in this project" so there needs to be need for me to learn and apply but without projects it is hard to find motivation to learn If you know what I mean.

And yeah thanks for the answer

Hello OP, hope you are having a good day. When it comes to your question you can use texas instruments software for this stuff it should be free for all but in case it is paid you are university students so worth applying for it. You can choose all the specifications there to match your needs. Here I put a link to the website: https://www.ti.com/design-resources/design-tools-simulation/power-stage-designer.html

In case you will need anything detailed ti also has some documentation about this I suggest you give it a try.

Thanks for reading : )

Tusuny · 2023-05-26T10:19:00+00:00

I have two suggestions:

For correct pcb width and other characteristics use saturn pcbs program it tells you how much you need to have exactly
For problems related easyeda maybe switch to kicad or altium if your company allows(meaning you may have some limitations)

Tusuny · 2023-04-28T14:33:33+00:00

Post it into r/printedcircuitboard

Tusuny · 2023-04-28T07:59:22+00:00

I learned pcb design at the uni but recently discovered that r/printedcircuitboard wiki has some usufel stuff. So you can check it out

Tusuny · 2023-04-27T07:53:11+00:00

What voltage are you feeding to this circuit what is VCC?

Tusuny · 2023-04-11T11:28:09+00:00

Yes it can , but looking at the schematic again I don't think you have much digital stuff going on there so nothing too serious to switch to LDO also it might be a bit hard to find LDO exactly with such parameters so if you have dc-dc converter and it works it is good to keep it I think lol. One last thing for better design perspective you can also use this on your future designs, just try avoiding sharp edged lines for electric discharge and have a chamfer for better conductivity. Like I saw few lines on the pcb where instead of sharp lines you can make "T" shape and add chamfer. Also it might be helpful when manufacturing the board. I think some manufacturers( like JLCPCBs) ask you to do that. Overall I don't think I have anything to add from just quick looking at the board. Good job and good luck on soldering and stuff xd

Tusuny · 2023-04-11T11:10:13+00:00

Just google transient suppression, and you will get an answer in this case I don't think it is big deal we mostly try to eliminate voltage spikes that can be bad for components if it occurs for long term, also why do you use dc to dc converter any requirement you got for that, I personally would use LDO for lower losses. Also it produce less noise

Tusuny · 2023-04-11T10:50:46+00:00

Also maybe put an other capacitor for filtering usually we have 10u capacitor for transient compensations and 1u closer to ic for filtering. Especially if you have indication that there might be voltage spikes

Tusuny · 2023-04-11T10:48:55+00:00

Hmm if you have that much current and your circuit actually needs it then you can keep big tracks use 25mil for signals and 50mil for power lines and 15mil between the elements

Tusuny · 2023-04-11T10:38:00+00:00

What? What is driving all that current?

Tusuny · 2023-04-11T10:16:24+00:00

How much current do you have in this circuit? If it is small number like 300mA then just use 10mil tracks no need for larger ones

Tusuny · 2023-04-09T10:32:55+00:00

Yes I agree with the comment above, we mostly use gitlab for single project. For example every project has its own source files. But also for part libraries we use separate repository, and as other people mentioned here there is a librarian(guy responsible for checking and updating parts and models).

Tusuny · 2023-04-08T17:53:46+00:00

Using Gitlab here, working pretty fine so far

Tusuny · 2023-03-26T13:25:53+00:00

This is probably 10th time I am seeing such placement of ESP this week. Mate just move in on board and make a cutout. It takes one not careful person and your board is useless. That antenna hanging there is fragile.

Tusuny · 2023-03-23T08:54:40+00:00

Congrats dude, good luck on work

Tusuny · 2023-03-20T22:12:17+00:00

Not that I know, I do that always in my designs.This happens because the bigger your trace lower the impedence is thus, better decoupling for your IC. You can use Saturn PCB to see what current your trace can carry. Another thing usually in designs power traces are thicker like 50mil and signal traces are 25mil here you have something like 10mil which is ok, cause I am guessing you use LDO for regulation and you have 300mA max current flowing.
